Answer:
B. Rocks can be formed and altered by the activity of organisms
Explanation:
Answer:
<h2>YES</h2>
Explanation:
Coyotes and oak trees are multicellular organisms and multicellular organisms reproduce asexually and sexually.
Many multicellular lower plants give off asexual spores, either aerial or motile and aquatic (zoospores), which may be uninucleate or multinucleate.
The reactant in a chemical process known as the limiting reactant controls how much product can be produced. When the limiting reactant is completely used up, the reaction will come to an end.

Find the limiting reactant ?</h3>
- As a result of 1 mol Sb4O6 reacting with 6 mol H2SO4, only 0.1 mol Sb4O6 reacts with 0.6 mol H2SO4, leaving only 0.5 mol H2SO4. This indicates that H2SO4 is the limiting reactant and Sb4O6 is present in excess.
- According to your equation, which is balanced, 0.1 mol Sb4O6 should react with 0.6 mol H2SO4, yet there is only 0.5 mol H2SO4 on hand.
- Therefore, only.083 mol of Sb4O6 are reacted.
- The reactant that is present in the limiting amount—the limiting reactant—determines the extent to which a chemical reaction occurs.
- The trick is really quite easy! We employ an augmented matrix to hold the data derived from the balancing equation Sb4O6 + 6H2SO4 --> 2Sb2(SO4)3 + 6H2O.
- Although you are provided 0.5 mol of H2SO4, the reaction requires 0.6 mol. Therefore, the limiting reactant is H2SO4.
- Only 0.0833 mol of Sb4O6 is required, but you have 0.1 mol. Sb4O6 is therefore the extra reactant.

Answer:
Option D (
)
Explanation:
Acids react with metal to form salt and hydrogen gas.
Metals which are more reactive than hydrogen evolve hydrogen gas on reaction with acid.
For example:
Magnesium reacts with hydrogen chloride to form magnesium chloride and hydrogen.
2HCl(aq) + Mg(s) → MgCl2(aq) + H2(g)
Al and Zn are more reactive than hydrogen, therefore, these metals evolve hydrogen gas on reaction with acid.
reacts with HCl to form NaCl and nitric oxide.
reacts with HCl to form potassium chloride, carbon dioxide and water.
As reaction of does not evolve any gas, therefore, the correct option is D.
