If you're indoors, stay inside. If you're outside, stay outside. If you're indoors, stand against a wall near the center of the building, stand in a doorway, or crawl under heavy furniture (a desk or table). Stay away from windows and outside doors.
The question does not provide the equation
Answer:-
72.89 grams
Explanation:-
The balanced chemical equation for this reaction is
CuSO4 + Fe --> FeSO4 + Cu
Molecular weight of CuSO4 = 63.55 x 1 + 32 x 1 + 16 x 4
= 159.55 gram
Atomic weight of Cu = 63.55 gram.
According to the balanced chemical equation
1 CuSO4 gives 1 Cu
∴159.55 gram of CuSO4 would give 63.55 gram of Cu.
183 gram of CuSO4 would give 63.55 x 183 / 159.55
= 72.89 grams of Cu
Between 90 and 95 degrees Farenheit
The concentration of hydronium ion, [H₃O⁺] = 1.3 × 10⁻⁶ M
<u>Explanation:</u>
HClO is a weak acid and it can be ionized and given by the equation as,
HClO + H₂O ⇄ H₃O⁺ + ClO⁻
Ka is given by the expression that the product of the concentration of products divided by the product of the concentration of the reactants.
![$ Ka = \frac{[H_{3} O^{+}]\times [ClO^{-} ]}{[HClO]}](https://tex.z-dn.net/?f=%24%20Ka%20%3D%20%5Cfrac%7B%5BH_%7B3%7D%20O%5E%7B%2B%7D%5D%5Ctimes%20%5BClO%5E%7B-%7D%20%20%5D%7D%7B%5BHClO%5D%7D)
= 2.9 ×10⁻⁸
Consider [H₃O⁺] = [ClO⁻] = x
[HClO] = 0.365 - x
Since Ka is very small, consider x <<<0.365, also it should be ignored.
Ka = 2.9 ×10⁻⁸ = 
x² = 2.9 × 10⁻⁸ × 0.365
x = 1.3 × 10⁻⁶ M
Thus we can conclude 3rd Option as correct answer
