What is the volume of the gas if there are 3.20 mol of gas at 265 K and 2.50 atm of pressure?
Answer:
27.81 L
Explanation:
Assuming the gas is ideal, we can solve this problem by using the following formula:
PV = nRTWhere:
P is Pressure, 2.50 atmV is Volumen is the number of moles, 3.20 molR is a constant, 0.082 atm·L·mol⁻¹·K⁻¹T is temperature, 265 KWe input the data:
2.50 atm * V = 3.20 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 265 KAnd solve for V:
V = 27.81 LWhat locations are likely to be affected by an earthquake or tsunami?

Jim makes a mixture which contains 10 mg of salt, 30 mg of sand, and some iron filings. The total mass of the mixture is 100 mg
Which amount of iron filings does Jim use in the mixture?
A10
B30
C40
D60
Answer:
Amount of iron fillings in mixture = 60 mg
Explanation:
Given:
Total mass of mixture = 100 mg
Amount of salt in mixture = 10 mg
Amount of sand in mixture = 30 mg
Find:
Amount of iron fillings in mixture
Computation:
Using Law of Conservation of mass;
Total mass of mixture = Amount of salt in mixture + Amount of sand in mixture + Amount of iron fillings in mixture
100 = 10 + 30 + Amount of iron fillings in mixture
100 = 40 + Amount of iron fillings in mixture
Amount of iron fillings in mixture = 100 - 40
Amount of iron fillings in mixture = 60 mg

Given the reaction: N2(g) +2O2(g) ⇌ 2NO2(g) The forward reaction is endothermic. Determine which of the following changes would result in more product being produced.
I. Increase NO2
II. Decrease O2
III. Add a catalyst
IV. Increase the temperature
V. Increase the pressure
A. I and II
B. II, III, and V
C. IV and V
D. II and IV
Answer:
C
Explanation:
increasing the temperature will favour the forward reaction therefore the reaction system will try to counteract that by producing more heat and NO2 therefore increases the amount of products produced
increasing the pressure will favour the forward reaction as it has more moles of substance therefore if the forward reaction is favored, more product will be produced
Answer:
C.) lV and V

What happens to iron when it melts?
O A. It undergoes a chemical change.
O B. It undergoes a physical change.
O c. Its atoms break apart and form new atoms.
O D. Its atoms combine and form new atoms.
Answer:
B. It undergoes a physical change.
Explanation:
Hello there!
In this case, since we know that chemical changes lead to the formation of new atoms and/or compounds due to the bonds rearrangement of the initial substances and the physical changes occur without changing the composition of the initial substances, we can infer that, since melting is a process that changes the phase of matter from solid to liquid without changing the identity of the initial substance, the answer to this question would be B. It undergoes a physical change. because the other options describe chemical changes.
Best regards!
Answer:
B. It undergoes a physical change.
Explanation:
At room temperature, the iron atoms are in an unusual loosely packed open arrangement; as iron is heated past 912 degrees Celsius, the atoms become more closely packed before loosening again at 1,394 degrees Celsius and ultimately melting at 1,538 degrees Celsius.
Which is true regarding pressure?
A.) at high pressure, the molecules are moving slower and therefore hitting other particles and the sides of a container less frequently
B.) pressure is calculated by combining the amount of space an entire object takes up.
C.) pressure is calculated by averaging the kinetic energy of all particles in a container
D.) at higher pressure indicates that particles are colliding with the walls of a container more frequently
Answer:
D
Explanation:
The higher a pressure in a system the faster the molecules within it move and collide with one another due to lack of space

The electrolyte magnesium chloride (MgCl2) will break up into how many individual particles in water (what is the i value)?
Answer:
Solid magnesium chloride is a non-conductor of electricity because the ions aren't free to move. However, it undergoes electrolysis when the ions become free on melting. Magnesium chloride dissolves in water to give a faintly acidic solution (pH = or 6).

When 50.0 liters of oxygen at 20.0 oC is compressed to 40.0 liters, what must the new temperature be to maintain constant pressure?
Answer:
234.52 K
Explanation:
Use V₁T₂ = V₂T₁
V₁ = 50 LV₂ = 40 LT₁ = 20°C = 293.15 K (20 + 273.15 = 293.15)(50 L)(T₂) = (40 L)(293.15 K)
T₂ = 234.52 K

Electricity generated from any source comes with its own advantages and
disadvantages. So, no source of energy for generating electricity is perfect. However,
imagine that there is an energy source that perfectly meets the needs of society.
Describe this ideal source of energy. Include relevant factors such as cost, supply, safety,
reliability, and environmental impact
Answer:
Wind energy
Explanation:
An ideal source of energy needs to be reliable, cost effective, safe and must lead to almost zero adverse environmental impact.
Wind energy is energy obtained from air moving at high velocity. This energy is harvested using windmills which convert mechanical energy to electrical energy.
Wind is inexpensive because it occurs naturally. However, a large expanse of land is required in order to mount sufficient number of windmills that will generate enough electrical energy for practical purposes.
This method of electricity generation is safe and does not lead to any environmental hazard unlike the burning of fossil fuels, use of nuclear energy or loss of habitat due to hydroelectric power generation.

A weather balloon calibrated at 0.00 degrees Celsius to have a volume of 20.0 L has what volume in L at -22.8 degrees Celsius pressure is held constant?
Answer:
New volume = 18.33 L
Explanation:
Given that,
Initial temperature, [tex]T_1=0^{\circ} C=273.15\ K[/tex]
Initial volume, [tex]V_1=20\ L[/tex]
Final temperature, [tex]T_2=-22.8^{\circ}C=250.35\ K[/tex]
We need to find the final volume when pressure is held constant. The relation between volume and temperature is given by :
[tex]V\propto T\\\\\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{20\times 250.35}{273.15}\\\\V_2=18.33\ L[/tex]
So, the new volume is equal to [tex]18.33\ L[/tex].
