1. Factorise<br>3х<br>- 10x +8​
lara [203]

Answer:

This question is incomplete, it should read 3x² - 10x + 8. The answer is (3x-4) (x-2).

Please find the solved explanation to this question attached

Explanation:

To factorize means to write an expression as a product of its factors using brackets. It is the opposite of expanding an algebraic expression i.e. it involves contracting it using factors common to the variables.

In this question, 3x² - 10x + 8 is given

For the sum, which is -10x, and product, which is 24x², -6x and -4x are the two variables whose sum will give rise to -10x and also whose product will give rise to 24x².

We have;

3x² - 10x + 8

3x² - 6x - 4x + 8

Next, we look for factors of each pair of expression.

3x (x - 2) - 4 (x - 2)

(3x - 4) (x - 2)

1) The heat of combustion for the gases hydrogen, methane and ethane are −285.8, −890.4 and −1559.9 kJ/mol respectively at 298K.
Morgarella [4.7K]

Answer:

The enthalpy of the reaction is 64.9 kJ/mol.

Explanation:

H_2 + \frac{1}{2}O_2\rightarrow H_2O,\Delta H_1 =-285.8 kJ..[1]

CH_4 + 2O_2\rightarrow CO_2 + 2H_2O,\Delta H_2 =-890.4 kJ..[2]

C_2H_6 + \frac{7}{2}O_2\rightarrow 2CO_2 + 3H_2O,\Delta H_3= -1559.9 kJ..[3]

2CH_4(g)\rightarrow C_2H_6(g) + H_2(g),\Delta H_4=?..[4]

2 × [2] - [1]- [3] = [4]  (Using Hess's law)

\Delta H_4=2\times \Delta H_2 -\Delta H_1 -\Delta H_3

\Delta H_4=2\times (-890.4 kJ)-(-285.8 kJ) -(-1559.9 kJ)

\Delta H_4=64.9 kJ/mol

The enthalpy of the reaction is 64.9 kJ/mol.
