Answer:
2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.
Explanation:
- The potassium sulfide has the chemical formula <em>K₂S.</em>
∴ Every 1.0 molecule of K₂S composed of 2.0 atom of K and 1.0 atoms of S.
<u><em>So, 2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.</em></u>
C is the answer I took a test with the same answer
Answer: Selection proper
Explanation:
it's an anti-chance process, but subject to many constraints
<h3><u>Answer;</u></h3>
Directly proportional
<h3><u>Explanation;</u></h3>
- <em><u>Concentration is one of the factors that determine the rate of a reaction. Reaction rates increases with increase in the concentration of the reactants, which means they are directly proportional.</u></em>
- An increase in the concentration of reactants produces more collisions and thus increasing the rate at which the reaction is taking place. Therefore, <u>Increasing the concentration of a reactant increases the frequency of collisions between reactants and will cause an increase in the rate of reaction.</u>
Answer:
False
Explanation:
Wild animals are found in an ecosystem and they are considered to be a natural resource and a biotic factor in the environment. They are living things so they are a natural resource.
