Answer:

X = 350 kJ/mol

Explanation:

According to the question:

Energy needed when breaking bonds + 1640 kJ/mol = Energy released when forming bonds

∴ 2 (C - C) + 8 (C - H) + 5 (O = O) + 1640 = 6(C = O) + 8(O - H)

⇒ 2 (X) + 8 (410) + 5 (500) + 1640 = 6 (740) + 8 (460)

⇒ 2X + 7420 = 8120

⇒ 2X = 700

⇒ X = 350 kJ/mol

alisha [4.7K]

Answer:

$7.589\times 10^{2}$

Explanation:

The expression can be solved mathematically as follows:

1) $8.310\times 10^{2}-7.210\times 10^{1}$ Given

2) $8.310\times 10^{1+1} - 7.210\times 10^{1}$ Definition of sum

3) $(8.310\times 10^{1})\times 10^{1}-7.210\times 10^{1}$ $a^{m+n} = a^{m}\cdot a^{n}$ /Associative property

4) $(8.310\times 10^{1}-7.210)\times 10^{1}$ Distributive property

5) $(83.100-7.210)\times 10^{1}$ Multiplication

6) $75.89\times 10^{1}$ Subtraction.

7) $(7.589\times 10^{1})\times 10^{1}$ Multiplication/Associative property

8) $7.589\times (10^{1}\times 10^{1})$ Associative property

9) $7.589\times 10^{2}$ $a^{m+n} = a^{m}\cdot a^{n}$ /Result
