What is the pH of a solution with a (H+] = 0.80 M? *Please round your answer to the appropriate number of significant figures. Your answer can be in standard notatic "e" in place of x10.*
Answer:
The pH of a solution with a (H+] = 0.80 M is [tex]9.6 e^{-2}[/tex]
Explanation:
As we know
pH = -[log H+]
Substituting the value of H+ ion concentration in the above equation, we get -
pH = -log [0.80]
pH [tex]= -[-0.096] = 0.096 = 9.6 e^{-2}[/tex]

how would I solve this problem?
Answer:
D
Explanation:
The goal in this set up is to make sure all units cancel each other.
Since we need to go from grams to atoms, our final unit should be atoms.
Using method of elimination, let's see why other options are wrong.
A - Although 'g' is cancelled out, we are left with moles^2 / atoms
B - Although 'g' is cancelled out, we are left with moles^2 / atoms
C - Although 'mol' is cancelled out, we are left with g^2 / atoms

When 10 grams of water completely evaporate into water vapor, the volume of the water vapor is greater than the volume of the original liquid water, but the mass remains the same. Why does the mass stay the same? Which answer is correct?
A
The temperature of the liquid water and water vapor is the same.
The temperature of the liquid water and water vapor is the same.
B
The density of the liquid water is the same as the density of the water vapor.
The density of the liquid water is the same as the density of the water vapor.
C
The number of atoms in the water vapor is equal to the number of atoms in the liquid water.
The number of atoms in the water vapor is equal to the number of atoms in the liquid water.
D
The distance between the water molecules is the same in the liquid and the vapor.
The distance between the water molecules is the same in the liquid and the vapor.
Answer: I think the answer is B or C, its kind of hard.
As the number of atoms in the water vapor is equal to the number of atoms in the liquid water. Therefore, the mass of the water remains the same.
What is evaporation?Evaporation is a process that usually happens on the surface of water or liquid and it involves the conversion of the liquid phase into the gaseous phase. This process involves a change in the state of matter of water or liquids.
When the water is completely evaporated into water vapor the density of the water vapor is less than the density of the liquid water as the vapors occupy a large volume in comparison to liquid water.
But the number of atoms in the water vapor is the same as the number of atoms in the liquid water. The mass of the water is due to the mass of the atoms.
Therefore, the mass of the water remains the same during the phase transition from liquid water to water vapors. Therefore, option (C) is correct.

Explanation:
why is respiration considered an exothermic process
Answer:
Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.
Explanation:
Good Luck!
Respiration is considered as an exothermic reaction because, in the respiration process, oxidation of glucose takes place which produces a large amount of heat energy stored in the form of ATP. This is shown in the following chemical equation C 6
What is the primary difference between a molecule and a compound?
A. All molecules are compounds, but not all compounds are molecules
B. Molecules always contain only one type of atom, unlike compounds
C. Compounds must be composed of more than one type of atom
Answer:
A. "All molecules are compounds, but not all compounds are molecules"
Explanation:
An example of a compound-molecule is oxygen. The elemenal is O, because the periodic table isn't describing molecules, it's describing atoms. The molecule is O2 because it takes 2 O atoms to make a molecule of oxygen.
The primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom'.
Explanation:
A molecule is a group of atoms of the same or different types of atoms bound to each other.Molecules are the smallest unit of a substance that possesses the characteristic of the substance.A compound is a substance in which two or more different types of atoms are bound to each other.In compounds, atoms of different elements are in a fixed proportion.So, from this, we can conclude that the primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom'.

1. If you have 5g of pennies how many dozen pennies do you have?
Answer:
15.69 dozen
Explanation:
Mass of penny = 5 g
Dozens of penny =..?
Next, we shall convert 5 g to gross. This can be obtained as follow:
3824 g = 1000 gross
Therefore,
5 g = 5 g × 1000 gross / 3824 g
5 g = 1.3075 gross
Thus, 5 g is equivalent to 1.3075 gross.
Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:
1 gross = 12 dozen
Therefore,
1.3075 gross = 1.3075 gross × 12 dozen / 1 gross
1.3075 gross = 15.69 dozen
Thus, 5 g of penny is equivalent to 15.69 dozen

How many moles of I2 are in 8.23 moles of NaI ?
Answer: 4.12
Explanation:
we know that the given mol is 8.23 mol and they are 2NaI and I2 so we will write the equation like this.
8.23mol NaI x 1mol of I2 ÷ 2molNaI = 4.115≅ 4.12 mol of I2
we placed NaI at the bottom to cancel out with the 8.23 mol of NaI

1)Change the following temperatures to Kelvin: 100 C and -20 C
2)Change the following temperatures to Celsius: 273 K and 15 K
Answer:
373 K; 253 K
0°C ; -258°C
Explanation:
In order to change Temperatures to Absolute Value (Kelvin) you shoud do this sum:
T° in C + 273 = T° in K
For question 1:
100°C + 273 = 373K
-20°C + 273 = 253K
For question 2:
T° K - 273 = T° C
273 K - 273 = 0°C
15 k + 273 = -258 °C
Answer:
-67.8
