Answer:
1.43*10 to the power of -10
Explanation:
Since 1.43*10 to the power of -10 is nothing else but
1.43/10¹⁰ which is equal to the number in the question
It is not 10¹⁰ because it will increase the number of zeros to the right
but we need to increase it towards the left
Hope this helps
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
Explanation:
The balanced chemical reaction between copper (II) oxide and carbon monoxide is producing cooper and carbon dioxide:
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
where:
(s) - solid
(g) - gas
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.

Answer:
If your lab has litmus paper, you can use it to determine your solution's pH. When you place a drop of a solution on the litmus paper, the paper changes color based on the pH of the solution. Once the color changes, you can compare it to the color chart on the paper's package to find the pH.
Explanation:
A solution's pH will be a number between 0 and 14. A solution with a pH of 7 is classified as neutral. If the pH is lower than 7, the solution is acidic. When pH is higher than 7, the solution is basic. These numbers describe the concentration of hydrogen ions in the solution and increase on a negative logarithmic scale.
For example, If Solution A has a pH of 3 and Solution B has a pH of 1, then Solution B has 100 times as many hydrogen ions than A and is therefore 100 times more acidic.
