Answer:
4-methyl-1-pentyne or 4-methylpent-1-yne
Explanation:
presence of triple bond(alkyne)
Answer:
letter A.
Explanation:
the rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. this is done by cutting the substance into small pieces, or by grinding it into a powder.if the surface area of a reactant is inceased: more particles are exposed to the other reactant.

33060 grams of magnesium nitrate would be produced from with 3.421 X 10²⁶ formula units of magnesium hydroxide.
<h3>HOW TO CALCULATE MASS?</h3>
The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.
However, the number of moles of magnesium hydroxide must be calculated by dividing the formula units by Avogadro's number.
no. of moles = 3.421 X 10²⁶ ÷ 6.02 × 10²³
no. of moles = 0.57 × 10³
no. of moles = 5.7 × 10²moles
Molar mass of Mg(OH)2 = 24 + 34 = 58g/mol
mass of Mg(OH)2 = 570 moles × 58g/mol
mass of Mg(OH)2 = 33060g
Therefore, 33060 grams of magnesium nitrate would be produced from with 3.421 X 10²⁶ formula units of magnesium hydroxide.
