Warm air rising at the equator and cold air sinking at the poles is an example of…

Answers

Answer:

atmospheric circulation

Explanation:

Atmospheric circulation occurs  because the Sun heats the Earth more at the equator than at the poles.

Warm air is known to rise at the tropics which lies closer to the equator and moves towards the poles. Atmospheric circulation is driven by the rotation of the earth.

The air cools and flows back towards the Equator to be warmed up again. A sort of convection current is thereby set up.

The gases in a hairspray can are at a temperature of 27 C and a pressure of 30 psi. if the gases can reach a pressure of 90 psi, the can will explode.To what Temperature must the gases be raised in order for the can to explode? You can assume volume remains constant..... please help!!!

Answers

The temperature for the can explode : 627 °C

Further explanation

Gay Lussac's Law  

When the volume is not changed, the gas pressure is proportional to its absolute temperature  

[tex]\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

T₁=27 C+273=300 K

P₁=30 psi

Answer:

D Earth's hot interior

Explanation:

The internal heat engine of the earth is the energy source that powers plate movement.

The sun drives the surface process and provides energy for the external heat engine

The earth's interior sources it heat from: decays of radioactive isotopesremnant heat from the formation of the earthfrictional heating from the movement of the earth

Therefore, the heat is used to melt rocks and set up convection currents that drives plate movements.

What is the energy of a photon (J) that has a wavelength of 105 nm?

Answers

Answer:

E = 1.89×10⁻¹⁹ J

Explanation:

Given data:

Wavelength of photon = 105 nm (105 ×10⁻⁹ m)

Energy of photon = ?

Solution:

Formula:

E = hc/λ

h = plancks constant = 6.63×10⁻³⁴ Js

c = speed of wave = 3×10⁸ m/s

by putting values,

E =  6.63×10⁻³⁴ Js ×3×10⁸ m/s / 105 ×10⁻⁹ m

E = 19.89×10⁻²⁶ J.m / 105 ×10⁻⁹ m

E = 0.189×10⁻¹⁷ J

E = 1.89×10⁻¹⁹ J

How many grams are in 2.3 x 10^ -4 moles of calcium phosphate? ​

Answers

Answer:

Mass = 713.4 ×10⁻⁴ g

Explanation:

Given data:

Number of moles of calcium phosphate = 2.3×10⁻⁴ mol

Mass of calcium phosphate = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of calcium phosphate is 310.18 g/mol

by putting values,

2.3×10⁻⁴ mol = mass / 310.18 g/mol

Mass = 2.3×10⁻⁴ mol × 310.18 g/mol

Mass = 713.4 ×10⁻⁴ g

Explanation:

. A certain quantity of electricity is passed through an aqueous

solution of AgNO3 and cupric salt solution connected in series. The

amount of silver deposited is 1.08 g. What is the amount of copper

deposited ? (Atomic wt. of Cu=63.54, Ag=108 g/mole).​

Answers

Answer:

0.32 g

Explanation:

First, we find the number of moles n of silver deposited.

n = m/M where m = mass of silver deposited = 1.08 g and M = Atomic weight of silver = 108 g/mol

n = m/M = 1.08 g/108 g/mol = 0.01 mol

Now, the quantity of electricity Q = nF where n = number of moles of silver = 0.01 mol and F = Faraday's constant = 96500 C/mol

Q= nF = 0.01 mol × 96500 C/mol = 965 C

By the chemical equation for copper,

Cu²⁺ + 2e ⇒ Cu

2 moles of electrons deposits 1 mol of copper, that is

2 × 96500 C deposits 1 mol of copper, then 965 C will deposit x mol

x = 1 mol × 965 C/2 × 96500 C = 1/200 mol = 0.005 mol of copper

So, we find the mass of 0.005 mol of copper using

n = m/M where m = mass of copper deposited = unknown and M = Atomic weight of copper = 63.54 g/mol and n = number of moles of copper = 0.005 mol

m = nM

= 0.005 mol ×  63.54 g/mol

= 0.32 g

The molar solubility of C a ( O H ) 2 C a ( O H ) 2 was experimentally determined to be 0.019 M. Based on this value, what is the K s p K s p of C a ( O H ) 2 C a ( O H ) 2 ?

