In the given molecular formula of the aluminum sulphite which is Al2(SO3)3, this molecular formula there different type of elements are bonded together to form this compound each element has a specific number of atoms present. This compound has three elements that are aluminum, sulfur, and oxygen and the atoms are present are:
Al = 2 atoms represented by subscript
S = 3 atoms represented as whole subscripts of sulfite
O = 9 atoms 3 inside bracket and 3 outside of bracket that multiplies.
Thus, total number of atoms are 2+3+9 = 14
Explain how to count the number of elements in a compound.
Answer:
Simply identify what elements are in a compound

during the charging process, the allied liquid becomes gas. What happens to particles in the liquid
Answer: The particles need energy to overcome the attractions between them. As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles of gas in the liquid.

A sample of neon gas is at a temperature of 60°C and has a volume of 300 cm. What is the volume of the gas if it is heated to 100°C at a constant pressure?
Answer:
336.04 cm
Explanation:
T1 = 60+273 = 333K
T2 = 100+273 = 373K
V2 = (V1×T2)/T1
V2 = 300×373/333
V2 = 336.04 cm

We have that for the Question "" it can be said that the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is
Amount of CO_2(g)=221.35g
From the question we are told
What is the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules?
Generally the equation for the is mathematically given as
[tex]No moles in 3*02*10^{24}=\frac{3.03*10^{24}}{6.023*10^-{23}}[/tex]
No moles in 3*02*10^{24}=5.03moles
Amount of CO_2(g)=5.03moles *44g/mol
Amount of CO_2(g)=221.35g
Hence
the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is

There is a very slight change in gravity at the top of a mountain. Which property would most likely be less at the top of a mountain?
mass
weight
body density
body temperature
Answer:
The entity that decreases is the Weight.
Explanation:
Every object on the surface of the earth is usually pulled downwards by the action of gravity. The force or weight is W = mg
Now, the farther one gets away from the surface of the earth by climbing a mountain, the further the person is from the Earth's centre of gravity.
We know that the formula for Force of gravity away from the Earth's surface is given by;
F_g = GM1M2/r²
So the greater the distance, the lesser the gravitational force.
Now, the gravitational force equals the weight of the individual.
Thus, the entity that decreases is the Weight of the individual.

The initial pressure of a balloon floating in the air is 0.53 atm. After the balloon has reached a certain point in the sky, the volume of the air particles in the balloon is 4.3 liters at a final pressure of 0.42 atm. What was the initial volume of the balloon?
Answer:
The initial volume of the balloon is 3.41 L.
Explanation:
The gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature, and moles.
As the volume increases, the gas particles (atoms or molecules) take longer to reach the walls of the container and therefore collide with them fewer times per unit of time. This means that the pressure will be lower because it represents the frequency of collisions of the gas against the walls. In this way pressure and volume are related, determining Boyle's law which says:
"The volume occupied by a certain gaseous mass at constant temperature is inversely proportional to pressure"
Boyle's law is expressed mathematically as:
Pressure * Volume = constant
or P * V = k
Now it is possible to assume that you have a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:
P1 * V1 = P2 * V2
In this case:
P1= 0.53 atmV1= ?P2= 0.42 atmV2= 4.3 LReplacing:
0.53 atm* V1= 0.42 atm* 4.3 L
Solving:
[tex]V1=\frac{0.42 atm* 4.3 L}{0.53 atm}[/tex]
V1= 3.41 L
The initial volume of the balloon is 3.41 L.

25.2 g of CuSO4 6H20 (mm: 267.72 g/mol) is dissolved in 28.0 mL of water, calculate the molarity.
Answer:
3.36 M
Explanation:
Step 1: Given data
Mass of CuSO₄.6H₂O (m): 25.2 gMolar mass of CuSO₄.6H₂O (M): 267.72 g/molVolume of solution (V): 28.0 mL (we will assume it is equal to the volume of water)Step 2: Calculate the moles (n) of CuSO₄.6H₂O (solute)
We will use the following expression.
n = m/M
n = 25.2 g / (267.72 g/mol) = 0.0941 mol
Step 3: Calculate the molarity
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.0941 mol/0.0280 L = 3.36 M

How could a scientist use a sedimentary rock to provide evidence that the right k cycle is a valid scientific model
Answer:
By closely observing the sedimentary rock and the presence of organic materials and mineral grains in sedimentary rocks
Explanation:
The rock cycle explains how the three types of rock are formed over time from each other.
To use a sedimentary rock to prove that the rock cycle is a valid scientific model is by, closely observing the sedimentary rock. when the sedimentary rock is closed observed the principle of superposition will be seen ( i.e. younger segments deposited on top ), the presence of organic materials and mineral grains that can be found in Igneous or Metamorphic rocks can also be seen and this shows that Sedimentary rocks pass through the rock cycle. hence this proves that the rock cycle is a valid scientific model overtime
