1. A sample of oxygen (0.) gas has a mass of 32.65 g and a volume of 24.924 L. What is the density of the 0,gas?​

Answers

Answer 1

Answer:

The answer is

1.31 g/L

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass of oxygen gas = 32.65 g

volume = 24.924 L

The density of the gas is

[tex]density = \frac{32.65}{24.924} \\ = 1.3099823463...[/tex]

We have the final answer as

1.31 g/L

What will most likely occur if sulfur forms an ionic bond with another element? (Click on the icon for the periodic table to view sulfur)

Sulfur will accept electrons.
Sulfur will donate electrons.
Sulfur will become a positive ion.
Sulfur will become less stable.

Answers

Answer:

The answer is Sulfur will accept electrons

Explanation:

Because it will most likely occur if sulfur forms an ionic bond with the elements

If sulfur forms an ionic bond with another element then the sulfur will accept electrons. Hence option A is correct.

What is ionic bond?

Due to their electrostatic attraction, oppositely charged species interact via ionic bonding, a form of chemical connection.

One atom transfers electrons to another when a positively charged ion forms a connection with a negatively charged ion.

Example: NA+ and Cl- gives NaCl

Sulfur belongs to group 6A of non-metals. Its valence electrons number six. It follows the octet rule. It must acquire two electrons. Thus, it creates two single covalent connections (ionic bonds).

When sulfur receives two electrons, it is ionized itself, so it from an ion with a 2-charge.

Sulfur will accept electrons will mostly likely occur if sulfur forms an ionic bond with another element. Hence option A is correct.

Changing the particles changes the atoms by converting it to a new substance through bond change.

During a chemical reaction changes occurs in the atoms of an element due to the formation or breaking of bonds.

There is either loss or gain or sharing of atoms between two elements reacting together.

Bonds between atoms break and new ones form and energy is either given out or taken in.

This type of reaction leads to the formation of new substances made up of a new combination of atoms and a different configuration of electrons.

Explanation:

Water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg

What is mass?

Mass is defined as a unit of measurement that describes the amount of matter that makeup an object.

It can also be defined as quantitative measures of inertia, fundamental properties of all matter. It is a dimensionless quantity.

As given 11.19% hydrogen is present in 1.2 x 10 kg

So, the mass of hydrogen = 11.198 % of 1.2 x 10 kg

                                           = 11.19 / 100 x 12

                                           = 1.32 kg

does water in a glass have mass

Answers

Answer:

A glass of water, or 200 grams of water, therefore contains 6.6855 × 1024 water molecules. The total mass of the hydrosphere is about 1.4 × 1024 grams, and thus the total hydrosphere contains about 7 × 1021 glasses of water (with 200 grams of water in each).

Explanation:

Answer:

Just like solids, liquids also have their own characteristic density. ... Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter. The density of a substance is the same regardless of the size of the sample.

Matter is generally defined as any thing that has mass and occupies spaces. Matter is generally divided into three categories ; solid, liquid and gas. Water is a liquid, water has does have molecules, thus has a mass, and is suspended in an area such as water in glass.

Object 1 is the heaviest object. Object 3 is heavier than Object 1. The weight is heavier than Object 2. The weight is the heaviest object.

Answers

Answer:

Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. ... Forces that cause a change in the motion of an object are unbalanced forces. Unbalanced forces are not equal and opposite.

Explanation:

Any push or pull is a force. To describe a force, you must know two things. You must know the size of the force and the direction of the force. Suppose two teams are playing tug of war. Each team is pulling with equal force, but in opposite directions. Neither team can make the other team move. Forces that are equal in size but opposite in direction are called balanced forces.

tug of war balanced

Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.

tug of war unbalanced 1

Unbalanced forces are not equal and opposite. Suppose that one of the teams in tug of war pulls harder than the other team. The forces would no longer be equal. One team would be able to pull the other team in the direction of the larger force.

Force and Motion

More than one force can act on an object at the same time. If you hold a paper clip near a magnet, you, the magnet and gravity all exert forces on the paper clip. The combination of all the forces acting on an object is the net force. When more than one force is acting on an object, the net force determines the motion of the object. In this example, the paper clip is not moving, so the net force is zero.

How do forces combine to form the net force? If the forces are in the same direction, they add together to form the net force. Suppose you and a friend are asked to move a piano for the music teacher. To do this, you pull on one end of the piano, and your friend pushes on the other end. Together, your forces add up to enough force to move the piano. This is because your forces are in the same direction. Because the forces are in the same direction, they can be added together to determine the net force. In this case, the net force is 45 N, which is plenty to move a piano - if it is on wheels, that is!

net force piano

If two forces are in opposite directions, then the net force is the difference between the two forces, and it is in the direction of the larger force. Consider two dogs playing tug of war with a short piece of rope. Each is exerting a force, but in opposite directions.

Notice below that the dog on the left is pulling with a force of 10 N, and the dog on the right is pulling with a force of 12 N. Which dog do you think will win the tug of war? Because the forces are in opposite directions, the net force is determined by subtracting the smaller force from the larger one. In this case, the net force is 2 N in the direction of the dog on the right. Give that dog a dog biscuit!

Answer:

A. Object 1 is the heaviest
