An atomic number is <span>the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table or chart.</span>
The only list containing molecules is list #4
NaCl, N2, and H2O are all made up of more than one element, making them molecules. The other lists contain an element. Mg, He, and Fe are elements, not molecules.
Hope this helps!
Answer:
They form Calcium sulphate and water.
Explanation:
H2SO4 + Ca(OH)2 ----> CaSO4 + 2H2O
Acid + Alkali ---> Salt + Water.
Answer:
The electron configuration for the first row transition metals consists of 4s and 3d subshells with an argon (noble gas) core. This only applies to the first row transition metals, adjustments will be necessary when writing the electron configuration for the other rows of transition metals.
Explanation:
Answer:
Q=7200 W
q=7200/72=100 
Explanation:
Given that
ΔT=15° C
Thickness ,t=15 cm
Thermal conductivity ,K=1 W/m.°C
Height,h=6 m
Length ,L=12 m
As we know that heat conduction through wall given as
Now by putting the values
A= 6 x 12 =72 
Q=7200 W
Q is the total heat transfer.
Heat flux q
q=Q/A
q=7200/72=100
q is the heat flux.
As w know that heat flux(q) is the heat transfer rate from per unit area and on the other hand heat transfer(Q) is the total heat transfer from the surface.
Heat flux q=Q/A
That is why these both are different.
