#6).
Every 1,000 mL makes 1 L
How many 1,000mL are there in 2,800 mL ?
That's division.
   (2,800 mL) / (1,000 mL) = 2.8 L

#7).
The 'perimeter' means the 'distance all the way around'.
You have to know that both sides of a rectangle are the same length,
and also the top and bottom are the same length.
So the perimeter of this rectangle is

   (2 yd) + (4.5 yd) + (2.yd) + (4.5 yd) = 13 yd .

Oops. The problem wants to know the perimeter in feet.
So you have to know that each yard is the same as 3 feet.
In order to find the number of feet in 13 yards, you have to
take 3 feet 13 times .

   (3 feet) times (13) = 39 feet .

#8).
For this one, you have to know that every 36 inches makes 1 yard.

How many 36 inches are there in 48 inches ?
That's division.
   (48 inches) / (36inches) = 1 and 1/2 yards .

#9).
For this problem, you have to know how to handle a mixed number,
and you also have to know that there are 16 ounces in 1 pound.

Add up the fruit:

             (3-1/2 pounds) + (4 pounds) + 2 pounds) = 9-1/2 pounds

Now, remember that each pound is the same as 16 ounces. So if you
want to find the number of ounces in 9-1/2 pounds, you have to take
16 ounces 9-1/2 times .

     (16 ounces) times (9-1/2) = 152 ounces.

#10).
This one is just adding up some numbers. But after you finish doing that, you have to know that 1,000 meters is called '1 kilometer' .

Add up the distances that Omar ran:

   (1,000 meters) + (1,625 meters) + (1,500 meters) = 4,125 meters

The problem wants to know how many kilometers this is, so you have to figure out how many '1,000 meters' fit into 4,125 meters.

That's division.

   (4,125 meters) / (1,000 meters) = 4.125 kilometers

Explain how scientific advancements have lessened the effects of hazardous events on society.

Answers

Answer:

Scientific advancements can detect some harmful events before they occur and it allows the society to plan for them, thereby reducing the risk of damage that occurs.

Explanation:

Scientific advancements reduce the natural disasters level in a region by evaluating the physical and chemical characteristics of the land.

Also, it develops new medical terminology and concepts that reduce the spread of hazardous diseases in society.

Satellites are used to predict the weather report and by using this report proper precautions can be taken at the time of floods and storms.

Construction of dams and canals highly reduced the risk of water overflowing in the lands.

Answer: Scientists are able to detect and predict some hazardous events through scientific advancements. By detecting these events early, society can prepare for the events, thereby reducing the amount of damage to people and property caused by the hazardous event.

HELP ASAP 20 PTS!!!Fireworkium (Fw): This element has 15 protons and 15 electrons in its neutral atom.

Toothium (T): This is a nonmetal with an average atomic mass number close to 19.

Floatium (Fl): This is a gas that the aliens often use to fill balloons and blimps. It contains two protons in its nucleus.

Breathium (Bt): This element is a nonmetal and has one less proton than an atom of Toothium and has an atomic mass close to 16 amu.

Lightium (Lg): This is a gas that does not react with other elements. It glows when it is heated in a lamp or vacuum tube. It contains one more proton in its nucleus than Toothium.

Rottoneggium (Re): This is a nonmetal with one less electron than Mustarium. It has a total of 16 electrons in its electron cloud.

I honestly don't understand

Answers

Basically they are asking you to find the element that is most closely associated with these clues.

1. Fireworkium: 15 protons and 15 electrons? No problem. We can see that the atomic number is 15, in which in real life, the element is Phosphorous. (Phosphorous is a common element in fireworks for an explosive personality and colors)

2. Toothium: A nonmetal with average mass number close to 19? We check the periodic table once more and find that Fluorine is our answer. (Notice that fluorine is in toothpaste, which is why they decided the name Toothier)

3. Breathium: Now honestly, I didn't even have to check the periodic table but just realize that we breath Oxygen. But if you want the straight answer, Oxygen is a nonmetal which has an atomic mass close to 16, and surprise, it has one less proton than Fluorine.

4.Lightium: Immediately we see that since this gas does not react with other elements, it is a noble gas. If it glows in a lamp or vacuum tube, we can also see it is of a light origin. If it has one more proton than Toothium (Fluorine) than we can immediately see that in the periodic table, our answer is Neon.

5. Rottoneggium: We can immediately guess sulfur. The straight way shows that it has 16 electrons, and the non-ion atom should also have 16 protons. Therefore, our answer is Sulfur.

6. I just realized I forgot Floatium: If it has 2 protons, we look in the periodic table and see that our answer is Helium.

Which of the following pairs correctly represents A and B in the image above?A – solvent and B – solute
A – solute and B – solvent
A – solute and B – solution
A – solvent and B – solution

Answers

A is marking the solvent molecules which is marked in blue. And B is marking the whole solution.

Option C

Explanation:

A solution is defined as the homogeneous mixture of a solute in a solvent in a range of concentration where generally solvent is more in amount than in solution.

A solute is the component of the solution which is generally less in amount and is homogenously mixed with the solution. Here they are marked in blue. And the molecules that are representing the solvent are marked in orange colour. The solute and the solvent total makes the solution which is marked by B.

What happens when a pure substance undergoes a chemical change

Answers

When a pure substance undergoes chemical change, the pure substance changes in chemical composition.

What is a chemical change?

Chemical change is any change that involves the formation of new substances or products and it is not easily reversible.

A pure substance is any substance that has a definite chemical composition.

However, when a pure substance undergoes chemical change, the chemical composition of the substance is changed to form new products.

The substance changes completely. It undergoes a chemical reaction.

Example is when you bake a cake. You cannot bring it bake to dough.
