does water in a glass have mass

Answers

Answer 1

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 2

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.

SO YES WATER IN A GLASS HAS MASS :)

Is copper penny react
reaction with Nitric
acid a
Chemical or physical
Change?

Answers

Answer:

The reaction that occurs is a redox reaction. The Copper metal (Cu 0)on the copper pennies is oxidized in concentrated nitric acid to produce Cu2+ ions. Copper is easily oxidized to Cu2+, which is blue in aqueous solutions (water) so you should see the solution turn blue as the copper penny reacts.

Have a nice day ;)(^-^)

Taking into account the definition of chemical and physical change, the reaction of the copper penny with nitric acid is a chemical change.

Physical change

Physical changes are those in which the substances involved are the same before and after the change. That is, a physical change is a transformation in which the nature of matter does not change.

Chemical change

Chemical changes are considered to be those in which the substances involved are transformed into totally different ones.

In this way, the initial substances do not exist after the phenomenon has occurred and instead, new substances are formed, different from the initial ones.

That is, a chemical change is a transformation in which the nature of matter varies.

This case

When a penny of copper reacts with nitric acid, a redox reaction occurs where the copper metal in the copper pennies is oxidized to produce Cu²⁺ ions, whereas because the nitric acid oxidizes the copper, the nitric acid itself is reduced to nitric oxide (NO). Nitric oxide then reacts with oxygen in the air to produce nitrogen dioxide (NO₂). This can be represented by:

Cu + 4 HNO₃ → Cu²⁺(ac) + 2 NO₃⁻  + 2 NO₂ + 2 H₂O

Finally,  the reaction of the copper penny with nitric acid is a chemical change because a redox reaction occurs.

Explain how electron microscopes work and why some scientists might prefer to use electron microscopes instead of light microscopes.

Answers

Answer:

Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

Zinc reacts with hydrochloric acid according to the reaction equation Zn(s)+2HCl(aq)⟶ZnCl2(aq)+H2(g) How many milliliters of 6.50 M HCl(aq) are required to react with 8.75 g Zn(s)?

Answers

Answer:

41.17

Explanation:

n Zn =  mass / m.wt

      = 8.75 /(65.4) = 0.1338 mole

n HCL = ( from the balanced equation )

     2HCL                  Zn

          2mole   → 1  mole

          x  mole     →             0.1338mole

     n HCL = .268 mole

M= mole/liter

6.50= 0.268/x

so u have0.04117  liter = 41.17 ml

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 41.17 ml of 6.50 M HCl(aq) are required to react with 8.75 g Zn(s).

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

number of moles of zinc=  mass / molecular mass

                                       = 8.75 /(65.4) = 0.1338 mole

number of moles of HCl ( from the balanced equation )

2 moles of HCl reacts with one mole of Zn

number of moles of HCl = 2×0.1338 =0.268 mole

Molarity = number of mole of HCl/volume occupied by solution

6.50= 0.268/volume

Volume of HCl = 41.17 ml

Therefore, 41.17 ml of 6.50 M HCl(aq) are required to react with 8.75 g Zn(s).

When paper turns yellow-brown upon exposure to sunlight, what type of change is likely taking place?

a. a physical change
b. a chemical change
c. neither a physical change nor a chemical change
d. both a physical change and a chemical change

Answers

Explanation:

(a) The mass of an object remains the same always. It is independent of its location. In this case, an iron nail is ground into powder. It means that its mass will remain unchanged. Hence, (a) is the correct option.

(b) Whenever there is a change of color of an object, a chemical reaction occurs. It shows that a reaction happens there. In this problem, a paper turns yellow-brown upon exposure to sunlight. A chemical reaction takes place there. Hence, (b) is the correct option.

1) The mass of any substance remains the same irrespective of the state.

Thus, an iron nail ground into powder should have the same mass unless parts of it got lost during grinding.

2) A paper that turns yellow-brown upon exposure to sunlight is likely undergoing a chemical change. It could be that the light oxidizes the atoms of the paper.

Chemical changes occur when the atoms of a substance combine with another substance to form new products. New products are not formed in physical changes and the original product can be retrieved by physical means.
