Answer:
About 1.254 moles
Explanation:
The first step is to find the molar mass of selenium. If you take a look at a periodic table, you will find that there is a little number underneath that says something around 78.96 g/mol. Dividing 99 grams by this number, you get about 1.254 moles of Se. Hope this helps!
If the totaling of bromine to cis-cinnamic acid uses the
same mechanism or device as the addition to trans-cinnamic acid, addition of
bromine only transpires on the top (syn) and not the bottommost face (anti). Therefore,
bromine added to cis-cinnamic only adds to the same face (syn addition) as a
result producing only threo dibromides.
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to solve this problem by using the following equation, defined in terms of energy, Planck's constant, wavelength and speed of light:
Thus, we solve for the wavelength as shown below:
And finally plug in the energy, Planck's constant and speed of light to obtain:

The best and most correct answer among the choices provided by your question is the third choice or letter C.
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection plays a role in the water cycle when "<span> gases cycle up and down based on air pressure."
