Bonding with intermolecular forces:
1.) is CH3F a hydrogen bonding? yes or no?
2.) is CH3F dipole-dipole interactions? Yes or no?
3.) is CH3F a london dispersion forces? Yes or no?
Explanation:
1.) is CH3F a hydrogen bonding? yes or no? = No, CH3F is not a hydrogen bonding beacuse the molecule lacks hydrogen atoms bonded to nitrogen, oxygen, or fluorine; ruling out hydrogen bonding.2.) is CH3F dipole-dipole interactions? Yes or no? = Yes, CH3F is a dipole-dipole interactions beacuse in it's molecule, there are no metal atoms to form ionic bonds3.) is CH3F a london dispersion forces? Yes or no?= Yes, CH3F is a london dispersion forces because in it's molecule, there are no metal atoms to form ionic bonds .The intermolecular forces present in the bonding of CH₃F are dipole-dipole interactions and London dispersion forces.
1.) No, CH₃F does not exhibit hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom such as fluorine, oxygen, or nitrogen. In CH₃F, the hydrogen atom is bonded to carbon, which is not highly electronegative.
2.) Yes, CH₃F exhibits dipole-dipole interactions. Dipole-dipole interactions occur between molecules that have permanent dipoles due to the electronegativity difference between the atoms. In CH₃F, the fluorine atom is more electronegative than the carbon and hydrogen atoms, resulting in a polar molecule with a permanent dipole moment.
3.) Yes, CH₃F exhibits London dispersion forces. London's dispersion forces, also known as Van der Waals forces, are present in all molecules and arise from temporary fluctuations in electron distribution. Although CH₃F has dipole-dipole interactions, it also experiences London dispersion forces due to the temporary shifts in electron density.
Hence, the bonding in CH₃F was explained above.

How many molecules of methane (CH4) do you need to burn in order to get 9.03 x 1023
molecules of carbon dioxide (CO2)? Avogadro's number is 6.02 x 1023 molecules/mol.
CH4 + O2 - CO2 + 2H2O
Answer:
9.03*10^23 molecules CH4
Explanation:
In the equation CH4 + O2 -> CO2 + 2H2O, the molar ratio of CH4 to CO2 is 1:1. It takes 1 mole of CH4 burned to form 1 mole of CO2. If we convert molecules to moles, we do 9.03 x 10^23 divided by 6.02 x 10^23 = 1.5 moles of CO2. Since we know the ratio is 1:1, that meant it would take 1.5 moles of CH4 burned to make that much CO2. So we convert our 1.5 moles of CH4 into molecules by multiplying 1.5 * 6.02 x 10^23 which equals 9.03*10^23 molecules CH4.

4. Calculate the total amount of heat a beaker of water would absorb sitting in the sun. The water has a mass of 500g, a specific heat of 4.184 (J/gx°C), and had a change in temperature of 22 °C.
Answer:
46024 j or 46.024 kj
Explanation:
500 gm * 4.184 j/(gm-C) * 22 C = 46024 j
The heat energy absorbed by water of mass 500 g and specific heat capacity of 4.184 J/°Cg with a temperature rise to 22 degree celsius is 46024 J.
What is specific heat capacity?Specific heat capacity of a substance is the heat energy required to raise the temperature of that substance by one degree celsius per mole. It is an intensive property and does not dependent on the total amount if the substance.
Specific heat capacity of a substance is a constant and water have this value of 4.184 J/°Cg. The heat energy q absorbed or evolved from a system is related to the specific heat capacity C , mass M and temperature change ΔT occured on the system as in equation written below:
q = mC ΔT .
The heat energy of water of mass 500 g absorbed for a temperature change of 22 °C can be calculated as follows:
q = 500 g × 22 °C × 4.184 J/°Cg
= 46024 J.
Hence, the total heat of absorption of water for the given mass and temperature change is 46024 J.

