what is the volume of an object with a mass of 50.0 and a density of 10.0
Answer:
5 or 5.0
Explanation:
because in order to find the volume yo divide mass and density
so 50.0 or 50 divided by 10.0 or 10 is 5
hope this helped :)
Answer:
5
Explanation:
You have to divide mass/density to get volume. In this case, 50/10=volume (which is 5).

Boiling point is the temperature at which a liquid changes its state from liquid to gas by vaporizing, usually at a constant temperature and pressure.
At the boiling point, the vapor pressure of the liquid becomes equal to the pressure of the atmosphere or the external pressure applied to the liquid surface, causing bubbles of vapor to form within the liquid and rise to the surface.

How can I associate Newton's three laws in the phenomenon?
Answer: In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

There are 2 main types of _______. One is a _______, where electrons are shared between atoms. The other is an _______, where one atom loses an electron to become a _______ charged ion, and the other atom gains the elctron to become a _________ charged ion.
Hello..!
There are 2 main types of ions one is an atom where the electrons are shared between the atoms. the other is an electron where one atom loses an electron to become a neutral in a charged ion, and the other atom gains the electron to become a charged lon anion.
\( \sf \red {\underline{ \underline{Explantation:}}}\)
Ions with a positive charge are known as cations. Those that are negatively charged are called anions.
¿Doubts? in the comments Greetings.
The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons.

What happened when the two substances were combined together in the cup? (highlight one)
The substances changed into different substances.
The substances did not change into different substances.
I am not sure if the substances changed into different substances.
Explain your answer using evidence from the Sim.
Based on evidence from Sim, when two substances were combined they did not change into different substances.
Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.
They just combine together and form a new substance.
Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.
The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.
Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.
If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.
It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.
