Answer:

A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons

Answer:

Explanation:

When 2 or more elements combine a compound stats to form. These are held together with a very strong chemical bond (which can vary depends on the elements). This chemical bond makes all of these little ions come to it and thats how a chemical reaction is made.

What is the relationship between concentration and rate of reaction?

marshall27 [118]

Explanation:

The answer is directly proportional, because when there is more concentration their will more reactants to react fast diring the chemical reaction which increases the rate of chemical reaction. 

So, we can state that the relationship between them are directly proportional.

The decomposition of ethyl amine, C2H5NH2, occurs according to the reaction: C2H5NH2(g)⟶C2H4(g)+NH3(g) At 85∘C, the rate constan

Answer:

2.772 seconds

Explanation:

Given that;

t1/2 = 0.693/k

Where;

t1/2 = half life of the reaction

k= rate constant

Note that decomposition is a first order reaction since the rate of reaction depends on the concentration of one reactant

t1/2 = 0.693/2.5 x 10-1 s-1

t1/2= 2.772 seconds

How does a scientific theory differ from a scientific law?

Bas_tet [7]

1.A law is an observation; a theory is the explanation of that observation.

2.A theory requires experimentation under various conditions. A law has no such requirements.
3.A theory may become obsolete with time. This is not the case with a law.
4.A theory can be replaced by another better theory; however, this never happens with a law.
5.A theory may be strong or weak according to the amount of evidence available. A law is a universally observable fact.

Hope this helps:)
