Fiona followed these steps for a scientific investigation: 1. Collect baking soda and vinegar 2. Pour baking soda into a bowl. 3
horrorfan [7]

<u>Answer:</u> The correct statement is combining baking soda and vinegar will cause a chemical change.

<u>Explanation:</u>

A chemical reaction is defined as the reaction in which two or more chemical substances react to form two or more different chemical substances

A new substance (product) is formed in a chemical reaction when the bonds between the reactants are broken so that the new bonds between the products can be formed.

A physical process is defined as the process in which the physical state of matter takes place. Like, in the process of vaporization, a liquid state changes to the gaseous state without changing the composition of species.

When baking soda (Sodium bicarbonate) is reacted with vinegar (acetic acid), it leads to the formation of sodium acetate, water, and carbon dioxide.

A new compound is getting formed in this process which is denoted by the chemical equation:

NaHCO_3+CH_3COOH\rightarrow CH_3COONa+H_2O+CO_2

Hence, the correct statement is combining baking soda and vinegar will cause a chemical change.

Which term describes the wave phenomenon in the image?
VashaNatasha [74]

Answer:

wave changes its path from its initial direction so this phenomenon is known as Refraction of wave

Explanation:

When wave travels from one medium to other medium the due to change in the speed of the wave propagation it deviates from its initial path.

The deviation of the wave from its initial path is known as refraction of wave

Here we can see that wave incident on medium 1 with some angle with the boundary

Then it enters into other medium and then travels in other direction

So here wave changes its path from its initial direction so this phenomenon is known as Refraction of wave

Why don’t all thermodynamically favored reactions occur rapidly?
Elan Coil [88]

Answer:

b

Explanation:

A thermodynamic-ally favored reactions are nothing but spontaneous reactions. In spontaneous reactions ΔH (enthalpy) is always negative and ΔS( entropy) is always positive.

Now all thermodynamic-ally favored reactions does not occur rapidly because the reactants still need to break bonds and overcome the activation energy in order to form products.
