Answer:
The answer to your question is Volume = 600 ml
Explanation:
Data
Volume 1 = 810 ml
Temperature 1 = 270°K
Pressure 1 = 1 atm
Volume 2 = ?
Pressure = 2 atm
Temperature 2 = 400°K
Process
1.- To solve this problem, use the Combine gas law.
P1V1 / T1 = P2V2 / T2
- Solve for V2
V2 = P1V1T2 / T1P2
2.- Substitution
V2 = (1)(810)(400) / (270)(2)
3.- Simplification
V2 = 324000 / 540
4.- Result
V2 = 600 ml
<h3>
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:
Ductility
Explanation:
Ductility is the ability of a metal to be converted into a thin wire without getting break and loosing its hardness. The property of Ductility of a metal allows us to make a wider use of them. Some most ductile metals are gold, silver, copper etc. whereas some of the metals with very less ductility are tungsten, steel and other alloys as they are very hard to transform into a thin wire.
A metal with less ductility can be malleable as it can have the ability to be converted into a thin sheet. Not all the metals are ductile but some of them have high ductility, some have less and some of them are non ductile.
Answer:
The increase in mass is because the iron fillings have combined with a sulfide to produce iron sulfide and so the mass will increase.
In such a reaction like this, the mass of the reactants must be conserved. By so doing, the mass of reactants and products must be the same.
When two substances combine together, their masses added up to that of the individual masses. This helps to conserve the mass.
