Chemistry
1 answer:
laiz [17]2 years ago
4 0

Answer:

three

Explanation:

Every element in the boron group has three electrons in its outermost shell (so-called valence electrons), and for each element there is a sharp jump in the amount of energy required to remove the fourth electron, reflecting the fact that this electron must be removed from an inner shell.

Balance the following H2 SO4 + NaOH ==== NaSO + H2O​
katrin [286]

Answer:

H2SO4 + 2NaOH --->   Na2SO4 + 2H2O

Explanation:

H2SO4 + NaOH --->   Na2SO4 + H2O

                Na1    --->     2Na

H2SO4 + 2NaOH --->   Na2SO4 + H2O

2H   +   2H =  4H       ---->                 2H

H2SO4 + 2NaOH --->   Na2SO4 + 2H2O

     4O  + 2O         ----->          4O   +     2O

What is the mass in grams of 0.375 mol if the element potassium, k?<br><br>​
alexandr402 [8]

Answer: 14.625g

Explanation:

No of moles= mass given/molar mass

No of moles given= 0.375mol

Mass is the unknown (?)

Molar mass of K= 39

No of moles = mass given/molar mass

Substitute the values

0.375= mass/39

Cross multiply

Mass = 39×0.375

Mass= 14.625g

The mass is 14.625g
