Explanation:

Adding a neutron will not affect the charge. The atom remains neutrally charged.

Since the charge of a neutron is neutral, or 0, the charge is not affected. Protons have a positive charge, whereas electrons have a negative charge. Since there are an equal number of protons and electrons, they cancel out.

Adding a neutron also increases the mass by 1. The mass of a neutron is 1 amu. The atomic mass is calculated by protons + neutrons.

Originally, the mass is 7 (because 3+4). The mass would now be 8 (because 3+5).

A solution contains 14 grams of KCl in 100. grams of water at 40°C. What is the minimum amount of KCl that must be added to make

pashok25 [27]

Answer:

1386g

Explanation:

Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.

if 14g dissolved in 100cm3

the amount that will dissolve in 1000cm3 = 14 x 1000/ 100

=1400g

To form a saturated solution, 1400 - 14 = 1386g must be added.

Brainllest! Why are they called hot air balloons and not cold air balloons? Be sure to use the terms density, volume, and mass i

Feliz [49]

Hot air balloons have hot air inside them, which is less dense as the air around it. Thus it rises. A cold air balloon would sink because the air would be more dense than the air around it. Also, the balloon’s volume would vary in size depending on the weight of the balloon.

Dinitrogen pentoxide can be made by the reaction of nitrogen with oxygen. Consider the reaction

Rom4ik [11]

The only reactants are Nitrogen and Oxygen and the only product is dinitrogen pentoxide. Following the law of conservation of mass, the total amount of reactants must equal the total amount of products. Thus, the total mass of dinitrogen pentoxide:
35 + 48
= 83 grams
