According to Le Châtelier's principle, how will an increase in pressure affect a gaseous equilibrium system? O Shift it toward the products O Shift it toward the reactants Shift it toward the side with higher total mole concentration O Shift it toward the side with lower total mole concentration​

Answers

Answer 1

Answer:

Shift it toward the side with lower total mole concentration

Explanation:

The reaction will shift in a direction that is less affected by stress, so that the pressure is reduced. This means that the reaction will change towards where there is fewer gas molecules (the fewer gas molecules, the smaller the pressure).

Answer 2

Answer:

A. Shift it toward the side with lower total mole concentration

Explanation:

calculate the maximum mass of ethanol that could be obtained from 30.0g of glucose​

Answers

Answer:

15.3g

Explanation:

C6H12O6 → 2C2H5OH + 2CO2

1 mol C6H12O6 = 180g

1 mol CH3-CH2-OH = 46g

From 180g glucose ethanol can get = 92g

30g glucose ethanol gives us = (92*30)/180 = 15.33g

What mass of helium gas (in g) occupies 15.3 L at STP?

Answers

Answer:

[tex]\boxed {\boxed {\sf 2.73 \ g \ He}}[/tex]

Explanation:

We are asked to find the mass of helium gas given a volume.

1. Convert Liters to Moles

1 mole of any gas occupies a volume of 22.4 liters. So, 1 mole of helium gas contains 22.4 liters of helium. Create a ratio using this information.

[tex]\frac {1 \ mol \ He }{ 22.4 \ L \ He}[/tex]

We are converting 15.3 liters of gas to moles, so we multiply by that value.

[tex]15.3 \ L \ He *\frac {1 \ mol \ He }{ 22.4 \ L \ He}[/tex]

The units of liters of helium (L He) cancel.

[tex]15.3 *\frac {1 \ mol \ He }{ 22.4}[/tex]

[tex]\frac {15.3}{22.4} \ mol \ He[/tex]

[tex]0.6830357143 \ mol \ He[/tex]

2. Convert Moles to Grams

The molar mass is the mass of 1 mole of a substance. These values are found on the Periodic Table as atomic masses, but the units are grams per moles. Look up the molar mass of helium.

He: 4.0026 g/mol

Create another ratio using the molar mass.

[tex]\frac {4.0026 \ g \ He}{1 \ mol \ He}[/tex]

Multiply by the number of moles we calculated.

[tex]0.6830357143 \ mol \ He *\frac {4.0026 \ g \ He}{1 \ mol \ He}[/tex]

The units of moles of helium (mol He) cancel.

[tex]0.6830357143*\frac {4.0026 \ g \ He}{1 }[/tex]

[tex]2.73391875 \ g \ He[/tex]

3. Round

The original measurement of volume has 3 significant figures, so our answer must have the same.

For the number we calculated, that is the hundredths place.

The 3 in the thousandths place to the right (2.73391875) tells us to leave the 3 in the hundredths place (2.73391875).

[tex]2.73 \ g \ He[/tex]

15.3 liters of helium gas is approximately 2.73 grams of helium.

Explain how the existence of ions relates to the number of electrons present in atoms of an element? (A.P.E.X)

Answers

Answer:

if you have options please include them, but I'll give you an idea.

Explanation:

The existence of ions happens when atoms lose or gain electrons.

if an atom gains an electron it will become a negative ion (because electrons are negative, and you gained more negativity.)

if an atom loses an electron it will become a positive ion (because it has lost negativity, which is the electron that we've lost).

a 20.5g sample of cleaning detergent contains 8.61g of NH40H.CALCULATE the percentage composition of nitrogen in the cleaning detergent sample​

Answers

Answer:

The mass percentage composition of nitrogen in the sample of the cleaning detergent is approximately 16.78%  

Explanation:

The given mass of the sample of the cleaning detergent, m₁ = 20.5 g

The mass of the ammonium hydroxide, NH₄OH in the detergent, m₂ = 8.61 g

The molar mass of NH₄OH = 35.04 g/mol

The molar mass of nitrogen, N = 14.01 g/mol

Therefore, the mass, m₃ of nitrogen, N, in 8.61 g of ammonium hydroxide, NH₄OH, is found as follows;

m₃ = (14.01/35.04) × 8.61 g = (402,087/118,800) g ≈ 3.44 g

The mass of nitrogen, N, in the ammonium hydroxide, NH₄OH, contained in the 20.5 g sample of the cleaning agent, m₃ ≈ 3.44 grams

The percentage composition of nitrogen in the sample of the cleaning detergent, %N is given as follows;

[tex]\% Composition = \dfrac{Mass \ of \ component}{Total \ mass \ of \ cleaning \ detergent} \times 100[/tex]

Therefore;

%N ≈ ((3.44 g)/(20.5 g)) × 100 ≈ 16.78 %

The percentage composition of nitrogen, %N ≈ 16.78%.

Which element will form In ion whose lonic radius is larger than its atomic radius?
(1) K
(2) F
(3) LI
(4) Mg

Answers

Answer:

Letter b so F

Explanation:

I hope this help

Explanation:

All five ions have an equal number of electrons and therefore share the same electron configuration. For example, a neutral calcium atom (Z=20) has 20 electrons; it loses two of them to form a Ca2+ cation, which would thus contain 20−2=18 electrons. Similarly, a phosphorus atom (Z=15) gains three electrons to form a P3− anion that contains 15+3=18 electrons.

Positively-charged protons in the nuclei attract the negatively-charged electron cloud. Each proton carries a +1 charge; the more protons an atom or ion contains the stronger the attraction it poses on its electron cloud. A nucleus of strong positive charge pulls its electron cloud towards itself tightly such that the latter would have a small radius.

The periodic table is arranged in the order of increasing proton number. Phosphorus comes the first among the five species and contains the least number of protons. Its ion would be the largest among the five. Calcium comes the last and forms the smallest ion.

Number of protons per nucleus P<S<Cl<K<CaStrength of Electrostatic attraction on the electron cloud P<S<Cl<K<CaIonic radius P3−>S2−>Cl−>K+>Ca2+
