Answer:
True
Explanation:
They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone, making them the simplest out there
Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.
Explanation:
To calculate the moles :


According to stoichiometry :
1 mole of
require = 2 moles of 
Thus 0.06 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 1 moles of
give = 1 mole of 
Thus 0.06 moles of
give =
of 
Mass of 
Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.
