If the pressure in a gas container that is connected to an open-end U-tube manometer is 116 kPa and the pressure of the atmosphere at the open end of the tube is 752 mm Hg, the level of mercury in the tube will
Answer:
The level of mercury in the tube will be 118 mmHg
Explanation:
As per the given data
Pressure of container = P1 = 116 kPa
Pressure of atmosphere = P2 = 752 mmHg
First, we need to convert the pressure of the container in mmHg as follow
P1 = 116 kPa x [tex]\frac{1 atm}{101.325 kPa}[/tex] x [tex]\frac{760 mmHg}{1 atm}[/tex] = 870 mmHg
Hence the pressure in the container is higher than the pressure of the atmosphere and the mercury level will increase.
Now calculate the level of mercury in the tube as follow
Level of Mercury = Pressure of container - Pressure of atmosphere
P = P1 - P2
P = 870 mmHg - 752 mmHg
P = 118 mmHg

Be sure your answer has the correct number of significant digits.
Answer:
3.10 × 10⁻⁴ mg
Explanation:
In the Minnesota Department of Health set a health risk limit for benzene in groundwater of 10.0 μg/L. Suppose an analytical chemist receives a sample of groundwater with a measured volume of 31.0 mL. Calculate the maximum mass in milligrams of benzene which the chemist could measure in this sample and still certify that the groundwater from which it came met Minnesota Department of Health standards. Be sure your answer has the correct number of significant digits.
Step 1: Given data
Concentration limit (C): 10.0 μg/LVolume of the sample (V): 31.0 mLStep 2: Convert "V" to L
We will use the conversion factor 1 L = 1000 mL.
31.0 mL × 1 L/1000 mL = 0.0310 L
Step 3: Calculate the maximum mass of benzene (m)
We will use the following expression.
m = C × V = 10.0 μg/L × 0.0310 L = 0.310 μg.
Step 4: Convert "m" to mg
We will use the conversion factor 1 mg = 1000 μg.
0.310 μg × 1 mg/1000 μg = 3.10 × 10⁻⁴ mg

Write the molecular formula for a compound with the possible elements C, H, N and O that exhibits a molecular ion at M
Answer:
[tex]= \mathbf{C_3H_6O}[/tex]
Explanation:
From the given information, since the molecular mass of the ion M+ is not given;
Let's assume M+ = 58.0423
So, by applying the 13th rule;
we will need to divide the mass by 13, after dividing it;
The quotient n = no. of carbon; &
The addition of the quotient (n) with the remainder r = no. of hydrogen.
So;
[tex]\dfrac{58}{13}= 4 \ remainder \ 6[/tex]
So;
[tex]C_nH_{n+r} = C_4H_{4+6}[/tex]
[tex]= C_4H_{10}[/tex]
From the given information; we have oxygen present, so since the mass of oxygen = 16, we put oxygen in the molecular formula by removing [tex]CH_4[/tex]. Also, since the mass is an even number then Nitrogen is 0.
So, we have:

Explanation:
Rank the nonmetals in each set from most reactive (1) to least reactive (3).
Bromine: ?
Chlorine: ?
Iodine: ?
Answer:
Chlorine Bromine IodineExplanation:
All three of these elements fall in group 7 of the periodic table and are called Halogens. Chlorine is the most reactive of these elements because it comes before the other two in the table then followed by Bromine and then Iodine.
Reactivity decreases in the group 7 elements as one moves to the latter elements due to the increase in shells surrounding the nucleus.
This is because reactivity happens as the protons in the nucleus attract electrons but when more shells are piled on, the strength of this attraction decreases as the distance increases such that they will not be as reactive anymore.

what is the boiling point of water at the top of mount everest where the atmospheric pressure is only 34% as strong
This question is incomplete, the complete is;
Water has a heat of vaporization (ΔHvap) of 44.01 kJ mol-1 and boils at 100 degrees C at sea level.
What is the boiling point of water at the top of Mount Everest where the atmospheric pressure is only 34% as strong as the pressure at sea level?
Answer: the boiling point of water at the top of mount Everest where the atmospheric pressure is only 34% as strong is 74 °C
Explanation:
Given that;
P1 = 1 atm,
T1 = 100°C = 373 K
P2 = P1 × 34% = 1×0.34 = 0.34 atm
T1 = ?
ΔH = 44.01 kJ mol⁻¹ = 44.01×10³ J/mol
R = 8.314 J/k.mol
now using the Clausius - Clapeyron equation;
p1_∫^p2 d.InP = ΔHvap/R T1_∫^T2. 1/T².dT
⇒ In(P2/P1) = ΔHvap/R (1/T1 - 1/T2)
so we substitute;
ln( 0.34/1 ) = ( 44.01×10³ / 8.314) × ( 1/373 - 1/T2)
-1.0788 = 5293.4808 × ( 0.00268 - 1/T2)
-1.0788 = 14.1865 - 5293.4808(1/T2)
5293.4808(1/T2) = 14.1865 + 1.0788
5293.4808(1/T2) = 15.2653
(1/T2) = 15.2653 / 5293.4808
(1/T2) = 0.0028837
T2 = 1 / 0.0028837
T2 = 346.8 K
WE convert to Celsius
t2 =346.8 K − 273.15 = 73.65 °C ≈ 74 °C
Therefore, the boiling point of water at the top of mount Everest where the atmospheric pressure is only 34% as strong is 74 °C

