Answer:
SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of ammonium sulfate and barium nitrate are mixed.
(NH₄)₂SO₄(aq) + Ba(NO₃)₂(aq) ⇒ BaSO₄(s) + 2 NH₄NO₃(aq)
The complete ionic equation includes all the ions and insoluble species.
2 NH₄⁺(aq) + SO₄²⁻(aq) + Ba²⁺(aq) + 2 NO₃⁻(aq) ⇒ BaSO₄(s) + 2 NH₄⁺(aq) + 2 NO₃⁻(aq)
The net ionic equation includes only the ions that participate in the reaction and the insoluble species.
SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)
Answer:
There is <u>only one change</u> when transcribing from a DNA sequence to a RNA sequence.
Explanation:
The change when transcribing is that instead of thymine (T) in a DNA sequence, you have Uracil (U) in a RNA sequence. The rest will stay the same. So, <u>DNA has ATCG</u>, whereas <u>RNA has UACG</u>. There should be <u>NO thymine (T)</u> in your RNA sequence–– it should only include the four of the following: UACG.
[FORMAT]: DNA is to RNA
<u>A is to U</u> (IMPORTANT, NO "T") –– Think as <u>Apples Under</u> the Tree
<u>T is to A</u> –– Think as <u>Trees have Apples</u>
<u>C is to G</u> –– Think as <u>Car in the Garage </u>
<u>G is to C</u> –– Think as <u>Inside the Garage are Cars</u>
When you are doing a experiment, you are testing if your hypothesis is correct or false. If your hypothesis is false, you have to disgard it. If it is correct, you have to do many more parallels, and if they also confirm your hypothesis, your hypothesis can become a theory.
