Explanation:

The force acting downwards or opposite to normal force which reduces the movement is indicated with a negative sign. Hence, the force of -7N is frictional force.

Force is an external agent acts on a body to change it from the state of rest or motion. There are various forces such as frictional force, magnetic force, gravitational force etc.

Frictional force is the resistive force which make the object resistive in motion. Thus it is indicated with a negative sign. Gravitational force is the force by which an object attracts other objects into its centre of mass.

Hence, gravitational force also making the body resistive to motion. Here, -10 N is the gravitational force acting on the box and it experience a force of -7N which also resists its force in the opposite direction of the normal force.

Hence, -7N is the force of  friction acting on the body.

The refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

To calculate the kilowatt-hours (kWh) of electric energy used by the refrigerator in 30 days, we need to multiply the power rating by the total running time.

Given:

Power rating of the refrigerator = 500 W

Running time per day = 12 hours

Number of days = 30

First, we need to convert the power rating from watts to kilowatts:

Power rating = 500 W / 1000 = 0.5 kW

Next, we calculate the total energy used in kilowatt-hours (kWh) over the 30-day period:

Energy used = Power rating × Running time × Number of days

Energy used = 0.5 kW × 12 hours/day × 30 days

Energy used = 180 kWh

Therefore, the refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

B. Charges ( a slight positive charge on one end, and a slight negative charge on the other).

The molar mass of the osmotic pressure of a 2.10 mL solution containing 0.181 g of protein dissolved in water is determined to be 18.30 torr at 22° C is 234.89 g/mol.

To solve for the molar mass of the protein, we need to use the formula:

π = MRTi

Where:

First, we need to calculate the molarity of the solution. We can use the formula:

M = n/V

Where:

We can calculate the number of moles of the protein by dividing its mass by its molecular weight:

n = m/MW

Where:

Plugging in the given values:

We can solve for M by rearranging the formula for π:

M = π / (RT)

Plugging in the values:

M = (18.30 torr) / (0.08206 L·atm/mol·K × 295.15 K)

M = 0.771 mol/L

Now, we can solve for the molecular weight (MW) by rearranging the formula for M:

MW = m / n

Plugging in the values:

MW = (0.181 g) / (0.771 mol/L)

MW = 234.89 g/mol

Therefore, the molar mass of the protein is 234.89 g/mol.

Answer:Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)

O2Zn(s) + H2SO4(aq) → 22nH(aq) + SO4(s)

Explanation:

A reaction where one element gets substituted by another is called a single replacement reaction. The balanced equation reaction is Zn(s) + H₂SO₄(aq) → ZnSO₄(aq) + H₂(g). Thus, option B is correct.

A single-displacement reaction is a replacement reaction where the element from a compound gets substituted or replaced by another element from the reactant to produce a product.

The replacement or the substitution is based on the reactivity or the activity series. The element with more strength will replace the element that is weak and has lower strength.

The balanced single-displacement reaction is given as,

Zn(s) + H₂SO₄(aq) → ZnSO₄(aq) + H₂(g)

Here, zinc has more reactivity capability than hydrogen and hence replaces to produce zinc sulfate.

Therefore, option B. Zn(s) + H₂SO₄(aq) → ZnSO₄(aq) + H₂(g) is the balanced equation.

The solution to the equation and value of variable 21(3d - 4) + 100 = 58 is d = 2/3.

Solve the equation 21(3d - 4) + 100 = 58, we can begin by simplifying and isolating the variable:

21(3d - 4) + 100 = 58

Distribute 21 to the terms inside the parentheses:

63d - 84 + 100 = 58

Combine like terms:

63d + 16 = 58

Subtract 16 from both sides:

63d = 42

Divide both sides by 63:

d = 42/63

Simplifying the fraction gives:

d = 2/3

The solution to the equation is d = 2/3.

The solution to the equation 21(3d - 4) + 100 = 58 is d = 2/3. By simplifying the equation, we find that dividing both sides by 63 results in the solution of d = 2/3, which satisfies the original equation.

The time taken is  15.813 years

Half-life is the time it takes for half of the initial amount of a radioactive substance to decay or transform. The concept of half-life applies to any process that follows exponential decay, such as the decay of radioactive isotopes or the breakdown of certain chemical compounds.

Given that;

N/No = (1/2)^t/t1/2

N = Number at time t

No = number initially present

t = Time taken

t1/2 = Half life

Thus;

12.5/100 = (1/2)^t/5.271

0.125 =  (1/2)^t/5.271

(1/2)^3 =  (1/2)^t/5.271

Complete this sentence. The electrical conductivity of a sample will stay the same when the size of the sample increases.

Explanation:

Size does not effect electrical conductivity.

Electrical conductivity is the flow of the electrical charge in the material. The electrical conductivity of a sample will stay the same when the size of the sample increases. Thus, option 2 is correct.

Electrical conductivity is the fundamental property that measures the ability of the substance or material to allow the flow of the charges and current through the substance.

It is the opposite of electrical resistivity which resists the flow of the electrons and charges to produce an electric current. The electrical conductivity is independent of the size of the substance.

Electrical conductivity rather depends on temperature, the concentration of ions, and the type of the ions. The increase or decrease in the size does not affect the electrical conductivity.

Therefore, in option 2. the electrical conductivity is not affected by the size of the sample.

ph of solution at equivalence point is 7.

Strong Acid and Strong Base Titration:

A neutral salt and water are created when a strong acid and strong base react with one another. The titration of a strong acid with a strong base takes place in several places. The pH is determined by the strong acid solution before any titrant is introduced. The extra acid controls the solution's pH before the equivalence point. The pH is equivalent to 7 at the equivalency point. The excess strong base determines the pH of the solution past the equivalence point.

At equivalence point the solution becomes neutral and the pH becomes 7.

Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution. At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.
