Answer:
0.13 atm
Explanation:
Using the Ideal Gas Law; PV=nRT, we can rearrange to solve for pressure.
P=nRT/V
P is pressure, n is number of moles (0.023), R is a constant (0.08206 L*atm/mol*K), T is temperature in Kelvin (293.15K) and V is volume, 4.2 L.
So, plugging in;
P=(0.023mol)(0.08206L*atm/mol*K)(293.15K)/(4.2 L)
P=0.1317 atm
P=0.13 atm; multiply by 760 to get to Torr or mmHg.
C. rate = k[C4H9Br]
The slow step is always the rate-determining step. In the slow step, C4H9Br is the only reactant and has a coefficient of 1, so it is first order in the rate law.
Answer:
The longer the path length, the more molecules there are in the path of the beam of radiation, therefore the absorbance goes up. As you likely know from other experiences, a particular chemical species absorbs some wavelengths of radiation and not others
The movement of the blades represents wind energy.
The visible light that allows people to see where they are going describes light energy.
<h3 /><h3>What is a wind energy?</h3>
A wind energy is the energy that results from the blowing the wind.
The blowing of the wind causes the windmill blade to rotate converting kinetic energy into mechanical energy of the moving blades.
<h3>What is light energy?</h3>
Light energy is the energy that allows light to be visible to human eyes.
Thus, we can conclude that the movement of the blades represents wind energy.
The visible light that allows people to see where they are going describes light energy.

The correct answer is false. Not only one type of balance is present in a laboratory. Most laboratory I've worked into owns two types of balance namely the analytical balance and the top-loading balance. The former is used for accurate mass readings and those needs smaller amounts of a substance while the latter is used for approximation and large amounts of substances.
