Answer:
D= 5 g/L
Explanation:
M= D x Vm
M is the molar mass = 112g/mol
D is the density
Vm is the molar volume whuch is 22.4L at STP
now substitute;
112 = D x 22.4
D= 112\22.4
D= 5 g/L

Answer:
= 155 ppm
Explanation:
PPM also refers to parts per million, it represents a low concentration of a solution. It represents 0.001 gram or a milligram in a 1000 mL, equivalent to 1 mg per liter
Given that;
101 mg of Ca in 650.0 g of water
1 ppm = 1 mg/L
650 g = 650 mL = 0.65 L
Therefore;
= 101 mg/ 0.65 L
= 155.38 mg/L
<u>= 155 ppm</u>
Answer:
TRUE
Explanation:
Glass spun into fine fibers is called fiberglass and is commonly used as an insulator.
Answer:
The transition with the greatest distance is 5p → 1s, which is n = 5 going to n = 1. This means this transition also has the largest energy and frequency. Therefore, the electron transition that produces light of the highest frequency in the hydrogen atom is a. 5p → 1s.
Explanation:
The energy requirement order for excitation for different transitions is as follows. n→∏* transition requires lowest energy while σ→σ* requires highest amount of energy
