Answer:
C5H12 + 8O2 → 6H2O + 5CO2
Explanation:
Pentane + Oxygen --> Water + Carbon dioxide
C5H12 + O2 --> H2O + CO2
The balanced equation is given as;
C5H12 + 8O2 → 6H2O + 5CO2
The principle is the law of conservation of matter that states that matter cannot be created nor destroyed. Hence, the reactants pretty much recombine to form the products.
The number of atoms remains conserved.
Electronic configuration is given by
- 1s orbital is filled
- 2s orbital is unfilled
So
Answer:
placing the reactants on a hot plate
Explanation:
If the temperature goes up, the reaction rate will increase. Because the particle will move faster and makes the kinetic energy larger.
Answer:
a. 0.026 M
Explanation:
Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:
Molarity = n/V
Where;
n = number of moles (mol)
V = Volume of solution (L)
Based on the information provided;
V = 23.2mL = 23.2/1000 = 0.0232 L
n = ?
To get the number of moles of KHP, we use the formula:
mole = mass/molar mass
mole (n) = 0.123/204.2
mole (n) = 0.0006024mol
Molarity = n/V
Molarity = 0.0006024 ÷ 0.0232
Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2
Molarity = 6.024/2.32 × 10^(-4--2)
Molarity = 2.59 × 10^-2
Molarity = 0.026 M
