Answer:
The correct option is: 2.50 g
Explanation:
Reaction involved: Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g)
Molar mass: Mg = 24.305 g/mol, HCl = 36.461 g/mol
In the given reaction, 1 mole Mg reacts with 2 moles HCl.
Given: mass of HCl = 7.50 g
So, the number of moles of HCl = given mass ÷ molar mass = 7.50 g ÷ 36.461 g/mol = 0.2057 moles
Therefore, the<u> number of moles of Mg</u> that reacts with 0.2057 mole HCl = 0.2057 ÷ 2 = 0.1028 moles
Therefore, <u>the mass of Mg in grams</u> = molar mass × number of moles = 24.305 g/mol × 0.1028 mole = 2.5 g
Answer:
Genes are segments of DNA that are located on the chromosomes of each cell.
Explanation:
Chromosomes are basically tightly bundled thingies containing genes, DNA, whatever. Phenotype and genotype have nothing to do with chromosomes, that's just how WE describe them.

Charlemagne has been called the "Father of Europe" (Pater Europae), as he united most of Western Europe for the first time since the classical era of the Roman Empire and united parts of Europe that had never been under Frankish or Roman rule.
Explanation:
<u>Answer:</u> 
is an acid, 
is a base, 
is conjugate base and 
is conjugate acid
<u>Explanation:</u>
According to Bronsted and Lowry's theory:
An acid is defined as a proton donor while a base is defined as a proton acceptor.
In a chemical reaction, an acid loses a proton to form a conjugate base while a base accepts a proton to form conjugate acid.
For the given chemical reaction:
is losing a proton thus it is an acid to form which is its conjugate base
is gaining a proton thus it is a base to form which is its conjugate acid
Hence, is an acid, is a base, is conjugate base and is conjugate acid
