Plates on Earth are moving quickly. Yet, friction causes them to travel more slowly. So, the correct options are B and C.

Tectonic plates are enormous fragments of the upper mantle and crust of the Earth. They are composed of both continental and oceanic crust. Earthquakes occur around mid-ocean ridges and the large faults which mark the edges of the plates.

The Earth's plates are shifting swiftly. Nevertheless, friction slows their movement. Gravity causes the floating plates to rise and fall. On occasion, the movement of tectonic plates results in earthquakes.

When compared to the Earth's mantle, the plates behave like solid, unyielding shells. The lithosphere is the name given to this thick outer layer.

Thus, the correct options are B and C.

Answer: It is a basic solution with pH =8.51

Explanation:

We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M

But We know thar

[OH-] [H+] = 1 × 10^-14

To get the Hydrogen ion [H+] concentration, we have that

[H+] = 1 × 10^-14 M/[OH-]

= 1 × 10^-14 M/3.26 x 10-6 M

    =  3.067 x 10^-9 M

But, pH = - log [H+]

Therefore,

pH = - log (3.067 x 10^-9)

pH=8.51

when  pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.

Answer:

the answer is b

Explanation:

Answer:

Option B. It is a basic solution.

Explanation:

To know which option is correct, let us calculate the pH of the solution.

First, we shall determine the pOH of the solution. This is illustrated below:

Concentration of Hydroxide ion, [OH¯] = 3.5×10¯⁶

pOH =.?

pOH = –Log [OH¯]

pOH = –Log 3.5×10¯⁶

pOH = 5.5

Finally, we shall determine the pH. This can be obtained as follow:

pOH = 5.5

pH =?

pH + pOH = 14

pH + 5.5 = 14

Collect like terms

pH = 14 – 5.5

pH = 8.5

The pH scale reads as follow:

0 to 6 => Acidic

7 => Neutral

8 to 14 => Basic

Comparing the pH of the solution (i.e 8.5) with the pH scale, we can conclude that the solution is basic because the pH of solution lies between 8 and 14.

Answer:

Explanation:

When you use electricity to charge your car, you can integrate renewable resources like solar into the fueling process. Without solar, your electric vehicle is still effectively running off of fossil fuels – it's just the fossil fuels utilized at the power plant and not within your engine.

Fossil fuels include substances like natural gas, coal, and oil. It is possible for electric cars to run on these fossil fuels. Fossil fuels like coal are burnt up to generate electricity. So when cars run on electricity, they are indirectly tapping into fossil fuels.

Answer:

1.0 L

Explanation:

Use the ideal gas law PV=nRT where P is pressure = 1100 kPa, V is the volume you are calculating, n is the number of moles which can be calculated by dimensional analysis and the periodic table, R is the ideal gas constant in this case R=8.314 kPa L/K mol, and T is the temperature in kelvins. See attached image for work through. 1.0 L is the answer with two sig figs.

Answer:

Reduced air pressure also has a serious effect on the human body. Reduced air pressure means that there is less oxygen available to the body. For lungs to inflate, the air pressure in your lungs has to be less than the air outside the lungs. This is because air moves from high-pressure areas to low-pressure areas.

Answer:

3.75 moles

Explanation:

The chemical equation is 2CH₃OH + 3O₂ -> 2CO₂ + 4H₂O

2 moles of CH₃OH are burned by 3 moles of O₂

For 2.5 moles of CH₃OH are burned by x moles of O₂

Let's solve for x :

2*x=2.5*3 => 2*x=7.5 => x=3.75 moles of O₂ are needed to burn 2.5 moles of CH₃OH

Answer:

T₂ = 478.93 K

Explanation:

Given that,

Initial pressure, P₁ = 178 kPa

Initial temperature, T₁ = 37°C = 310 K

Final pressure, P₂ = 275 kPa

We need to find the new temp of the air in the tire, assuming the volume is constant. We know that,

[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{275\times 310}{178}\\\\T_2=478.93 K[/tex]

So, the new temperature is equal to 478.93 K.

Answer:

38.75 L

Explanation:

From the question,

Applying Boyles Law,

PV = P'V'....................... Equation 1

Where P = Original pressure of the Argon gas, V = Original Volume of Argon gas, P' = Final pressure of Argon gas, V' =  Final Volume of Argon gas.

make V the subject of the equation

V = P'V'/P.................... Equation 2

Given: P = 34.6 atm, V' = 456 L, P' = 2.94 atm.

Substitute these values into equation 2

V = (456×2.94)/34.6

V = 38.75 L

Answer: The balanced equation is [tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]

Explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example, [tex]AlCl_{3} + Cs \rightarrow CsCl + Al[/tex]

Here, number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

To balance this equation, multiply Cs by 3 on reactant side and multiply CsCl by 3 on product side.

Hence, now the equation will be as follows.

[tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]

Here, number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

Thus, we can conclude that this equation is balanced.

Coniferous forests grow in a wide range of climates, from the coldest polar regions to the warmest tropical regions and everything in between. This statement is true.

Conifers are  a type of gymnosperm plants bearing cone like structures in which the seeds are located. Don't be fooled by the fact that coniferous woods are widespread around the world. Some of the wildest trees in the world can be found there.

Hyperion, a coastal redwood tree, is the tallest tree in the world, reaching a height of 379 feet, equivalent to a 35-story structure. From Siberia to Canada, coniferous rainforest biomes can be found. They have cold winters and warm to hot summers.

Temperatures in coniferous forests are quite low all year long. Summertime temperatures range from -7°C to 21°C, while the average wintertime temperature ranges from -54°C to -1°C. Hence, the statement is true.

Answer:

C4H6O3 + H2O → 2C2H4O2

Explanation:

The four ionic species initially in solution are Na⁺, PO₄³⁻, Cr³⁺, and Cl⁻. Since the precipitate is composed of Cr³⁺ and PO₄³⁻ ions, the spectator ions must be Na⁺ and Cl⁻.

The complete ionic equation is 3Na⁺(aq) + PO₄³⁻(aq) + Cr₃⁺(aq) + 3Cl⁻(aq) → 3Na⁺(aq) + 3Cl⁻(aq) + CrPO₄(s).

So the balanced net ionic equation for this reaction would be Cr³⁺(aq) + PO₄³⁻(aq) → CrPO₄(s).
