1) Chemical equation:
2CO + O2 ---> 2CO2
2) molar ratios 2 moles CO : 1 mol O2 : 2 moles CO2.
3) When temperature and pressure is kept constant, the molar ratios are equal to the volume ratios.
So, at the same temperature and pressure conditions (standard) you ca state
2 L CO : 1 LO2 : 2 L CO2
=> 2L CO : 2 L CO2 => 1L CO : 1 L CO2.
So, 1 liter of CO2 is produced when 1 liter of CO reacts with excess O2.
Answer:
A. to absorb carbon dioxide from the atmosphere and use it to make sugar
Explanation:
Green plants with the help of their green coloring pigment called chlorophyll helps to absorb sunlight. This sunlight helps in the process Called photosynthesis in which plants manufacture food (sugar) using CO2(Carbon dioxide)and Water to give Oxygen and Sugar. The oxygen is released back into the atmosphere.
The answer is <span>1.63 × 1024 atoms Fe.

Avogadro's number is the
number of units (atoms, molecules) in 1 mole of substance:
<span>6.023 × 10²³ atoms per 1 mole
</span>So, how many atoms are per 2.70 moles:
6.023 × 10²³ atoms : 1 mole = x : 2.70 moles
x = 6.023 × 10²³ atoms * 2.70 moles : 1 mole
x = 16.3 × 10²³ = 1.63 × 10 × 10²³ = 1.63 × 10²⁴ atoms
Answer:
1.4 moles/ 2.0 L= 0.7 M
Explanation: Molarity= moles of solute/ Liters of solution
therefore just plug the numbers in and you'll find the molarity to equal. 0.7
