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]

The process of water changing from a liquid to solid is called?
Answer:
freezing
Explanation:
When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt. ... The reverse of the melting process is called freezing. Liquid water freezes and becomes solid ice when the molecules lose energy.
hope it becomes helpful to you ☺️☺️

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.
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

High-speed winds transfer more energy to the ocean’s surface, creating bigger waves.
Question 10 options:
True
False
Answer:
I think that would be true. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing
Answer: True.
Explanation: Yes, waves get energy from the wind through friction, so you see those waves get bigger each time. The longer the winds blows, the more friction, and energy it's getting, meaning better, and deadly waves. The wind can sometimes cause tsunamis if the its blowing too hard.

Which has the larger change hydration in each pair of a)Na+ Or cs+ b)Sr+2 or Rb+ c)Na+ or Cl- d) O-2 or F- e)OH- or SH-
Answer:
See explanation
Explanation:
The size of the hydration enthalpy of a system depends on the attraction between the ions and the water molecules. Stronger attractions exist between water and smaller ions. The smaller the ion, the higher the hydration enthalpy is.
In the first pair, Na+ is smaller than Cs+ hence Na+ has a larger change in hydration enthalpy.
In the second pair, Sr2+ is smaller than Rb+ hence Sr2+ has a larger change in hydration enthalpy.
In the third pair, Na+ is smaller than Cl- hence Na+ has a larger change in hydration energy.
F- is smaller than O2- hence F- has a larger change in hydration energy.
OH- is smaller than the SH- hence the OH- has a larger change in hydration energy.
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.

True or false: All molecules or atoms in a substance have the same amount of kinetic energy at a given temperature?
Answer:
false
Explanation:
Difference in neutrons in a molecule means that molecules have different masses. They will always have different energies
another example: water has less energy as a liquid than as a gas
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:
2.3 X 10^24 atoms CO2
Explanation:
Answer:
2.30 x10²⁴ molecules CO2
Explanation:
Convert mass of CO2 to moles
Convert moles of CO2 to molecules using Avogadro's number.
168.2 g CO2 x 1 mole CO2 / 44 g CO2 x 6.022 x10²³ molecules CO2 / 1 mole CO2
= 2.30 x10²⁴ molecules CO2
