Answer:DNA
Explanation:I already do the test
The pressure that will be exerted if four sample of gas are placed in a single 3.5 container is calculated as below
if each gas occupies 675 mmhg
what about 4 gases in the sample
by cross multiplication
= 675 mm hg x 4/1 = 2.7 x10^3mmhg (answer D)
Answer:
It is made of atoms that are covalently bonded together.
Explanation:
For example the carbonate ion CO3++.
The carbon and oxygen atoms are held together by covalent bonds.
5 mols of O_2 need 4 mol NH_3
- As mols of ammonia are less Ammonia is limiting reagent
Now
Moles of Ammonia
- Given mass/Molar mass
- 4.65/17
- 0.3mol
Moles of NO=0.3mol
Mass of NO
So
Moles of Oxygen
Remaining moles
Mass
