What phase is carbon dioxide in at 5 ATM pressure and -20?
In these conditions carbon dioxide is a gas.
Which state of matter is carbon dioxide?
It exists either as a gas as carbon dioxide or CO2, or it is dissolved in water as H2CO3 (note that if you add the formulas for water and carbon dioxide, you get carbonic acid: H2O + CO2 --> H2CO3). You cannot have pure carbonic acid that is not in the presence of water, and thus H2CO3 exists ONLY as a dissolved solution in water.
What is the Henry's law constant for Carbon Dioxide at 20 degrees Celsius?
Henry's law constant for Carbon Dioxide at 20 degrees Celsius is: 1,6*10^3 ATM
How much volume of carbon dioxide is required to be bubbled through lime water to precipitate 20 gram of calcium carbonate?
To determine the volume of carbon dioxide needed, you would need to know the stoichiometry of the reaction between carbon dioxide and calcium carbonate. In this case, since 20 grams of calcium carbonate is given, you would convert that to moles using the molar mass of calcium carbonate. Then, using the balanced equation, you can determine the mole ratio between carbon dioxide and calcium carbonate. Finally, using the molar volume of carbon dioxide gas at the given conditions (usually 22.4 L/mol at standard temperature and pressure), you can calculate the volume of carbon dioxide needed.
Can Carbon Dioxide and Oxygen be found in air?
Oxygen makes up roughly 20% of the atmosphere. Carbon Dioxide makes up 0.035% of the atmosphere.
How much oxygen nitrogen carbon dioxide is there in the air you breathe out?
Oxygen---------- 4-5 % Carbon dioxide---------- 20% Nitrogen--------- 75%
What is normal range of carbon dioxide in blood?
20-29mEq/l
Why does carbon monoxide burn and carbon dioxide does not?
Carbon monoxide binds very tightly to heme; carbon dioxide does not. Carbon dioxide is not poisonous per se, but it's not harmless either; concentrations of carbon dioxide above 20% or so are pretty bad for you even if there's also plenty of oxygen to breathe.
What do you inhale when breathing?
Oxygen gas (when we exhale, we breathe out carbon dioxide).
How the atoms of carbon and oxygen in the carbon dioxide got into our bodies in the first place?
The air which we are breathing is containing about 20% ofcarbon dioxide which got into our bodies while breathing.
The are 6 grams of carbon and 20 grams of oxygen if 22 grams of carbon dioxide are produced and all the carbon is used how many grams of oxygen are left?
22 grams carbon dioxide (0.5 moles)
What gas is eliminated when you exhale?
Carbon dioxide is exhaled (whereas 20% oxygen is inhaled, since the vast majority of the remainder of inhaled air is composed of nitrogen, 79%).
