Explanation:
First convert the amount of water into moles:
360 g H2O ×
Now let's calculate the number of moles of O2 gas produced.
20 mol H2O ×
The volume of gas at 10°C and 5 atm can be found using the ideal gas law:
Answer:
The fire may grow bigger, depending on the gas.
Explanation:
If you expose more air to a small flame then it could grow larger because air keeps fire alive.
Answer:
So first formula of uniform acceleration is= a=(v-u)/t
Now use this formula and find the answer
Explanation:
Answer:
melting point,boiling point ,density,refractive index.
Explanation:
Molar mass NaOH =23+16+1=40 g/mol
<span> 0.100 M= 0.100 mol/L
</span>500 ml=0.500 L
0.500L*0.100 mol/L=0.0500 mol NaOH we need to prepare 500 ml solution
0.0500 mol NaOH*40g/1mol=2 g NaOH we need to prepare 500 ml solution
we need 2 g NaOH, dissolve it in small amount of water, and dilute it with water up to 500 mL
