There are 3 possible mole ratios
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
<em>N₂(g)+3H₂(g)⇒2NH₃</em>
So mol ratio :
N₂:H₂:NH₃=1:3:2
1 mole N₂
3 mol H₂
2 mole NH₃
3 mole H₂
1 mole N₂
2 mole NH₃

Answer:
I think it's C or D Sorry if I'm Wrong
Explanation:
it just makes the most sense to me
So half life is the time taken for a sample to decay to half its original mass, its a constant and applies to any original mass, it could be 5g or 1kg, it will take the same amount of time for the original mass to half. In this case the half life is 3 days.
After 3 days the sample will be at half its original mass, now 50g.
Now we can treat the 50g as if its a new sample. After another 3 days (6 days in total) there will be half of 50g left, = 25g.
Answer:
chemical
Explanation:
Chemical weathering, which is the decomposition of a rock by the alteration of its chemical composition.
Answer:
D - Hydroxide Ion (OH-)
Explanation:
A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.
