Bromate anion I hope this helps.
To write the electron configuration, you begin with the
normal electron configuration of the element and then add or deduct the number
of electrons that the charge designates. Rubidium will change from
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1
to
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 because it loses the last
electron.
Ba(OH)2 Ba-2 power + 2 OH H2 + SO 4
All numbers are exponents.
Answer:
Explanation:
Glucose reacts with oxygen do produce carbon dioxide and water:
Given a daily mass of glucose:
Find moles of glucose:
From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:
Convert this into mass using the molar mass of carbon dioxide:
This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:
Hello!
To calculate the
household concentration of NaOH we need to use the
dilution formula, clearing for M2, as you can see in the equation below:
Now, we input the values from the data we have onto this equation. M1=19,1 M; V1=10 mL; V2=400 mL, and solve the equation to get the result:
So, the
household concentration of NaOH will be 0,48 M
Have a nice day!
