Question

part 1
are the following equations balanced? you do the math.....

1. 2na + cl₂ ---------> 2nacl yes

(2×23 + 35×2) —> 2(23 + 35)
46 + 70 2(58)
58 116 = 116

1. 2hg + o₂ ------------> 3hgo

(2) +

1. so₃ ---------> 2so₄ + o₂

Explanation:

Step1: Analyze Equation 2 (Hg and O)

Count Hg: Left = 2, Right = 3. Count O: Left = 2, Right = 3. Not equal.

Step2: Analyze Equation 3 (S and O)

Count S: Left = 1, Right = 2. Count O: Left = 3, Right = \(2\times4 + 2 = 10\). Not equal.

Step3: Confirm Equation 1

Equation 1: \(2\text{Na} + \text{Cl}_2
ightarrow 2\text{NaCl}\). Na: 2=2, Cl: 2=2. Balanced.

Answer:

1. Balanced (Yes), 2. Not Balanced, 3. Not Balanced
