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?
Answers
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
25.2 g of CuSO4 6H20 (mm: 267.72 g/mol) is dissolved in 28.0 mL of water, calculate the molarity.
Answers
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

2. How many moles are in 2.8 Liters of CO2 gas?
Answers
Answer:
0.125 moles
Explanation:
2.8 litres is equivalent to 2.8dm³
At STP,
1 mole = 22.4 dm³
x mole = 2.8 dm³
Cross multiply
22.4x = 2.8
Divide both sides by 22.4
x = 2.8/22.4
x = 0.125

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?
Answers
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.
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
Answers
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.

More bushes of potatoes will be produced if the soil is fertilized more WHAT IS THE INDEPENDENT VAIRABLE AND THE DEPENDENT VARIABLE
Answers
Answer:
The dependent variable is the bushes of potatoes while the soil is an independent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Hence, the dependent variable is the bushes of potatoes while the soil is an independent variable.
