Answer:
7.2
Explanation:
you first have to find the number of moles of nitrogen dioxide by using the number of moles for calcium nitrate and the mole to mole ratios
number of moles of calcium nitrate=mass/mm
=16.4/102
=0.16g/mol
then you use the mole to mole ratios
2 : 4
0.16: x
2x/2=0.64/2
x=0.32g/moles of nitrogen dioxide
then you use the formula for the volume
v=22.4n
=22.4×0.32
=7.2
I hope this helps

Electron structure of sodium:
₁₁Na: 1s²2s²2p⁶3s¹
Answer:
ionic bonding occurs between ions and covalent bonding occurs when atoms have electrons in common (they share).
Answer:
Diluted
Explanation:
Imagine having a sugar filled water (like a lot of them). This is a strong solution.
You can dilute this by adding more water to make it less concentrated.
