The mass of the acid produced is 0.252 g from the information in the question.
<h3>What is neutralization?</h3>
The term neutralization refers to the reaction between an acid and a base that yileds salt and water only.
The equation of this reaction is; 2HCl + CaCO3 ----->CaCl2 + CO2 + H2O
Number of moles of CaCO3 = 0.350 g/100 g = 0.0035 moles
Since 2 moles of acid reacts with 1 mole of CaCO3
x moles acid reacts with 0.0035 moles of CaCO3
x = 0.007 moles
Mass of acid = 0.007 moles * 36 g/mol = 0.252 g

If we draw the lewis structure, we can see that all Cl
atoms are all connected to the B atom. Now Cl atoms has 7 electrons each on its
outermost shell while B can donate 3 electrons. So by octet rule, each Cl will
gain 1 electron each from the B atom. From the Lewis structure, we can see that
there are actually No Lone pairs on the central atom.

In a chemical reaction, the atoms of the starting species called reactants rearrange to form new substances which are the products of the chemical reaction. The identities of the atoms involved in the reaction remain the same. Their number also stays the same before and after the reaction
Answer:
Explanation:
Chemical equation:
Fe + Cl₂ → FeCl₃
Balanced chemical equation:
2Fe + 3Cl₂ → 2FeCl₃
Chemical equation:
H₂O₂ → H₂O + O₂
Balanced chemical equation:
2H₂O₂ → 2H₂O + O₂
Chemical equation:
Ca + O → CaO
Balanced chemical equation:
Ca + O → CaO
Chemical equation:
Al + O₂ → Al₂O₃
Balanced chemical equation:
4Al + 3O₂ → 2Al₂O₃
Answer:
See explanation
Explanation:
A drying tube prevents moisture from contaminating the reactants. The drying tube contains CaCl2 a hygroscopic material whose function is to absorb the moisture so that it does not react with the Grignard reagent. Without the desiccating action of CaCl2, moisture will enter the reaction chamber,contaminating the reactants.
If water reacts with the Grignard reagent, an alkane is formed. The mechanism of this reaction is shown in the image attached. R here represents the alkyl moiety of the Grignard reagent.
