Answer:
The positive charge in carbon is C
Explanation:
Atomic weight: An atom consists of protons, neutrons and electrons. Atomic mass is the sum of the number of protons and neutrons. The average weight of mass is called atomic mass of that atom.
The positive charge of an atom is proton.
The atomic weight of carbon = 12.0107 g/mol
Avogadro's number = 6.023×10⁻²³ atom/ mol
Charge = 1.602×10⁻¹⁹ C
The weight of carbon = 0.9 kg = 900 gram
Number of protons in carbon = 6
The positive charge in carbon is
=No. mole× Avogadro's Number× No. proton × charge per proton
C
Sorry, I’m not good with this stuff, but I think it’s Ti
The H3O in a solution is 12.57.
<u>Explanation</u>:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH.
pOH = -log[H3O]
pOH = -log(3.75x10^-2)
= 1.43
Now, pH = 14 - 1.43
= 12.57
The H3O in a solution is 12.57.
None since CO3 does not exist.
<span>Freezing of water is a physical change because all you are doing is changing the physical state of the water from a liquid to a solid. when freezing occurs you have not altered the water chemically. you still have water except its in the solid form.</span>
