Answer:

Mountain ranges and prevailing winds.

Explanation:

Mountain ranges and prevailing winds are the factors that is responsible for the difference in the precipitation between Nevada and Washington states. The Washington state is located along the coastal region of pacific ocean and having more mountain ranges which causes more rainfall in that region while on the other hand, Nevada state comprise of plateau, basins and far away from the ocean which is the main cause of lower rainfall as compared to Washington state.

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

[tex]n = \frac{1.00 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{1}{6.02} \\ = 0.166112[/tex]

Answer:

d. 200.

Explanation:

The reaction is:

2KMnO4 + 16HCl ----> 2KCl + 2MnCl2 + 8H2O + 5Cl2

So 2 moles of KCL are produced form  16 moles of HCL

So 25 moles KCL are made from   25 * (16/2) HCl.

= 25 * 8

= 200 moles. HCl.

Answer:

pressure of gas are constant describe the relationship between moles and temprature

The statements correctly describes the relationship between volume and temperature is pressure of gas are constant.

The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure. In comparison to the surrounding pressure, gauge pressure is the pressure. Pressure is expressed using a variety of units.

The volume of a gas is directly proportional to the number of moles of gas when both temperature and pressure are constant. The pressure of a gas is directly proportional to the number of moles of gas when both temperature and volume are constant.

In layman's words, the volume of a fixed mass of gas is exactly proportional to temperature at constant pressure.

Thus, If the pressure and temperature remain constant, the volume of a gas is directly proportional to the number of moles in the gas.

Explanation:

Answer:

0.78 atm

Explanation:

Applying general gas equation

PV/T= P'V'/T'................ Equation 1

Where P = initial pressure, T = Initial temperature, V = Initial Volume, P' = Final pressure, V' = Final Volume, T' = Final Temperature.

make P' the subject of the equation

P' = PVT'/TV'.............. Equation 2

From the question,

Given: P = 1.00 atm, V = 5.20 L, T = 60°C = (273+60) = 333K, V' = 6.00 L, T' = 27°C = (27+273)K = 300 K

Substitute these values into equation 2

P' = (1×5.2×300)/(333×6)

P' = 1560/1998

P' = 0.78 atm.

Answer:

218.98 grams

Explanation:

Given that,

No. of moles, n = 2.3

The molar mass of magnesium chloride is 95.211 g/mol.

We need to find the mass of 2.3 moles of magnesium chloride.

We know that,

No. of moles = given mass/molar mass

Let m be the given mass. So,

[tex]m=n\times M\\\\=2.3\times 95.211 \\\\=218.98\ g[/tex]

So, the required mass is equal to 218.98 grams.

Answer:

V₂ = 13.44 L

Explanation:

Given that,

Initial volume, V₁ = 5 L

Initial pressure, P₁ = 0.863 atm

Final pressure, P₂ = 0.321 atm

We need to find the final volume of the balloon. The relation between the volume and pressure is given by :

[tex]P_1V_1=P_2V_2[/tex]

Where

V₂ is the volume of the balloon

So,

[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{0.863 \times 5}{0.321 }\\\\V_2=13.44\ L[/tex]

So, the final volume of the balloon is equal to 13.44 L.

Answer:

110.25grams

Explanation:

The balanced chemical equation is as follows:

H2SO4 + 2NaOH → Na2SO4 + 2H20

Based on the balanced chemical equation of the reaction given above, 1 mole of sulphuric acid (H2SO4) is required to react with 2 moles of sodium hydroxide (NaOH).

Hence, if 1 mol of H2SO4 is needed to react with 2 moles of NaOH

Then, 2.25mol of NaOH will be required to react with;

= 2.25/2

= 1.125mol of H2SO4

Using the formula, mole = mass/molar mass, we can convert the molar value of H2SO4 to its mass value.

Molar mass of H2SO4 = 1(2) + 32 + 16(4)

= 2 + 32 + 64

= 34 + 64

= 98g/mol

Therefore, mole = mass/molar mass

1.125 = mass/98

mass = 98 × 1.125

mass = 110.25grams of H2SO4

Answer:

2(C4H10)+13(O2)->8(CO2)+[](H20)

Explanation:

sorry i couldn’t get the last one

The chemical reaction by providing the correct whole number coefficients: number coefficients will be 2C4H10 + 13O2 WILL GIVE 8CO2 + 10H2O .this will be the balanced reaction.

Balance elements in the equation other than O and H. Balance the oxygen atoms by adding the appropriate number of water ( H 2O) molecules to the opposite side of the equation.

Balance the hydrogen atoms (including those added in step 2 to balance the oxygen atom) by adding H + ions to the opposite side of the equation.

When writing an equation for a chemical reaction, the two sides of the equation should balance and need the same number of each kind of element on both sides.

Therefore the given chemical equation is balanced in the following form, 2C4H10 + 13O2 WILL GIVE 8CO2 + 10H2O

Answer:

nacl cacl kcl mgcl k2so4 na2co3 na2so4 kno3 nahco3 naco3

Explanation:

Explanation:

a. pressure always favors the side with fewer molecules. in this reaction as both the sides have equal number of molecules, there won't be any change in the position of the equilibrium.

b. when the concentration of the hydrogen gas is increased. more particles would take place in the reaction and so, the rate of reaction would increase favoring the reaction concerning hydrogen gas molecules (backward reaction in this case) therefore, equilibrium would shift to the backward reaction (left).

c. as forward reaction is endothermic, when temperature is increased the equilibrium will shift to the forward reaction (right).

d. catalyst would not have any effect on the position of the equilibrium. it will only increase the rate of reaction.
