Al + AgNO3 -> Al(NO3)3 + Ag. As a balanced equation​

Answers

Answer 1

Answer:

Al + 4AgNO3 >>Al(NO3)3+ 3Ag

Explanation:

the number of moles of No3 of the products is 3 therefore we have to balance the reactants by adding 3 before the "AgNO3" which also leades us to adding 3 mols to Ag on the products side

A solution contains 2.38 g of magnesium chloride, MgCl, in 500 cm3 of solution
What is the concentration of
chloride ions in g/dm3?​​

Answers

Answer:

3.54g Cl-/dm³

Explanation:

To solve this question we must, as first, find the mass of chloride ions finding first, the moles of MgCl2. Then, we must convert the cm³ to dm³ (1cm³ = 0.001dm³).

Moles MgCl2 -Molar mass: 95.211g/mol-

2.38g * (1mol / 95.211g) = 0.0250 moles MgCl2

Moles Cl-:

0.0250 moles MgCl2 * (2mol Cl- / 1mol MgCl2) = 0.0500 moles Cl-

Mass Cl- -Molar mass: 35.45g/mol-:

0.0500 moles Cl- * (35.45g / mol) = 1.77g of chloride ions

dm³:

500cm³ * (0.001dm³ / 1cm³) = 0.500dm³

The concentration is:

1.77g of chloride ions / 0.500dm³ =

3.54g Cl-/dm³

Earth's surface is shaped and changed in many ways. Which of these can shape Earth's surface?

water

wind

ice

gravity

organisms (living things)

the sun

none of these

all of the above

Answers

Answer: All of the above!

Explanation:
Water- moves across soil and breaks down pieces of rocks
Wind- can blow materials around, such as rocks or sand. Also it can dry out soil.
Ice- carries broken rocks or soil to different places and can cause glacier erosion.
Gravity- thinking about it, earth is the one place with gravity so if gravity changed it can cause objects to move. Also it determines the shape of the earth because the center has more gravitational pull. This gives it a very round shape.
Organisms- more animals means increase of destruction of plants, which can lead to faster erosion.
Sun- the sun is very important. If the earth didn’t get any sunlight there wouldn’t be any life on the planet itself. Which makes it lack rocks, plants, weather, and the atmosphere.
And by that point it’s just not none of the above.

Que cantidad de solvente se necesita para obtener una solucion al 20% cuando se mezclan 600mg de alcohol.

Answers

Answer:

[tex]m_{solvente}=2400mg[/tex]

Explanation:

¡Hola!

En este caso, con la información dada, es posible inferir que este problema es acerca del porcentaje en masa del soluto y que se calcula de la siguiente manera, en términos de la masa de soluto y solución:

[tex]\% m=\frac{m_{soluto}}{m_{solucion}} *100\%[/tex]

De este modo, como conocemos el porcentage y la masa del soluto, podemos calcular la masa de la solución primero:

[tex]m_{solucion}=\frac{m_{soluto}}{\% m} *100\%\\\\m_{solucion}=\frac{600mg}{20\%} *100\%\\\\m_{solucion}=3000mg[/tex]

Esto quiere decir que la masa del solvente es:

[tex]m_{solvente}=m_{solucion}-m_{soluto}\\\\m_{solvente}=3000mg-600mg\\\\m_{solvente}=2400mg[/tex]

Hospital patients are administered oxygen from an pressurized
hyperbaric oxygen chamber. 600.0 L of oxygen is compressed in a
cylinder at 160.0 atm. What volume of oxygen can a cylinder supply at a
pressure of 3.0 atm?

Answers

Answer:

32000atm

Explanation:

Using Boyle's law equation;

P1V1 = P2V2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (

V2 = final volume (L)

According to the question below:

P1 = 160.0 atm

P2 = 3.0 atm

V1 = 600L

V2 = ?

Using P1V1 = P2V2

160 × 600 = 3 × V2

96000 = 3V2

V2 = 96000/3

V2 = 32000atm

Answers

If you produce 35.7 grams of sodium chloride how many molecules of Chlorine gas were
needed?
2Na + Cl2 --> 2NaCl
(PLS HELP)

Answers

Answer: [tex]7.36\times 10^{23}[/tex] number of molecules of chlorine gas are needed.

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)

Given mass of sodium chloride = 35.7 g

Molar mass of sodium chloride = 58.44 g/mol

Plugging values in equation 1:

[tex]\text{Moles of sodium chloride}=\frac{35.7g}{58.44g/mol}=0.611 mol[/tex]

The given chemical equation follows:

[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]

By the stoichiometry of the reaction:

If 1 mole of sodium chloride is produced from 2 moles of chlorine gas

So, 0.611 moles of sodium chloride will be produced from = [tex]\frac{2}{1}\times 0.611=1.222mol[/tex] of chlorine gas

According to the mole concept:

1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of molecules

So, 1.222 moles of chlorine gas will contain = [tex]\frac{6.022\times 10^{23}}{1mol}\times 1.222mol=7.36\times 10^{23}[/tex] number of molecules

Hence, [tex]7.36\times 10^{23}[/tex] number of molecules of chlorine gas is needed.

A mixture of He, Ne, and N2 gases has a pressure of 1.943 atm. If the pressures of He and Ne are 0.137 atm and 0.566 atm, respectively, what is the partial pressure of N2 in the mixture?  A. 0.703 atm  B. 1.24 atm  C. 0.151 atm  D. 1.943 atm

Answers

Answer:

The parcial pressure of N₂ in the mixture is 1.24 atm.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

In this case:

PT=PHe + PNe + PN₂

You know:

PT= 1.943 atmPHe= 0.137 atmPNe= 0.566 atmPN₂= ?

Replacing:

1.943 atm= 0.137 atm + 0.566 atm + PN₂

Solving:

1.943 atm= 0.703 atm + PN₂

1.943 atm - 0.703 atm= PN₂

1.24 atm= PN₂

The parcial pressure of N₂ in the mixture is 1.24 atm.

During which phase change does the entropy of a sample of H2O increase?

1. H2O(g) -> H2O(l)
2. H2O(g) -> H2O(s)
3. H2O(l) -> H2O(g)
4. H2O(l) ->H2O(s)

Answers

Answer: 3. H2O(l) -> H2O(g)

Explanation: Entropy is a measure of the randomness or disorder a substance. Gasses have the greatest amount of entropy and solids have the least amount of entropy. The entropy of a sample of H2O increases as liquid water evaporates and changes to a gas.

The entropy of a sample of H2O increases when the phase of change that is  H2O(l) -> H2O(g) occurs. This is because entropy increases when a substance undergoes sublimation (solid to gas) or evaporation (liquid to gas).

What is meant by entropy?The entropy of an object is a measure of the amount of energy that is unavailable to do work.Entropy depends upon the randomness of molecules, number of molecules, and heat content. During which phase does entropy increase?A substance in the solid phase has low entropy.A substance in the liquid phase has medium entropy.A substance in the gas phase has high entropy.When a substance goes from a solid to a gas (sublimation) or from a liquid to a gas (evaporation), entropy increases.

When the given sample of H2O changes its phase from liquid to gas, the entropy increases. It also happens when it changes from solid to gas.

Thus, option 3: H2O(l) -> H2O(g), the entropy increases.
