Explanation:
In general, to balance an equation, here are the things we need to do:
Count the atoms of each element in the reactants and the products.
Use coefficients; place them in front of the compounds as needed.
Answer:Discuss experiments that led to discovery of the electron and the nucleus ... These particles had a similar mass as protons, but did not have the same ... The atomic nucleus contains a mix of positively charged protons and ... Intro to the History of Atomic Theory – Intro: Rutherford, Thomson, electrons, nuclei, and plums.
Explanation:
When n=2 we have 8electrons, when n=4 l=1 we have 6electrons, when n=6 l=2 m-l=-1 qe have 1electron
Colligative
properties calculations are used for this type of problem. Calculations are as
follows:<span>
ΔT(freezing point) = (Kf)m
ΔT(freezing point)
= 1.86 °C kg / mol (0.50 mol/kg)
ΔT(freezing point) = 0.93 °C
Tf - T = 0.93 °C
<span>T = -0.93 °C</span></span>
The answer would be:
D = M/V
D=Density
M= mass
V= volume
