For parallel resistors:
equivalent resistance: 85.7 ohms
for total circuit:
85.7 + 220 = 305.7ohms

Hello there!
Electronegativity is the atom's tendency to attract electrons in a chemical bond
There are two trends to electronegativity:
- Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example)
- Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)
Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.
- Sn belongs to group 4A (group 14)
- Sb belongs to group 5A (group 15)
- Te belongs to group 6A (group 16)
- I belongs to group 7A (group 17)
As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity
Hope this helps!
Answer:
Partial pressure of Ar = 4.7 atm
Explanation:
Total pressure of a mixture of gases = Sum of partial pressure of each gas
This mixture contains: O₂, He and Ar.
Total pressure = 15.3 atm
Total pressure = Partial pressure O₂ + Partial pressure of He + Partial pressure of Ar
15.3 atm = 7.4 atm + 3.2 atm + Partial pressure of Ar
Partial pressure of Ar = 15.3 atm - 7.4 atm - 3.2 atm
Partial pressure of Ar = 4.7 atm
Explanation:
Except for the use in the chemistry laboratory , were it is used to synthesize many useful products, silver nitrate is also has biolofical and medical relevance.
Silver nitrate is commonly used for silver staining, for demonstrating the reticular fibers, the proteins and the nucleic acids. It is also used as stain in the scanning electron microscopy.
Silver Nitrate is also used for the bone ulcers as well as the burns and the acute wounds.
