Answer:
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.

Detective Gundy found several areas in a warehouse where fires appeared to have started. What can he MOST likely conclude from this
evidence?
A Someone deliberately set fires at different points around the warehouse
B. Several people accidentally dropped lit cigarettes around the warehouse
OC Strong winds spread the fire throughout multiple areas in the warehouse,
D. There was no accelerant used to start any of these fires
Given what we know, we can confirm that based on the evidence found, someone deliberately set fires at different points around the warehouse.
Why do we think the fires were deliberate?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.

An electric motor in a bike has a voltage of 24 V and produces 240 W of power. How much current does it draw?]
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
What is power?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
How to determine the currentFrom 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

3 grams of Aluminum was heated from 20 °C to 662 °C while absorbing
1728 I of heat. What is the specific heat of Aluminum?
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.
What is specific heat capacity?The specific heat capacity of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
Q = quantity of heat absorbed or releasedm = mass of substancec = specific heat capacity∆T = change in temperatureAccording 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.

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.
Characteristics of a galvanic cellIn 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.

Which best explains the relationship between evaporation and temperature?
A liquid evaporates slower at lower temperatures because the molecules are more spread apart and are not pushed as easily from the liquid’s surface.
A liquid evaporates faster at lower temperatures because the attractions are decreased and more particles can escape the surface of the liquid.
A liquid evaporates slower at higher temperatures because the vapor pressure of the liquid is higher, so fewer molecules can escape the surface.
A liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid.
Answer:
A liquid evaporated slow at higher temperature bz the vapour pressure of the is higher so few molecule can escape the surface

If 10.0L of hydrogen gas, and 6.0L of oxygen gas were used in
problem 1, how many liters of water vapor would be produced?
PLEASE HELP <3
From the mole ratio of the gases, 10 moles of hydrogen will produce 10 moles of water, and if 10.0 L of hydrogen and 6.0 L of oxygen were used, 10.0 L of water will be produced.
What is the mole ratio of reactants in the formation of water?The mole ratio of the reactants in the formation of water can be shown from the equation below:
[tex]2H_2 + O_2 \rightarrow 2H_2O[/tex]
Mole ratio of hydrogen to oxygen is 2:1
10 moles of hydrogen will require 5 moles of oxygen, therefore hydrogen is the limiting reactant.
10 moles of hydrogen will produce 10 moles of water.
1 mole of a gas has a volume of 22.4 L.
If 10.0 L of hydrogen and 6.0 L of oxygen were used, 10.0 L of water will be produced.
Therefore, the volume ratio of gas equals mole ratio of gas.
