Answer:
The number of molecules is 3,01E23 of N2
Explanation:
We use the formula PV=nRT, and STP: 1 atm of pressure and 273 K of temperature.
PV=nRT ---> n=PV/RT
n= 1 atm x 11,2 l /0,082 l atm/ Kmol x 273K
n= 0, 5 mol
We use the number of Avogadro:
1 mol---------6, 02E23 molecules
0,5 mol----- x= (0,5 mol x6, 02E23 molecules)/ 1 mol = 3,01E23

A g I need the answer too
Explanation:
Reactants are what is changed in the chemical reaction. They go before the arrow when you wrote the equation. Products are what is formed when the chemical reaction occurs. Products always contain the same elements as the reactants, but they might be rearranged because of the reaction. In this picture, you can see that the reactants go before the arrow, and the products go after.
Answer:
DISADVANTAGES OF ELECTRONIC COMMUNICATION
The cost of development: Electronic communication requires huge investment for infrastructural development. Frequent change in technology also demands further investment. Legal status: Data or information, if faxed, may be distorted and will cause zero value in the eye of law.
