When glucose is consumed, it reacts with oxygen in the body to produce carbon dioxide, water, and energy. How many grams of carbon dioxide would be produced if 45g of C6H12O completely reacted with oxygen
Answers
Answer:
There will be produced 66g of CO2 if 45g of glucose completely reacted with oxygen
Explanation:
Step 1 : Balance the formula
Oxidation of glucose can be shown in the following equation :
C6H12O6 + 6 O2 → 6 CO2 + 6H2O
This means that for 1 mole glucose that react there will react 6 moles of O2, to form 6 moles of CO2 and 6 moles of H2O
Step 2: Calculating moles
mole glucose = 45g / Molar mass glucose
⇒ Molar mass = 6*12 + 12*1 + 6*16 = 72 + 12 + 96 = 180g/mole
⇒ mole glucose = 45g / 180g/mole
⇒mole glucose = 0.25 mole
Since 1 mole of glucose is used to form 6 moles of CO2
0.25 mole of glucose is used to form 1.5 moles of CO2
Step 3 : Calculating mass of Carbon dioxide
Mass of CO2 = 1.5 moles of CO2 * 44 g/mole
mass of CO2 = 66g
There will be produced 66g of CO2 if 45g of glucose completely reacted with oxygen
Final answer:
If 45g of glucose reacts with oxygen, 66.015 grams of carbon dioxide would be produced. This calculation is based on converting the mass of glucose to moles, using the stoichiometry of the balanced chemical equation, and then calculating the mass of CO2 produced.
Explanation:
When glucose (which has the chemical formula C6H12O6) is consumed, it reacts with oxygen to produce carbon dioxide, water, and energy. The chemical equation for this reaction is C6H12O6 + 6 O2 → 6 CO2 + 6 H2O. Given that 45g of C6H12O6 completely reacts with oxygen, we need to calculate the mass of carbon dioxide produced from this reaction.
To do this, we first need to determine the molar mass of glucose, which is 180.16 g/mol. This means that 1 mole of glucose weighs 180.16 grams. We can then find out how many moles of glucose 45g represents by dividing 45g by 180.16 g/mol, which gives us 0.25 mol of glucose.
According to the chemical equation, 1 mole of glucose produces 6 moles of CO2. Therefore, 0.25 moles of glucose would produce 0.25 × 6 = 1.5 moles of CO2. The molar mass of CO2 is 44.01 g/mol, so the mass of CO2 produced by 0.25 moles of glucose is 1.5 moles × 44.01 g/mol, resulting in 66.015 grams of CO2. So, if 45g of C6H12O6 completely reacted with oxygen, 66.015 grams of CO2 would be produced.

Answer: STP
CaCO3 = 5 g
Convert gram to mol
100 g of CaCO3 = 1 mol
5 g of CaCO3 (n) = 5 g *(1 mol/100 g) = 0.05 mol
Gas law
PV =nRT
V = nRT/P
V = (0.05 mol * (0.08206 L atm /K mol) *273 K)/1 atm
V = 1.124 L

Final answer:
When 5.0 g of CaCO3 are treated with excess hydrochloric acid, it forms 1.118 L of CO2 gas at STP.
Explanation:
When 5.0 g of CaCO3 is treated with excess hydrochloric acid, it undergoes a chemical reaction and forms CO2 gas. To find the number of liters of CO2 formed at STP (standard temperature and pressure), we need to use the ideal gas law. The molar mass of CaCO3 is 100.09 g/mol, and 1 mol of CaCO3 produces 1 mol of CO2 gas. The volume of 1 mol of any gas at STP is 22.4 L. Therefore, we can calculate the number of moles of CaCO3, then convert it to moles of CO2 and finally to the volume of CO2 gas in liters.
Using the given information, we have:
Mass of CaCO3 = 5.0 g
Molar mass of CaCO3 = 100.09 g/mol
Moles of CaCO3 = Mass of CaCO3 / Molar mass of CaCO3
Moles of CO2 = Moles of CaCO3
Volume of CO2 at STP = Moles of CO2 * 22.4 L/mol
Plugging in the values, we get:
Moles of CaCO3 = 5.0 g / 100.09 g/mol = 0.04997 mol
Moles of CO2 = 0.04997 mol
Volume of CO2 at STP = 0.04997 mol * 22.4 L/mol = 1.118 L

Answer:
(3) esterification
Explanation:
1) Deposition is a process in which a vapor directly condenses into a solid. It is the reverse of sublimation and therefore a process which involves a physical/phase change.
2) Distillation is a process in which a liquid mixture is separated based on the differences in their boiling points. This is a physical separation and not any form of a chemical change.
3)Esterification is an organic reaction in which a carboxylic acid is treated with an alcohol to form an ester.
4) Sublimation is again a physical/phase change process in which a solid gets converted into a gas.