Answers

Answer:

Ksp = 2.74 x 10⁻⁵

Explanation:

The solubility equilibrium for Ca(OH)₂ is the following:

  Ca(OH)₂(s) ⇄ Ca²⁺(aq) + 2 OH⁻(aq)

I                          0                0

C                       + s               + 2s

E                        s                   2s

According to the ICE table, the expression for the solubility product constant (Kps) is:

Ksp = [Ca²⁺] x ([OH⁻])² = s x (2s)² = 4s³

Then, we calculate Ksp from the solubility value (s):

s = 0.019 M

⇒ Ksp = 4s³ = 4 x (0.019)³ = 2.74 x 10⁻⁵

The Ksp value of Ca(OH)2 is [tex]2.74 \times 10^-^5[/tex].

What is Ksp value?

The Ksp is the solubility product constant.

The solubility equilibrium is

[tex]Ca(OH)_2(s) = Ca^2^+(aq) + 2 OH^-(aq)[/tex]

I                     0                  0

C                     s               +2s

E                     s                 2s

By the ICE table, the expression for Ksp is

[tex]\rm Ksp = [Ca^2^+] \times ([OH^-])^2 = s \times (2s)^2 = 4s^3[/tex]

Now, calculate the Ksp

s, solubility value is 0.019 M

then, [tex]\rm Ksp = 4s^3= 4 \times (0.019)^3 = 2.74 \times 10^-^5[/tex]

Thus, the Ksp value is [tex]2.74 \times 10^-^5[/tex]

Calculate the mass of Aluminum Bromide that can be made with 5.6 moles of Aluminum

Answers

The mass of Aluminum tri bromide that can be made with 5.6 moles of Aluminum is 1,492.90 grams.

What is the relation between mass & moles?

Relation between the mass and moles of any substance will be calculated by using the below equation as:

n = W/M, where

W = given massM = molar mass

Given chemical reaction is:
2Al + 3Br₂ → 2AlBr₃

From the stoichiometry of the reaction, it is clear that:

2 moles of Al = produces 2 moles of AlBr₃5.6 moles of Al = produces 2 moles of AlBr₃

Now mass of AlBr₃ will be calculated by using the above equation as:

W = (5.6mol)(266.59g/mol) = 1,492.90g

Hence required mass of AlBr₃ is 1,492.90g.

If you put a piece of zinc into a solution of copper (I) sulfate and allow the single replacement reaction to go to completion, how will you know which of the reactants is the limiting reactant? Write the balanced equation, including the states of matter of the reactants and products, to help support your answer.

Answers

Explanation:

Reaction of zinc metal in copper sulfate solution.

[tex]\begin{array}{ll}\text { Oxidation : } & \mathrm{Zn}(s) \rightarrow \mathrm{Zn}^{2+}(a q)+2 e^{-}\\\text {Reduction : } & \mathrm{Cu}^{2+}(a q)+2 e^{-} \rightarrow \mathrm{Cu}(s) \\\hline \text { Full Reaction : } & \mathrm{Zn}(s)+\mathrm{Cu}^{2+}(a q) \rightarrow \mathrm{Zn}^{2+}(a q)+\mathrm{Cu}(s)\end{array}[/tex]

Zinc is listed above copper on the activity series, this means that zinc is more easily oxidized than copper. That is why copper(II) ions can act as an oxidizing agent when put into contact with zinc metal. Ions of any metal that is below zinc, such as lead or silver, would oxidize the zinc in a similar reaction.

Why does salt sprinkled on icy roads cause the ice to melt?​

Answers

it lowers the melting point

Answer:

The actual reason that the application of salt causes ice to melt is that a solution of water and dissolved salt has a lower freezing point than pure water. When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on.
