Tricalcium Phosphatea calcium salt of phosphoric acid with the chemical formula Ca3(PO4)2. It is also known as tribasic calcium phosphate and bone phosphate of lime. It is a white solid of low solubility. Most commercial samples of "tricalcium phosphate" are in fact hydroxyapatite.

Acids are defined as compounds that donate a hydrogen ion (H+) to another compound (called a base). Traditionally, an acid (from the Latin acidus or acere meaning sour) was any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0. Correspondingly, a base was any compound that, when dissolved in water, gives a solution with a hydrogen ion activity lower than that of pure water, i.e. a pH higher than 7.0 at standard conditions.
What is structural formula for dichlorine oxide
I Hope this helps, greetings ... Dexteright02! =)
A 50.0 L Of gas with and initial temperature and pressure of 20.0 celius and 2.5 atm is heated to 80.0 celius what is the new pressure inside the bottle at this temperature assume that no gas particle was able to escape out of the battle during the heating.
Convert degree celsius to kelvin when solving gas laws problem.
kelvin = degree celsius + 273.15
Kelvin = 20.0°c + 273.15 = 293.15 K
Kelvin = 80.0°c + 273.15 = 353.15 K
P1 (initital pressure) = 2.5 atm
T1 (initial temperature) = 20.0°c or 293.15 K
P2 (final pressure) = ? unknown
T2 (final temperature) = 80.0°c or 353.15 K
This problem can be solve using Gay-Lussac's Law which state that kelvin temperature is directly proportional pressure when volume and the amount of gas are constant. Formula is P1/T1 = P2/T2.
To Find P2, we can use P2 = P1T2 / T1
P2 = P1T2 / T1
= 2.5 atm × 353.15 K / 293.15 K (cancel unit kelvin)
= 882.875 atm / 293.15
= 3.01 atm
the pressure is 3.01 atm
Hope this helps..=)
