Formula of sodium phosphate = Na₃PO₄
So, one mole of sodium phosphate molecules have 3 moles of Na atoms
Then, 1.6 moles of Na₃PO₄ will have: 1.6 × 3 = 4.8 moles of sodium atoms will be present
The first one is the answer
isotopes of an atom have different number of neutrons . the number of protons are not different in isotopes of an atom
Answer:
Explanation:
Let the monoprotic acid be HX
HX ⇄ H⁺ + X⁻
pH = 2.53
Hydrogen ion concentration
Concentration of undissociated acid will remain almost the same as it is a weak acid
So
Ka = concentration of H⁺ x concentration of Cl⁻ / concentration of acid
= [ H⁺] x [Cl⁻ ] / [ HX]
= 5.24 x 10⁻⁴ M .
Batteries are everywhere. The modern world is dependent on these portable sources of energy, which are found in everything from mobile devices to hearing aids to cars.
But despite their prevalence in people's daily lives, batteries often go overlooked. Think about it: Do you really know how a battery works? Could you explain it to someone else?
Here's a rundown of the science behind the energy source powering smartphones, electric cars, pacemakers and so much more.
