2Mg + O2 yields 2MgO
Mg + 2HCl yields MgCl2 + H2
Answer:
Explanation:
1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example:
2. Double displacement reaction is one in which exchange of ions take place.
Example:
3. Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Example:
False
The volume of one mole of gas at STP is 22.4 liters.
In the combustion reaction of acetylene (C2H2), 60 liters of CO2 will be produced if 60 liters of O2 is used.
To determine the volume of CO2 produced in the combustion reaction of acetylene (C2H2), we need to use stoichiometry. From the balanced equation, we can see that 2 moles of C2H2 produce 4 moles of CO2. The ratio is 2:4 or 1:2. Given that 60 liters of O2 is used, we can assume the same volume of CO2 will be produced since both gases are at STP.
Therefore, the volume of CO2 produced would be 60 liters as well.
