How many liters of ammonia are formed with 49.8 g of nitrogen gas reacting with 10.7 g of hydrogen gas at S.T.P.?
Answers
N2+3H2---->2NH3
the number of moles of N2 is 49.8g/14gmol^-1=3.56mol
the number of moles of H2 is 10.7g/2gmol^-1=5.35mol
here, since the ratio of N2/H2 is 1/3, we can see that H2 is the limiting reagent. therefore, the reaction proceeds as follows:
N2 + 3H2 ---------------> 2NH3
5.36mol (2/3)(5.36mol)=3.57mol
therefore, the number of moles of ammonia formed is 3.57mol. at STP, P=1atm, T=273K.
Therefore, V(NH3)=(3.57)(22.38)=79.822 L
How can air quality be fine on one day and hazardous on the next? What
are some things that can cause a rapid change in air quality? *
Answers
Answer:
Air Current
Explanation:
Say I am in California and there is a massive fire next to me but not close enough to me to really see the fire and the next day I see no fire but theres a ton of ash in the sky, this can be due to the wind current taking the smoke from the fire into my direction and that smoke falling in my area. So basically a wind current can take the smoke from a fire into another destination and cause a rapid change in air quality in a day.
At 303 K, the volume of a gas is 30.0 ml. At constant pressure, what is the new
volume of the gas if the temperature is decreased to 283K?
Answers
Answer:
V₂ = 28 mL
Explanation:
Given data:
Initial temperature = 303 K
Initial volume = 30.0 mL
Final temperature = 283 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 30.0 mL × 283 K /303 K
V₂ = 8490 mL.K / 303 K
V₂ = 28 mL

How many moles are there in a 122 gram sample of nickel (Ni)?
7.16 x 103 moles
6.22 mol
2.08 mol
0.481 mol
Answers
The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.
Nickel:
The atomic number of nickel is 28.The symbol of nickel is Ni.Density of a nickel 8.908 g/cm3.It is a d block element.It belongs to group 10 and period 4.It is also called transition metal.It is a metal and is located between groups 2 and 3.Mass of nickel given: 122 grams.
Atomic mass of nickel: 58.71 g mol
Number of moles = Mass / molar mass
= 122/ 58.71
= 2.078
= 2.08 moles.
The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

Answers
Answer:
ions
Explanation:
Individual atoms of the same element but having slightly different number of protons and electrons are called ions.
Ion is a charged particle.
An atom is made up of three fundamental subatomic particles. Protons are the positively charged particles Electrons are the negatively charged particles Neutrons do not carry any charges.When the number of protons > electrons the body is positively charged.
When the number of electrons > protons the body is negatively charged.
Charged particles are called ions.

A very hot cube of copper metal (32.5 g) is submerged into 105.3 g of water at 15.4 0C and it reach a thermal equilibrium of 17.3 0 Calculate the initial temperature of copper (Cs = 0.385 J/g 0C for copper, and 4.18 J/g 0C for water).
Answers
Answer:
The initial temperature of the metal is 84.149 °C.
Explanation:
The heat lost by the metal will be equivalent to the heat gain by the water.
- (msΔT)metal = (msΔT)water
-32.5 grams × 0.365 J/g°C × ΔT = 105.3 grams × 4.18 J/g °C × (17.3 -15.4)°C
-ΔT = 836.29/12.51 °C
-ΔT = 66.89 °C
-(T final - T initial) = 66.89 °C
T initial = 66.89 °C + T final
T initial = 66.89 °C + 17.3 °C
T initial = 84.149 °C.
