Answer:
CH3O- , OH-, NH-2
Explanation:
The given nucleophilic compounds:
Hydroxide, OH-, Ammonia, NH3, Water, H2O, Methanol, CH3OH, Methoxide, CH3O-, Cyanide, CN-, Amide, NH2-
<u>Nucleophile capable for doing E2reaction:
</u>
Generally strong basic compounds are used for E2- Elimination. Because in E2 - elimination proton abstraction and leaving group leaving happen on same time so we need strong base for E2-elimination.
In the given compounds only CH3O- , OH-, NH-2, are strong basic compounds so these compounds only capable for doing E2-Elimination.
Answer:
<u>B. 2</u>
Explanation:
A single bond contains <u>2</u> shared electrons.
Given example is that of <u>ethane</u>
Answer:
1.39 × 10⁴ g
Explanation:
Step 1: Given data
Density of gold (ρ): 19.3 g/cm³
Volume of the gold bar (V): 720 cm³
Step 2: Calculate the mass (m) of the gold bar
The density of a substance is equal to its mass divided by its volume. This is expressed through the following expression.
ρ = m/V
m = ρ × V
m = 19.3 g/cm³ × 720 cm³
m = 1.39 × 10⁴ g
The mass of the gold bar is 1.39 × 10⁴ g.
Answer:
Explanation:
Hello,
In this case, it is firstly necessary to compute the dissolved moles of hydrogen chloride into the water as shown below:
Thus, the molarity is computed as shown below:
Wherein no change in volume is considered, therefore the volume of the solution was the same volume of water.
Best regards.
