B. providing a moderate, livable climate. The atmosphere basically means the canopy that shields us. If it isnt moderate or doesnt have livable climate, I dont think we would be able to survive. :|
Answer : The new volume of will be, 5600 mL
Explanation :
To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.
The equation follows:
where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
Now put all the given values in above equation, we get:
Therefore, the new volume of will be, 5600 mL
Answer:
It leads to new jobs that search for innovative ways to control emissions.
Explanation:
Publishing a report that is a revised list of green house gases by scientists underscores the importance of new new jobs that seek ways of controlling emissions. The publication will inspire scientific research into control of emission of greenhouse gases. This will create new jobs for scientists who will be charged with the responsibility of ensuring that emission of Tue newly discovered greenhouse gasses is greatly reduced.
Several scientists earn a living by actively carrying out research on control of the emission of greenhouse gasses.
Answer:
0.112 M.
Explanation:
- Molarity is the no. of moles of solute in a 1.0 L of the solution.
M = n/V.
<em>M = (mass/molar mass)solute x (1000/V of the solution).</em>
mass = 127.62 g.
molar mass = 286.138 g/mol.
V of the solution = 4.0 L = 4000.0 mL.
<em>∴ M = (mass/molar mass)solute x (1000/V of the solution)</em> = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = <em>0.1115 M ≅ 0.112 M.</em>
