Answer:
6.67 M
Explanation:
Molarity =
<em>Convert 200g NaOH to moles. Convert 750 mL to L.</em>
200 g NaOH x (1 mol/39.998 g) = 5.00025... mol NaOH
750 mL x (1 L/1000 mL) = 0.750 L
<em>Substitute values into the equation.</em>
Molarity =
Molarity = 6.667... M
Molarity = 6.67 M

A iron combines with oxygen to produce rust, which is the compound named iron
Answer:
Because it takes tremendous effort to break free from the laws of gravity to exit the Earth's atmosphere
Explanation:
Answer:
Option D is correct
Explanation:
The individual mass of reactants in the reaction are
Calcium Oxide (CaO) = amu
Carbon dioxide (CO2) amu
Since this reaction is a simple addition reaction in which no mass of the reactants is wasted. Also, no energy is released accompanied by conversion of mass into energy.
Hence, total mass of reactants would be equal to the mass of the product.
Thus, mass of calcium carbonate i.e CaCO3 is
amu
Hence, option D is correct
