Eh I guess it was okay what about you
Answer:
6.28x10⁻³ g
Explanation:
First we convert 0.1102 grams of CoHg(SCN)₄ into moles, using its <em>molar mass</em>:
- 0.1102 g ÷ 491.9 g/mol = 2.24x10⁻⁴ mol CoHg(SCN)₄
There is 1 Co mol per CoHg(SCN)₄ mol, meaning there's also 2.24x10⁻⁴ moles of Co.
We now <u>convert 2.24x10⁻⁴ moles of Co into grams</u>, using its <em>molar mass</em>:
- 2.24x10⁻⁴ mol Co * 28.01 g/mol = 6.28x10⁻³ g
Answer is: product of reaction.
<span>There are two types
of reaction: endothermic reaction (chemical reaction that absorbs more
energy than it releases) and exothermic reaction (chemical reaction that
releases more energy than it absorbs).
</span><span>According to
Le Chatelier's principle when the reaction is exothermic heat is
included as a product.</span>
For the titration we use the equation,
M₁V₁ = M₂V₂
where M is molarity and V is volume. Substituting the known values,
(0.15 M)(43.2 mL) = (2)(M₂)(20.5 mL)
We multiply the right term by 2 because of the number of H+ in H2SO4. Calculating for M₂ will give us 0.158 M. Thus, the answer is approximately 0.16M.
