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)
Answer:
12430mL of water must be added
Explanation:
To solve this question we need to convert the 20%w of CuSO₄ to molarity. Then, using the <em>diulution factor </em>we can find the amount of water required:
20g CuSO₄ / 100mL * (1mol / 159.609g CuSO₄) = 0.1253 moles / 100mL = 0.1253mol / 0.1L =
1.25M is the concentration of CuSO₄. To dilute this concentration to 0.01M, the dilution factor must be of:
1.25M / 0.01M = 125 times must be diluted the solution.
As the volume of the concentrated solution is 100mL, the total volume of the solution to have a 0.01M solution must be of:
100mL * 125 times = 12530mL is the final volume of the solution. That means the amount of water added must be of:
12530mL - 100mL =
<h3>12430mL of water must be added</h3>
Answer:
D
Explanation:
The answer should be that the solution is unsaturated
Answer:
Base
Explanation:
Why is Alka-Seltzer a base?
Alka-Seltzer contains sodium bicarbonate and citric acid. The sodium citrate acts as an antacid. Excess sodium bicarbonate from the Alka-Seltzer acts to neutralize base.
An inert gas will not react with either the reactants or the products, so it will have no effect on the product/reactant ratio, and therefore, it will have no effect on equilibrium.
