Answer:

C2H4O2 + 2O2 —> 2CO2 + 2H20

The coefficients are 1, 2, 2, 2

Explanation:

C2H4O2 + O2 —> CO2 + H20

To balance the above, do the following

Since there are 2 carbon on the left, put 2 in front of CO2, we have

C2H4O2 + O2 —> 2CO2 + H20

We have 4 hydrogen on the left, to balance it put 2 in front of H2O i.e

C2H4O2 + O2 —> 2CO2 + 2H20

Now, we have a total of 6 oxygen on the right side. To balance it, put 2 in front of O2:

C2H4O2 + 2O2 —> 2CO2 + 2H20

The coefficients are 1, 2, 2, 2

How many moles of C6H12O6 will be produced if 22 grams of CO2 are reacted

SSSSS [86.1K]

Answer:

60 grams

Explanation:

We have the balanced equation (without state symbols):

→

So, we would need six moles of carbon dioxide to fully produce one mole of glucose.

Here, we got

of carbon dioxide, and we need to convert it into moles.

Carbon dioxide has a molar mass of

g/mol

. So here, there exist

/mol

mol

Since there are two moles of

, we can produce

⋅

moles of glucose

(

)

We need to find the mass of the glucose produced, so we multiply the number of moles of glucose by its molar mass.

Glucose has a molar mass of

180.156

g/mol

. So here, the mass of glucose produced is

mol

⋅

180.156

mol

≈

to the nearest whole number.

So, approximately

grams of glucose will be produced.

Write and balance the combination reaction for the heating of solid magnesium in the presence of nitrogen gas. In a particular e

Makovka662 [10]

Answer:

The mass of magnesium that has been consumed, was 6.69 g

Explanation:

The reaction is this one:

3Mg (s) + N₂(g) → Mg₃N₂

3 moles of solid magnesium react with 1 mol of nitrogen, to make 1 mol of magnesium nitride.

If 9.27 grams of nitrogen react, we see that ratio is 1:1, so we make 9.27 grams of nitride.

Mass / Molar mass = Moles

9.27 g / 100.9 g/m = 0.092 moles

If we have 0.092 moles of nitride, ratio between Mg is 1:3 so, the rule of three will be:

1 mol of Nitride was produced by 3 moles of Mg (s)

0.092 moles of nitride were produced by, (0.092 .3)/1 = 0.275 moles

Mass og Mg = 24.3 g/m

Molar mass . Moles = Mass

0.275 m . 24.3g/m = 6.69 g

Calculate the pH of a C6H5OH phenol solution, whose hydronium ion concentration [H3O +] is 1.8 x 10e-5 M

Sidana [21]

Answer: The pH of phenol solution is 4.7

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydronium ion concentration.

$pH=-\log [H_3O^+]$

Given : $[H_3O^+]=1.8\times 10^{-5}M$

Putting in the values we get

$pH=-\log[1.8\times 10^{-5}M]$

$pH=4.7$

Thus pH of phenol solution is 4.7
