The last set which is n=4 l=3 m=3 is a valid set
Answer:
Density should be 8.5
Explanation:
When you subtract 17.2-10.0 for water displacement you get 7.2 which is the volume and you divide it by 15.7 so your equation will be 15.7/7.2 = 8.5
Answer:
An atomic number
Explanation:
If a neutral atom has 30 protons and 34 neutrons, the number of electrons in the atom is: A) 94. B) 34. 64. ... 17) What is the symbol for the ion with 19 protons and 18 electrons? A) F+. B) K+ ... 21) Identify the metalloid in the following list. Hope this helps you! Ask me anything if you have any quistions!
Barium :
with +2 being the charge
Oxygen :
with -2 being the charge
The given equation can be written as:
Ba + O = BaO
Since the sum charges of Barium and Oxygen equals 0, there is no need to add subscripts.
Both Ba and O appear on the left and right side of the equation once, so there is no need to add a coefficient.
Ba + O = BaO is balanced
The
balanced chemical reaction is:<span>
N2 + 3H2 = 2NH3
<span>We are given the amount of the product to be
produced. This will be the starting point of our calculations.
17 mol NH3 ( 1 mol N2 / 2 mol NH3 ) = 8.5 mol N2
Therefore, the required N2 to produce the given amount of ammonia is 8.5 mol.</span></span>
