what are the differences between a solute and a solution
help giving 50 pointss
A solute is the substance that is being dissolved in a solution. It is the component of the solution that is present in the smaller amount. For example, sugar is a solute when it is dissolved in water to make a sugar solution.
A solution, on the other hand, is a homogeneous mixture of two or more substances. It is made up of a solvent, which is the substance that dissolves the solute, and the solute itself. In the example of sugar in water, water is the solvent and sugar is the solute.
In summary, a solute is one of the components of a solution and a solution is a homogeneous mixture of two or more substances.
Answer:
a solute is dissolved to find a solution
Explanation:
An element has a mass of 39.2 and an atomic number of 19. How many protons does this element have? How many neutrons? How many electrons?
Answer:
19 protons, 19 electrons, and 3 neutrons
Explanation:
the atomic number is 19 so the protons are the same, 19, and the electrons are the same as the proton, because protons are positive and electrons are negative so they have to balance out and the neutrons ➗ mass number by the atomic number.
What we eat, and how we move our bodies, effects our blood. How does that end up affecting our other organs in the body
Answer:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

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.

p.s. I'll mark the first answer the brainliest if it is correct! ;)
a. The atom’s volume increases.
b. The atom’s mass increases.
c. The atom becomes positively charged.
d. The atom becomes negatively charged.
c. The atom becomes positively charged
if the electrons are removed it means theres no longer a negative charge to balance the positive charge of the protons in the atom

A 5 g sample of pure gold has a density of 19.3 g/ml. Your friend purchased a gold ring that was made of 25 g of pure gold. What is the density of the ring?
Answer:
96.5 g/ml
Explanation:
If 5g is 19.3 then 25g is 19.3x5 which is 96.5 g/ml
The 5 g gold sample is having a density of 19.3 g/ml. The density for 25 g pure gold will be 96.5 g/ml.
What is density?Density of a substance is the measure of its mass per unit volume. It describes how closely the particles are packed within the substance. Density is dependant on bond type, temperature, pressure etc.
The density is the ratio of mass to the volume. The density of the 5 g sample is given 19.3 g/ml . Then the density for the mass 25g is determined with the relation as shown here:
M 1 D2 = M2 D1.
D2 = M2 D1/ M1
Now, the density of the 25 g gold ring is calculated as follows:
(25 × 19.3 )/5 = 96.5 g/ml.
Therefore, the density for the gold sample with 25 g mass is 96.5 g/ml.
