a gas mixture containing hydrogen, oxygen, and nitrogen has a total pressure of 840 torr. if p hydrogen = 320 torr and p oxygen = 485 torr, what is the partial pressure of nitrogen in the mixture? please help
Answer
35 torr
Explanation:
The mixture contains 320 torr of hydrogen, 485 torr of oxygen, a total pressure of 840 torr, so you need to find the leftover
320(hydrogen) + 485(oxygen) = 805 torr
840(total) - 805 = 35 torr

how are molarity and volume related
these are the options
A They are directly related.
B They are inversely related.
C They are different units of dilution.
D They are different units of concentration.
Answer:
Molarity can be used to calculate the volume of solvent or the amount of solute. The relationship between two solutions with the same amount of moles of solute can be represented by the formula c1V1 = c2V2, where c is concentration and V is volume.
The relationship between Molarity and volume of a solution is : ( B ) They are inversely related
What is molarity ?Molarity is the number of moles of solute in unit of volume of the solution ( usually per liter ). Molarity is calculated by dividing the number of moles of a solute ( n ) by the volume of the solution.
Molarity = n / v .
Therefore we can conclude that the relationship between Molarity and volume is that they are inversely related.

How many grams H2 are needed to react with 2.80 g of N2?
Answer:
N2 +3 H2 → 2 NH3
so we have 2180 g of N2
or 2.80 g ÷ 28.02 g/mol = 0.100 mol
1 mol of N2 react with 3 moles of H2
Therefore 0.100 mol of N2 react with 0.3 moles of H2
0.300 mol X Molar mass (2.00 g/mol) = 0.600 g
0.600 g of H[tex]_2[/tex] are needed to react with 2.80 g of N[tex]_2[/tex]. Mole is one of the International System for Units' seven foundation units (SI).
What is mole?A mole is just a measuring scale. In reality, it is one of the International System for Units' seven foundation units (SI). When already-existing units are insufficient, new ones are created. Using absolute amounts of atoms, molecules, or ions would be problematic as well since chemical reactions frequently occur at levels that use grams would be inappropriate.
A mole consists of precisely 6.022140761023 particles. The "particles" might be anything, from tiny things like electrons and atoms to enormous things like stars or elephants.
N[tex]_2[/tex] +3 H[tex]_2[/tex] → 2 NH[tex]_3[/tex]
2.80 g ÷ 28.02 g/mol = 0.100 mol of N[tex]_2[/tex]
1 mol of N[tex]_2[/tex] react with 3 moles of H[tex]_2[/tex]
0.100 mol of N[tex]_2[/tex] react with 0.3 moles of H[tex]_2[/tex]
0.300 mol X Molar mass (2.00 g/mol) = 0.600 g of H[tex]_2[/tex]
Therefore, 0.600 g of H[tex]_2[/tex] are needed to react with 2.80 g of N[tex]_2[/tex].

How many molecules are in 4 moles of carbon monoxide (CO)?
Select one:
a. 2.41x1024 CO molecules
b. 24.1x1023 CO molecules
c. 6.64x1024 CO molecules
d. 1.51x1023 CO molecules
Answer:
A
Explanation:
because number of particle = moles × 6.02 × 10^23
which gives the answer as an A
2.41x10²⁴ molecules are in 4 moles of carbon monoxide (CO). Therefore, the correct option is option A.
What is molecule?The smallest recognizable unit into that a pure substance may be divided while retaining its composition as well as chemical properties is a molecule, which is a collection of atoms that are at least two in number. Until parts made up of a single molecule are reached, the division of an example of a substance smaller progressively smaller parts does not result in a change with regard to its composition nor its chemical properties.
Still smaller sections of the substance are produced by further subdivision, and these components are always different chemically and typically have different compositions from the initial substance. The chemical links that link the atoms in the molecule together are severed during this final step of fragmentation.
molecules = moles × 6.022×10²³
= 2.41x10²⁴
Therefore, the correct option is option A.

If 11 kJ of heat is transferred to 2300 g of soil at 21°C, what would the new temperature of the soil be?
Answer:
26.98°C
Explanation:
Applying,
Q = cm(t₂-t₁)................ Equation 1
Where Q = Heat transferred to the soil, c = specific heat capacity of dry soil, m = mass of the soil, t₂ = final temperature, t₁ = initial temperature.
From the question,
Given: Q = 11 kJ = 11000 J, m = 2300 g = 2.3 kg, t₁ = 21°C
Constant: c = 800 J/kg.°C
Substitute these values into equation 1
11000 = 800×2.3(t₂-21)
Solving for t₂
t₂-21 = 11000/(800×2.3)
t₂-21 = 11000/1840
t₂-21 = 5.98
t₂ = 5.98+21
t₂ = 26.98°C
How many molecules of HCl are needed to react with 1.7 moles of magnesium. The products of
the reaction are magnesium chloride and hydrogen gas.
2HCl + Mg --> MgCl2 + H2
(pls help)
Answer:
2.05 x 10²⁴ molecules
Explanation:
The balanced equation for the chemical reaction is the following:
2 HCl + Mg → MgCl₂ + H₂
According to the equation, 2 moles of HCl are required to react with 1 mol of magnesium (Mg), so the moles of HCl required to react with 1.7 mol Mg are calculated as follows:
moles HCl = 1.7 mol Mg x 2 mol HCl/mol Mg = 3.4 mol HCl
We know that 1 mol of any compound is equal to 6.022 x 10²³ molecular entities, so we convert the moles of HCl to molecules as follows:
molecules HCl = 3.4 mol HCl x 6.022 x 10²³ molecules/1 mol = 2.05 x 10²⁴ molecules
