Answer: Option (B) is the correct answer.
Explanation:
Marble is also known as calcium carbonate and its chemical formula is .
When it combines with vinegar then it results in the formation of calcium acetate which is a water soluble compound along with the release of carbon dioxide which occurs in the form of bubbles and water.
The reaction is as follows.
Whereas vinegar being a weak acid will not react with glass, copper and steel.
I believe its a covalent bond?
Lithosphere
Explanation:
solid portion of the Earth
Answer: Synthesis
0.84 moles of oxygen
25 moles of
Explanation:
The balanced chemical equation is:
This is a synthesis reaction as one product is formed by combination of two reactants.
According to stoichiometry :
a. 2 moles of require = 3 moles of
Thus 0.56 moles of require= of
b. 4 moles of give = 2 moles of
Thus 50 moles of give = of
