This should help you with your problem
The metal could make an excellent material for cookware because it has a low specific heat. Specific heat is defined as the amount of energy required to raise the temperature of a body per unit mass. A low specific heat means less energy is required to get the cookware hot. In cookware the actual cooking part is designed to have low specific heat and the handles made to have high specific heat. The high specific heat at the handles ensures safety since it would take more time for the handles to get hot.
Volume of NaOH required to react = 145.5 ml
<h3>Further explanation</h3>
Reaction
CO₂(g)
+ 2 NaOH(aq) ⇒Na₂CO₃(aq) + H₂O(l)
The volume of CO₂ : 0.45 L
mol CO₂ at STP (O C, 1 atm) ⇒ at STP 1 mol gas 22.4 L :

From the equation, the mol ratio of CO₂ : NaOH = 1 : 2, so mol NaOH :

Then volume of NaOH :

A element mixture (key word: mixture) due to the mixture containing 2 different types of elements it can be said that it’s highly likely that the mixture was not a compound but instead of a mixture due to mixture meaning more than 1 material. Hopes this help!
Answer:
The answer to your question is 0.3 moles of NaCl
Explanation:
Data
NaCl = ?
Al(NO₃)₃ = 0.1 moles
Balanced reaction
Al(NO₃)₃ + 3NaCl ⇒ 3NaNO₃ + AlCl₃
Now, use proportions to solve the problem
1 mol of Al(NO₃)₃ ------------ 3 moles of NaCl
0.1 moles of Al(NO₃)₃ -------- x
x = (0.1 x 3) / 1
x = 0.3 moles of NaCl
