It's simple what they're asking for is for you to that each element in the periodic table there is a certain number in their labeling the elements starting them off from 1 to 32 or so. So what it wants you to do is that you start from the top of the table counting down since it says period 5 so period 5 starts at 37 RB so start naming the number of those elements in those following columns just like 37 RB
after that say 38 SR, 39 Y, 40 ZR and so on and so forth
Hope this helps!!
Please mark me as brainiest if I helped you out!!
Answer:
a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.
Explanation:
There are six (6) bonding electrons are in the lewis structure of carbon monoxide (CO).
In Lewis structure, there are ten (10) valence electrons of Carbon monoxide (CO). For lewis structure we need a triple bond between carbon and oxygen, so when electrons made a triple bond it means there is six bonding electrons in lewis structure of carbon monoxide.
it is over 32 degrees Fahrenheit (freezing), and below 120 degrees Fahrenheit (boiling)
So the molar mass of a Hydrogen molecule is 2. If you have 10 grams of Hydrogen molecules, you have 5 moles of Hydrogen molecules (10 moles of Hydrogen atoms). Avogadro's number is 6.0225x10^23. This means that one mole of a substance has that many particles.
