Answer:1 mole of Mg3(PO4)2 (molecule) contains 3 moles of Mg atoms, 2 moles of P atoms and 2X4 moles of O atoms. = 0.03125 moles.
Explanation:
To solve this, we can use two equations.
t1/2 = ln 2 / λ = 0.693 / λ - (1)
where, t1/2 is half-life and λ is the decay constant.
Nt = Nοe∧(-λt) - (2)
Nt = amount of atoms at t =t time
Nο = initial amount of atom
t = time taken
From (1),
10 yr = 0.693 / λ
λ = 0.693 / 10 yr
From (2)
Nt = 100 g eΛ(-(0.693 / 10 yr) x 20 yr)
Nt = 25.00 g.
Hence, remaining mass will be 25.00 g
Answer:
"One mole of any gas has a volume of 24 dm3 or 24,000 cm3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas."
Explanation:
Divide the mass of neon.
Answer:
Acid salts are the converse of basic salts; they are formed in the neutralization reaction between a strong acid and a weak base. ... For instance, in the reaction of hydrochloric acid (a strong acid) with ammonia (a weak base), water is formed, along with ammonium chloride.
Order:
1. Make a Hypothesis
