what is the dilution factor if you add a 0.1ml aliquot of a specimen to 9.9 dilutent
The dilution factor : 100
Further explanationThe dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution
From equation of dilution :
M₁V₁=M₂V₂
[tex]\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}[/tex]
Volume of aliquot = 0.1 ml
Volume of diluent = 9.9 ml
So final volume :
[tex]\tt V_f(final~volume)=volume~aliquot+volume~diluent\\\\V_f=0.1+9.9=10~ml[/tex]
The dilution factor (DF) :
[tex]\tt D_f=\dfrac{V_f}{V_i}\\\\D_f=\dfrac{10}{0.1}=100[/tex]

If 765 mL of a gas at 2.78 atm, has the volume Change to 2.47 L , What is the pressure of the
gas in atm?
Answer:
0.87 atmExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question
2.47 L = 2470 mL
We have
[tex]P_2 = \frac{765 \times 2.78}{2470} = \frac{2142}{2470} \\ = 0.867206...[/tex]
We have the final answer as
0.87 atmHope this helps you

Concept: Chemical Analysis
You need to start by graphing the data and then analyzing it.We can see that the horse has a distance in meters of 980 at the end of the 10 seconds hence it is the fastest.The horse line has a linearly representation, while the alternate line has parabolic tendencies towards the end. The steeper line indicates a faster change in time or velocity which results in a greater distance traveled indicating that the horse is faster.*I have confidence you can graph that*True or False: All metals have high melting points.

How many grams of water will be produced when 1.6 moles of ethanol (CH3CH2OH) are burned completely? Enter a number only (no units) and express your answer using the correct number of significant figures.
Answer:
86
Explanation:
The reaction that takes place is:
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂OFirst we convert moles of ethanol to moles of water:
1.6 mol ethanol * [tex]\frac{3molH_2O}{1molEthanol}[/tex] = 4.8 mol H₂OThen we convert moles of water to grams of water, using its molar mass:
4.8 mol H₂O * 18 g/mol = 86.4 gSo 84.6 grams of water will be produced.
The mass of water, H₂O produced when 1.6 moles of ethanol, C₂H₅OH are completely burned is 86.4 g
We'll begin by writing the balanced equation for the reaction. This is given below
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
From the balanced equation above,
1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.
Next, we shall determine the number of mole of H₂O produced by the reaction of 1.6 moles of C₂H₅OHFrom the balanced equation above,
1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.
Therefore,
1.6 moles of C₂H₅OH will react to produce = 1.6 × 3 = 4.8 moles of H₂O.
Finally, we shall determine the mass of 4.8 moles of H₂O.Mole of H₂O = 4.8 moles
Molar mass of H₂O = (2×1) + 16 = 18 g/mol
Mass of H₂O =?Mass = mole × molar mass
Mass of H₂O = 4.8 × 18
Mass of H₂O = 86.4 gThus, the mass of water obtained from the reaction is 86.4 g

Explanation:
Step 1: (slow)
Step 2: NO3(g) + CO(g) + NO2(g) + CO2(g) (fast)
Overall: NO2(g) + CO(g) + NO(g) + CO2(g)
A two-step reaction mechanism is proposed for a gas-phase reaction, as represented above. Which of the following correctly identifies both the chemical equation for step 1 and the rate law for the overall reaction?
A) The chemical equation for step 1 is 2 NO2(g) → NO(g) + NO3(g), and the rate law is rate = (NO,].
B) The chemical equation for step 1 is NO2(g) + CO(g) + NO(g) + CO2(g), and the rate law is rate = [NO2][CO).
C) The chemical equation for step 1 is NO3(g) + 2 CO(g) + NO(g) + 2 CO2(g), and the rate law is rate = [NO2][CO).
D) The chemical equation for step 1 is NO3(g) + NO2(g) + 2 CO(g) + NO(g) + NO2(g) + 2 CO2(g), and the rate law is rate = [NO3][NO2][CO]".
Answer:
The chemical equation for step 1 is 2 NO2(g) → NO(g) + NO3(g), and the rate law is rate = k[NO2]^2
Explanation:
We know that the rate determining step is the slowest step in a sequence of non elementary reactions.
As we can see, the first reaction is slow so it is the rate determining step. From here we obtain the rate equation.
Also, the specie NO3 is absent in the overall reaction equation indicating that it is merely an intermediate produced in step 1 and used up in step 2.
The chemical equation for step 1 is [tex]2 NO_2(g) \rightarrow NO(g) + NO_3(g)[/tex], and the rate law is [tex]rate = k[NO_2]^{2}[/tex].
The rate -determining step is the slowest step in a sequence of non -elementary reactions. The first reaction is slow so it is the rate determining step. From here we obtain the rate law.
Also, the specie [tex]NO_3[/tex] is absent in the overall reaction equation indicating that it is merely an intermediate produced in step 1 and used up in step 2.
So, the chemical equation for step 1 is [tex]2 NO_2(g) \rightarrow NO(g) + NO_3(g)[/tex], and the rate law is [tex]rate = k[NO_2]^{2}[/tex].

According to the following reaction, if 69 g of KCIO3, decomposes, how many grams of oxygen will form:
2KCIO3 + 2KCl + 302
Answer:
28.8g
Explanation:
I think your chemical equation should be:
2KClO3 → 2KCl +3O2
Number of moles of KClO3
[tex] = \frac{mass}{molar \: mass} [/tex]
[tex] = \frac{69}{39 + 35.5 + 3(16)} [/tex]
[tex] = 0.6mol[/tex]
From the equation,
2 mol of KClO3 : 3 mol of 02
So...
0.6 mol of KClO3 : 0.9 mol of O2
Number of moles of O2= 0.9mol
So the mass of O2 formed = number of moles× molar mass
= 0.9 × 2(16)
= 28.8g
If 69 gram of KClO₃ decomposes then 27.036 grams of oxygen will form.
What is Stoichiometry ?Stoichiometry helps us use the balanced chemical equation to measure the quantitative relationship and it is to calculate the amount of product and reactants that are given in a reaction.
What is Balanced Chemical Equation ?The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
The given balanced equation is
2KClO₃ → 2KCl + 3O₂
According to Stoichiometry, x gram of oxygen will form
= [tex]69\ \text{g of}\ KClO_{3} \times \frac{1\ \text{mol}\ KClO_{3}}{122.55\ g\ KClO_{3}} \times \frac{3\ \text{mol}\ O_2}{2\ \text{mol}\ KClO_{3}} \times \frac{32\ g\ O_2}{1\ \text{mol}\ O_2}[/tex]
= 27.036 grams of Oxygen
Thus from the above conclusion we can say that If 69 gram of KClO₃ decomposes then 27.036 grams of oxygen will form.

Pure sodium metal reacts violently with water according to the equation below
Na + H2O - NaO + H2
17 mol
If 0.75 mol of Na is placed in 500 g of
H,O how many moles of hydrogen
gas will be produced?
0.75 mol
28 mol
1.5 mol
Answer:
0.75 mol
Explanation:
Given data:
Number of moles of Na = 0.75 mol
Mass of water = 500 g
Moles of hydrogen gas produced = ?
Solution:
Chemical equation:
Na + H₂O → NaO + H₂
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 500 g/ 18 g/mol
Number of moles = 27.8 mol
now we will compare the moles of hydrogen gas with both reactant.
Na : H₂
1 : 1
0.75 : 0.75
H₂O : H₂
1 : 1
27.8 : 27.8
sodium will act as limiting reactant it produced small number of moles of hydrogen gas as compared to water.
Thus, number of moles of hydrogen gas are 0.75 mol.
