33.0+101.05+1.00= 135.05g
Answer:
Number of moles = 0.05 mol
Explanation:
Given data:
Mass of Pb = 10.5 g
Number of moles of Pb = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of Pb is 207.2 g/mol.
Now we will put the values in formula.
Number of moles = 10.5 g/207.2 g/mol
Number of moles = 0.05 mol
It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions. One finds rock salt deposits ringing dry lake beds, inland marginal seas, and enclosed bays and estuaries in arid regions of the world
Answer:
OSMOSIS
Explanation:
Osmosis (/ɒzˈmoʊ.sɪs/) is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential (region of higher solute concentration),
Answer:
0.016 moles of product will obtain.
Explanation:
Given data:
Moles of K = 0.032 mol
Moles of product = ?
Solution:
Chemical equation:
4K + O₂ → 2K₂O
Now we will compare the moles of K with K₂O.
K : K₂O
4 : 2
0.032 : 2/4 ×0.032 = 0.016 mol
0.016 moles of product will obtain.
