Answer:
B
Explanation:
To calculate questions like this, you need to make use of the equation below:
ν = c / λ
ν is the frequency, c is the speed of light, and λ is the wavelength
ν = c / λ
2.45 • 10^9 Hz = (3•10^8 m/s)/(λ)
λ = 0.122 m = B
PV
= nRT
We
are solving for pressure. We are given the volume, which is 0.100 L (equivalent
to 100 mL). The temperature is 273.15 K (equivalent to 0 Celsius). All we need
to do is convert the grams to moles before we can solve for pressure.
N₂
has a molecular mass of 28.02. This means that 510 g N₂ * (1 mole N₂/28.02 g
N₂) = 18.2 moles N₂
PV
= nRT
P
= nRT/V
R
is the gas constant. R = 0.08206 atm*L/(K*mol)
P
= (18.2 mol)*(0.08206 atm*L/(K*mol))*(273.15 K) / (0.100 L)
<span>P
= 4.08 *10^3 atm</span>

<span>The pressure is 4.08*10^3 atm.</span>
Hey There!
Moles of solution = 7.0 moles
Volume in liters:
569 mL / 1000 => 0.569 L
Therefore:
M = n / V
M = 7.0 / 0.569
= 12.30 M
Hope that helps!
Answer: EPA regulates the production and distribution of commercial and industrial chemicals, in order to ensure that chemicals for sale and use in the United States do not harm human health or the environment.
Explanation:
Answer:
The major and minor products formed from the first structure have more alkyl groups on the C═C than those formed from the second structure
Explanation:
When we consider the structures of the major and minor products from the dehydrohalogenation of structure 1 by E2 mechanism, it is easy to see that the both products are highly substituted by alkyl groups. It is a fact in organic chemistry that the more substituted an alkene is the more stable it is and the more quickly it is formed; Hence the answer
