2LiOH(s) + CO2(g) → Li2CO3(s) + H2O(l)

Answer:

7.613 kg

Explanation:

Since you need a ratio of 2 moles of LiOH for each mole of CO2, you can find the mass of LiOH that you need. The first thing that you need to do is to find the number of moles that 3.575 L of carbon dioxide gas is. At STP, there are 22.4 liters of gas in a mole, meaning that there are about 0.159 moles of carbon dioxide. Multiplying this by 2 you get 0.318 moles. The molar mass of LiOH can be calculated by adding together the molar masses of each of the constituents. Lithium has a molar mass of 6.941, oxygen has a molar mass of about 16, and hydrogen a molar mass of about 1. Adding this together you get a molar mass of 23.941kg, which for 0.318 moles is just 23.941*0.318=7.613 kg. Hope this helps, and PM me with questions!

Why would a C-O bond have only provide 358 kJ/mol each while C=O provides 799 kJ/mol? Explain in detail.
Alina [70]

Consider the amount of energy needed to brake the bonds.

In c=o there are both a pi-bond and a sigma bond. Therefore it requires a higher energy to brake it. When considering the c-o bond there is only a single sigma bond is needed to be broken. Therefore braking is easier.

When something is easily broken they are having a weak attraction. When they harder to break they are having a stronger attraction.

Here weak attraction is having a lower energy while stronger attraction has higher energy.

Therefore c=o provides a high energy than c-o

What are the 3 common gases that give off reactions?
Serjik [45]

The 3 common gases that give off reactions are Hydrogen sulfide, Carbon monoxide, Nitrogen oxides.

<h3>What are off reactions</h3>

Off reactions are defined as chemical reactions that occurs when something burns or during combustion of materials which gives off energy.

Some gases that give off reaction are:

  1. Hydrogen sulfide
  2. Carbon monoxide
  3. Nitrogen oxides

Note that these gases are mostly poisonous.

Therefore, the 3 common gases that give off reactions are Hydrogen sulfide, Carbon monoxide, Nitrogen oxides.

ΑC2H6O+βO2 → γC2H4O2+δH2O
olga2289 [7]
Balancing the equation, we get:

2C₂H₆O + O₂ → 2C₂H₄O₂ + 2H₂O

So 
α = 2
β = 1
γ = 2
δ = 2

When a potassium ion (K+) moves from the soil into the vacuole of a cell on the surface of a root, it must pass through several
insens350 [35]
<h3><u>Answer;</u></h3>

C) primary cell wall → plasma membrane → cytoplasm → vacuole

<h3><u>Explanation;</u></h3>
  • The cell wall is the protective outer layer of a plant cell, that gives the cell strength and structure, and also filters molecules that pass in and out of the cell.
  • Cell membrane acts as a semi-permeable barrier separating the inside of the cell from the outside of the cell. The membrane allows regulation of what enters/exits the cell and how quickly.
  • Cytoplasm is the jelly-like fluid that fills a cell. It is responsible for giving a cell its shape and also helps to fill out the cell and keeps organelles in their place.
  • Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. They functional in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.
  • <u>Potassium ion from the extracellular environment will move to the cell vacuole via the cell wall, the cell membrane and then via the cytoplasm to the vacuole.</u>
