DONE
Intro
Boyle's law states that If the pressure on a gas is increased, then its volume will decrease because the gas molecules will gets closely packed at high pressure.
What is Boyle's law?According to Boyle's law, at constant temperature the volume of a gas is inversely proportional to the pressure. Therefore, as the pressure is increased, volume of the gas is decreased.
The volume of a gas is the total space it occupied . The gaseous particles can diffuse anywhere at low pressure and they not collide each other at this maximum spreading condition.
When the pressure is increased, the force of intermolecular attraction increases make them more compressed and the space occupied by them that is the volume of the gas reduces.

Is this a balanced equation? 4NH3+ 5O2 – 4NO + 5H20
Answer:
The reaction is not balanced.
Explanation:
The reaction expression is given as:
4NH₃ + 5O₂ → 4NO + 5H₂O
In a balanced reaction equation, the number of atoms on both sides of the expression is the same.
Now let us investigate;
Elements N H O
Reactants 4 12 10
Products 4 10 9
We see that the number of H and O on both sides of the expression is not the same. The reaction is not balanced.

What would happen to the rate of evaporation if you moved all the containers outdoors into direct sunlight?
Answer:
Molecules contained in a liquid evaporate from the surface area. This means that the larger the surface area, the faster the rate of evaporation. ... This means all the other factors that affect the rate of evaporation are identical. Leave the containers for one hour.
Explanation:
Answer:
Evaporation would accelerate.
Explanation:
Direct sunlight increases the thermal energy on the containers, increasing evaporation.

A 328-g sample of water absorbs 5.78 × 103 J of heat. Calculate the change in temperature for the water. If the water is initially at 25.0 °C, what is its final temperature?
Answer:
The change in temperature for the water is 4.21 C and its final temperature is 29.21 C
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
Q= 5.78*10³ J c= 4.186 [tex]\frac{J}{g*C}[/tex] m= 328 g ΔT= Tfinal-TinitialReplacing:
5.78*10³ J= 4.186 [tex]\frac{J}{g*C}[/tex] *328 g* ΔT
Solving:
ΔT= [tex]\frac{5.78*10^{3} J }{4.186\frac{J}{g*C}*328 g}[/tex]
ΔT= 4.21 C
Being ΔT= Tfinal - Tinitial and Tinitial=25 C, then:
4.21 C= Tfinal - 25 C
4.21 C + 25 C= Tfinal
29.21 C= Tfinal
The change in temperature for the water is 4.21 C and its final temperature is 29.21 C
Above is a solubility curve for KNO3.
Solubility has nothing to do with the speed of dissolving; it's a measure of how much salt will dissolve at a given temperature.
The y-axis of the graph shows you how much KNO3 will dissolve in 100 g of water. In other words, it tells you the maximum amount of solute that will dissolve at different temperatures.
The x-axis tells you the minimum temperature needed to dissolve different amounts of KNO3 in 100 g of water.
Approximately how many grams of KNO3 will dissolve in 100 g water at 0 degrees Celsius?

Which of these characteristics will produce the most water dense water
Answer:
High salinity, low temperature.
Explanation:
A lot of salt is left behind. This leads to water with very high salinity
The salinity of the water increases as more salt is dissolved in it. High temperature, density and salinity produce the most dense water.
What is salinity of water ?Salinity influences the physical properties of water, such as density and heat capacity, together with temperature and pressure.
When two water samples of the same volume are compared, the water sample with the higher salinity will have more mass and be more dense.
The ocean's salinity is raised by both sea ice production and ocean water evaporation. However, processes that reduce salinity, such as the ongoing inflow of fresh water from rivers, precipitation of rain and snow, and melting of ice, constantly balance out these "salinity rising" causes.
Thus, salinity ,density and high temperature produce the water dense.

Bonding in chemistry is known as chemical bonding which means the interaction or attraction between molecules.
Chemical bonds are of different type such as ionic, covalent, hydrogen, and metallic. Ionic bonds are formed by the transfer of valence electron from one atom to other and there is unequal distribution of electrons between two or more atoms. Ionic bonds forms two oppositely charges ions positively charged (loses electron) or negatively charged (gains electron).
Covalent bond are the strong chemical bonds that form due to equal sharing of electron pairs between atoms. They form a stable element and have stable attraction or repulsive forces.
