The amount of diamine silver chloride = 8.87 g
Further explanationGiven
10 g AgCl
1.00 L of 0.100 M NH3
Required
the amount of diamine silver
Reaction
AgCl + 2 NH₃ → [Ag(NH₃)₂]Cl
mol AgCl :
= mass : MW
= 10 g : 143,32 g/mol
= 0.0698
mol NH₃ :
= M x V
= 0.1 x 1
= 0.1
NH₃ as a limiting reactant
mol [Ag(NH₃)₂]Cl based on NH₃ :
= 1/2 x mol NH₃
= 1/2 x 0.1
= 0.05
Mass diamine silver :
= 0.05 x 177.3822 g/mol
= 8.87 g

What happens to an egg that is not fertilized?
It is reabsorbed by the body.
It travels back up the fallopian tube.
It exits during childbirth.
It is released during menstruation.
Answer:
It's D.
Explanation:
When the egg is not fertilized, the thick uterus lining breaks down and the blood, tissues, and the unfertilized egg come out of the vagina commonly known as menstruation. When the egg is not fertilized the menstrual cycle takes place as the egg is shredded off from the body.
For any chemical process in an isolated system in which all reactants are converted to products, the original mass of reactants must be the final mass of products. is greater than or less than or equal to
Answer:
equal to
Explanation:
This question is depicting the LAW OF CONSERVATION OF MASS/MATTER, which states that matter can neither be created nor destroyed. Hence, in an isolated system, the original mass of the reactants must be EQUAL TO the final mass of the products formed.
In other words, the law states that no matter the change in chemical composition of the reactants in a chemical process, the mass does not change or it remains constant.

MULTIPLE CHOICE QUESTION
Which distance-time graph most
accurately represents the data in the
data table?
Answer:
(a) The slope of distance-time graph gives the speed of the objects.
As the slope of object (B) is the greatest among all, thus B has the largest speed and hence it is the fastest among all the objects.
(b) : As the curve of the objects do not intersect with each other even once, hence they cannot be at the same point on the road at the same time.
(c) : On the y axis (i.e. distance line), 7 small represents 4 km
∴ 1 small line =
7
4
=0.57 km
Position of C at the instant B passes A is 8 km
(d) ; Position of B at the instant it passes C is 2nd small line above 4 km i.e. 4+2×0.57=5.14 km
∴ Distance traveled by B =5.14−0=5.14 kmV

differences between bright half and
Answer:
Explanation:
Bright half starts from a new moon day and ends on a full moon day
dark half starts from a full moon day and ends on a new moon day
Answer and Explanation:
The bright half is the side we see and the dark half is the other side.
If you're referring to the moon, the bright half starts on a new moon day and ends on a full moon, whereas on the other hand dark half starts ona full moon and ends in a new moon, kinda like cycle. There are practically the same and have no big astounding differences between them.
In a submarine beneath the ocean’s surface, a captain peered into a long tube to see possible threats in the sea and air above. This sight tube, called a periscope, was designed by the Frenchman Marie Davey in 1854. Davey’s periscope contained two mirrors, one placed at each end of a vertical tube. The mirrors were set parallel to each other and at 45 degrees to the vertical. The reflective surfaces faced each other. When light from an object on the surface reflected downward, an image appeared to the eye. People in submerged submarines could see what was above them!
Imagine you are in a submerged submarine looking through a periscope. What are some things you might see?

Explanation:
What would be the theoretical yield in grams of carbon dioxide in the reaction shown below if 30 g of C6H12O6 were reacted with an excess of oxygen? C6H12O6 + O2 -> CO2 + H2O
Answer: Thus 44 g of [tex]CO_2[/tex] will be produced if 30 g of [tex]C_6H_{12}O_6[/tex] were reacted with an excess of oxygen
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} C_6H_{12}O_6 =\frac{30g}{180g/mol}=0.17moles[/tex]
The balanced chemical equation is:
[tex]C_6H_{12}O_6 +6O_2(g)\rightarrow 6CO_2+6H_2O(g)[/tex]
As [tex]C_6H_{12}O_6[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.
According to stoichiometry :
1 mole of [tex]C_6H_{12}O_6[/tex] produce = 6 moles of [tex]CO_2[/tex]
Thus 0.17 moles of [tex]C_6H_{12}O_6[/tex] will produce=[tex]\frac{6}{1}\times 0.17=1.0mole[/tex] of [tex]CO_2[/tex]
Mass of [tex]CO_2=moles\times {\text {Molar mass}}=1.0moles\times 44g/mol=44g[/tex]
Thus 44 g of [tex]CO_2[/tex] will be produced if 30 g of [tex]C_6H_{12}O_6[/tex] were reacted with an excess of oxygen.

