Answer:

[tex]3.2\times 10^{-18}\ C[/tex]

Explanation:

No of electrons, n = 20

We need to find the total charge. We can use quantization of electric charge in this case.

Net charge,

q = ne

e is charge on an electron

[tex]q=20\times 1.6\times 10^{-19}\\\\q=3.2\times 10^{-18}\ C[/tex]

So, there are [tex]3.2\times 10^{-18}\ C[/tex] of charge in 20 electrons.

Answer:

7.20 kg/L

Explanation:

Density is mass (kg) / volume (L).

18.00kg/2.50L = 7.20 kg/L

If you need it in g/mL this is the equation:

[tex]\frac{7.20kg}{L} *\frac{1000g}{1kg} *\frac{1L}{1000mL} = 7.20g/mL[/tex]

Explanation:

Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute

Answer:

λ= 4.99 * 10^-17

Explanation:

C= F * λ

F= frequency(Hz)

λ= wavelength(m)

C= 3.0 * 10^8

F= 6.01 * 10^24

λ= ?

3.0 * 10^8= (6.01 * 10^24) λ

***Simplify

λ= 4.99 * 10^-17

Answer:

Chitin

Explanation:

A fly's main body is made of a thorax and an abdomen. These parts are covered by a hard exoskeleton made of a bony substance called chitin.

The exoskeleton of a housefly is made up of chitin. Thus, the correct option for this question is B.

The Exoskeleton may be defined as a tough and rigid external covering present in some invertebrate animals like arthropods. It supports and protects the animals with respect to their external environment.

The main body of a housefly is significantly divided into two regions, i.e. a thorax and an abdomen. The thorax region is further divided into three parts i.e. prothorax, mesothorax, and metathorax.

All these parts of a housefly are remarkably covered by a tough exoskeleton that is constructed of chitin. The housefly has a hard exoskeleton that protects it from moisture loss.

Therefore, the exoskeleton of a housefly is made up of chitin. Thus, the correct option for this question is B.

Answer:

The larger the difference in electronegativity, the larger the dipole moment.

Explanation:

Answer:

B

Explanation:

to find how many moles we have you need to use the molarity equation which for this is

40g * (1mole/200g) = .2 moles

Given we know that we have .2 moles

then all you have to do is divide amount of moles by amount of liters to find the molarity

for this problem it is

.2mol/2L which is .1 M

The space objects fall to earth because of the gravitational force of the earth. Earth pulls all objects towards itself by gravity.

Every object and person in their respective locations can be attributed to the force of gravity. It lends an object weight. Everyone will be floating in the air if there is no gravity.

Differing locations experience different levels of gravity. Similar to the earth, there is a strong gravitational pull. There is the less gravitational pull on the moon. In mars, there is less gravitation force than on earth.

The gravitational force pulls all objects towards itself, that is why if an object from space falls, it falls towards the earth. The gravitational force is very high on Earth.

Thus, due to gravity on earth, all space objects fall to earth.
