Answer:
yes, as it helps to increase global warming and it's main cause is deforestation
Explanation:
as carbon dioxide is a greenhouse gas. It helps to increase global warming
Answer:
A. Limiting reactant is A.
B. Limiting reactant is A.
C. Limiting reactant is B.
D. Limiting reactant is B.
Explanation:
It is possible to find the limiting reactant for a reaction taking the moles of a reactant that will react and using the chemical equation find the moles of the other reactant you will need.
For the reaction:
2A + 4B → 3C
A. 2 moles A requires:
2molA×= 4moles of B
As you have 5 moles of B, <em>limiting reactant is A.</em>
B. 1,8 moles A requires:
1,8 molA×= 3,6 moles of B
As you have 4 moles of B, <em>limiting reactant is A.</em>
C. 3 moles A requires:
3 molA×= 6 moles of B
As you have just 4 moles of B, <em>limiting reactant is B.</em>
D. 22 moles A requires:
22 molA×= 44moles of B
As you have just 40 moles of B, <em>limiting reactant is B.</em>

You must use 2.50 mL of the concentrated solution to make 10.0 mL of the dilute solution.
We can use the dilution formula
<em>V</em>_1<em>C</em>_1 = <em>V</em>_2<em>C</em>_2
where
<em>V</em> represents the volumes and
<em>C</em> represents the concentrations
We can rearrange the formula to get
<em>V</em>_2 = <em>V</em>_1 × (<em>C</em>_1/<em>C</em>_2)
<em>V</em>_1 = 10.0 mL; <em>C</em>_1 = 5.00 g/100. mL
<em>V</em>_2 = ?; ____<em>C</em>_2 = 20.0 g/100. mL
∴ <em>V</em>_2 = 10.0 mL × [(5.00 g/100. mL)/(20.0 g/100. mL)] = 10.0 mL × 0.250
= 2.50 mL
