Using the balanced equation N2+O2=2NO, how many grams of NO can be produced when 25.0 grams of N react?
Oxana [17]

Answer:

53.55gNO

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is possible for us to calculate the produced grams of nitrogen monoxide by starting with 25.0 g of nitrogen via their 1:2 mole ratio and the molar masses of 30.1 g/mol and 28.02 g/mol, respectively and by some stoichiometry:

=25.0gN_2*\frac{1molN_2}{28.02gN_2}*\frac{2molNO}{1molN_2}*\frac{30.01 gNO}{1molNO}\\\\=53.55gNO

Best regards!

Explain how an atom is composed of charged particles yet can have an overall charge of zero.
Marina CMI [18]
Atoms have an overall charge of zero because the charge of the electron is canceled by a proton and a neutron has a net charge of 0.If you were to take out an electron,you will create an ion(ion is an atom with a charge).This ion will have a charge because it now has different amount of electrons and protons.
