What is a Chemistry Filter?

What is a Chemistry Filter?A chemical filter or chemistry filter is a must for every chemistry student. A chemistry filter is a unique device designed to filter out the impurities in your water and to make the water taste better and give you health benefits that it did not give before.The first question of what exactly is a chemistry filter? In simple terms, a chemistry filter filters out impurities and bacteria that may be contaminating your water. Before chemicals were introduced into our drinking water, the only impurities that made it into the water was microscopic as it gets from the source.When the water reaches our system, it gets filtered and cleaned and the impurities that are in the water are removed. This also gives you the benefit of more oxygen and purer water. Now, with the introduction of chemicals to our water, the water is contaminated and the quality is impacted as the water has become degraded and has different impurities in it.Now, even though the water is clean, it will give you the benefits of such pollution. However, the degradation of the water makes the water stale and eventually, the taste of the water is not as good as before.That is why having a chemistry filter in your system is very important as such pollution can cause health problems. Many companies today, mainly large corporations, provide these filters for their staff as part of their work. As the demand for such filters increased, more companies started to advertise about their filters and the benefits of such filters in order to draw the attention of customers.What makes the water taste so bad if you have a filter installed in your water? One of the most common impurities that causes this taste in the water is heavy metals like mercury, lead, arsenic and others. There are studies and tests that prove that these heavy metals affect the human body. If the filters are not installed properly, then heavy metals can contaminate the whole water system.When you buy a filter, make sur e that it is placed properly in your system. It can be of different kinds, and they can be mechanical, electrical or chemical. The idea is to have all of them installed in your system so that all of the impurities get filtered out and the water tastes great.

Why Top Colleges Have Again Lowered Acceptance Rates

Why Top Colleges Have Again Lowered Acceptance Rates The nations elite colleges just became even more elite. Harvard, Stanford and Princeton some of the nations hardest colleges to get into boasted lower acceptance rates for the 2011 school year compared to 2010, according to an article in the Washington Post. These schools had record-breaking number of applicants for 2011 but only admitted the same number of students, creating a much lower acceptance rate. Most colleges have experienced a significant increase in the number of applications. Most colleges have even had record-breaking numbers in the past few years. This phenomenon is consistent across most colleges as the Internet and other resources have made it easier for students to apply to many colleges at the same time. Most colleges have reduced their acceptance rates because they know students are applying to several other schools and are therefore less likely to enroll if admitted. Colleges spend a lot of money and resources trying to recruit accepted students. So lowering the acceptance rate when more students apply is a quick and easy way to cut costs. However, most colleges like to keep their acceptance rate as low as possible. This becomes part of a colleges marketing. Colleges believe that a low acceptance rate is part of their allure and helps attract students, especially already-admitted students. Ivy League Colleges and other elite schools all compete with each other to boast lower acceptance rates. A college can then lobby to their admitted students, telling them that they are part of a very few number of students admitted, part of an elite group of incoming freshmen. This tactic can be very appealing and effective for elite schools recruiting programs. This tactic becomes much easier when colleges applications rise dramatically, which is why many schools encourage more students to apply. Students can expect this trend to continue, making colleges even more competitive, especially the nations most popular and elite colleges that garner a lot of interest and applications. Some highlights of admissions facts for the 2011 application year: Harvard dropped its admission rate for the 2011 school year to 6.2% from 6.9% in 2010. Overall, it admitted 2,158 students from a record applicant pool of 34,950. Princeton also decreased its acceptance rate to 8.4% from 8.8% last year. It admitted 2,282 students from a record 27,189 applicants. Stanford slightly decreased its admission rate to 7.1% from 7.2% last year. It admitted 2,427 students from a pool of 34,348, which is an increase from last year.

Sentence Fragments, Run-On Sentences, and a Comma Splices

Sentence Fragments, Run-On Sentences, and a Comma Splices   Punctuation errors are easy to make and hard to spot. For some writers, it is especially hard to catch punctuation errors such as sentence fragments, run-on sentences, and comma splices. These punctuation errors can really make your writing seem chaotic. A grammar checker can catch these errors some of the time. Better than a grammar checker is your ability to catch these errors yourself.   Sentence fragments A sentence fragment refers to groups of words that act like a sentence yet cannot stand on their own because the writer has made a range of mistakes. To start with, the right subject-verb relationship may not be available within the independent clause. For example, a statement such as Working Far into the Night with the Aim of Finding Their Ornament is a sentence fragment because the writer tries to describe something but fails to create a relationship between the subject and the verb. A different idea may also create a subordination of the relationship. It is worth noting that this can be acceptable when a writer is using it as a style in their pieces. The freedom is, however, restricted in professional writing. INCORRECT:   The sun shining. CORRECT:   The sun is shining.   Run-on sentences A run-on sentence is also known as a fused sentence. It has two independent clauses. The two parts are improperly connected. Even short sentences can be run-on sentences. In a nutshell, sentences are run-on sentences when two independent clauses are joined with a coordinator without a comma, or they are linked by a conjunctive adverb. This mistake is easily corrected with the right punctuation and conjunction.   INCORRECT:  Our house is narrow but it has 8 floors. CORRECT:   Our house is narrow, but it has 8 floors. EXPLANATION:   The conjunction but joins two sentences without a comma. Add a comma before the conjunction.   INCORRECT:   I asked everyone if they had seen my parrot but no one saw it. CORRECT:   I asked everyone if they had seen my parrot, but no one saw it.   Comma splice errors A comma splice is an error made by the writer when they use a comma to join two independent clauses. For instance, a sentence such as I am going to the library, I will study for my exam. In this case, the comma is utilized to join two independent clauses. It can be fixed by adding a conjunction. A semicolon can also be utilized because they are strong enough to create a relationship between two independent clauses. Furthermore, the writer may opt to write two different sentences and hence do away with the comma. In the artistic forms of writing such as poetry, the comma slices can be embraced to create an exciting piece. The racing thoughts of a character in a fictional story can be linked using the splices. In professional writing, however, this mistake must be avoided. INCORRECT:   I am going to the library, I will study for my exam. CORRECT:   I am going to the library. I will study for my exam. CORRECT:   I am going to the library, and I will study for my exam. It is clear that the run-on sentences, comma splices, and sentence fragments are different. However, they share a common characteristic; they tend to be utilized when a person is trying to create the appropriate independent clauses in a sentence. The writer may not be aware of how to create a subject and the verb properly, hence coming up with a sentence fragment. They may also be trying to create a connection between one thought to another, and will, therefore, make the mistake of including the run-on sentences and comma splices in a sentence. To avoid this, it is critical to observe the grammatical rules and regulations when writing. Proofreading the written materials is also worth considering.     Sources http://grammar.ccc.commnet.edu/grammar/fragments.htm http://www.chompchomp.com/terms/fragment.htm https://www.grammarly.com/blog/comma-splice/ https://www.grammarly.com/blog/run-on-sentence-basics/ http://grammar.ccc.commnet.edu/grammar/runons.htm Please follow and like us:
