Help would be greatly appreciated, thank you!! :) What is the relationship between Pressure (P) and Volume (V)?
1. Inversely proportional
2. Directly proportional
3. There is no relationship
3. Hydrogen gas was cooled from 150°C to 50 °C. Its new volume is 75.0mL.
What was its original volume?
Answer:98
Explanation:X/423 = 75.0/323 X = 98
Considering the Charles' Law, the original volume is 98.22 mL.
Charles' LawCharles' Law consists of the relationship that exists between the volume and the temperature of a certain amount of ideal gas, which is maintained at a constant pressure.
This law states that for a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of movement that they have. the gas molecules. That is, the volume is directly proportional to the temperature of the gas.
Mathematically, Charles' law states that the ratio between volume and temperature will always have the same value:
[tex]\frac{V}{T}=k[/tex]
Considering an initial state 1 and a final state 2, the following is true:
[tex]\frac{V1}{T1}=\frac{V2}{T2}[/tex]
Original volume in this caseIn this case, you know:
V1= ?T1= 150 °C= 423 K (being 0 °C= 273 K)V2= 75 mLT2= 50 °C= 323 KReplacing in Charles's law:
[tex]\frac{V1}{423 K}=\frac{75 mL}{323 K}[/tex]
Solving:
[tex]V1=\frac{75 mL}{323 K}423 K[/tex]
V1= 98.22 mL
In summary, the original volume is 98.22 mL.

how much energy would be lost by 23 g of water if it was heated until it was 78 degrees celsius and then allow to cool down to 27 degrees celsius
Answer:
Q = -4903.14 j
Explanation:
Given data:
Mass of water = 23 g
Initial temperature = 78°C
Final temperature = 27°C
Heat lost = ?
Solution:
Specific heat capacity of water is 4.18 J/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 27°C - 78°C
ΔT = -51°C
Q = 23 g × 4.18 J/g.°C × -51°C
Q = -4903.14 j (negative sign shows heat is released)

The order of the radiations from longer wavelength to shorter wavelength is as follows: Radio waves , microwave, infrared, visible light, ultraviolet, X-rays and gamma rays. In these order the blanks have to be filled.
What is electromagnetic spectrum?Electromagnetic spectrum is the arrangement of radiations in the order of decreasing wavelength or increasing frequency. Frequency is the number of wave cycles per unit time.
All the electromagnetic radiations are transverse waves. Wavelength of an electromagnetic radiation is the distance between two consecutive crests or troughs or the waves.
As the wavelength increases frequency and energy of electromagnetic radiations decreases. The longest wave is radio waves.Shortest wave is gamma rays.
The given image of wave is from longer wavelength to shorter wavelength hence the radiations can be arranged as : Radio waves , microwave, infrared, visible light, ultraviolet, X-rays and gamma rays.

4 NH3 + 5 O2 - 4 NO + 6 H20
Given 20 moles of O2 and 14 moles of NH3, which would act as the limiting reactant?
NH₃ as the limiting reactant
Further explanationGiven
Reaction
4 NH3 + 5 O2 ⇒ 4 NO + 6 H20
Required
The limiting reactant
Solution
To find the limiting of the reactants, we can use the method by dividing the moles of each reactant by the reaction coefficient. The smallest ratio will be the limiting reactants
the mol ratio of NH₃ : O₂ =
=14/4 : 20/5
= 3.5 : 4
So NH₃ as the limiting reactant
does energy transfer always result in phase change
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance.

all the drop boxes say compound & element. pick either or for each one.
Answer:
Hydrogen = element
Carbon dioxide = compound
Water = compound
Zinc = element
Nitrogen = element
Salt = compound
Helium = element
Carbon monoxide = compound
Explanation:
An element and a compound are different when it comes to the types of atoms they possess. An element has only one type of atom while a compound has two types of atoms. For example, Hydrogen is an element because it has two atoms of the same type and that is, the "Hydrogen atom."
On the contrary, Carbon dioxide has one carbon atom and two atoms for Oxygen. Therefore, it is a compound because it has two types of atoms: Carbon atom and Oxygen atom.
Water has two atoms of Hydrogen and one atom of Oxygen. Therefore, it is a compound because it has two types of atoms: Hydrogen atom and Oxygen atom.
