Answers

Solid have the unique shape and low temperature, plasma have not unique shape and high velocity and both show electrical conductivity.

What is state of matter?

Matter is divided into 4 states as solid, liquid, gas and plasma according to the arrangement of atoms present in that.

Solid state

In the solid state all particles are connected rigidly with each other, and show very less movement that's why maintain a unique structure. They have low temperature as it helps to maintain the rigidity and it also conducts electricity because of the presence of electrons in the constitute atoms.

Plasma state

This is the 4th state of matter in which positively and negatively charged particles are present, these particles are held together by the weak force that's why they show good velocity, and do not maintain a unique shape. Plasma also shows the electric conductivity.

Hence, both state will conduct electricity and show different characteristics.

I NEED HELP!! (mostly w/ torr and atm part)

Answers

Answer:

V2 = 1.14

Explanation:

V1 = 1.2L

P1 = 720 torr (÷ by 760 to get atm. Because 1 atm equal 760 torr) = 0.95 atm

P2 = 1 atm

V2 =?

Follow the equation below to solve this question

P1V1 = P2V2

0.95 x 1.2 = 1 x V2

Answers

0.2 M each of nitric acid and carbonic acid will have the same pH.

pH

The pH of substances is mathematically given as:

pH - -log [H+]

Nitric and carbonic acid dissociates according to the following:

HNO3 ---------> H+ + NO3-

H2CO3 -------> H+ + HCO3-

Thus, both acids ionizes to produce the same number of moles of H+, thus, producing the same pH

A Grignard synthesis begins with 6.00 g of bromobenzene and ends with 3.94 g benzoic acid. What is the percent yield of the benzoic acid

Answers

The percentage yield of the benzoic acid is mathematically given as
P= 84.56 %

What is the percentage yield of the benzoic acid?

Question Parameters:

A Grignard synthesis begins with 6.00 g

and ends with 3.94 g benzoic acid.

Generally, if 157 g of bromobenzene produced = 122 g of benzoic acid

Hence,6 g of bromobenzene will produce

X== (122 / 157 ) * 6

X= 4.66 g

Since the experimental yield of benzoic acid = 3.94 g

Therefore the Percentage yield

P = 3.94 / 4.66  * 100

P= 84.56 %
