Answer:

5C+2H_2+O_2\rightarrow C_5H_1_0O_2

Explanation:

Hello there!

In this case, according to the given information, and considering that the molecular formula of 3-methylbutanoic acid is:

C_5H_1_0O_2

Thus, the formation reaction is:

C+H_2+O_2\rightarrow C_5H_1_0O_2

However, it must be balanced because of the unequal number of carbon and hydrogen atoms yet those of oxygen seem to be balanced:

5C+2H_2+O_2\rightarrow C_5H_1_0O_2

Regards!

How many oxygen atoms are in 10.0g of 2Al2 CO3 3
LekaFEV [45]

Answer:

0.776 ×10²³ atoms of oxygen

Explanation:

Given data:

Mass of Al₂CO₃ = 10.0 g

Number of atoms of oxygen = ?

Solution:

Number of moles of Al₂CO₃:

Number of moles = mass/molar mass

Number of moles = 10.0 g/233.99 g/mol

Number of moles = 0.043 mol

1 mole of Al₂CO₃ contain 3 mole of oxygen.

0.043 ×3 mol = 0.129 mol

Number of atoms of oxygen:

1 mole contain 6.022×10²³ atoms

0.129 mol × 6.022×10²³ atoms / 1mol

0.776 ×10²³ atoms of oxygen

How many electrons can be held in the second orbital (closest to the nucleus)
anzhelika [568]
A valence electron structure would be like this 1s^2 2s^2 2p^6 etc 
1s^2 would be 2, 2s^2 would be 4, 2p^6 would be 12 and so on and so forth.

What is the price coke difference between a strong and weak acid?
KATRIN_1 [288]

Explanation:

Strong acids are those that are completely ionized in body fluids, and weak acids are those that are incompletely ionized in body fluids. Hydrochloric acid (HCl) is considered a strong acid because it is present only in a completely ionized form in the body, whereas carbonic acid (H2 CO3) is a weak acid because it is ionized incompletely, and, at equilibrium, all three reactants are present in body fluids. See the reactions below.

H2 CO3 (acid)↔H+ + HCO3- (base)

  <span>From the balanced equation: 
4mol Fe will produce 2mol Fe2O3 
Molar mass Fe = 55.847g/mol 
16.7gFe = 16.7/55.847 = 0.3mol Fe 
This will produce 0.15mol Fe2O3 
Molar mass Fe2O3 = 159.6887 g/mol 
0.15mol = 159.6887*0.15 = 23.95g Fe2O3 produced
Hope this helps</span>

Which atom in the ground state has a stable valence electron configuration?
Alecsey [184]
(1) Ar is your answer. Argon is a noble gas, which is stable in its standard valence electron configuration because it already completed its valence shell following the octet rule.
