Classify the chemical equations as being balanced or not balanced.

Balanced:

CaO + 3C -> CaC2 + CO

2Mg + O2 -> 2MgO

Not Balanced:

Na + H2O -> 2NaOH + H2

4Fe + O2 > 2Fe2O3

Explanation:

To check if a chemical equation is balanced or not, you need to check if the equation has the same amount of each element in both sides.

CaO + 3C -> CaC2 + CO

Left:

Ca: 1

O: 1

C: 3

Right:

Ca: 1

O: 1

C:3

Balanced

Na + H2O -> 2NaOH + H2

Left:

Na: 1

H: 2

O: 1

Right:

Na: 2

H: 4

O: 2

Not Balanced

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
