Answer:
the left side are the reactants and the right side is the products
Explanation:
The reactants are the elemental compounds that are being turned into the product
Answer:
boiling water
Explanation:
boiling water produces more severe burns
Answer:
Temperature, heart rate and blood flow.
Explanation:
A sample 0. 100 moles of a gas is collected at at STP . 2.24 is the volume of the gas in liters.
The STP means standard temperature and pressure.
At STP,
Temperature = 0 °C =273 K
Pressure = 1 atm
We get value of volume by using ideal gas equation,
PV = nRT
- P is the pressure of the gas = 1 atm
- V is the volume occupied by the gas = ?
- n is the number of the moles = 1 mole
- T is the temperature of the gas = 273 K or 0 °C
- R universal gas constant = 8.31 J/ mole × K
Calculation,
Since, one mole of a gas occupy 22.4 L volume at STP
So, for 0.1 mole volume occupy = 22.4L × 0.1 mole/1 mole = 2.24L
