Answer:
The correct answer is - 66g.
Explanation:
Given:
molecules of CO2 = 9.03 x 10^23
We know:
1 mole of any substance = 6.02x10^23 molecules. (Avogadro's number)
M (CO2) = 12 + (2x16) = 12 + 32 = 44g
Solution:
The mass of CO2 with 9.03x10^23 molecules would be:
44g of CO2 = 6.02x10^23 molecules.
So, the mass in grams of CO2 (X) = 9.03x10^23 molecules
Xg of CO2 = (44x9.03x10^23)/6.02x10^23 = 66g
Thus, the correct answer would be - 66gm.
Answer:
Combination or synthesis reaction
Explanation:
The reaction is a combination or synthesis reaction.
Let us write the reaction equation:
CO + H₂O → H₂CO₃
A combination or synthesis reaction is one in which a single product forms from two or more reactants. The formation of a compounds from the union of their constituent elements falls into this category of reaction.
- The combination of carbon monoxide and water to give hydrogen carbonate is one of such reaction.
Answer:
OD. 2HCl
Explanation:
A balanced equation needs the equal # of each element on BOTH sides.
By putting a 2 in front of HCl you now have 2 hydrogens on both sides and 2 chlorines. The Ca and CO3 are already balanced.
