Which event always involves a chemical change A boiling B melting C conducting D burning

Answers

The answer is Burning

Answer:

burning

Explanation:

When a chemical change occurs, the matter is transformed into a new substance. When a substance is burned, it will change into something new. Thus, you know that burning is a chemical change. All the other options are physical properties. The substances may change state, but they will not change identities.

A substance has a density of 3.56 g/mL and a mass of 5668 g. What is the volume?

Answers

Answer:

The answer is

1592.13 mL

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question

mass of substance = 5668 g

Density = 3.56 g/mL

The volume is

[tex]volume = \frac{5668}{3.56} \\ = 1592.1348314[/tex]

We have the final answer as

1592.13 mL

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).

Which statement accurately describes the chemical symbol of an element?

O The chemical symbol is always a single letter.
O The chemical symbol always starts with the same letter as the name of the element.
O The chemical symbol always begins with a capital letter.
OThe chemical symbol can be shared by more than one element.

Answers

Answer:

The chemical symbol always begins with a capital letter.

Explanation:

Answer:

c

Explanation:

The chemical symbol of an element always starts with an chemical letter so here the answer is that the chemical symbol always begins with a capital letter.

It can be seen in the different elements chemical symbol .

For example, Tin is having chemical symbol as Sn while lead is having chemical symbol as Pb.

In both these elements, the chemical symbol starts with a capital letter but none of these have their symbol starts with same letter as their name.

Answer:

True

Density = mass/volume

Suppose that a block has a mass of 20 g and a volume of 20 cm^3.

Density = 20 g/20 cm^3 = 1 g/cm^3

Now, you cut the block in half. The half-block has a mass of 10 g and a volume of 10 cm^3.

The density of the half-block is

Density = 10 g/10 cm^3 = 1 g/cm^3

The density stays the same, even though the size of the sample has changed.

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.

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.
