How do we use positive and negative signs to communicate the direction of a vector
Answer:
Two vectors are equal if they have the same magnitude and the same direction. Just like scalars which can have positive or negative values, vectors can also be positive or negative. A negative vector is a vector which points in the direction opposite to the reference positive direction.
g Suppose a 49. L reaction vessel is filled with 1.5 mol of NO. What can you say about the composition of the mixture in the vessel at equilibrium
The question is incomplete, the complete question is:
At a certain temperature, the equilibrium constant [tex]K_{eq}[/tex] for the following reaction is 0.74:
[tex]NO_3(g)+NO(g)\rightleftharpoons 2NO_2(g)[/tex]
Suppose a 49.0 L reaction vessel is filled with 1.5 mol of [tex]NO_3[/tex] and 1.5 mol of NO. What can you say about the composition of the mixture in the vessel at equilibrium?
A. There will be very little [tex]NO_3[/tex] and NO.
B. There will be very little [tex]NO_2[/tex]
C. Neither of the above is true.
Answer: The correct option is B. there will be very little [tex]NO_2[/tex]
Explanation:
We are given:
Initial moles of [tex]NO_3[/tex] = 1.5 moles
Initial moles of NO = 1.5 moles
Volume of vessel = 49 L
As, moles of reactants and moles of products are equal, the volume term will not appear in the equilibrium constant expression.
Equilibrium constant for the reaction = 0.74
For the given chemical equation:
[tex]NO_3(g)+NO(g)\rightleftharpoons 2NO_2(g)[/tex]
Initial: 1.5 1.5 -
At eqllm: 1.5-x 1.5-x 2x
The expression of equilibrium constant for the above reaction:
[tex]K_{eq}=\frac{[NO_2]^2}{[NO_3]\times [NO]}[/tex]
Putting values in above equation, we get:
[tex]0.74=\frac{(2x)^2}{(1.5-x)(1.5-x)}\\\\x=-1.13, 0.451[/tex]
Neglecting the negative value of equilibrium constant because concentration cannot be negative
Equilibrium concentration of [tex]NO_3[/tex] = (1.5 - x) = (1.5 - 0.451) = 1.049 moles
Equilibrium concentration of NO = (1.5 - x) = (1.5 - 0.451) = 1.049 moles
Equilibrium concentration of [tex]NO_2[/tex] = 2x = [tex](2\times 0.451)=0.902mol[/tex]
There are 3 possibilities:
If [tex]K_{eq}<1[/tex], the reaction is reactant favoredIf [tex]K_{eq}>1[/tex], the reaction is product favored.If [tex]K_{eq}=1[/tex], the reaction is in equilibrium.Here, the value of [tex]K_{eq}=0.74[/tex], which is less than 1, therefore the reaction is reactant favored and we can say that there will be very little [tex]NO_2[/tex].
Hence, the correct option is B. there will be very little [tex]NO_2[/tex]

How do you know whether or not a chemical
reaction equation follows the law of
conservation of mass?
Answer:
- Because it has or not the same number of atoms at each side.
- Because the mass of reactants and product is or not the same after the reaction.
Explanation:
Hello!
In this case, since the law of conservation of mass states that matter cannot be created nor destroyed; when we see a chemical reaction, we need to make sure that the amount of atoms is the same at both reactants and products; for instance the formation of water requires four hydrogen atoms and two oxygen atoms at both reactants and products sides as shown below:
[tex]2H_2+O_2\rightarrow 2H_2O[/tex]
Another way is by proving that the total mass of products equals the total mass of reactants once the reaction has gone to completion.

Explanation:
Hello!
In this case, since the determination of the oxidation states is performed by using the well-known charge balances, we can proceed as shown below:
- P in PBr3: Here, bromide ions have an oxidation state of -1, so we follow:
[tex]P^xBr_3^-\\\\x-3=0\\\\x=+3[/tex]
Thus, the oxidation state is +3.
- N in N2: Here, since nitrogen is bonding with nitrogen and it is neutral, we infer its oxidation state is 0.
- As in H3AsO4: Here, oxygen is -2 and hydrogen +1, so we follow:
[tex]H_3^+As^xO_4^{-2}\\\\3+x-8=0\\\\x=8-3\\\\x=5[/tex]
Thus, the oxidation state is +5.

