Compare photons and electrons. which of the following statements is true?

Photons are units or packets of electromagnetic energy. They carry no charge or mass.

While, electrons are constituents of an atom that are negatively charged and associated with a certain mass. In fact, electrons in an atom can get excited when they absorb photons of characteristic energy from electromagnetic radiation.

The similarity between photons and electrons is that both can behave as particles as well as waves.

Ans B

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

your answers are a,b,,e and f

i hope this
