Answer:
336.8 kilo Joules is the change in internal energy of the system.
Explanation:
The equation for first law of thermodynamics follows:
where,
Q = heat added to the system
ΔU = Change in internal energy
W = work done
We have :
Amount of heat given out by the system will be negatuive as heat relased by the system = Q
Q= 
Work done on the system will positive as work is done on the system:
w = 
336.8 kilo Joules is the change in internal energy of the system.
A substance that
can donate a pair of electrons to form a covalent bond is known as a Lewis
base. It is any substance that can donate a pair of nonbonding electrons. The Lewis
theory suggests that acids react with bases to share a pair of electrons with
no change of oxidation numbers of any atoms.
When magnesium ions and chloride ions form a compound the chemical formula would be MgCl2 which means that for every 1 atom of Mg+ there would be 2 atoms of Cl- bonded. This would be proportional to units of moles.
Moles Cl- = 0.25 mol Mg2+ ( 2 mol Cl - / 1 mol Mg2+) = 0.50 mol Cl- would be needed
Answer:
B
Explanation:
well heterogenous mixtures are not uniformly distributed these meaning whatever components are "mixed" can be seperated easily
a example of this can be
Soil, oil in water, ice in water
while Homogeneous mixture cannot be seen seperated
Hello there!
The correct answer is B. Electrons will be added to an atom starting from the lowest possible level or sublevel.
Hope This Helps You!
Good Luck :)
