from the cell to the air.
from the water to the cell.
from the nucleus to the mitochondria.
Photosynthesis is the process in plants to make their food. This involves the use carbon dioxide to react with water and make sugar or glucose as the main product and oxygen as a by-product. I think the best answer would be the first statement.
Answer: Option A
Explanation:
Photosynthesis is a process that helps the plants to make food by the help of carbon dioxide from the atmosphere and water, nutrients from soil and converts it into glucose in the presence of sunlight.
Atmosphere is a non living component of environment where carbon dioxide is present and it is transferred to plants which is a living component of ecosystem.
Answer:
1. How many ATOMS of boron are present in 2.20 moles of boron trifluoride? atoms of boron.
2. How many MOLES of fluorine are present in of boron trifluoride? moles of fluorine.
Explanation:
The molecular formula of boron trifluoride is .
So, one mole of boron trifluoride has one mole of boron atoms.
1. The number of boron atoms in 2.20 moles of boron trifluoride is 2.20 moles.
The number of atoms in 2.20 moles of boron is:
One mole of boron has ---- atoms.
Then, 2.20 moles of boron has
-
2. Calculate the number of moles of BF3 in 5.35*1022 molecules.
One mole of boron trifluoride has three moles of fluorine atoms.
Hence, 0.0888moles of BF3 has 3x0.0888mol of fluorine atoms.
=0.266mol of fluorine atoms.
Answer:
Double Displacement Reaction
Explanation:
A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products. Usually, a double displacement reaction results in precipitate formation.

Answer : The mass percentage of carbon in sucrose is, 42.1 %
Explanation: Given,
Molar mass of C = 12 g/mole
Molar mass of H = 1 g/mole
Molar mass of O = 16 g/mole
First we have to calculate the molar mass of sucrose.
Molar mass of sucrose =
Now we have to calculate the mass of carbon in 5 g of sucrose.
As we now that there are 12 number of carbon atoms, 22 number of hydrogen atoms and 11 number of oxygen atoms.
The mass of carbon =
As, 342 g of sucrose contains 144 g of carbon
So, 5 g of sucrose contains of carbon
Now we have to calculate the mass percentage of carbon in sucrose.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the mass percentage of carbon in sucrose is, 42.1 %
