Answer;

- A 100 mL graduated cylinder since it has marks showing the volume of the substance measured.

Explanation;

-A graduated cylinder or a measuring cylinder is a common piece of laboratory equipment used to measure precise volumes of a liquid.

-Graduated cylinders are specifically designed to measure out liquid volumes. Their tall narrow design makes for a more precise reading of the liquid level as compared to other pieces used to measure volume.

Describe the major types of bodies of water

Alina [70]

<h2>Answer and Explanation </h2>

The body of water means the occurrence of water on earth’s surface. Examples are oceans, lakes, seas, ponds, and pools. The major bodies of water are:

Pacific ocean is the biggest and deepest of Earth's oceanic divisions. It stretches from the Arctic Ocean in the direction to the Southern Ocean.

Atlantic ocean is another giant of the world's oceans. It includes nearly 20 percent of the Earth's exterior and nearly 29 percent of its water covering space.

The Indian Ocean is the third largest Ocean in the world. It is surrounded by Asia, Africa, and Australia.

Arctic ocean is the smallest and shallowest of the world's five main oceans.

This diagram shows the forces acting on a car. The center dot represents the car, and the arrows represent the forces acting on

Mariulka [41]

Answer : The correct option is B- Towards the left.

Solution : Given,

Force on car in upward direction, $F_1$ = 6000 N

Force on car in downward direction, $F_2$ = 6000 N

Force on car in right direction, $F_3$ = 5000 N

Force on car in left direction, $F_4$ = 6000 N

Force : Force is equal to the mass multiplied by the acceleration. The force is directly proportional to the acceleration.

Formula : F = m × a

where, F is force, m is mass and a is acceleration.

From the given diagram we conclude that the $F_1$ and $F_2$ are in opposite direction and the force acting on car are same. So, their net force is zero.

And in case of $F_3$ and $F_4$ , the net force will not be zero because force acting on car are different. The car will accelerate towards left direction because $F_4$ is higher than the $F_3$ .

So, the car will accelerate towards left direction.

#1: The element that loses electrons in a chemical reaction is said to have been which of the following?

Mrrafil [7]

#1: The element that loses electrons in a chemical reaction is said to have been which of the following? A. reduced

B. oxidized

C. combusted

D. rusted

**idk, is it reduced or oxidized??

Answer: oxidized. The element that loses electrons increases its oxidation number (becomes more positve or less negative) and this is oxidation.

Which type of reaction occurs if one element gains electrons and another loses electrons?

A. combustion

B. synthesis

C. oxidation-reduction

D. double-displacement

**my answer: C

Yes, oxidation-reduction

#3: What is the oxidation number for phosphorus in H4P2O7?

A. +5

B. +3

C. +1

D. - 1

**my answer: A. +5

This is the way to calculate it 4(+1) + 2x + 7(-2) = 0 => x = +5

#4: What is the oxidation number for phosphorus in Na2HPO3?

A. +5

B. +3

C. +1

D. - 1

**my answer; B. +3

is that right??

Right

2(+1) + 1 + x + 3(-2) = 0 => x = 6 -1 -2 = 3 (positive)
