if you observe a first quarter on January 3 on what date will you see a full moon?
Answers
if you observe a first quarter on January 3, the date will you see a full moon is on February 1st.
What is the full moon about?The lunar phase during which the Moon is completely illuminated from Earth's perspective is known as the full moon. When Earth is situated halfway between the Sun and the Moon, this happens. This indicates that the near side of the moon, which faces Earth, is fully illuminated by the sun and appears as a roughly circular disk.
The Moon is a symbol for both the emotional and physical bodies. The full Moon is a time to be open and receive the spirit's light and awareness into your physical, emotional, and mental bodies
It takes 29 day, to get to the full moon. This will be:
= January 3 + 29 days
= February 1st

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?
Answers
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.

Determine the pressure in atm exerted by 1 mole of methane placed into a bulb with a volume of 244.6 mL at 25°C. Carry out two calculations: in the first calculation, assume that methane behaves as an ideal gas; in the second calculation, assume that methane behaves as a real gas and obeys the van der Waals equation
Answers
The pressure in atm exerted by 1 mole of methane placed into a bulb with a volume of 244.6 mL at 25°C is 101.94atm.
How to calculate pressure?The pressure of an ideal gas can be calculated using the following formula:
PV = nRT
Where;
P = pressure V = volumen = number of molesR = gas law constantT = temperatureAccording to information in this question;
T = 25°C = 25 + 273 = 298KV = 244.6mL = 0.24LR = 0.0821 Latm/KmolP × 0.24 = 1 × 0.0821 × 298
0.24P = 24.47
P = 24.47/0.24
P = 101.94atm

10) What volume of oxygen at STP must react with 5.8 L of hydrogen to form water?
(Hint: write and balance the reaction first)
The answer is 2.9L (I NEED THE STEPS)
Answers
2.9 L of oxygen are required to react with 5.8 L of hydrogen at STP to form water.
What is the balanced equation of the formation of water?Hydrogen gas and oxygen gas combines in a molar volume ratio of 2 : 1 to form water.
The equation of the reaction is given as follows:
2 H2O + O2 ----> 2 H2OThus, twice the volume of hydrogen is required with a given volume of oxygen to form water.
If 5.8 L of hydrogen is available for reaction at STP, the volume of oxygen required all be half of 5.8 L.
Volume of oxygen required = 5.8 / 2 = 2.9 L
Therefore, 2.9 L of oxygen are required to react with 5.8 L of hydrogen at STP to form water.

Calculate the freezing point and boiling point of each aqueous solution, assuming complete dissociation of the solute.
a. 0.100 m K2S
b. 21.5 g of CuCl2 in 4.50 * 102 g water
c. 5.5% NaNO3 by mass (in water)
Answers
The freezing points of each of the solutions are as follows;
0.100 m K2S - - 0.558oC
21.5 g of CuCl2 in 4.50 * 102 g water - -2oC
5.5% NaNO3 by mass (in water) - - 2.6oC
What is freezing point?The freezing point is the point at which liquid changes to solid. Let us now look at the freezing point of each solution.
a)
Since;
ΔT = K m i
K = 1.86 oC m-1
m = 0.100 m
i = 3
ΔT = 1.86 oC m-1 * 0.100 m * 3 = 0.558oC
Freezing point = 0oC - 0.558oC = - 0.558oC
b) Number of moles of CuCl2 = 21.5 g/134.45 g/mol = 0.16 moles
molality = 0.16 moles/0.45 Kg = 0.36 m
ΔT = K m i
ΔT = 1.86 oC m-1 * 0.36 m * 3 = 2oC
Freezing point = 0oC - 2 = -2oC
c) Number of moles of NaNO3 = 5.5g/85 g/mol = 0.065 moles
molality of the solution = 0.065 moles/0.0945 Kg = 0.69 m
ΔT = 1.86 oC m-1 * 0.69 m * 2 = 2.6oC

NEED HELP ASAP!!! As atmospheric carbon dioxide increases, the amount of carbon dioxide dissolved in the ocean _____.
Question 1 options:
increases
decreases
stays the same
Answers
Answer:
If temperature stays the same, the amount of carbon dioxide dissolved in the ocean would increase.
Explanation:
The carbon dioxide in the air ([tex]{\rm CO_{2}}\, (g)[/tex]) and the carbon dioxide dissolved in the ocean ([tex]{\rm CO_{2}}\, (aq)[/tex]) are in a solution equilibrium:
[tex]{\rm CO_{2}}\, (g) \rightleftharpoons {\rm CO_{2}}\, (aq)[/tex].
Assume that the concentration of carbon dioxide in the air ([tex]{\rm CO_{2}}\, (g)[/tex]) increased while temperature stayed the same.
By Le Ch[tex]^{}[/tex]atelier's Principle, the solution equilibrium [tex]{\rm CO_{2}}\, (g) \rightleftharpoons {\rm CO_{2}}\, (aq)[/tex] would shift to offset this increase in [tex]{\rm CO_{2}}\, (g)[/tex] concentration. Specifically, this equilibrium would reduce the amont of [tex]{\rm CO_{2}}\, (g)\![/tex] in the system by converting more atmospheric [tex]{\rm CO_{2}}\, (g)\!\![/tex] to [tex]{\rm CO_{2}}\, (aq)\![/tex] dissolved in the ocean. Therefore, the concentration of [tex]{\rm CO_{2}}\, (aq)\!\![/tex] dissolved in the ocean would increase.
