Which statement correctly compares electric charge with electric current?
A.
They both require a human to make them.
B. Neither require charged particles.
C. They both require a battery and a bulb
D. They both require a movement of charged particles.
Answer:
Your answer would be D) They both require a movement of charged particles
Explanation:
In short terms both the charge and the current are made up of charged particles that are always moving, they constantly move to well... stay charged, if they stopped, then the charge would fade until there is nothing left, and if there is nothing left -it means there would be no electricity to use

You are trying to design a homemade ice pack. As you select the chemicals for this reaction, should you choose an endothermic reaction or an exothermic reaction? Why?
Answer:
Endothermic
Explanation:
Because Endothermic is cold and exothermic is hot and if you are using an ice pack it would be Endothermic and if you were using something that was hot it would be exothermic

What is the volume of a 492.2g sample of Kr gas?
0.007601 L
131.6 L
5.870 L
21.97 L
Answer:
131.6 L
Explanation:
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, the correct option is option B that is 131.5l. There is no force of attraction between the particles.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature. Ideal gas is a hypothetical gas. Vanderwaal behave as ideal gas at high temperature and low pressure.
Mathematically,
PV=nRT
where,
P = pressure=1 atm
V= volume=?
n =number of moles=given mass/ molar mass
= 492.2/ 83.79
= 5.87 moles
T =temperature = 273K
R = Gas constant = 0.0821 L.atm/K.mol
1× V = 5.87 × 0.0821 L.atm/K.mol × 273 K
V =131.5l
131.5l is the volume of a 492.2g sample of Kr gas.
Therefore, the correct option is option B that is 131.5l.

A gas has a volume of 250.0 liters at 17.0 °C and 3.00 atm of pressure. what volume must the gas be increased for the gas to be at STP conditions?
Answer:
0.706 L (Liters)
Explanation:
P1V1 = P2 V2 3 atm 250.0 mL = 1 atm X
T1 T2 290 K 273 K
706 mL = X
According to the question,
Pressure,
Initial, [tex]P_1 = 3 \ atm[/tex]Final, [tex]P_2 = 1 \ atm[/tex]Temperature,
Initial, [tex]T_1 = 17^{\circ} C[/tex] or, [tex]290 \ K[/tex]Final, [tex]T_2 = 273 \ K[/tex]Volume,
Initial, [tex]V_1 = 250 \ L[/tex]Final, [tex]V_2 = \ ?[/tex]By using the Boyl's and Charl's combination law, we get
→ [tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]
or,
→ [tex]V_2 = \frac{P_1 V_1 T_2}{T_1 P_2}[/tex]
By putting the values, we get
→ [tex]= \frac{3\times 250\times 273}{290\times 1}[/tex]
→ [tex]= 706 \ L[/tex]
Thus the aforementioned answer is right.

4. What is the correct surface areas for a 45nm
wide cube?
Answer:
A = 12150 nm²
Explanation:
The side of a cube, a = 45 nm
We need to find the surface area of the cube.
The formula for the surface area of a cube is given by :
A = 6a²
Substituting the value of a in the above formula.
A = 6(45)²
= 12150 nm²
So, the surface area of the cube is 12150 nm²

Calculate the mass of 4.55x1024 molecules of sucrose
Answer:
2584 g
Explanation:
The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.
First we convert molecules into moles by using Avogadro's number:
4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 molNow we convert moles of sucrose into grams, using its molar mass:
7.55 mol * 342.3 g/mol = 2584 gWhich of the following is not a form of precipitation?

An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its
mass
The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.
What is density ?Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.
Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.
Give that, volume of the object = 825 cm³
density = 13.6 g/cm³
Mass = volume × density
m = 825 cm³ × 13.6 g/cm³ = 11220 g
Therefore, the mass of the object is 11220 g.

In the laboratory you dissolve 12.7 g of silver fluoride in a volumetric flask and add water to a total volume of 125. mL. What is the molarity of the solution?
Answer:
Molarity = 2.4 M
Explanation:
Given data:
Mass of silver fluoride = 12.7 g
Volume of water = 125 mL (125 mL× 1 L /1000 mL = 0.125 L)
Molarity of solution = ?
Solution:
Number of moles of silver fluoride:
Number of moles = mass/molar mass
Number of moles = 12.7 g/ 41.98 g/mol
Number of moles = 0.30 mol
Molarity:
Molarity = number of moles of solute / volume in L
Molarity = 0.30 mol / 0.125 L
Molarity = 2.4 M
