A.
Both blocks can be scratched by a piece of glass.
B.
One block has a greater volume than the other block.
C.
Both blocks sink when placed in water.
D.
One block conducts electricity and the other does not.

Answers

Answer:

The answer is maybe B hope it helps

The substances which are made up of only one kind of particle and have a fixed or constant structure is defined as the pure substance. Here One block has a greater volume than the other block so that the blocks are composed of different substances. The correct option is B.

What is volume?

The amount of space occupied by any three dimensional solid is known as the volume. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. It is simply how much space an object or substance takes up.

It is possible to have the volume without mass, such as an enclosed vacuum. The capacity of a container is not necessarily the same as its volume. It is the interior volume of a vessel. If you measure the exterior dimensions of the container, its volume is greater than its capacity.

Here the blocks are composed of different substances is indicated by the difference in the volume of the blocks.

Thus the correct option is B.

Show your work

Answers

Answer:

2059.645g Cl

Explanation:

A mole of any element contains 6.022e23 molecules, so we will divide the given amount of molecules by 6.022e23.

3.5e25 / 6.022e23 = 5.81e1

5.81e1 = 58.1 mol Cl

Now that we have found the amount of moles of Chlorine, we will multiply the number of moles by the molar mass of Chlorine, which is 35.45g/mol.

35.45(58.1) = 2059.645g Cl

Be sure to check your grammar and spelling.

Answers

Answer:

Static electricity is a type of energy that is produced by friction.

Explanation:

Static electricity may be the result when there is an imbalance between the negative charges and the positive charges in the surroundings. They are non contact forces. They pull of push without actually touching the body. The charged particles interact by pulling or pushing the uncharged particles.

These charges are released when they come closer to some uncharged or other charged particles like the electrostatic charges. It is the charge build up in an area.

A gas sample at 40° C occupies a volume of 3.22 L. If the temperature is raised to 55°C, what will the volume be, assuming the pressure remains constant?

Answers

Answer:

3.374L

Explanation:

According to Charle's Law:

V1/T1=V2/T2 (At constant pressure and moles)

where V=Volume and T=Temperature.

The temperature must be in kelvin.

K=C°+273

T1=40+273=313K

T2=55+273=328K

By applying the formula, we get:

3.22/313=V2/328

V2=(3.22*328)/313

V2=3.374L

What volume of 2.0 M hydrochloric acid solution will be consumed when it reacts with 5 grams of magnesium to form magnesium chloride and hydrogen gas?
2HCl + Mg -> MgCl2 + H2

Answers

Answer:

Explanation:

Remember, matter can neither be created nor destroyed, so every atom of reactant the leftt side of the equation must be accounted for in the products on the right side of the equation. With magnesium and hydrochloric acid we have: Mg + 2HCl → MgCl2 + H2(g). Magnesium is divalent, and so requires two chloride ions to form magnesium chloride. Hydrogen gas is a diatomic molecule, so the reaction requires the product to be H2. Going across the equation from left to right we have 1 atom of magnesium (accounted for on the right side of the equation), and on the left, 2 moles of hydrochloric acid; the two hydrogens represented on the left of the equation are accounted for on the right of the equation. Likewise, the two chloride anions on the left of the equation are accounted for in the formation of MgCl2 on the right. When all the atoms are accounted for on both sides of the equation, we say the equation is "balanced".

I need help I don’t really get what I have to do to get the answer

Answers

Reactants are what you start with. Products are what come into being by or through the reactants. You can figure out what the products are in these sentences (which are really chemical equations written out in words rather than symbols) by looking for terms like “yield(s)/to yield,” “form(s)/to form,” “produce(s)/to produce,” “give(s)/to give,” etc. All of these terms provide the notion that you’re getting or making something. The specific substance(s) that follow these terms would be your product(s); the substance(s) that precede these terms would be your reactant(s).

So, for question 2, we see the term “produces.” There is one substance that precedes that term—potassium chlorate, which would be our sole reactant. And there are two substances that follow that term—potassium chloride and oxygen gas, which would be our two products.

In question 3, we see the term “yields” preceded by ammonium nitrate—our sole reactant—and followed by nitrogen gas, oxygen gas, and water vapor—our three products.

Lastly, in question 4, we see the explicit term “produces.” Moreover, we are told directly that dinitrogen tetrahydride reacts with oxygen gas; it should be pretty clear that these two substances are our two reactants here. The substances that we are told are produced are nitrogen gas and water, which would be our two products.

Which is a characteristic of a physical change?

a
The chemical bonds in the substance are unchanged.

b
The change cannot be seen.

c
The molecules all move at the same speed.

d
The substance has reacted with another substance.
