Energy 1:Question 3

Chemistry
1 answer:
liberstina [14]2 years ago

Answer: The statement, atoms in the sand were moving more quickly best describes why the  temperature of the sand increased.

Explanation:

As Sun rises in the morning everyday and the heat energy radiations given by the Sun falls on a number of objects on our surroundings. As a result, the objects absorb this heat energy till afternoon due to which they become hot.

Hence, atoms of the objects gain kinetic energy due to which they move quickly. This shows that the temperature of the object (sand here) increases.

When Maria walked in the same area in the afternoon, the sand was hot as its particles have gained kinetic energy due to which they move rapidly from one place to another. Hence, sand feels more hot in the afternoon in the same area where she walked.

Thus, we can conclude that the statement the atoms in the sand were moving more quickly best describes why the  temperature of the sand increased.

Predict and Balance the following reaction:
Umnica [9.8K]

A. The balanced chemical reaction of Sodium metal and Water is 2Na  +  2H₂O  →  2NaOH    +   H₂.

<h3>What is a balanced chemical equation? </h3>

A balanced equation contains the same number of each type of atoms on both the left and right sides of the reaction arrow.

<h3>Reaction of Sodium metal and Water</h3>

Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2).

The balanced chemical reaction is written below;

2Na  +  2H₂O  →  2NaOH    +   H₂

Thus, the balanced chemical reaction of Sodium metal and Water is 2Na  +  2H₂O  →  2NaOH    +   H₂.

A student submits the following work on the mass number, but he has made a few mistakes. Select the sentences that are incorrect
rewona [7]

Answer

 

Calculating the mass number for an atom requires that we know the atomic number and the number of protons in the atom’s nucleus. The mass number then gives us the average weight of atoms of a given element. However, as long as the number of protons equals the number of neutrons, the values balance out and we always obtain a whole number for the mass number.
