Answer:
Explanation:
CH₃Br+NaOH⟶CH₃OH+NaBr
It is a single step bimolecular reaction so order of reaction is 2 , one for CH₃Br and one for NaOH .
rate of reaction = k x [CH₃Br] [ NaOH]
.008 = k x .12 x .12
k = .55555
when concentration of CH₃Br is doubled
rate of reaction = .555555 x [.24] [ .12 ]
= .016 M/s
when concentration of NaOH is halved
rate of reaction = .555555 x [.12] [ .06 ]
= .004 M/s
when concentration of both CH₃Br and Na OH is made 5 times
rate of reaction = .555555 x .6 x .6
= 0.2 M/s
Answer:
we need to know it's
mass and velocity
Explanation:
then use the formula of kinetic energy
Answer:
Wind
Explanation:
Wind turbines make energy by the movement of the natural force on earth called 'wind' and renewable resources are resources that can be made from natural and environment-safe objects or things (e.g. Water, Geothermal Heat, The Sun, and Wind)
As scientists work hard for the results, they may get biased and may sometimes come up with an answer that is based on that. In order to avoid such circumstances, scientific method is put into practice.
Explanation:
- Personal preferences can some times affect a scientific answer. That is not desirable as the experiments will be repeated by different individuals and the same results should be obtained.
- That leads to the importance of documentation of systemic observation, formation of hypothesis and the experimentation to confirm the results, which is the scientific way of coming up with the answer to a scientific problem.
- Scientific methods thus helps in bringing more credibility to findings of the scientists and can be repeated by others to obtain the same results.
Yes and no he said that all atoms of a given element are identical in mass and properties.
