P1/V1=P2/V2
1/22.4=4/x
X=4 multiple by 22.4
V2=89.6L
Answer:
<h3>The answer is 20 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 16,000 g
volume = 800 cm³
We have

We have the final answer as
<h3>20 g/cm³</h3>

Answer:
nitrogen
Explanation:
as the group number increases, the atomic radius decreases
3Na2O(at) + 2Al(NO3)3(aq) —> 6NaNO3(aq) + Al2O3(s)
This is a double replacement reaction and NaNO3 is aqueous because Na is an alkali metal, plus nitrate is in the solution. Both of these are soluble. Al2O3 is not soluble because it does not contain any element that is soluble and is hence the precipitate.
Hope this helped!
