What mass of oxygen is contained in a 5.8 g sample of NaHCO3?

Chemistry
1 answer:
White raven [17]3 years ago
4 0
Molar mass of NaHCO3 is 83.9. moles of Na...O3= 5.8/83.9
=0.0691
for every mole of Na..O3 there are 3 O
n(O) = n(NaHCO3) x3
        = 0.207
mass of O is the moles x molar mass (16)
therefore the mass of O is 3.3 grams

Can you use molecular orbital theory to explain why fluorine is such a highly reactive gas?
vivado [14]
The F2 molecular orbital diagram shows 4e- are in the highest energy antibonding (destabilizing) molecular orbitals resulting in a bond order = 1.

Single bonds are easier to break and therefore more reactive. So the answer is yes.

Identify the state of matter for A, B, and C.
drek231 [11]

Explanation:

A) particles are close together in random positions with about equal kinetic energy and intermolecular forces.

These points are about liquid state.

B) particles are close together in fixed positions with low kinetic energy

These points satisfy the qualities of Solid state

C)particles are far apart with greater kinetic energy and low intermolecular forces.

The above qualities are for Gaseous state of matter

A) Liquid

B)Solid

C)Gas

C2h4 3 o2 2 co2 2 h2o
Marat540 [252]
Use the question marck Moles of CO2
The the giving = 0.624 mol O2
Find the CF faction = 1 mole=  32.00 of O2

O= 2x16.00= 32.00amu ( writte this in the cf fraction)
SET UP THE CHART
Always start with the giving

0.624 mol O2    /  1mol of CO2
___________  / _____________ = Cancel the queal ( O2)
                       / 32.00c O2
                      /
                     /
Multiply the top and divide by the bottom 
0.624 mol CO x 1mol CO2 = 0.624 divide by 32.00 O2 =0.0195
You should look at the giving number ( how many num u gor ever there) 
Ur answer should have the same # as ur givin so 
= 0.0195 
= .0195 mol of CO2
