I would say the answer is emissions. These are the particles that are not supposed to be present in air but due to the production of different substances from humans daily activities these substances go with the air we breath. Hope this helped.
No because as the creation of the of the rock from the lava is considered construction not destruction
Answer:
molality of sodium ions is 1.473 m
Explanation:
Molarity is moles of solute per litre of solution
Molality is moles of solute per kg of solvent.
The volume of solution = 1 L
The mass of solution = volume X density = 1000mL X 1.43 = 1430 grams
The mass of solute = moles X molar mass of sodium phosphate = 0.65X164
mass of solute = 106.6 grams
the mass of solvent = 1430 - 106.6 = 1323.4 grams = 1.3234 Kg
the molality =
Thus molality of sodium phosphate is 0.491 m
Each sodium phosphate of molecule will give three sodium ions.
Thus molality of sodium ions = 3 X 0.491 = 1.473 m
Answer:
HF is the Arrhenius acid and KOH is the Arrhenius base.
Explanation:
An Arrhenius acid dissociates in water to form H+ ions in solution.
An Arrhenius base dissociates in water to form OH- ions in solution.
Write the equations by breaking the compounds into their elements
HF→ H⁺ + F⁻ HF produces H⁺ when added to water, so it is the acid.
KOH→ K⁺ + OH⁻ KOH produces OH⁻ when added to water, so it is the base.
