Rom4ik [11]

Answer:

2.5m/s²

Explanation:

a = v/t

Where;

V = velocity (m/s)

a = acceleration (m/s²)

t = time (s).

According to the information provided in this question,

a = ?

v = 10m/s

t = 4

a = 10/4

a = 2.5m/s²

Which of these is an example of physical change?
Vsevolod [243]
I believe a physical change is one where the physical makeup of a substance is altered as opposed to a chemical change or molecular one which happens on a smaller scale. This would make me think that B. metal denting is accurate since all the other options are examples of chemical or molecular changes. A is an example of a liquid turning into a gas, which is a molecular change. The other two are chemical changes. Hope this is correct.

What are the missing coefficients needed to make this equation balanced from left to right?
12345 [234]

Explanation:

Since the equation is not given in this case, you can follow this explanation to balance it up.

A balanced chemical equation is one in which the law of conservation of matter is strictly obeyed.

According to the laws, we know that the total mass of the reacting substances must be equal to that of the product.

To do this, coefficients are usually assigned to chemical species.

In order to know the right coefficient one can use;

  • A trial by error method of inspecting and putting the appropriate coefficients in front of the formula of reactants or products.
  • A mathematical method in which simple equations are derived can be used.
