1.) protons neutrons and electrons
2.) a wall outlet it is made up of metal that conducts heat. When when heat is applied it provides enough energy to these electrons
3.) is an imbalance if electric charges within or on the surface of a material
4.) static electricity decoded tiny changes in the surface of a balloon causes it to charge more when rubbed against our hair
5.) you might have to answer that on your own but if you don’t want to here’s my experience
One day me and my twin brother were jumping on the trampoline and when we fell down my hair rubbed against the surface of it and stuck up
Hope that helped and Brainiest?
There would be 79 electrons present in each atom of gold. I hope this helps :)
Answer:
6.05g
Explanation:
The reaction is given as;
Ethane + oxygen --> Carbon dioxide + water
2C2H6 + 7O2 --> 4CO2 + 6H2O
From the reaction above;
2 mol of ethane reacts with 7 mol of oxygen.
To proceed, we have to obtain the limiting reagent,
2,71g of ethane;
Number of moles = Mass / molar mass = 2.71 / 30 = 0.0903 mol
3.8g of oxygen;
Number of moles = Mass / molar mass = 3.8 / 16 = 0.2375 mol
If 0.0903 moles of ethane was used, it would require;
2 = 7
0.0903 = x
x = 0.31605 mol of oxygen needed
This means that oxygen is our limiting reagent.
From the reaction,
7 mol of oxygen yields 4 mol of carbon dioxide
0.2375 yields x?
7 = 4
0.2375 = x
x = 0.1357
Mass = Number of moles * Molar mass = 0.1357 * 44 = 6.05g
