Answer:

D

Explanation:

Mg(OH)2(s) + HCl(aq) →H2O(l) + MgCl2(aq)

Left Side

Mg = 1

O = 2

H = 3

Cl = 1

Right Side

Mg = 1

O = 1

H = 2

Cl = 2

Mg(OH)2(s) + 2HCl(aq) →2H2O(l) + MgCl2(aq)

Left Side

Mg = 1

O = 2

H = 4

Cl = 2

Right Side

Mg = 1

O = 2

H = 4

Cl = 2

D) 1, 2, 2, 1

As we can see the chemical equation is balanced.K3PO4 + Al(NO3)3 → 3KNO3 + AlPO4 

So, by principle of conservation of mass when 1 mole of K3PO4 reacts with 1 mol of Al(NO3)3 , it peoduces 3 mol of KNO3 and 1 mol of AlPO4

So, when 2.5 moles of potassium phosphate react and Al(NO3)3 is present in excess , 2.5*3= 7.5 mol of KNO3 is formed

Classify the following substituents according to whether they are electron donors or electron acceptors relative to hydrogen by
igor_vitrenko [27]

Species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

<h3>What is resonance?</h3>

The term resonace has to do with the movement of electron pairs in a molecule. Inductive effects has to do with the drawing of electron density towards an atom or bond.

The two effects depends on the nature of a substituent. For instance, species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

The question is incomplete hence the exact nature of the substituents can not be determined.
