A is the answer because the others don't make sense. B if you put glass over reactants it doesn't change anything in the reaction. C using a solid with a low surface area will actually be doing the opposite, a higher SA will increase the rate of reaction. D decreasing the concentration will decrease the reaction
<span>The reaction leads to carbon dioxide gas.
</span><span>It releases CO2 bubbles and leftover of sodium nitrate solution.</span>
Answer:
Molar mass = 99 g/mol
Explanation:
Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2
The molar mass is given as the sum off the individual atomic mass of the elements in the compound.
Molar mass = C + O + 2Cl
Molar mass = 12 + 16 + 2(35.5)
Molar mass = 99 g/mol
