Explanation:
The limiting reagent and the number of S'mores produced for each of the reactions is given below:
Reaction 1. The limiting reagent is Cp; 1.6 S'mores are produced.
Reaction 2. The limiting reagent is M;2 S'mores are produced.
Reaction 3. The limiting reagent is Gc; 2.5 S'mores are produced.
Reaction 4. The limiting reagent is M;1 S'more is produced.
The equation of the reaction shows the stoichiometry between reactants and products.
For the given reaction, the equation of reaction is as follows:
1M + 2Gc + 3Cp ----> 1Gc2MCp3
where:
From the equation of reaction:
The stoichiometric equation is: 2Gc + 1M + 3Cp ----> 1Gc2MCp3
The ratio of Gc to M to Cp is 2 : 1 : 3
Reaction 1. 4 Gc + 2M + 5 Cp
The ratio of Gc to M to Cp in the reaction above is 2 : 1 : 2.5
3 Cp makes 1 S'more
5 Cp will make 5 * 1/3 S'more = 1.6 S'mores
Reaction 2. 6 Gc + 2M + 9 Cp
The ratio of Gc to M to Cp in the reaction above is 3 : 1 : 4.5
1 M makes 1 S'more
2 Cp will make 2 * 1/1 S'more = 2 S'mores
Reaction 3. 5 Gc + 3M + 9 Cp
The ratio of Gc to M to Cp in the reaction above is 1.6 : 1 : 3
2 Gc makes 1 S'more
5 Gc will make 5 * 1/2 S'more = 2.5 S'mores
Reaction 4. 7 Gc + 1M + 6 Cp
The ratio of Gc to M to Cp in the reaction above is 7 : 1 : 6
Therefore the limiting reagent is M
1 M makes 1 S'more
The limiting reagent and the number of S'mores produced for each of the reactions is given below:
1. The limiting reagent is Cp; 1.6 S'mores are produced.
2. The limiting reagent is M;2 S'mores are produced.
3. The limiting reagent is Gc; 2.5 S'mores are produced.
4. The limiting reagent is M;1 S'more is produced.

cytoplasm by____
Answer:
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Hope This helps if not Then im Sorry XD
The best example of natural plasma is the ionosphere of the atmosphere including solar corona and lightning including auroras cloud.
the heated or hot matter that is so hot that the electrons are thrown away from the atoms and forms the ionized gas. Comprises over 99% of the visible universe.
Lightning strikes create plasma by doing a stricking of electricity. Mostly the Sun, and some stars, are in a plasma state. Certain regions of Earth's atmosphere contain some plasma created primarily by ultraviolet radiation from the Sun.
One reason plasma is not so common is because this needs high temperatures required to keep gas in the plasma state. At average temperatures on Earth, there just isn't enough energy for atoms to remain ionized.
However, at thousands to millions of degrees Kelvin, these energies are available, and plasmas dominate
Therefore, aurora clouds are natural plasma.

aurorus
Explanation:
Answer: 22.8atm
Explanation:
T1 = —13°C = —13 +273 = 260K
T2 = 24°C = 24 +273 = 297K
V1 = V
V2 = 35% of V= 0.35V
P1 = 7atm
P2 =?
P1V1/T1 = P2V2 /T2
(7 x V)/260 = (P2 x 0.35V)/297
P2x0.35Vx260 = 7V x 297
P2 x 91V = 2079V
P2 = 2079V / 91V
P2 = 22.8atm
A reaction mixture initially contains a Br2 partial pressure of 751 torr and a Cl2 partial pressure of 737 torr at 150 K.
Calculate the equilibrium partial pressure of BrCl.
Answer:
the equilibrium partial pressure of BrCl is pBC = 784.52 torr
Explanation:
Since
Br₂(g) + Cl₂(g) ⇌ 2BrCl(g) , Kp=1.112 at 150 K
denoting BC as BrCl , B as Br₂ , C as Cl₂, p as partial pressure , then
Kp = pBC²/[pB*pC]
solving for pBC
pBC = √(Kp*pB*pC)
replacing values
pBC = √(Kp*pB*pC) = √(1.112*751 torr*737 torr) = 784.52 torr
pBC = 784.52 torr
then the equilibrium partial pressure of BrCl is pBC = 784.52 torr
To calculate the equilibrium partial pressure of BrCl, use the equilibrium constant expression and substitute the given partial pressures of Br2 and Cl2. The equilibrium partial pressure of BrCl is approximately 0.0375 atm.
To calculate the equilibrium partial pressure of BrCl, we need to use the equilibrium constant expression:
Kp = ([BrCl]^2) / ([Br2] * [Cl2])
Given that the equilibrium partial pressures of Br2 and Cl2 are 0.450 atm and 0.115 atm, respectively, we can substitute these values into the expression:
1.112 = ([BrCl]^2) / (0.450 * 0.115)
Simplifying the expression, we find that the equilibrium partial pressure of BrCl is approximately 0.0375 atm.
