<span>no.of moles of SF6 = 0.35/molar mass of SF6 = 0.35/146.06 = 2.396 X 10^-3 </span>
<span>so you need 2.396 X 10^-3 moles of NH3 molecules </span>
<span>molar mass of NH3 = 17.031 g/mole </span>
<span>that means 1 mole of NH3 = 17.031 g </span>
<span>so 2.396 X 10^-3 moles of NH3 = 17.031 X 2.396 X 10^-3 = 0.041 g</span>
Answer:
6+9=15
mass number =15
mass number = no. protons + no. of neutrons
It would be a human egg cell. Microbiologists study microscopic organisms that cause infections, including viruses, bacteria, and fungi+algae
Answer:
The cohesive forces between the water molecules are very strong making the surface tension of water high. As surfactants absorb they break these interactions. The intermolecular forces between surfactant and water molecule are much lower than between two water molecules and thus surface tension will decrease

Answer:
A. The reactants are changed to form the products.
Explanation:
Chemical reactions are reactions that involves a change in the chemical composition of substances involved while a nuclear reaction is the process of fusing together or splitting the nucleus of an atom. According to this question, matter is said to undergo both types of reaction.
However, one similarity in both chemical and nuclear reactions is that substances called REACTANTS are changed to form PRODUCTS. In nuclear reaction, the atoms joined or split are the reactants while the ones formed are the products.
