Answer:
3.37kg of NaCl is the salt content of the dead sea
Explanation:
A concentration of 33.7% means there are 33.7g of NaCl in 100mL of solution.
To solve this question we need to convert 10.0L to mililiters, and then, solve for the mass of NaCl in grams and convert it to kg:
<em>Volume in milliliters:</em>
10.0L * (1000mL / 1L) = 10000mL
<em>Mass of NaCl:</em>
10000mL * (33.7g NaCl / 100mL) = 3370g NaCl
<em>In kg:</em>
3370g * (1kg / 1000g) =
<h3>3.37kg of NaCl is the salt content of the dead sea</h3>
Answer:
Water acutually has a higher boiling point because CO2 will turn into a gas form at a certain temp ( -78 C), so CO2 wouldn't really boil very long.
Hope this helps:)

Answer:</h3>
62.5 mL
<h3>
Explanation:</h3>
<u>We are given;</u>
- Molarity of the stock solution as 0.100 M
- Volume of the dilute solution as 250 mL
- Molarity of dilute solution as 0.0250 M
We are required to calculate the Volume of the stalk solution.
- Taking the volume and molarity of the stock solution to be V₁ and M₁ respectively, and volume and molarity of the dilute solution to be V₂ and M₂ respectively.
We are going to use the dilution formula;
- According to the dilution formula, M₁V₁ = M₂V₂
- Rearranging the formula;
V₁ = M₂V₂ ÷ M₁
= (0.025 M × 0.25 L) ÷ 0.100 M
= 0.0625 L
But, 1 L = 1000 mL
V₁ = 62.5 mL
Therefore, the volume of the stock solution is 62.5 mL
Answer:it is balanced
Explanation:
u can see that there is 1 ZN on both side, 2H on both side, 2Cl on both side, so it is balanced
