First you need to know the different between an ionic and covalent bond. An ionic bond is the pairing of a metal and non-metal element. A covalent bond is the pairing of 2 nonmetals.

Metals are the elements at the left of the periodic table while non-metals are the elements at the right of the periodic table.

You should also know the diatomic (di means 2) molecules also known as the fab 7. These molecules will always form covalent bonds. These molecules are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. With the subscripts, these molecules would be written as H ₂, N ₂, O ₂, F ₂, Cl ₂, Br ₂, and I ₂.

Marshall determines that a gas has a gauge pressure of 276 kpa what's the absolute pressure of the gas
omeli [17]
A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.

Hypothermic body temperature can range from 28.7 °C to 35.5 °C. What is this range in degrees Fahrenheit?
Amanda [17]
Solution:

To convert Celsius to Fahrenheit, the formula to be used is (C * 9/5) + 32

So in our given, 28.7 degrees Celsius:

Farenheit = (28.7 * 9/5) + 32
= 51.66 + 32
= 83.66 degrees Fahrenheit

Next, 35.5 degrees Celsius:
Farenheit = (35.5 * 9/5) + 32
= 63.9 + 32
= 95.9 degrees Fahrenheit

So in Fahrenheit, the range would be 83.66 – 95.9 degrees Fahrenheit.

Answer:

2.08 L

Explanation:

V_{2}  = V_{1} (\frac{P_{2} }{P_{1} })

= 2.50L × (\frac{1.25 atm}{1.5 atm} )

=2.08L
