Explanation:
nuclear fusion yields more energy than nuclear fission and the products of the reaction are not radioactive
Answer:
Inference
Explanation:
A conclusion reached on the basis of evidence and reasoning is called an inference.
Answer:
Option d. is correct
Explanation:
Nitromethane is an organic compound that can be used as a fuel booster in rockets. Its chemical formula is 
.
This compound is produced as a result of reaction of sodium chloroacetate with sodium nitrite in aqueous solution.
The electron-dot structure of a nitromethane molecule shows 
charge on the nitrogen.
Option d. is correct
Answer:
The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
Explanation:
The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
An example is H2SO4, also called sulfuric acid
It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2
X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4
