Now, of course, as chemists we deal with molar quantities, and the oxidation reaction must involve a series of complex elementary steps, but here the molecule is simply represented as

Why is it important for plants that carbon dioxide uptake at day should be greater then the release of carbon dioxide during night?
If the amount of Carbon Dioxide released in the process of respiration was greater than the amount of Carbon Dioxide used in the process of the plant would be "starving"...

There are 3 isotopes of carbon. Carbon-12, Carbon-13 and Carbon-14. The average atomic mass of carbon is 12.011. Which isotope of carbon is the most abundant? Why?
The relative of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass...

Carbon has a third isotope, named carbon-13. How many protons and neutrons are found in each atom of carbon-13. Carbon-13 is a stable isotope, like carbon-12. How useful would carbon-13 be for radiometric dating?
This is called the of the element. To make it up to 13 in carbon-13, you will need 7 neutrons. Stable isotopes are not useful at all in radio-dating,...

What kind of bonding is involved in carbon dioxide and silicon dioxide?
Now carbon dioxide is molecular (and we are exhaling it now!), and the normal Lewis structure is $O=C=O$. The central carbon is $"sp-hybridized"$; the terminal oxygens are $sp^2-"hybridized"$. On t'other...

When 3.0 g of carbon is burnt in 8.0 g of oxygen, 11.0 g of carbon dioxide is produced. what is the mass of carbon dioxide will be formed when 3.0 g of carbon is burnt in 50.0 g of oxygen? Which law of chemical combination will govern the answer?
When a $3.0*g$ mass of carbon is burnt in an $8.0*g$ mass of dioxygen, the carbon and the oxygen are stoichiometrically equivalent. Of course, the combustion reaction proceeds according to...

When burning 180 g glucose in the presence of the 192 g of oxygen, water and carbon dioxide are produced. If 108 g of water is produced, how much carbon dioxide is produced?
We're asked to find the mass of $"CO"_2$ produced in a given reaction, given that $108$ $"g H"_2"O"$ is formed. What we can do first is write the balanced chemical...

Space vehicles use solid lithium hydroxide to remove exhaled carbon dioxide according to the equation: $2LiOH+CO_2 ->Li_2CO_3+H_2O$. What is the mass of carbon dioxide removed if the space vehicle carries 42.0 mol $LiOH$?
From the reaction clearly 2 moles of lithium salt are required for the removal of 1 mole of carbon dioxide gas. Of course this molar quantity represents a precise mass....

In a combustion reaction, initially there were $77.8*g$ of oxygen gas, and a $22.8*g$ mass of carbon; $18.0*g$ of oxygen remained after the reaction. If the carbon were completely oxidized, what mass of carbon dioxide resulted?
$77.8*g-18.0*g$ oxygen gas reacted, and $22.8*g$ carbon was consumed. Given complete combustion, CLEARLY, $(59.8+22.8)*g=82.6*g$ $CO_2(g)$ were produced. Why $"CLEARLY?"$. Because mass is conserved in all chemical reactions. $"Garbage in must...

Ethene undergoes incomplete combustion to form carbon dioxide, carbon monoxide and water vapour. If the ratio of carbon dioxide to carbon monoxide formed is 9:1 when x cm^3 of ethene is burnt, what is the volume of oxygen gas consumed in the reaction?
Ethene undergoes incomplete combustion to form carbon dioxide, carbon monoxide and water vapour. The balanced equation of this incomplete combustion reaction is as follows. $C_2H_4(g)+5/2O_2(g)->CO_2(g)+CO(g)+2H_2O(g)$ But as per question the...

The solubility of carbon dioxide in water is 0.161 g $CO_2$ in 100 mL of water at 20°C and 1.00 atm. A soft drink is carbonated with carbon dioxide gas at 5.50 atm pressure. What is the solubility of carbon dioxide in water at this pressure?
$"8.855 g/L"$ This is just asking you to calculate the new molar (i.e. molar solubility) at a different pressure, i.e. use the . (We'll end up converting...
