Answer:
Chemical that can be mixed with another chemical to reduce the dangerous of a specific chemichal
HCl is <span>limiting reactant, Mg in excess therefore:
</span><span>number of moles HCl:
75.0 mL in liters: 75.0 / 1000 => 0.075 L
Molarity HCl = 1.0 M
n = M x V
n = 1.0 x 0.075
n = 0.075 moles of HCl
</span>Mg(s) + 2 HCl (aq) = H2 (g) + MgCl2 (aq)
<span>2 moles HCl -------------------- 1 mole H2
</span><span>0.075 moles of HCl ------------ ( moles H2)
</span>
moles H2 = 0.075 x 1 / 2
moles H2 = 0.075 / 2
= 0.0375 moles of H2
hope this helps!

Answer:
The correct answer is option C.
Explanation:
Single replacement reaction : It is a type of chemical reaction in which element exchange their position with the position of another element in its compound molecule.

It is also called redox reaction because one element getting oxidized and another one getting reduced.
Hence, the correct answer is option C.
Explanation:
The total inches of rainfall....etc.
