Answer:
3.0x1p^24 molecules H2O=____5____ mol H2O
Explanation:
We une the number of Avogadro:
6, 02 x 10 ^23 molecules------- 1 mol
3, 01 x 10 ^24 molecules----x=
x= (3, 01 x 10 ^24 moleculesx 1 mol)/6, 02 x 10 ^23 molecules)
x= 5 mol
Answer:
V2= 531.4 ml
Explanation:
T1= 273+45 °C= 318 Kelvin
T2= 273+65 °C= 338 Kelvin
V1= 500ml *( 0.001L/1ml)= 0.5 Liters
V2= 
= 
= 0.5314465409 Liters* (1 ml/0.001 L)= 531.4 ml
Answer:
455.4 mmHg
Explanation:
To solve this problem we can use <em>Gay Lussac's Law</em>, which describe the temperature and pressure of a gas, at constant volume and composition:
In this case:
We <u>input the data</u>:
- 621 mmHg * 231 K = P₂ * 315 K
And <u>solve for P₂</u>:
Answer:
Explanation:
Electrons are the negatively charged particles of an atom that are involved in chemical reactions. They are located outside the nucleus of an atom
