Answer:- 44.01 gram per mol.

Solution:- Mass of one mole means the formula mass of the compound. Carbon dioxide has one carbon and two oxygens.

So, formula mass of carbon dioxide = atomic mass of C + 2(atomic mass of O)

Atomic mass of carbon is 12.01 and atomic mass of O is 16.00. So, formula mass of carbon dioxide = 12.01+2(16.00)

= 12.01+32.00

= 44.01

So, the mass of one mole of carbon dioxide is 44.01.

A neutral atom has equal number of protons and electrons. A +ion or cation is an atom that has lost electrons, thus having a net positive charge. A -ion or anion is an atom that has gained electrons, resulting in a net negative charge.

An atom is considered neutral when it has an equal number of protons and electrons. The protons carry a positive charge and the electrons carry an equal magnitude of negative charge, so when the numbers are equal, their charges cancel each other out, leading to a balanced, or 'neutral', overall charge.

A +ion, or cation, is an atom (or a molecule) that has lost one or more electrons. Since electrons have negative charge, the loss of electrons leads to an excess of positive charge, making the atom or molecule a positive ion.

Conversely, a -ion, or anion, is an atom (or a molecule) that has gained one or more electrons. Since electrons carry negative charge, the gaining of electrons leads to an excess of negative charge, making the atom or molecule a negative ion.

Answer:

Explanation:

Its the straight segment C because its position is not going up or down, so it is not moving.

The motion of an object at rest is represented by a straight line with a slope of zero in a motion graph, likely represented by straight segment C in this case. Curves and lines with slopes indicate motion with either constant or variable speed. Understanding acceleration representation and the concept of reference frames is also critical while interpreting motion graphs.

An object at rest would be represented in a motion graph by a straight line with a slope of zero. This is because the velocity, or speed, of an object at rest remains constant over time, which is zero. In this situation, straight segment C likely represents the motion of an object at rest if it is a horizontal line with no slope. Conversely, curves and lines with slopes indicate motion with either varying or constant velocity.

Additionally, it's important to understand that acceleration (change in velocity over time) can be represented graphically as well. Horizontal lines at some positive or negative value on an acceleration vs. time graph indicate constant acceleration, while variable lines suggest changing acceleration.

Finally, when interpreting such graphs, remember that the concept of reference frames plays a crucial part in understanding motion. As a visual representation, the motion graph describes the motion of an object relative to a defined point of reference. Hence, changing the frame of reference can drastically change the interpretation of the graph.

An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms are made up of smaller particles called subatomic particles, including protons, neutrons, and electrons. Different types of atoms correspond to the different elements on the periodic table.

Among the options you provided, option 'a' most accurately describes an atom: An atom is the smallest particle of an element. Indeed, an atom is the smallest unit of matter that retains all of the chemical properties of its corresponding element. For example, one gold atom retains all of the properties of the element gold.

Atoms themselves are composed of even smaller particles called subatomic particles, including protons, neutrons, and electrons. These subatomic particles contribute to the atom's mass and unique properties. The number of protons and neutrons gives mass to the atom while the number and arrangement of electrons determine the element's properties.

It's also important to note that while all matter is made up of atoms, not all substances are made of the same atoms as suggested by option 'd'. Each type of atom corresponds to a specific element on the periodic table, and these different types of atoms can combine in various ways to form all the diverse substances we see in our universe.

You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid. So, I would say maybe oil.

Do you relizes how many activities lead to global warming? When gas is burned in a car, it produces carbon dioxide (a green house gas). The carbon dioxide then floats up towards the atmosphere and becomes part of the atmosphere. This then causes the heat from the sun to get trapped, bouncing from the atmosphere to the earth. The sun will never stop producing heat which will only lead to the world getting hotter as each decade goes by.  

Hope this helps you!

Many every day activities lead to global warming because they produce pollution. When gas is burned in a car, it produces carbon dioxide, a Greenhouse gas. It floats up towards the atmosphere, and makes holes in the atmosphere which lets in those harmful UV radiation and sometimes also adds more atmosphere which could turn earth into the next venous. This causes the heat from the sun to get trapped, bouncing from the earth to the atmosphere. The sun doesn't stop producing heat, so the world gets hotter, causing many changes in temperature each decade that goes by.

Resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies.

Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies or resonance frequencies. At resonant frequencies, small periodic driving forces have the ability to produce large amplitude oscillations, due to the storage of vibrational energy.

Final answer:

A graduated cylinder is the correct tool for measuring the volume of liquid, with readings taken at the meniscus's lowest point. Pan balances and scales measure mass, not volume, and metric rulers are for measuring length.

Explanation:

The student asked which tool could be used to measure the volume of a liquid. The correct answer is a graduated cylinder. Graduated cylinders are precision instruments commonly used in labs to measure liquid volumes accurately. They can measure in units such as milliliters (mL) and centiliters (cL), offering flexibility for small or large amounts.

To use a graduated cylinder, you should first place it on a level surface and then pour the liquid into the cylinder. Observe the liquid level and make a reading at the bottom of the meniscus, the curve seen at the top of the liquid layer. The meniscus occurs because of the surface tension of the liquid in contact with the container. The correct volume will be where the lowest point on the meniscus aligns with the cylinder's measuring scale.

Other instruments such as a pan balance, scale, and metric ruler are not suitable for measuring liquid volumes. A pan balance and a scale are designed to measure mass, and a metric ruler is typically used for measuring lengths.
