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
<u>Answer:</u> The final volume will be 14.85 L.
<u>Explanation:</u>
To calculate the final volume when temperature increases, we use Charles' Law.
This law states that volume is directly proportional to the temperature of the gas if number of moles and pressure remains constant.

where,
= Initial volume and temperature
= Final volume and temperature
We are given:

Putting values in above equation, we get:


Hence, the final volume of the gas is 14.85L
Answer:
C
Explanation:
Well movement is, reproduction is, responsiveness is, metabolism is, so accumulation would be the answer.
Answer: Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
(1)Extra greenhouse gases in our atmosphere are the main reason that Earth is getting warmer.
(2)Greenhouse gases, such as carbon dioxide (CO2) and methane, trap the Sun's heat in Earth's atmosphere.
(3)It says that the 1997 Kyoto Protocol was an unmitigated success, with every single one of the 36 countries that signed up reducing their mean annual greenhouse gas emissions from 2008-2012 by an average of 5% relative to the levels seen in 1990.Jun 15, 2016 Many argue that Kyoto's failure is due to deficiencies in the structure of the agreement, such as the exemption of developing countries from reductions requirements, or the lack of an effective emissions trading scheme.by 2012