[tex]T = \frac{2.14 \ \times \ 3.45}{0.461 \ \times \ 0.08205} \\\\T = 195.2 \ K[/tex]
Therefore, the temperature of gas inside the container is 195.2 K.
4.00 g of a certain Compound X, known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of 152. gimol, is burned completely in excess oxygen, and the mass of the products carefully measured:
product mass
carbon dioxide 5.79 g
water 2.84 g
Use this information to find the molecular formula of X.
Answer:
C₄H₁₀O₄
Explanation:
From the question given above, the following data were obtained:
Mass of compound = 4 g
Molar mass of compound = 152 g/mol
Mass of CO₂ = 5.79 g
Mass of H₂O = 2.84 g
Molecular formula of compound X =?
Next, we shall determine the mass of Carbon, Hydrogen and Oxygen in the compound. This can be obtained as follow:
For Carbon (C):
Mass of CO₂ = 5.79 g
Molar mass of CO₂ = 12 + (2×16) = 44 g/mol
Mass of C = 12/44 × 5.79
Mass of C = 1.58 g
For Hydrogen (H):
Mass of H₂O = 2.84 g
Molar mass of H₂O = (2×1) + 16 = 18 g/mol
Mass of H = 2/18 × 2.84
Mass of H = 0.32 g
For Oxygen (O):
Mass of C = 1.58 g
Mass of H = 0.32 g
Mass of compound = 4 g
Mass of O =?
Mass of O = (Mass of compound) – (Mass of C + Mass of H)
Mass of O = 4 – (1.58 + 0.32)
Mass of O = 4 – 1.9
Mass of O = 2.1 g
Next, we shall determine the empirical for compound X. This can be obtained as follow:
C = 1.58 g
H = 0.32 g
O = 2.1 g
Divide by their molar mass
C = 1.58 / 12 = 0.13
H = 0.32 / 1 = 0.32
O = 2.1 / 16 = 0.13
Divide by the smallest
C = 0.13 / 0.13 = 1
H = 0.32 / 0.13 = 2.46
O = 0.131 / 0.13 = 1
Multiply by 2 to express in whole number
C = 1 × 2 = 2
H = 2.46 × 2 = 5
O = 1 × 2 = 2
Thus, the empirical formula for the compound is C₂H₅O₂
Finally, we shall determine the molecular formula for the compound. This can be obtained as follow:
Molar mass of compound = 152 g/mol
Empirical formula => C₂H₅O₂
Molecular formula =?
Molecular formula => [C₂H₅O₂]ₙ
[C₂H₅O₂]ₙ = 152
[(2×12) + (5×1) + (2×16)]n = 152
[24 + 5 + 32]n = 152
61n = 152
Divide both side by 61
n = 152 / 61
n = 2
Molecular formula => [C₂H₅O₂]₂
Molecular formula => C₄H₁₀O₄

Animals that rely on plants to transform chemical energy into carbohydrates and sugars are
A. primary producers.
B. first level consumers.
C. second level consumers.
D. detritivores,
Answer:
B. first level consumers.
Explanation:
The first level consumers are also the primary consumers. They are the animals that depends or rely on plants to transform chemical energy into carbohydrates and sugar.
Primary consumers are mostly herbivores. They feed on plant matter by which they derive their nutrition. They have special enzymes that helps to convert plant materials into substances needed for their body.
So, the first level consumer takes plant matter and convert them into useful food materials for their own nutrition.
The second level consumers depend on the first level consumers for nutrition.

ANSWER
Selenium has 34 protons
A sample of an unknown compound is vaporized at 150.°C . The gas produced has a volume of 960.mL at a pressure of 1.00atm , and it weighs 0.941g . Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound.
Answer:
34.02 g.
Explanation:
Hello!
In this case, since the gas behaves ideally, we can use the following equation to compute the moles at the specified conditions:
[tex]PV=nRT\\\\n=\frac{1.00atm*0.960L}{0.08206\frac{atm*L}{mol*K}*(150+273)K} =0.0277mol\\\\[/tex]
Now, since the molar mass of a compound is computed by dividing the mass over mass, we obtain the following molar mass:
[tex]MM=\frac{0.941g}{0.0277mol} \\\\MM=34.02g/mol[/tex]
So probably, the gas may be H₂S.
