How many moles of oxygen are required to produce 37.15 g CO2? 37.15 g CO2 = mol O2
NNADVOKAT [17]

Answer:

0.84 moles of oxygen are required.

Explanation:

Given data:

Mass of CO₂ produced = 37.15 g

Number of moles of oxygen = ?

Solution:

Chemical equation:

C + O₂     →     CO₂

Number of moles of  CO₂:

Number of moles = mass/molar mass

Number of moles = 37.15 g/ 44 g/mol

Number of moles = 0.84 mol

Now we will compare the moles of oxygen and carbon dioxide.

                          CO₂         :       O₂  

                              1           :         1

                            0.84       :       0.84

0.84 moles of oxygen are required.

Alexeev081 [22]
Answer is: <span>Double Displacement.
Combustion is reaction with oxygen.
</span>Synthesis is reaction of two or more substances combining to make a more complex substance. 
Decomposition is reaction where one substance is broken down into two or more simpler substances. 
Single Displacement is reaction where  neutral element metal or nonmetal become an ion as it replaces another ion in a compound. 
<span>Double displacement reactions (more reactive metals displace metals with lower reactivity).
</span>Neutralization<span>is is </span>reaction<span> in which an </span>acid<span> and a </span>base<span> react quantitatively with each other.</span>

What is the concentration of a solution made with 0.150 moles of KOH in 400.0 mL of solution?
otez555 [7]

Answer:

concentration = \frac{0.15}{0.4}=0.375 mol/L

Explanation:

Concentration: i is defined as the mole per litre.

concentration = \frac{mole}{volume in L}

mole=0.15

volume=400 ml=0.4 litre

concentration = \frac{0.15}{0.4}=0.375 mol/L