Step 2: Identify Conversions
Molar Mass of C - 12.01 g/mol
Molar Mass of Br - 79.90 g/mol
Molar Mass of CBr₄ - 12.01 + 4(79.90) = 331.61 g/mol
Step 3: Convert
[tex]\displaystyle 675 \ g \ CBr_4(\frac{1 \ mol \ CBr_4}{331.61 \ g \ CBr_4}) = 2.03552 \ mol \ CBr_4[/tex]
Step 4: Check
Follow sig fig rules and round. We are given 3 sig figs.
2.03552 mol CBr₄ ≈ 2.04 mol CBr₄
Answer:
[tex]\boxed {\boxed {\sf About \ 2.04 \ moles \ of \ CBr_4}}[/tex]
Explanation:
1. Define Formula
The compound is carbon tetrabromide. The tetra indicates 4 atoms of bromine.
Carbon (C)+ 4 Bromine (Br) = CBr₄2. Find Molar Mass
There are 2 elements in this compound: carbon and bromine. Use the Periodic Table to find the molar masses of these elements.
Carbon (C): 12.011 g/mol Bromine (Br): 79.90 g/molThe molar mass is based on the number of atoms in the compound. The compound has 1 atom of carbon and 4 atoms of bromine.
CBr₄= 1(12.011 g/mol) + 4(79.90 g/mol)
= 12.011 g/mol+319.60 g/mol = 331.611 g/mol
3. Convert Grams to Moles
We want to convert 675 grams to moles. We should use the molar mass as a fraction.
[tex]\frac{331.611 \ g \ CBr_4}{1 \ mol \ CBr_4 }[/tex]
Multiply by the given number of grams.
[tex]675 \ g \ CBr_4 *\frac{331.611 \ g \ CBr_4}{1 \ mol \ CBr_4 }[/tex]
Flip the fraction so the grams of CBr₄ will cancel.
[tex]675 \ g \ CBr_4 *\frac{1 \ mol \ CBr_4 }{331.611 \ g \ CBr_4}[/tex]= [tex]675 \ *\frac{1 \ mol \ CBr_4 }{331.611 \ }[/tex]
[tex]\frac{675 \ mol \ CBr_4 }{331.611 \ }[/tex] = [tex]2.03551752 \ mol \ CBr_4[/tex]
4.Round
The original measurement, 675 grams has 3 significant figures (6,7 and 5), so our answer must have the same.
For the answer we found, 3 sig figs is the hundredth place.
[tex]2.03551752 \ mol \ CBr_4[/tex]
The 5 in the thousandth place tells us to round the 3 to a 4.
[tex]\approx 2.04 \ mol \ CBr_4[/tex]
There are about 2.04 moles of carbon tetrabromide in 675 grams.

How many molecules of N2O4 are in 76.3g N2O4? The molar mass of N2O4 is 92.02 g/mol.
a. 4.59 × 10^25 N2O4 molecules
b. 5.54 × 10^25 N2O4 molecules
c. 7.26 × 10^23 N2O4 molecules
d. 1.38 × 10^24 N2O4 molecules
e. 4.99 × 10^23 N2O4 molecules
Answer:
4.99*10²³ molecules of N₂O₄ are in 76.3 g of N₂O₄
Explanation:
Avogadro's Number is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.
You know that the molar mass of N₂O₄ is 92.02 g/mol, and you have 76.3 g. Then you can apply the following rule of three: 92.02 grams are present in 1 mole of the compound, 76.3 grams in how many moles are they?
[tex]amount of moles= \frac{76.3 grams*1 mole}{92.02 grams}[/tex]
amount of moles= 0.83 moles
Then, you can apply another rule of three: if by definition of Avogadro's number 1 mole of the compound has 6.023*10²³ molecules, 0.83 moles of the compound, how many molecules will it have?
[tex]amount of molecules= \frac{0.83 moles*6.023*10^{23}molecules }{1 mole}[/tex]
amount of molecules= 4.99*10²³
4.99*10²³ molecules of N₂O₄ are in 76.3 g of N₂O₄
