Consider two ideal gases, A & B, at the same temperature. The rms speed of the molecules of gas A is twice that of gas B. Ho
uysha [10]

Answer:

option (d)

Explanation:

The relation between the rms velocity and the molecular mass is given by

v   proportional to  \frac{1}{\sqrt{M}} keeping the temperature constant

So for two gases

\frac{v_{A}}{v_{B}}=\sqrt{\frac{M_{B}}{M_{A}}}

\frac{2v_{B}}{v_{B}}=\sqrt{\frac{M_{B}}{M_{A}}}

{\frac{M_{B}}{M_{A}}} = 4

{\frac{M_{B}}{4}} = M_{A}

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.
