Which is something that a PURE SUBSTANCE and a SOLUTION have in common?A) They both are made of one kind of particle.
B) They both are made of different kinds of particles.
C) They both look speckled or chunky.
D) They both look uniform (the same) throughout.

Answers

Answer 1
Answer:

D) They both look uniform (the same) throughout.

Further explanation

Pure substance can be any element or compound and is formed from one type of atom/molecule only

Meanwhile, the solution is included in a mixture consisting of 2 or more pure substance

Pure substance can be formed through a chemical process while the mixture is through a physical process

Mixture can be separated by physical processes into components of pure substance while pure substance cannot

The mixture itself consists of a homogeneous and heterogeneous solution

The mixture can be divided into a homogeneous mixture if the composition/ratio of each substance in the mixture is the same and a heterogeneous mixture if the ratio of the composition of the substances is not the same (can be varied) in each place.

Mixtures can also be divided into solutions, suspensions, and colloids based mainly on the size of the particles

Homogeneous mixture = Solution

Heterogeneous mixture = suspension, and

The mixture is located between suspension and solution = Colloid

At normal temperature and pressure, air has a density of 0.001184 g/mL. What is the mass of air in a room that is 3.07 m by 3.00 m by 3.77 m? Answer in units of kg.

Answers

1 ml = 1 cm3
The volume of the room is 34.7217 m3 or 34.721.700 cm3, so 34.721.700 * 0.001184 g/cm3= 41,1104928 kg.

Which statement best compares the energy involved in melting with the energy involved in boiling for a given liquid?A....Energy is removed from the particles in each change, but more energy is removed in melting than in boiling because the attractions are weaker.

B....Energy is removed from the particles in each change, but more energy is removed in boiling than in melting because the attractions are weaker.

C....Energy is added to the particles in each change, but boiling requires more energy than melting because the attractions must be completely overcome.

D....Energy is added to the particles in each change, but melting requires more energy than boiling because the attractions must be completely overcome.

Answers

The correct answer is C.  When a solid turns into a liquid the intermolecular forces are just weakens enough to allow the molecules to move around each other.  When a liquid turns into a gas the intermolecular forces need to be completely broken since gases ideally do not have any attraction between its particles.  It takes a lot more energy to completely brake intermolecular attractions than it does to weaken them.  
I hope this helps.  Let me know if anything is unclear.

C. Energy is added to the particles in each change, but boiling requires more energy than melting because the attractions must be completely overcome.

A(n) _____ reaction is a self-sustaining series of chemical reactions in which the product of one reaction are the reactsnts in the next reaction.* not a multiple choice *

Answers

Answer : The answer is, Chain reaction.

Explanation :

Chain reaction : It is defined as the series of successive elementary processes in which the active intermediate species are consumed and regenerated before the products are obtained.

It is a self-sustaining series of the chemical reactions where the product obtained from one reaction are the reactants in the next reaction and so on.

Hence, a chain reaction is a self-sustaining series of chemical reactions in which the product of one reaction are the reactants in the next reaction.
it is called a Chain reaction
