Question 16 of 25
When the maximum amount of solid is dissolved in a solute, what kind of
solution is it?

To determine the substance that comprises the anode and the cathode in a galvanic cell is by determing ;

The material with the larger (more positive) standard reduction potential that will be the cathode.

In a galvanic cell, oxidation which leads to the loss of elctrons occurs at the anode, while reduction ( addition of elctrons ) occurs at the cathode. therefore the materials with a more positive standard reduction potential will be the cathode of the galvanic cell.

Hence we can conclude that The material with the larger (more positive) standard reduction potential will be the cathode.

Explanation:

The mass in grams of He are necessary to fill a balloon having a volume of 4.50×10³ mL to a pressure of 1.14×10³ torr at 25.0ºC is 1.104 grams.

Mass (W) in grams from moles (n) will be calculated by using the below equation:
n = W/M, where

M = molar mass

Moles of helium gas will be calculated by using the ideal gas equation:

PV = nRT, where

R = universal gas constant = 62.363 L.torr / K.mol

P = pressure of gas = 1.14×10³ torr

V = volume of gas = 4.50×10³ mL = 4.50 L

n = moles of gas = ?

T = temperature = 25.0ºC = 298 K

On putting these values on the ideal gas equation, we get

n = (1140)(4.5) / (62.363)(298) = 5130 / 18584

n = 0.276 moles

Now we convert this moles into mass by using the first equation as:

W = (0.276mol)(4g/mol) = 1.104 g

Hence required mass of helium gas is 1.104 grams.

If you know the formula to use you should have no trouble getting the answers.

molality = mols/kg solvent.

mols sucrose = g/molar mass

kg solvent = 0.275 kg.

The specific heat capacity of Aluminum of mass 3 grams that was heated from 20 °C to 662 °C while absorbing 1728 J of heat is 12.5 J/g°C.

The specific heat capacity of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

According to this question, 3 grams of Aluminum was heated from 20 °C to 66.2 °C while absorbing 1728 J of heat.

1728 = 3 × c × (66.2 - 20)

1728 = 138.6c

c = 1728 ÷ 138.6

c = 12.5 J/g°C

Therefore, the specific heat capacity of Aluminum of mass 3 grams that was heated from 20 °C to 662 °C while absorbing 1728 J of heat is 12.5 J/g°C.

but purely citric acid synthetic Acid whose moller mass is equal to 192 g per mole. Okay, so here we have Modernity is even McGarity is equal to 0.5 M and we have volume, so Volume is equal to 200 mililiters  is equal to 0.1 liter  Okay, so they are asking to calculate the mass of what u have  Okay. So first of all, if we want to calculate the mass of then we have to calculate the number of moles. So maturity is equal to the number of moles per volume in liters . So you mean zero point sorry from this one number of moles is equal to So N is equal to m multiplied very weak. So that is equal to 0.1 and 0.5. So that is equal to 0.05 moles. Okay, now the mask is equal to the mass of cool eh is equal to the number of Okay. Number of 0.5 and it is multiplied by 92 g per mole. Then it is equal to 9.6 g. So this is the mass of a present.

Answer:

Electrical energy is the product of power multiplied by the length of time it was consumed. So if we know how much power, in Watts is being consumed and the time, in seconds for which it is used, we can find the total energy used in watt-seconds. In other words, Energy = power x time and Power = voltage x current.

The amount of current the electric motor having a power of 240 W Will draw from the 24 V supply is 10 A

This is defined as the rate in which energy is consumed. Electrical power is expressed mathematically as:

Power (P) = voltage (V) × current (I)

P = IV

From the question given above, the following data were obtained:

Voltage (V) = 24 V

Power (P) = 240 W

Current (I) = ?

P = IV

240 = I × 24

Divide both sides by 24

I = 240 / 24

I = 10 A

Given what we know, we can confirm that based on the evidence found, someone deliberately set fires at different points around the warehouse.

This has to do with the natural way in which fires spread. Fires that occur naturally or accidentally tend to concentrate in one place, then spread throughout the warehouse over time, however, this is not what the detective found. Instead, there are indications that multiple fires started simultaneously.

Therefore, given the very unlikely nature of this occurring naturally, we can confirm that based on the evidence found, someone deliberately set fires at different points around the warehouse.
