What is the gram formula mass of Ca3(PO4)2

Chemistry
1 answer:
Georgia [21]3 years ago
6 0
Mass Molar of Ca_{3} (PO_4)_2
Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of Ca_{3} (PO_4)_2 = 120 + 62 + 128 = 310 g/mol

Therefore: <span>What is the gram formula mass of Ca3(PO4)2 ?
</span>Answer: 310 grams

Describe the relationship between"q" and energy in the melting of an ice cube.
klio [65]

Answer:

Now "q" is  the heat and energy is the capacity of any object or body ton perform any work. So we can relate them if we take the term specific heat in consideration.

As specific heat is the the amount of heat required to raise the temperature of an object in specific from one degree Celsius, for ice it is 2.108 kJ/kgK.

Explanation:

  • c = specific heat capacity,

  • q = heat

  • ΔT = change in temperature

So, we have:

  • C= Q/ΔT
  • It is the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object.

Which of the following atoms forms an ionic bond with a sulfur atom? (Points : 3)
elena-s [515]
Ionic bonds are formed when there is complete transfer of valence electrons between two atoms.

Electronegativity tells the trend of an atom to atract electrons.

You should search for the complete set of rules that indicate whether an ionic or covalent bond happens.

There are two relevant rules to state if whether an ionic bond will happen:

- When the difference of electronegativities between the two atoms is greater than 2.0, then the bond is ionic.

- When the difference is between 1.6 and 2.0, the bond is ionic if one of the elements is a metal.

You need to list the electronegativities of the five elements (there are tables with this information)

Element  electronegativity

Cu:    1.9
H:      2.2
Cl      3.16
I:        2.66
S:      2.58

Differences:

Cu / S: 2.58 - 1.9 = 0.68
H / S: 2.58 - 2.2 = 0.38
Cl / S: 3.16 - 2.58 =0.58
I / S: 2.66 -  2.58 = 0.08

 Those differences are too low to consider that the bond is ionic.

Then the answer is that none of those atoms forms an ionic bond with sulfur.

Both protons and neutrons (and their anti-particles) froze out:
VladimirAG [237]
I think Both protons and neutrons (and their anti-particles) froze out at 1013 K, about 0.0001 seconds after the Big Bang. Protons and neutrons are sub atomic particles of an atom that are found in the nucleus of an atom. Proton is the positively charge particle while the neutron has no charge. The proton positive charge accounts for the positive nuclear charge.
