Answer:
The first ionization energy for K is less than Ca because Ca has a larger effective nuclear charge.
Answer: C. Salt and Water
Explanation:
The reaction between an acid and a base will have salt and water as its end product. This process is known " Neutralization Reaction".
HCl + NaOH -----------> NaCl + H2O
Hydrochloric Sodium Sodium Water
Acid Hydroxide (base) Chloride(Salt)
Answer:
i would assume that it would be (a)
Explanation:
The Sun generates its energy by nuclear fusion
NUCLEAR FISSION is when the heavy atom is split
fusion energy is scientifically feasible. Plasma conditions that are very close to those required in a fusion reactor are now routinely reached in experiments
mass gets lost is nuclear fusion
so (a) is the most accurate
The intermolecular forces that are responsible for the dissolution of Ethylene glycol in water is hydrogen bonding dipole-dipole forces and dispersion forces.
Both ethylene glycol and water contains the pair of hydrogen and oxygen.
The hydrogen of one atom create a bond with the oxygen of other atom this results in the formation of intra molecular hydrogen bonding.
The electron are non uniformly distributed over the molecule or the atom which results in the fluctuation of the electron density in the atom.
So it creates are dispersion forces which is present all over the molecule this forces helps to increase the strength of the bond formed between the ethylene glycol and water because they have large masses.
Both ethylene glycol and water are polar molecules because of being polar they form dipole and the dipole of both the molecules interact with each other in order to form bond between the atoms which eventually results in the formation dissolution of ethylene glycol in water.

Answer:
D. 0.36 g
Explanation:
When a gas is collected over water, the total pressure is the sum of the pressure of the gas and the pressure of the water vapor.
Ptotal = Pwater + PN₂
PN₂ = Ptotal - Pwater = 730 torr - 23.76 torr = 706 torr
We can find the mass of N₂ using the ideal gas equation.
