a. For the reaction 2H2 + 02→ 2H20, how many moles of water can be produced from 6.0 mol of oxygen? 2.0 mol b. 6.0 mol 12 mol d.

pickupchik [31]

Explanation:

from the equation 1 mole of O2 will give 2 moles of H2O then 6.0 moles of O2 will give x

6.0*2 moles/ 1 mole

= 12 moles

this implies that, 6.0 moles of O2 will give = 12 moles of water

Balance this equation and pick the answer with the coefficients that belong there.

geniusboy [140]

Answer:

2,3,6,1

Explanation:

The unbalanced reaction expression is given as:

AlBr₃ + K₂SO₄ → KBr + Al₂(SO₄)₃

We need to balanced this reaction equation. Our approach is a mathematical method where we assign variable a,b,c and d as the coefficients.

aAlBr₃ + bK₂SO₄ → cKBr + dAl₂(SO₄)₃

Conserving Al; a = 2d

Br: 3a = c

K: 2b = c

S: b = 3d

O: 4b = 12d

Let a = 1, c = 3, d = $\frac{1}{2}$ b = $\frac{3}{2}$

Multiply through by 2 to give;

a = 2, b = 3, c = 6 and d = 1

2AlBr₃ + 3K₂SO₄ → 6KBr + Al₂(SO₄)₃

When an ionic compound dissolves in water:_________.

Katarina [22]

Answer:

a. the negative ends of water molecules surround the positive ions.

Explanation:

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

Thus,

$NaCl_{(s)}\rightarrow Na^+_{(aq)}+Cl^-_{(aq)}$

When the ionic compound dissociates, the cation which is positively charged gets attracted to the oxygen (Negative ends) which is present in the water. The anion which is negatively charged gets attracted to the hydrogen (Positive ends) of the water.

Hence, the correct option is:- a. the negative ends of water molecules surround the positive ions.
