Answer:Molarity can be used to calculate the volume of solvent or the amount of solute. The relationship between two solutions with the same amount of moles of solute can be represented by the formula c1V1 = c2V2, where c is concentration and V is volume.
Explanation: c1V1 = c2V2
The equation that can be used to solve the volume of a solution using the molarity equation is:
Molarity (M) = moles of solute (mol) / volume of solution (L)
This equation can be rearranged to solve for the volume of solution:
Volume of solution (L) = moles of solute (mol) / Molarity (M)
By knowing the molarity of the solution and the number of moles of solute, you can substitute these values into the equation to calculate the volume of the solution.
It's important to note that this equation assumes the molarity is given in units of moles per liter (mol/L). If the molarity is given in a different unit, it may need to be converted before using the equation.

On August 4, 2020, an explosion estimated at 1.2 kilotons of TNT (dynamite) destroyed
a port in Beirut, Lebanon. The sound from the explosion travelled at 767 mph (the speed
of sound). How long, in seconds, did it take for the sound to travel 50 km?
Answer:
it will take that explosin 15.34 millisecond

Why would early Earth have been toxic for modern day animals? Why were cyanobacteria able to
survive
Answer: The surface of early earth was mostly molten and volcanic. The atmosphere was hot and highly toxic.
Explanation: Photosynthetic organisms were present when earth was primarily anoxic. photosynthetic organisms were present when earth was primarily anoxic. the early forms of photosynthesis did not produce oxygen as a waste product. cyanobacteria carry out anoxic photosynthesis. the early forms of photosynthesis did produce oxygen, but it was not enough to make a difference in the atmosphere. the early forms of photosynthesis were carried out in the water, and there was no way for the oxygen to move into the atmosphere.
1
Early earth have been toxic for modern day animals as at that time atmosphere is oxygen free, and cyanobacteris is able to survive due to symbiosis.
What are cyanobacterias?
Cyanobacteria is a group of microorganisms that are related to bacteria but can perform photosynthesis. They are prokaryotic and are thought to be the earliest form of life on the planet.
Early earth atmosphere may proof toxic for modern day animals because at the earliest time, atmosphere is oxygen free means no oxygen is present in the atmosphere. And in the today scenario we can't imagine life without oxygen.
Cyanobacteria were able to suvive in that early atmosphere through alternative option like symbiosis in which a cell merges with another cell in order to the survival of both cells.
Hence life is toxic at the early time because of the absence of oxygen.

is the study of matter and energy ,and the interactions between the two through forces and motion
The study of matter and energy ,and the interactions between the two is through forces and motion which is a part of physics.
What is motion?Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.
Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.
Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic mechanics is based on modern kinematics.

You are throwing a pizza party for 15 people and figure that each person will eat 4 slices. You call the pizza place and learn that each pizza will cost you $14.75 and it will be cut into 12 slices. How much is the pizza for this party going to cost you? Give the answer to the nearest cent.
Answer:
15 people x 4 slices so you’ll need 60 pieces
60/12(the amount of slices per pizza) =5
You need 5 pizzas. $14.78 x 5 = 73.90.
Explanation:
the answer is that one 73.90 is rounded nearest cent : ) took me a while to get it
Answer:
the cost of pizza for 15 people is $73.9
Explanation:
a pizza party for 15 and each person will eat 4 slices.
meaning the 15 people will eat 4 x 15 = 60 slices
Since each pizza will cost you $14.78 and will be cut into 12 slices.
`1 pizza = 12 slices = $ 14.78
60 slices = (14.78 x 60) / 12 = 886.8 /12 = $73.9the cost of pizza for 15 people is $73.9

a chemical property.
c. physical property.
b. extensive property.
d. chemical change.
Answer:
d
Explanation:
The measurement of boiling point is a physical property it involves only physical changes and not any chemical change. Hence, option c is correct.
What is physical properties?Physical properties of a substance include properties such as boiling point, melting point, density, mass, solubility etc. These are all characterised with a change in physical state of the substance and not any chemical reactions.
Boiling point of a substance is the temperature at which the substance converts from its liquid state to vapor state where the vapor pressure of the gas phase above the liquid is equal to the atmospheric pressure.
Boiling of a substance does not involve any making or breaking of chemical bonds and not producing a new compound. Therefore, boiling point is a physical property.

Boiling point
Explanation:
Distillation is one of the most widely used separation technique in chemistry. It is used to separate a mixture of liquid substances with different boiling point. Hence, the basis of the separation is BOILING POINT DIFFERENCE.
In the procedure, the liquid substances are heated until they turn gaseous, which they do at different times considering their different boiling points. The separated components are then converted back to liquid states in a process called CONDENSATION.
