Water goes into the sky by condensation I think
According to the Aufbau principle, , electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels (e.g., 1s before 2s).
Get to know first how many moles in the gas:n = pV/RT= (1.013*10^5*750/760) Pa *1.49*10^-3 m^3/(8.314 J/(molK)*298) n = 0.0601 moles.
The combustion energies are 889 kJ/mol (methane) and 2 220 kJ (propane) x = moles methane, y = moles propane
x*889 + y*2220 = 778 x + y = 0.0601----------- x = 0.267784 moles = 0.267784*100/0.0601 = 44.6 % y = 0.243216 moles = 0.243216*100/0.0601 = 55.4 %
Answer:
5.2moles of NaCl
Explanation:
The equation for the reaction is:
2Na + Cl2 —> 2NaCl
From the equation,
2moles of Na produced 2moles of NaCl.
Therefore, 5.2moles of Na will also produce 5.2moles of NaCl
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
