which type of matter cannot be broken done into simplier substances by a chemical change

Answers

Answer: Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P 4) or sulfur (S 8) cannot be broken down into simpler substances by these reactions. Example: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid

What is an intermolecular force?
O A. A force within a covalently bonded molecule
B. A force acting between the atoms within a molecule
O c. A force that holds a molecule together
O D. A force acting between two different molecules

Answers

Intermolecular force is the force acting between two different molecules. There are various kinds of intermolecular forces and the they differ in their strength.

What are intermolecular forces?

Intermolecular forces are force of attraction or repulsion acting between two different molecules in a compound. The like charges of molecules repels and unlike charges will attracts together.

There are different kinds of intermolecular forces such as hydrogen bonding, Van der Waal's forces, dipole, dipole forces, London dispersion forces etc.

The strength of these forces vary from each other. The intermolecular force of attraction holds tow molecules together in a compound. Hence, option D is correct.

A sample of gas has a volume of 526 mL at 346 mmHg and 35.0°C. Determine the moles of gas.​

Answers

Answer:

The moles of gas is 0.009474 moles.

Explanation:

Given that,

Volume = 526 mL

Pressure = 346 mmHg

Temperature = 35.0°C

We need to calculate the moles of gas

Using formula of ideal gas

[tex]n=\dfrac{PV}{RT}[/tex]

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

[tex]n=\dfrac{\dfrac{346}{760}\times0.526}{0.08206\times(35+273)}[/tex]

[tex]n=0.009474\ moles[/tex]

Hence, The moles of gas is 0.009474 moles.

Explanation:

An element has a uniform composition, cannot be broken down by chemical change, every atom has the same atomic number, and can be found on the Periodic Table.

Water is made of hydrogen and oxygen atoms (H₂O) so it is not an element.

Table salt is made of sodium and chloride atoms (NaCl) so it is not an element.

Iron oxide is made up of iron and oxygen atoms, so it is not an element.

Hydrogen is an element. It can be found on the Periodic Table as element H.

2. If a person in a wheelchair wanted to get to the second story of a two-story building, would it be easier to
take a short, steep ramp or a long, shallow ramp? Explain.

Answers

Answer:

The short steep ramp would be much harder because you will have to work more against gravity.

Explanation:

The long shallow ramp would be easier to take than the short, steep ramp because the person would have to use more force on the short, steep ramp to push the wheelchair against the force of gravity.

What is an inclined plane?

An inclined plane or a ramp can be defined as a flat supporting surface tilted at an angle, with one end higher than the other, utilized as an aid for raising or lowering a load.

The inclined plane can be defined as one of the six classical simple machines developed by Renaissance scientists. Inclined planes can be utilized to move heavy loads over vertical obstacles.

Moving a body up an inclined plane needs less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage, the factor by which the force is decreased, is equal to the ratio of the sloped surface's length to the height it spans.

The inclined plane provides the same amount of work to be done with a smaller force exerted over a greater distance. The angle of friction or the angle of repose can be defined as the maximum angle at which a load can rest motionless on an inclined plane because of the friction without sliding down.

A boy found a solid metal box in his backyard. The box had been buried for so long, it was difficult to determine from what the box was made. The boy measured the box and found its volume (v) to be 17.63 cubic centimeters (cm3) and its mass (m) to be 158 grams (g). The boy knows the formula for density (D) is D = m/v. This table shows the density of several metals. DENSITY OF METALS *

A. copper
B. gold
C. silver
D. tin​

Answers

Answer:

Box is made up of copper, because density is 8.96  g/cm³.

Explanation:

Given data:

Volume of box = 17.63 cm³

Mass of box = 158 g

Which metal box is this = ?

Solution:

First we will calculate the density of box then we will compare it with the density value of given metals.

d = m/v

d = 158 g/ 17.63 cm³

d = 8.96  g/cm³

The calculated density is similar to the given density value of copper thus box is made up of copper.

What mass of benzene takes
up
325 mL if its density is
0.874 g/mL?

Answers

Answer:

The answer is 284.05 g

Explanation:

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

mass = Density × volume

From the question

volume = 325 mL

density = 0.874 g/mL

We have

mass = 325 × 0.874

We have the final answer as

284.05 g
