Imagine that you have 100g of water.
You start dissolving KNO3 in the water and you find that after you've dissolved about 55 g of KNO3, you can't dissolve any more; it just sinks to the bottom.
Approximately what is the temperature of the water?
Round your answer to the nearest whole number and submit the number only; no units.
Answers
Answer:
Explanation:
So, just find 55 on the solubility side and with your finger just move to the right untill you touch the line you should get in between 46-48. I would go more for 48.
Hope you have a wonderful day!

Which of the following factors does NOT affect surface currents?
A. Coriolis effect
B. density
C. continental deflection
D .wind
Answers
Explaining: surface currents are caused by wind density affects deep ocean currents
The only factors that doesn't affect surface current from the question is B:
density.
Surface currents can be regarded as current that is been formed as a result of Earth's rotation as well as changes in temperature.Surface currents is know as one of the determinant for climate. These currents is responsible for the bringing of warm water from the equator then transfer it to the cooler parts of the ocean as a result of this heat energy is transferred.Some factors that influence surface current are; Coriolis effect : This also aid the movement of the currentcontinental deflection : this helps the deflection of the currents from the continental land masses.wind : without wind there cannot be transfer of the warm water from the equator to the part of the ocean that is cool.Therefore, Option D is correct because density does affect the surface current.

Most representative metal atoms tend to gain enough electrons to attain a stable noble gas (octet) configuration.
True or False
Answers
Answer:
False
Explanation:
Non- metals tend to gain electrons easily, metals tend to lose electrons easily
For example, oxygen, a non-gas, when it is an ion, has the option to lose 6 electrons to become like helium, or gain 2 electrons to become like the noble gas neon. However, it becomes like neon for 2 reasons.
A. As a general rule, atoms lose/gain the LEAST amount of electrons.
B. Oxygen is a nonmetal, therefore, to become like a Noble Gas, it would gain, as non-metals usually would, 2 electrons.

Answers
Answer:
Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion. Some materials diffuse readily through the membrane, but others require specialized proteins, such as channels and transporters, to carry them into or out of the cell.

A medallion was dropped into 20.0 mL of water. The water level rose to 25.3 mL. What is the volume of the medallion? (Vobj = Vf - Vi)
Answers
Answer:
5.3 mL
Explanation:
We solve this problem using Archimede's principle, which states that the volume displaced by a submerged object is equal to the volume of the object.
With that in mind we calculate the volume of water displaced by the medallion:
25.3 mL - 20.0 mL = 5.3 mLAs the medallion displaced 5.3 mL of water when submerged, the volume of the medallion is also 5.3 mL.
The Big Bang Theory is a hypothesis that states that all matter
and energy were at one time compressed into a small volume
and then _________
Answers
Answer:
I’m not sure how they want you to answer the fill in blank.
Explanation:
The Big Bang is a theory where 14 billions years ago all matter and energy in the universe was compressed into an extremely small volume that exploded and began expanding in all directions.
The big bang theory is a hypothesis that states that all matter and energy were compressed into a small volume at one time and then expanded outward.
What is Big Bang Theory?The big bang model of the universe can be described as the model to identify the beginning of the universe. The big bang model is a cosmological model which is described by the software development life cycle.
The Big Bang theory is the dominant model of the observable universe from its beginnings to large-scale evolution. This model explains how the universe is expanded from a state of high density and temperature. It provides an explanation for phenomena, such as cosmic microwave background radiation, the abundance of light elements, and large-scale structure.
Due to the big bang as we know, the universe has been created existing about 12 - 15 billion years ago. According to the theory that the Big bang was a gigantic explosion that formed all of the energy and mass in less than a second in the universe.

which element has the highest electrical conductivity (h) (Mg) (CL) (He)
Answers
4. He
Conductivity is the measure of the ease at which an electric charge or heat can pass through a material.A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy.Electrical conductivity tells us how well a material will allow electricity to travel through it.Usually metals are good conductors of electricity.1. Chlorine is a non metal thus it will have the lowest electrical conductivity.
2. As a plasma, helium's electrons and protons are not bound together, resulting in very high electrical conductivity, even when the gas is only partially ionized.
3. Hydrogen is also electrically conductive above certain temperatures.
4. Since, magnesium is a metal thus it is also electrically conductive in nature but less than hydrogen and helium.
Therefore, Helium will have the highest electrical conductivity.
