Answer:
5 g
Explanation:
Step 1: Write the balanced equation
3 AgNO₃(aq) + Na₃AsO₄(aq) ⇒ Ag₃AsO₄(s) + 3 NaNO₃(aq)
Step 2: Calculate the reacting moles of Na₃AsO₄
100.0 mL of 0.1 M Na₃AsO₄ react.
0.1000 L × 0.1 mol/L = 0.01 mol
Step 3: Calculate the moles of Ag₃AsO₄ formed from 0.01 moles of Na₃AsO₄
The molar ratio of Na₃AsO₄ to Ag₃AsO₄ is 1:1. The moles of Ag₃AsO₄ formed are 1/1 × 0.01 mol = 0.01 mol.
Step 4: Calculate the mass corresponding to 0.01 moles of Ag₃AsO₄
The molar mass of Ag₃AsO₄ is 461.61 g/mol.
0.01 mol × 461.61 g/mol = 5 g
grams can be converted to moles and vice versa which conversion factors is/are used for this
Answer:
Converting Grams to Moles of an Element and Vice Versa.
We can convert back and forth between grams of an element and moles.
The conversion factor for this is the molar mass of the substance. The molar mass is the ratio giving the number of grams for each one mole of the substance
molar mass is the factor
Grams can be converted to moles and vice versa so the conversion factor which is used for this is molar mass.
How do we convert mass into moles?Mass of any substance will be converted into moles by using the below equation:
n = W/M, where
n = moles
W = given mass
M = molar mass
By using the above formula we can convert the mass of any object to moles and moles to mass.
Hence conversion factor which is used for this is molar mass(M).

How does knowing the reactants and products
help you classify a chemical reaction? Write a
short paragraph explaining.
Answer:
Here's the Sample Response: The reactants and products determine the type of chemical reaction. If there are more products than reactants, then it is a decomposition reaction. If there are more reactants than products, it is a synthesis reaction. If oxygen is a part of the reactant, it is a combustion reaction. If one ion replaces another, it is a single replacement reaction. If there are two compounds in a reactant where cations switch, it is a double replacement reaction.

Why can gases and liquids be paired but not solids?
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

A sample of water has a volume of two liters and is shaped like a cylinder in one container. In a much larger container, the water
still has a volume of two liters, but it is shaped like a rectangle
What state of matter is the water in?
OA. Solid
OB. magnetic
OC. plasma
OD. liquid
Reset
Submit
Answer:
D. liquid
Explanation:
Matter, which is any substance that has weight and occupies space, can exists in three states namely: solid, liquid and gaseous. In this question, water is being described as matter.
According to this question, a sample of water of volume 2litres is shaped like a cylinder in one container and shaped like a rectangle in another larger container. Based on this observation, the water sample is in a LIQUID STATE because a liquid has no indefinite shape but takes the shape of its container.
Hence, this water sample, takes the shape of its cylindrical container in the first scenario and shape of its rectangular container in the second scenario.

How much

when 1.5 current is passed through water for 1.5 hours?
0.042 moles of Hydrogen evolved
Further explanationGiven
I = 1.5 A
t = 1.5 hr = 5400 s
Required
Number of Hydrogen evolved
Solution
Electrolysis of water ⇒ decomposition reaction of water into Oxygen and Hydrogen gas.
Cathode(reduction-negative pole) : 2H₂O(l)+2e⁻ ⇒ H₂(g)+2OH⁻(aq)
Anode(oxidation-positive pole) : 2H₂O(l)⇒O₂(g)+4H⁻(aq)+4e⁻
Total reaction : 2H₂O(l)⇒2H₂(g)+O₂(g)
So at the cathode H₂ gas is produced
Faraday : 1 mole of electrons (e⁻) contains a charge of 96,500 C
[tex]\tt mol~e^-=\dfrac{Q}{96500}[/tex]
Q = i.t
Q = 1.5 x 5400
Q = 8100 C
mol e⁻ = 8100 : 96500 = 0.084
From equation at cathode , mol ratio e⁻ : H₂ = 2 : 1, so mol H₂ = 0.042

Mention any two factors that determines Cis/Trans Isomerization
Answer:
1. There most not be rotation within the molecule.
2. Two non identical group must be present in the double bonded carbon atom.
Explanation:
This is because cis/ trans isomerism are that exhibit different structural configurations where the atoms are spartially arranged. They are also refered to as geometric isomers. They cannot be interconverted at room temperature because it requires the bonds to be broken and restructured.
Cis shows that the functional groups on present in the same side which trans isomerism show that the functional groups are on opposite sides.

A 600. mL beaker has an inner diameter of 77.0 mm. What is the vertical distance between the 100. mL marks on the side of the beaker
Answer:
[tex]h=12.9cm[/tex]
Explanation:
Hello!
In this case, since we can consider the beaker until the 100-mL mark as a cylinder, we can use the following equation to relate its diameter, vertical distance or height and volume:
[tex]V=\pi h\frac{d^2}{4}[/tex]
Thus, since we know the diameter, volume (which is equivalent to 600 cm³) and π, we can plug in to obtain:
[tex]600cm^3=\pi *h*\frac{(77.0mm)^2}{4}[/tex]
It means it is necessary to take the mm to cm and solve for h:
[tex]h=\frac{600cm^3}{\pi*\frac{(7.70cm)^2}{4}} \\\\h=12.9cm[/tex]
Best regards!
The distance between each 100 mL mark is 2.15 cm.
The volume of a cylinder is obtained using the formula;
V = πr^2h
Now, we have the following information;
Volume of the cylinder = 600. mL or 600 cm^3
Diameter of the cylinder = 77 mm or 7.7 cm
Radius of the cylinder = 7.7/2 = 3.85 cm
Height of the cylinder = h
Hence;
600 = 3.142 × ( 3.85 )^2 × h
h = 600/3.142 × ( 3.85 )^2
h = 12.88 cm
There are six 100 mL marks on the beaker, the distance between each 100 mL mark = 12.88 cm/6 = 2.15 cm

How would kinetic energy of the dominoes be affected if the first domino did not hit the second one?(((20 points)))
Answer:
Not affected.
Explanation:
Kinetic energy of the dominoes not affected if the first domino did not hit the second one because no kinetic energy is lost due to no collision. If the first domino hit the second one, its kinetic energy decreases and changes in other form of energy such as heat and sound energy etc. But when there is no collision occur, then there is no change in the kinetic energy of dominoes.
Why must the red blood cells and the solution in the beaker be isotonic?
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

What would you use to determine whether an acid or alkali has been added to a solution?
A. Reactant
B. Indicator
C. Adjustor
D. Identifier
Answer:
B. Indicator
Explanation:
An indicator is used to determine whether an acid or alkali has been added to a solution.
An acid or alkali changes the hydrogen ion concentration in solution. This is indicated by the pH of the solution after which the acid or alkali has been added.
To see this change, indicators are used. An indicator employs color changes to show a change in chemical properties which pertains to the pH. There are several indicators used which are litmus paper, phenolphthalein, methyl orange
