Answer:
The answer to your question is V2 = 3.7 L
Explanation:
Data
Volume 1 = 3.5 L
Temperature 1 = 25°C
Temperature 2 = 40°C
Pressure = cte.
Volume 2 = ?
Formula
To solve this problem use the Charles' law
V1/T1 = V2/T2
- Solve for V2
V2 = V1T2 / T1
- Convert temperature to °K
Temperature 1 = 25 + 273 = 298°K
Temperature 2 = 40 + 273 = 313°K
- Substitution
V2 = (3.5)(313) / 298
- Simplification
V2 = 1095.5 / 298
- Result
V2 = 3.7 L
Answer:
The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.
Explanation:
I dont know if this is right but i think the answer is 10.8 kilometers
Answer:
4.22 × 10 ⁻²² mol
Explanation:
Given data:
Number of molecules of bromine = 254 molecules
Number of moles = ?
Solution:
1 mole = 6.02 × 10 ²³ molecules
254 molecules × 1 mol / 6.02 × 10 ²³ molecules
42.2 × 10 ⁻²³ mol
4.22 × 10 ⁻²² mol
