How do different types of waves make particles of matter move

1 answer:

6 0

That depends on the wave, if you're talking about sound, it makes matter move in a similar wavelength as them, a mountainous shape. Light however would make whatever matter it hits start to move in the same direction as the light's angle of approach.

A certain chemical reaction releases 27.4 kJ/g of heat for each gram of reactant consumed. How can you calculate what mass of re

Fed [463]

A chemical reaction of exothermic kind releases energy in the form of heat and light.

We are given that reactant releases 27.4kJ/g for every gram of reactant consumed.

We are required to find number of grams of reactant that has been consumed

It is also given that 880J of energy is released

Hence, grams of reactants consumed is 880/27.4gm

Arrange the following compounds in decreasing order of acidity from left to right, and explain the reason in less than 90 words.

saveliy_v [14]

Explanation:

More is the electronegativity of atoms attached to the alpha carbon atom more will be the attraction of electron towards it. As a result, release of hydrogen ion will be easier.

Therefore, there will be increased in acidity of the compound.

Since, fluorine, chlorine and bromine are all group 17 elements and fluorine is more reactive than chlorine. On the other hand, chlorine is more reactive than bromine.

Hence, ability to attract the electrons towards itself will be maximum in fluorine and least in bromine.

Therefore, decreasing order of acidity of the given compounds is as follows.

$CF_{3}COOH$ > $CCl_{3}COOH$ > $CBr_{3}COOH$ > $CH_{3}COOH$
