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).

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%.

For his science fair project, Martin studied the growth of trumpet vines. He grew 20 trumpet vines. All of the conditions were the same, except that he grew 10 in a flower bed without support and 10 in a flower bed near a trellis. The stems of the vines near the trellis twisted around the trellis, and these Yines grew tall and seemed much healthier than the vines grown without a trellis. In fact, four of the vines grown without a trellis died. Which characteristic of living things were the trumpet vines displaying as the stems twisted around the trellis?

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+

Which factors ALL increase reaction rate?


decrease temperature, stir, increase surface area, remove catalyst

none of these

increase temperature, increase surface area, add catalyst, stir

increase temperature, stir, decrease surface area, add catalyst

Answers

Answer:

increase temperature, increase surface areas, add catalyst, stir

The rate of reaction can be increased with the increase in temperature, surface area, adding catalyst and allowing stirring. Thus, option C is correct.

What is rate of reaction?

The rate of reaction is given as the rate of formation of product or the rate of disappearance of reactant in unit time.

The rate of reaction can be affected with:

Increase in temperature - It will increase the collisions between the reactants, and thereby the rate.

Increase in surface area - It results in increased interaction of the reactant molecules for the formation of product.

Catalyst - It lowers the activation energy of the reactant, and thereby increases the rate of reaction.

Stirring - It mediates the increase in the collisions and the surface area, and resulting in increased rate of reaction.

Thus, the rate of reaction can be increased with the increase in temperature, surface area, adding catalyst and allowing stirring. Thus, option C is correct.

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).
