Answer:

Explanation: was given the equation: Ca(OH)2 + H3PO4 --> H2O + Ca3(PO)4, which I balanced to:

3 Ca(OH)2 + 2 H3PO4 --> 6 H2O + Ca3(PO)4

I am supposed to find

a) How many grams of calcium phosphate are produced from the reaction of 25.0g of Ca(OH)2 with excess H3PO4.

b) If 0.139 moles of Ca(OH)2 react with 0.58 moles H3PO4, determine the grams of H2O produced and the grams of the excess reagent left after the reaction.

Why can scratching at the bottom of a flask induce crystallization?
Ksenya-84 [330]

Scratching causes cracks and crevices on the surface of the flask (though microscopically). These will act as favorable sites for nucleation, which leads to the formation of crystals.

Answer:

Temp decreased

Explanation:

If the container is sealed and the pressure DEcreases, then the temperature DEcreased

0. 102 g of an unknown compound dissolved in 100. Ml of water has an osmotic pressure of 28. 1 mmhg at 20°c. Calculate the molar
Daniel [21]

The molar mass of the compound is 68 g/mol.

<h3>What is the molar mass?</h3>

The Osmotic pressure can be obtained from the relationship;

π= iCRT

π= osmotic pressure = 28.1 mmHg or 0.037 atm

i = Vant Hoff factor = 1

C = concentration = ?

R = gas constant = 0.082 atmLK-1Mol

T = temperature = 20°c + 273 = 293 K

C = π/iRT

C =  0.037/1 * 0.082  * 293

C = 0.0015 M

Now;

Number of moles = C/V = 0.0015/100 * 10^-3

= 0.015 moles

Number of moles = mass/molar mass

Molar mass =  mass/Number of moles = 0. 102 g/ 0.015 moles = 68 g/mol