What do you predict would happen to the cytoplasm of the onion cell as distilled water is added?
Place each noble gas symbol in front of the appropriate partial electron configuration to create an accurate electron configuration.
The noble gas that precedes a given partial electron configuration must itself have an electron configuration that is complete up to the partial electron configuration. The noble gas's electron configuration should, when fully written out right before the partial electron configuration, give us a valid electron configuration for some element.
For the first series, the highest principal energy level has the number 4, so our noble gas should at least be one that is in the third period (numerically, the energy level is the same as the period number). That noble gas would be argon. The partial electron configuration given is not that of a noble gas (note: all noble gases have an electron configuration that contains Np⁶, where N = the highest principal energy level). So, the noble gas that appropriately precedes our first partial electron configuration is [Ar].
Argon's electron configuration is 1s²2s²2p⁶3s²3p⁶. Using the Aufbau Principle, 4s² would correctly follow 3p⁶. [Ar]4s²3d¹⁰4p² is equivalent to writing out 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p²; either way, this would happen to be the electron configuration of germanium.
Now that we hopefully have our fundamentals down, we can apply them to figure out the noble gases that precede the remaining partial electron configurations.
[Kr]5s²4d¹⁰5p⁵: This is the electron configuration of iodine.
[He]2s²2p⁵: This is the electron configuration of fluorine.
[Xe]6s²4f¹⁴5d¹⁰6p²: This is the electron configuration of lead.
[Ne]3s²2: This is the electron configuration of magnesium.

Explanation:
How many grams of NaOH do you need to dissolve to make 1.55 Liters of a 1.55 Molar solution?
Answer:
Mass = 96g
Explanation:
Molarity = number of moles/volume of solvent
According to the provided information, volume = 1.55L, Molarity = 1.55M
number of moles (n) = molarity × volume
n = 1.55 × 1.55
n = 2.4025
n = 2.40mol
For NaOH, molar mass = 23 + 16 + 1 = 40g/mol
mole = mass/molar mass
Mass = molar mass × mole
Mass = 40 × 2.40
Mass = 96g

What is the boiling point of a solution of 1.20g of glycerol, C3H8O3, in 20.0 g of water?
What is the freezing point?
TB solution = 100.3315 °C
T freezing solution = -1.209 °C
Further explanationGiven
1.2 g glycerol
20 g water
Required
the boiling point
the freezing point
Solution
ΔTB = KB . m
ΔTF = KF . m
mass water = 20 g = 0.02 kg
Kb water = 0.51 °C/m
KF water = 1.86 °C/m
mol glycerol :
= 1.2 g : 92,09382 g/mol
= 0.013
molal : the number of moles of solute in 1 kg of solvent
molal of solution :
= 0.013 : 0.02
= 0.65 m
ΔTB = KB . m
ΔTB = TB solution - TB solvent
TB solution - 100 = 0.51 x 0.65
TB solution - 100 = 0.3315
TB solution = 100.3315 °C
ΔTF = KF . m
ΔT = KF . m
ΔTF = 1.86 x 0.65
ΔTF = 1.209
T_f = -1.209 °C

f. What concentration of NaOH would be required to make a solution with
the same pH that was calculated in part d.?
g. Find the percent ionization of NaOH in the above solution.
Answer:
Given
[HONH2] = 0.45M
[OH-] = 5.26 x 10-6 M
HONH2 + H2O -------------> HONH3+ + OH-
Initial 0.45 55 0 0
at equilibrium 0.45-x 55-x x x
Given
[OH-] = x = 5.26 x 10-6 M
Therefore [HONH3+] = x = 5.26 x 10-6 M
pOH = -log[OH-] = -log(5.26 x 10-6) = 5.279
=> pH = 14- pOH = 8.72
From hendersen-hasselbach equaiton
8.72 = pKa + log(0.45/5.26 x 10-6)
=> pKa = 3.788
=> pKb = 14-3.788 = 10.21
percent of ionization = 5.26 x 10-6 * 100/0.45 = 1.17 x 10-3 %
concentration of NaOH required to make the same pH= [OH-] = 5.26 x 10-6 M
Percent of ionization of NaOH = [OH-]*100/NaOH = 5.26 x 10-6 *100/5.26 x 10-6 = 100%
