Answer:
3.18 mol
Explanation:
n(CO2) = mass/ Mr.
= 25.5 / 16
= 1.59 mol
As per the equation above,
n(LiOH) : n(CO2)
2 : 1
∴ 3.18 : 1.59
Answer:
Lithium Fluoride
Explanation:
It should be lithium fluoride for sure :)
Answer:
A
Explanation:
Autotrophs utilize the energy from sunlight to reduce carbon dioxide to carbohydrates (glucose). The energy from the sunlight is used to split water into H+ and O2- and the H+ used in the reduction process. The labeled carbon in the carbon dioxide will, therefore, be incorporated by the autotrophs in the carbohydrates made in photosynthesis.
Heat energy is absorbed by the substance.
Answer:
271.0 L
Explanation:
Given data:
Number of moles of hydrogen = 12.1 mol
Volume = ?
Solution:
The one mole of gas at standard temperature and pressure occupy the volume of 22.4 L.
One mole volume = 22.4 L
For 12.1 mol,
12.1 mol × 22.4 L / 1 mol
271.0 L
Now by putting the standard conditions we can calculate the number of moles and check the answer weather it is wrong or right.
Formula:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
standard temperature = 273.15 K
standard pressure = 1 atm
Now we will put the values in formula.
PV = nRT
n = 1 atm × 271.0 L / 0.0821 atm.L/mol.K × 273.15 K
n = 271.0 L .atm / 22.4 atm. L/mol
n = 12.1 mol
so answer is correct