What is the specific heat of a mystery substance that requires 79 joules of energy to heat 4.52
grams of substance from 23 degrees Celsius to 54 degrees Celsius?
The specific heat of a mystery substance that requires 79 joules of energy to heat 4.52 grams of substance from 23 degrees Celsius to 54 degrees Celsius is 0.56 J/g°C.
How to calculate specific heat capacity?The specific heat capacity of a substance can be calculated using the following formula:
Q = mc∆T
Where;
Q = quantity of heat absorbed or released (J)m = mass of substancec = specific heat capacity∆T = change in temperature (°C)c = Q/m∆T
c = 79 ÷ 4.52 × (54 - 23)
c = 79 ÷ 140.12
c = 0.56 J/g°C

C. 760.0 mm of Hg
D. 570.0 mm of Hg
Answer:

Explanation:

1 atm is 760 mm hg
2.25 * 760 = 1710 mm HG
Answer:
[tex]\huge\boxed{\sf 2.25\ atm = 1710\ mm\ of\ Hg}[/tex]
Explanation:
Partial pressure of gas A = 0.75 atm
Partial pressure of gas B = 0.25 atm
Partial pressure of gas C = 1.25 atm
Total partial pressure = 0.75 atm + 0.25 atm + 1.25 atm
= 2.25 atm
We know that:
1 atm = 760 mm of Hg
Multiply 2.25 to both sides
2.25 atm = 760 × 2.25 mm of Hg
2.25 atm = 1710 mm of Hg

The solubility of magnesium fluoride, , in water is g/L. What is the solubility (in grams per liter) of magnesium fluoride in 0.29 M of sodium fluoride,
Answer:
1.457*10^-8 grams
Explanation:
First we want to find the molar concentration of MgF2. We can do this by dividing 0.016 (the solubility in grams of MgCl2 in a litre of water) by its molar mass (approx. 62.3 grams). Thus, the molar solubility of MgF2 is 2.57*10^-4 M.
Next, we must calculate the Ksp of MgF2. The equilibrium expression is:
MgF2⇄Mg+2F
Thus [tex]Ksp=[Mg^+][F^-]^2[/tex]
This means that, in equilibrium, there are 2.57*10^-4 M of [tex]M^+[/tex] and 5.136*10^-4 M of [tex]F^-[/tex]
Plugging in the above information, our Ksp for MgF2 is approximately 6.78*10^-11
Next we will need to use the RICE table. Since there is already 0.29M of NaF dissolved, there is initially 0.29M of [tex]F^-[/tex].
R: MgF2 ⇄ [tex]Mg^{+}[/tex]+2[tex]F^-[/tex]
I: N/A 0 0.29M
C: N/A +x +x
--------------------------------------------
E: N/A x 0.29+x
To make calculations easier, we will assume that 0.29+x≈0.29
This means that Ksp=0.29x=6.78*10^-11
Therefore, x≈2.338*10^-10M
Multiply that by 62.3 and we get around 1.457*10^-8 grams.

Answer:
the answer has been given below have a good day
Explanation:
mark as brainiest
The species are present at 10-6 mole/L or greater when dissolved in water is when in solutions, weak acids and bases partially ionize.
What is ionization?Ionization is defined as anything that causes electrically neutral atoms or molecules to gain or lose electrons in order to become electrically charged atoms or molecules (ions). One of the main mechanisms by which radiation, including charged particles and X-rays, transmits their energy to matter is ionization. An anion is created when an atom or molecule picks up an electron; a cation is created when they lose an electron.
Weak Acids and Weak Bases Ionizing. Numerous acids and bases are weak, meaning they do not completely ionize in aqueous solution. The nonionized acid, hydronium ion, and conjugate base of a weak acid are all mixed together to form a solution in water, with the nonionized acid being present in the highest concentration.
Thus, the species are present at 10-6 mole/L or greater when dissolved in water is when in solutions, weak acids and bases partially ionize.
