Answer:
An engine that creates ignites fuel with highly compressed air.
Similar to Cohesion, adhesion is the attraction between molecules of different substances . Water uses adhesion when it's attraction to another substance is greater than the water's attraction to itself. if you have ever dropped a cup of water on a hardwood floor,you know that it spreads out instead of foaming beads.
Answer:
1. The reaction will proceed backward, shifting the equilibrium position to the left.
2. The reaction will proceed forward, shifting the equilibrium position to the right.
3. Either add more of the products ( H2O or Cl2) or remove the reactant (HCl or O2)
Explanation:
Answer:
<u>CH</u>
Explanation:
Molecular formula of propene : <u>C₃H₆</u>
Take the HCF of carbon and hydrogen atoms :
Then, we can write the formula as :
- 3CH
- This means there are 3 moles present
Empirical Formula :
- Molecular Formula / No. of moles
- C₃H₆ / 3
- <u>CH</u>
<u></u>
The empirical formula of propene is <u>CH</u>
60.7 ml is the volume of a sample of CO2 at STP that has a volume of 75.0mL at 30.0°C and 91kPa.
Explanation:
Data given:
V1 = 75 ml
T1 = 30 Degrees or 273.15 + 30 = 303.15 K
P1 = 91 KPa
V2 =?
P2 = 1 atm or 101.3 KPa
T2 = 273.15 K
At STP the pressure is 1 atm and the temperature is 273.15 K
applying Gas Law:
= 
putting the values in the equation of Gas Law:
V2 = 
V2 = 
V2 = 60.7 ml
at STP the volume of carbon dioxide gas is 60.7 ml.
