Answer:
667.105ml
Explanation:
V1VP1 / V2P2
V2=V1P1 / P2
Pressure at S.T.P is 760
V2= 600×845/760
V2=667.105ml
Therefore V2 = 667.105ml approximately
Hello!
<span>In the celebrated equation e = mc2, the c2 is the </span>proportionality constant of energy and mass.
This famous equation was proposed by Albert Einstein in 1905, and implies that when there is a certain mass, there is a certain amount of Energy associated with it even is the mass is in a steady state. The proportionality constant c² is the speed of light squared.
Have a nice day!
Answer: a. atominc number= protons= 33
neutrons= mass- atominc number
80-33= 47 neutrons
b.35 protons
46 neutrons
hope this helps
Nitrates and chlorides are highly soluble, whereas sulfates and phosphates are less soluble along with the common ions used in medicine.
<u>Explanation:</u>
Mostly calcium and magnesium salts are utilized in medications. On the basis of the solubility rules, chlorides and nitrates are highly soluble also have few precipitates among the metal salts.
But, sulfates produces a lower solubility salt with calcium, generally in many medications.Additionally phosphate forms the low solubility salts along with Magnesium and calcium that are used in medications.
