Given the following reaction: 2N2O5=2N2O4+O2, if the rate of oxygen production is 0.15M/min, determine:
a. The rate that N2O5 is consumed
b. The rate that N2O4 is produced
Answer:
a. [tex]r_{N_2O_5}=-0.075M/min[/tex]
b. [tex]r_{N_2O_4}=0.075M/min[/tex]
Explanation:
Hello.
In this case, according to the balanced chemical reaction, we can write the law of rate proportions:
[tex]\frac{r_{N_2O_5}}{-2} =\frac{r_{N_2O_4}}{2} =\frac{r_{O_2}}{1}[/tex]
Thus, we proceed as follows:
a. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:
[tex]\frac{r_{N_2O_5}}{-2} =\frac{r_{O_2}}{1}\\\\r_{N_2O_5}=\frac{r_{O_2}}{-2} =\frac{0.15M/min}{-2}\\\\ r_{N_2O_5}=-0.075M/min[/tex]
b. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:
[tex]\frac{r_{N_2O_4}}{2} =\frac{r_{O_2}}{1}\\\\r_{N_2O_4}=\frac{r_{O_2}}{2} =\frac{0.15M/min}{2}\\\\ r_{N_2O_4}=0.075M/min[/tex]

What will a balloon do to a cloth if its negatively charged
Answer:
This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.
Explanation:
Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

Explanation:
Does anyone know how to do this?
Answer
find out the number of moles and use the molar ratio (numbers in front of formulas (in this case they are all 1) to determine how many moles of each product you are going to get theoretically
n=m/M is the equation to use to get moles here
30.8 gm/32.04 g/mol=0.9612 moles of the methanol and also of the formaldehyde so
0.9612 moles of the formaldehyde x molar mass (M) 30.73 g/mol= 29.54 gm which is the theoretical yield you already have the actual yield of 24.7 gm
then divide the actual by the theoretical to get the % yield which is 83.6%

Answer:
shift to restore equilibrium
Explanation:
Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.
Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.
Equilibrium is the state of a reversible reaction when:
• two opposing reactions occur at the same rate;
• the concentrations of reactants and products are constant
How many moles are there 75.56 grams of KHCO3
Explanation:
mole = mass/molar mass
molar mass of KHCO3 = K + H + C + O3
39 + 1 + 12 + 3(16)
= 100g/mol
mass = 75.56
mole = 75.56/100
= 0.7556mol

If 23.2 g of a given gas occupies a volume of 93.2 L at a particular temperature and pressure, what
mass of the gas occupies a volume of 10.4 L under the same conditions?
Answer:
2.59g
Explanation:
Using Avagadro's law equation as follows:
V1/n1 = V2/n2
Where;
V1 = initial volume (litres)
V2 = final volume (litres)
n1 = first amount of gas in grams
n2 = second amount of gas in grams
According to the information provided in this question, v1 = 93.2L, v2 = 10.4L, n1 = 23.2 g, n2 = ?
Using V1/n1 = V2/n2
93.2/23.2 = 10.4/n2
Cross multiply
93.2 × n2 = 23.2 × 10.4
93.2n2 = 241.28
n2 = 241.28/93.2
n2 = 2.588
n2 = 2.59g
The mass of the gas is 2.59g that occupies a volume of 10.4 L under the same conditions.
Avogadro's law equation:V₁/n₁ = V₂/n₂
Where
V₁ = initial volume (litres)
V₂ = final volume (litres)
n₁ = first amount of gas in grams
n₂ = second amount of gas in grams
Given:
V₁ = 93.2L,
V₂ = 10.4L,
n₁ = 23.2 g,
To find:
n₂ = ?
On substituting the values:
93.2/23.2 = 10.4/n₂
93.2 * n₂ = 23.2 * 10.4
93.2* n₂ = 241.28
n₂ = 241.28/93.2
n₂ = 2.588
n₂ = 2.59g
Thus, the mass of the gas is 2.59g.

help !!! pretty please ❤️
Answer:
See below!
Explanation:
To find the symbol of the element, you have to use the periodic table.
The mass number is the number of protons and neutrons in the atom.
The atomic number is the number of protons in the atom.
You can find the number of protons from the periodic table.
You can find the neutrons by subtracting the mass number by the number of protons in the atom.
Unless you have an ion, you will have the same amount of electrons as you do protons.
To write in nuclear notation, you write the chemical symbol with the mass number and atomic number shown in the attachment. It is preferable to have the mass number and atomic number directly above each other.

Answer:
a heterogeneous mixture
Explanation:
I can see all of the different parts of the frozen yogurt, and if I were to pick up a gummy bear, it would come out. Thus, it is not fully/completely mixed with the other components.
It is a heterogenous mixture.
What is the difference between Homogeneous and Heterogeneous Mixtures ?A type of mixtures where all the components are mixed uniformly called as homogeneous mixture.
Here the Particles are distributed in an uniform way, called as solution. Example rainwater, vinegar.
It consist of one phase, It can’t be separated out physically
In heterogenous mixture, all the components are completely and equally mixed, particles can be seen under a microscope.
Here the Particles are distributed non-uniform way, Example: seawater, pizza, etc.
