Answer:
Na₂SO₄
Explanation:
Barium nitrate, Ba(NO₃)₂ produce precipitate with SO₄²⁻, CO₃²⁻. That means the precipitate could be obtained from Na₂SO₄ and Na₂CO₃.
Also, magnesium nitrate, Mg(NO₃)₂, produce precipitate just with CO₃²⁻. As the unknown solution produce no precipitate, the unknown compound is:
<em>Na₂SO₄</em>

“If a certain metal is cooked, it will conduct electricity better”
- this is a hypothesis, since the statement is kind of vague...”certain metal”...and is written in an “if-then” format.
The amount of electric current that passes through a conductor is directly proportional to the voltage and is described as V = IR
- laws are usually scientific understanding that we’ve tested so much that we’ve come to a conclusion that can often be written out as a mathematical relationship. Hence, the “V = IR”
Electricity is the flow of electric charge in the form of electrons moving through a circuit
- this is a theory. I would give an explanation but I’m out of time.
Hope this helps

Answer:
<h2>4. dominant negative</h2>
Explanation:
Mutation is the process in which sudden changes take place within the sequence of amino acids that causes different type of problems. On the basis of nature and conditions mutation can be classified as dominant negative, neomorphic and some others types. Dominant mutation is also called as antimorphic mutation and changes the functions of the molecules that are proteins.
