Answer: Silicon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Silicon go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.
Hope this helps! :)
Answer:
C. The hand shears because their shorter handles transfer force more quickly to the cutting blade.
Explanation:
Answer:
The molarity of the solution is: 2 M
Explanation:
We calculate the weight of 1 mol of NaOH:
Weight 1 mol NaOH= Weight Na + Weight 0 + Weight H= 23 g+16g+ 1 g= 40g/mol
The molarity is the quantity of moles in 1000ml (1 liter) of solution:
0,5liter-----40 grams NaOH
1 liter----x=(1 liter x 40 grams NOH)/0,5 liter = 80 grams NaOH
40 grams----1 mol NaOH
80 grams----X=(80 grams x 1 mol NaOH)/40 grams= 2 mol NaOH--> 2M
