Answer:
<u>390g</u>
Explanation:
it's moles actually...
Molar mas of CaF2 is =78g/mol
It means 78g per mole...Si If you have 5 moles..that means you have...
78*5g of CaF2...
C. Magma is injected into surrounding rock forming an igneous intrusive
If it takes 35.04ml of a 0.2455M NaOH solution to neutralize 25. 00ml of an unknown HCl solution, the molarity of the HCl solution is 0.34M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = molarity of acid
- C2 = molarity of base
- V1 = volume of acid
- V2 = volume of base
According to this question, it takes 35. 04ml of a 0. 2455M NaOH solution to neutralize 25.00ml of an unknown HCl solution. The molarity of the HCl can be calculated as follows:
35.04 × 0.2455 = 25.0 × V2
8.602 = 25C2
C2 = 8.6/25
C2 = 0.34M
As a result, the molarity of the HCl solution is 0.34M if it takes 35. 04ml of a 0.2455M NaOH solution to neutralize 25ml of an unknown HCl solution.

Single displacement reaction
ZnCl₂ and H₂
Explanation:
The reaction is a single displacement reaction in which one specie replaces another in solution.
The driving force of this kind of reaction is the position of the elements in the activity series of elements.
- The activity series of elements shows how reactive metals are.
- Elements high in the series are highly reactive and will displace any one below them in solution.
- In the activity series, Zinc is higher compared to hydrogen.
- Zinc will displace the hydrogen form of ZnCl₂ and H₂
