Answer:
a) 128 grams
b) 81.25%
Explanation:
a) The mixture will be between the alloy and the pure copper, so the mass will be the sum of the mass of the compounds:
m = 50 + 78 = 128 g
b) In the alloy, 52% is copper, so to know the mass of copper in the alloy, we must multiply the total mass by 52% (which is 0.52)
0.52x50 = 26 g of copper
The total mass of copper in the mixture is 26 + 78 = 104 g
So, the percentual of copper is the mass of copper divided by the total mass
104/128 = 0.8125
Multiplying by 100%, to have the result in percentage
0.8125x100% = 81.25%
Answer:
Model
Explanation:
A model of anything is something you make to represent it in it's physical world form
Answer:
12
Explanation:
pOH = -log(1.0 x 10^-2) = 2
pH = 14 - pOH
pH = 14 - 2 = 12
Compound B will be propene as a result of an elimination reaction involving potassium tert-butoxide and an alkyl halide. In proton NMR, alkenes exhibit signals in the 5–6 ppm range.
<h3>What are Elimination Reactions?</h3>
Elimination reactions are one sort of reaction that are mostly utilized to convert saturated compounds (organic molecules that contain single carbon-carbon bonds) to unsaturated compounds (compounds that feature double or triple carbon-carbon bonds). Additionally, it plays a significant role in the production of alkenes.
The elimination response is composed of the following three major events:
- Proton exclusion.
- The synthesis of a C-C pi bond.
- As a result, the relationship between the departing group's members has grown increasingly distant.
