Looking at the equation .look at the moles noted below
- Ca(OH)_2=1mol
- NH_2Cl=2mol.
- CaCL_2=1mol
- NH_2=2mol
- H_20=2mol.
#a
There is 2 moles of NH2Cl.
- Hence limiting reagent is Ca(OH)_2
#2
Moles at reactant=3
Moles at product=5
Moles left:-
#d
Fe^2+ makes Mg go from 0 to 2+, Fe^2+ is the oxidizing, Mg makes Fe^2+ go from 2+ to 0, Mg is the reducing.
Fe^2+ is a chemical symbol for ferrous in chemistry. Ferrous refers to iron with oxidation number of +2, denoted iron(II) or Fe2+.
Mg is a chemical symbol for Magnesium in chemistry.
The answer is B. the occurrence of huge events in Earth's natural history
The geologic time scale is a system of chronological dating that relates geological strata to time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history.
Soft light (answer) is the filament between (2700k-3000k).
The higher the kelvin number the whiter the light.
3500k-4100k is bright white/cool white
5000k-6500k is daylight
\and those are the three primary colors of color temperature
