Mg (magnesium) reacts with acids and Produces magnesium salt and hydrogen gas as the products.
Followings are some balanced reactions of Mg with acids.
Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g)
Mg(s) + 2HNO₃(aq) → Mg(NO₃)₂(aq) + H₂(g)
The question is incomplete. The image showing the compound and the options in the questions is attached.
Answer:
B
Explanation:
If we closely examine the structure of the compound given in the question, we will notice that the reaction must involve the substitution of the hydroxyl group by chlorine in the parent molecule.
This occurs when the -OH group combines with H^+ to form -OH2^+ which is a good leaving group.
Compound B is formed because, when -OH2^+ leaves, a carbocation is created. This carbocation is stabilized by the alkyl groups attached to the carbon atom bearing the leaving group by +I inductive effect. This carbon atom bearing the leaving group is a tertiary carbon atom thus it forms a more stable carbocation. Hence the product formed.
Answer:
The number of mole is 0.04167mole
Explanation:
To convert gram to mole, we need to calculate the molecular weight of the compound
C6H12O6
C - 12
H - 1
O - 16
Molecular weight = 6 * 12 + 1 *12 + 6 * 16
= 72 + 12 + 96
= 180g/mol
To covert gram to mole
Therefore,
= 7.50g/ 180g/mol
= 0.04167 mole of glucose
The answer for question 14 would be C and question 15 is B
Explanation:
Standardization is the process of creating protocols to guide the creation of a good or service based on the consensus of all the relevant parties in the industry. ... Standardization also helps in ensuring the safety, interoperability, and compatibility of goods produced.
