How many grams of carbon disulfide will react with 2.14 moles of oxygen
MAXImum [283]
Reaction: CS₂ + 3 O₂ → CO₂ + 2 SO₂

For every mole of CS₂, 3 moles of Oxygen formed. 
So, Number of moles of CS₂ = 2.14/3 = 0.713 mol

Now, Number of moles = Given mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 76 * 0.713        [ Molar mass of CS₂ = 76 g/mol ]
Mass = 54.21 g

In short, Your Final Answer would be: 54.21 Grams

Hope this helps!

Sea level changes occur at a rate of 10 m per 1,000 years. Regional erosion occurs at a rate of 2 m per 1,000 years. Uplift occu
PtichkaEL [24]
<h3>Answer:</h3>

The rate of sea level change is the fastest

<h3>Explanation:</h3>

To determine the process which is the fastest we need to determine the rate at which each occurs in meters per year.

Rate of sea level changes is 10 m per 1,000 years

Therefore, the rate of sea level change = 10 m ÷ 1000 years

                                                                 = 0.01 m/yr

Regional erosion occurs at 2 m per 1,000 years

Therefore, Rate in meters per seconds = 2 m ÷ 1,000 years

                                                                 = 0.002 m/year

Uplift occurs at a rate of 0.1 m per 1,000 years

Thus, rate in meters per seconds = 0.1 m ÷ 1,000 years

                                                       = 0.0001 m/yr

Therefore, the rate of sea level change is the fastest at a rate of 0.01 meter/year

What volume of stock solution and water must you add to prepare 36.25ml of a 1.25M solution
Serjik [45]

Given :

Number of moles , n = 36.25 mol .

Molarity , M = 1.25 M .

To Find :

The volume of water required .

Solution :

Moarity is given by :

M=\dfrac{n}{V}

So , V=\dfrac{n}{M}

Here , n is number of moles and M is molarity .

Putting all values in above equation , we get :

V=\dfrac{36.25}{1.25}\\\\V=29\ L

Therefore , volume of water required is 29 L .
