Answer:

2CO 2NO → 2CO2 N2 : Balanced

6CO2 6H2O → C6H12O6 : Unbalanced

H2CO3 → H2O CO2 : Balanced

2Cu O2 → CuO : Unbalanced

Explanation:

1.) 2CO 2NO → 2CO2 N2

2 Carbon 2

4 Oxygen 4

2 Nitrogen 2

The amount of atoms of each element on each side of the equation are the same therefore the equation is balanced.

2.) 6CO2 6H2O → C6H12O6 O2

6 Carbon 6

12 Oxygen 8

12 Hydrogen 12

The amount of oxygen atoms is different on both sides of the equation therefore the equation is not balanced.

3.) H2CO3 → H2O CO2

2 Hydrogen 2

1 Carbon 1

3 Oxygen 3

The amount of atoms of each element is the same on both sides of the equation therefore the equation is balanced.

2Cu O2 → CuO.

2 Cu 2

2 O 1

The amount of oxygen atoms is different on both sides of the equation therefore the equation is not balanced.

lesantik [10]

First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Carbonic acid slowly dissolves away minerals in rock, especially the carbonate minerals that make up limestone and marble. The weak acid decomposes the insoluble rock into watersoluble products that move into the groundwater.

The CO2 produced in one round of the citric acid cycle does not originate in the acetyl carbons that entered that round. If the
aleksley [76]

Answer:

It will require<u> second round</u> of the cycle to release 14C0_2

Explanation:

<u>Reason behind the requirement of second round of the cycle to release </u>CO_2 -:

The C4 carbon of succinyl CoA is acetyl from acetyl CoA. Succinyl CoA is converted to succinate, which is then converted to fumarate, fumarate, malate, and eventually oxaloacetate. 14C will be found in oxaloacetate at either C1 or C4. During the second round of the loop, each of these carbons will be converted to carbon dioxide.

How many hydrogen atoms are in 105 g of water?
mel-nik [20]
Moles of water atoms = mass/molecular weight = 105/18 = 5.83 mol. Number of moles of hydrogen in water = 2 x moles of water = 11.66. Number of H atoms in water = moles of hydrogen x 6.02 x 10^23 = 7.019 x 10^24 ~ 7.02 x 10^24 atoms. Hope this helps.
