Answer:

0.34 moles of oxygen consumed 0.68 moles of magnesium

Explanation:

Given data:

Moles of magnesium = ?

Moles of oxygen = 0.34 mol

Chemical equation:

2Mg + O₂ → 2MgO

Now we will compare the moles of oxygen and magnesium:

O₂ : Mg

1 : 2

0.34 : 2×0.34 = 0.68 mol

Thus 0.34 moles of oxygen consumed 0.68 moles of magnesium.

Joe is concerned about the carbon dioxide emissions from his daily commute and the impact that it is having on global warming In

Vesna [10]

Amount of CO₂ emission per day is 11,356.23 g.

<u>Explanation:</u>

Joe travelling distance per day = 60 miles

Carbon dioxide emission per day = 20 mpg

Now we have to find the amount of carbon dioxide emitted per day by dividing the distance by the emission per day given in gallons.

Amount of Carbon dioxide emission = $$\frac{distance}{emission amount}$

Amount of CO₂ emission in gallons = $$\frac{ 60 miles}{20 mpg}$

= 3 gallons

Now we have to convert the gallons to grams as,

1 gallon = 3,785.41 g

3 gallons = 3 × 3785.41 g = 11,356.23 g

So the emission of CO₂ per day is 11,356.23 g.

yuradex [85]

Answer:

You need 8,324 g of CaCl₂ yo make this solution

Explanation:

Molarity is a way to express concentration in a solution, in units of moles of solute per liter of solution.

To know the grams of CaCl₂ it is necessary to know, first, the moles of this substance with the desired volume and concentration , thus:

0,1500 L × $\frac{0,500 mol}{L}$ = 0,075 CaCl₂ moles

Now, with the molar mass of CaCl₂ you will obtain the necessary grams, thus:

0,075 CaCl₂ moles × $\frac{110,98 g}{mol}$ = 8,324 g of CaCl₂

So, you need <em>8,324 g of CaCl₂</em> to make 150,0 mL of a 0,500M solution

I hope it helps!
