Answer:
120 kg m/s
Explanation:
The magnitude of the momentum of an object is given by
where
m is the mass of the object
v is its speed
For the block in this problem,
m = 10.0 kg (mass of the block)
v = 12.0 m/s (speed of the block)
Therefore the magnitude of the block's momentum is
<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:
Hence, the correct statement is combining baking soda and vinegar will cause a chemical change.
