Carbon has the ability to form multiple bonds because it has four valence electrons. Having four valence electrons means that carbon has a lot of space to form bonds with other atoms, or multiple bonds, in order to reach the full octet.
Hope this helps!! :)
Answer:
958 g is the mass of LiOH that can react with all the CO₂
Explanation:
CO₂(g) + 2 LiOH(s) → Li₂CO₃(aq) + H₂O
We think in the reaction:
1 mol of carbon dioxide can react with 2 moles of lithium hydroxide.
First of all, we convert the mass of our reactant to mol:
880 g . 1mol /44g = 20 moles
As ratio is 1:2, 20 moles of CO₂ will react with 40 moles of LiOH.
Let's determine the mass:
40 mol . 23.95 g /1mol = 958 g
Answer:
C

Machines can be classified into two categories: Simple and Compound
A simple machine is a basic device used for applying a force to produce a certain outcome. for example: lever, wedge, inclined plane are all simple machines.
A compound machine is a combination of simple machines.
In the given example: Shovel is a compound machine which is a combination of wedge and lever.
The answer is steel because you cannot pick water, oxygen, or gold out of a mixture.
