Answer:
4m/s^2
Explanation:
Acc. = final velocity - initial velocity / time taken
= 50 - 10 / 10
= 40/10 = 4ms^2
Answer:
Final temperature = 149 K
Explanation:
Given data:
Initial temperature = 25°C (25+273 = 298 K)
Initial volume = 4.5 L
Final temperature = ?
Final volume = 9.0 L
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₂ = T₁V₂/V₁
T₂ = 4.5 L × 298 K / 9.0 L
T₂ = 1341 L K / 9.0L
T₂ = 149 K
Answer:
The 2 different combinations are given in the attached figure. The 2nd combination has a higher yield due to less hindrance by the alkyl halide.
Explanation:
The first reaction is between an alkyl halide and metal alkoxide. In this case, the alkyl chloride would be a secondary component and thus will cause greater hindrance to the yield. The reaction is as given in the attached figure
The second reaction is between a benzene ring containing halide and metal alkoxide. Now as the reaction is via alkyl chloride being the primary agent, there is less hindrance and thus greater yield in this case.
