Balance this chemical equation: CH4 + 02 -→ CO2 + H2O

CH4 + 2O2 > CO2 + 2H2O

Explanation:

What are the rules in balancing chemical equations

1 . Write the correct chemical formulas for all the reactants and products

2. Count the total number of atoms or ions of each element in the reactants and also of the product

3. Balance the elements one at a time using coefficient

4. Check each atoms or ions to ensure correctly balanced

5. Make sure that all the coefficient are in the lowest possible whole number ratio

CH4 + O2 > CO2 + H2O

reactant. Product

Write out each number of atoms of each element for both the reactant and the product

Reactant. Product

1 C 1C

4H 2H

2O 3O

balance each element at a time

CH4 + O2 > CO2 + H2O

let's balance H2O by adding coefficient of 2

CH4 + O2 > CO2 +2 H2O

since :H - 4 at the reactant and also at the product

: O - 4 at the product but 2 at the reactant

Let's add the coefficient of 2 to O to balance the equation

CH4 + 2O2 > CO2 + 2H2O

C. C

4H. 4H

4O. 2O + 2O = 4O

so our chemical equation is balanced

CH4 + 2O2 > CO2 + 2H2O

Explanation:

Balancing the Hydrogen atoms on the right side,

Balancing the Oxygen atoms on the left side,

clouds form

solid ice forms on leaves.

water droplets form on grass.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
