Which mass is made up of 6.02x10^23 atoms? none of these 23 g sodium 42 g krypton 24 g carbon 78 g potassium
Answers
Answer:
23 g sodium
Explanation:
In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).
According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23
Using the formula; mole = mass/molar mass
- Sodium = 23g/23g/mol = 1mol
- Krypton = 42g/84g/mol = 0.5mol
- Carbon = 24g/12g/mol = 2mol
- Pottasium = 78g/39g/mol = 2mol
Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

1. A student predicted the reaction between hydrogen and oxygen gas would yield 125
mL of water. However, after measuring the water formed in the reaction, the
student determined that only 110mL of water was actually formed. What is the
percent yield of this reaction?
Answers
Answer:
88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88
0.88 x 100 = 88%

Will there ever be grams of a limiting reactant remaining after a reaction has stopped? Why or why not?
Answers
Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

Which of these layers is found directly above the Earth's core?
Group of answer choices
Outer core
Mantle
Inner core
Crust
Answers
Answer: Mantle
Explanation:
there are 3 layers of the earth- core, mantle and crust. The layer found directly above the earth's core is the mantle.
Answer:
The answer depends on what you are taking about: the outer core or the inner core?
Answer: Mantle
Explanation:
If you find a picture of the Earth's layers, you can see that the inner core is the bottommost layer. However, if you combine the Inner Core and Outer Core, that could be determined as the Earth's core.
I would chose the Mantle because if the two cores are combined, the layer directly above them is the Mantle.
How did mitochondria
become part of the cell?
Answers
Answer: The mitochondria, as bacteria, only wanted to rob the host cells of their energy and then leave them to die. But the bacteria soon realized the benefit of working together with simple cells. The simple cells provide them with antioxidants to protect them from free radicals and toxic reactive oxygen species that the mitochondria generate as a byproduct of energy production.

89. What is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C?
Answers
0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.
What is an ideal gas equation?The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
According to Ideal Gas Equation,
PV = nRT
Therefore, P ∝ T
P₁T₂ = P₂T₁
Given :
P₁ = ?
P₂ = 1.11 atm
T₁ = 30.0 C
T₂ = 15 C
Solving :
P₁ x 30 = 1.11 x 15
P₂ = 0.555 atm
Hence, 0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.
