Explanation:
Answer is: 4)Mass
I really hope this helped you out!!!!
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
Answer:
Archaea
Explanation:
Archaea are prokaryotic single cell microorganism.
They are usually found in extreme environment like hot thermal vent and others. They share characteristics with bacteria and eukaryote. Archaea as a prokaryotic organism they lack true nucleus and organelles but unlike bacteria they are unaffected by antibiotics and contain different cell wall components. Unlike bacteria and eukaryotes, their membranes contain branching lipids.
Answer:
Both are highly reactive.
Explanation:
A has 1 valence electron D has 3
A is sodium D is aluminum
