The mass of a block is 12 grams and the volume is 6 ml. Calculate the density of the

Chemistry
1 answer:
KengaRu [80]2 years ago
3 0

Answer:

The density of block is 2 g/mL.

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

mass of block = 12 g

volume =  6 mL

density = ?

Now we will put the values in the formula,

d= m/v

d = 12 g/ 6 mL

d = 2 g/mL

so, the density of block is 2 g/mL .

What is the particle that is labeled with a question mark (?) in the diagram?
Nat2105 [25]

Answer is: quark.

Quark is a type of elementary particle and a fundamental constituent of matter.

Quarks form composite hadrons (protons and neutrons). Protons and neutrons are in the nucleus of an atom.

Hadrons include baryons (protons and neutrons) and mesons.

There are six types of quarks: up, down, strange, charm, bottom, and top.

Rank the solutions below in order of increasing acidity. (Drag and drop into the appropriate area)
Vladimir79 [104]

Answer:

0.1 M NaOH, 3 M NH3, 0.01 M CH3COOH, 0.01 M H2SO4, 0.1 M HCl

Explanation:

Strong acids are more acids than weak acids. In the same way, strong bases are more basic than weak bases that are in the same concentration.

Then, the more concentrated acid or base will be more acidic or basic.

CH3COOH. Weak acid

NaOH. Strong base

H2SO4. Strong acid

NH3. Weak base.

HCl. Strong acid

The less acid (More basic):

<h3>0.1 M NaOH, 3 M NH3, 0.01 M CH3COOH, 0.01 M H2SO4, 0.1 M HCl</h3>

Strong base, weak base, weak acid, diluted strong acid, undiluted strong acid

7. List things that have LOTS of kinetic energy, and tell why.
vlabodo [156]

Answers: -

For high kinetic energy, the object must have high speed of movement.

1) An airplane has a lot of kinetic energy. Airplanes move at high speed and thus posses a lot of kinetic energy.

2) A bullet from a gun has a lot of kinetic energy due to the high speed of bullet.

3) A formula one car moving at high speeds have a lot of kinetic energy.

4) A train moving at high speed has lots of kinetic energy.

5) An asteroid has a lot of kinetic energy due to it's high speed.

6) A roller coaster moving at high speeds have a lot of kinetic energy.

7) A missile fired from a fighter plane has lots of kinetic energy.

2) Nitrogen gas will react with hydrogen gas to produce ammonia, NH3, How many
Delicious77 [7]

Answer:

12 grams of hydrogen gas

and 56 grams of nitrogen gas

The molar mass of ammonia is 17 g/mol.

68 grams of ammonia corresponds to  

17g/mol

68g

​

=4moles

4 moles of ammonia will be obtained from  

2

4×1

​

=2  moles of nitrogen and  

2

4×3

​

=6  moles of hydrogen.

The molar masses of nitrogen and hydrogen are 28 g/mol and 2 g/mol respectively.

2 moles of nitrogen corresponds to 2×28=56  grams.

6 moles of hydrogen corresponds to 6×2=12  grams.
