Hi !
1.the theological perspective of man's dominance in a dominant world was shown to be no longer tenable.
2. Heliocentricity uprooted the theological doctrine that the universe revolved around Man as the paramount and most glorious end-result of Creation, with the Sun, the Stars, the other Planets and the whole Universe .
Hood it helps and have a wonderful day!
the answer is solid, a liquid has a definitive volume but not shape, and a gas doesnt have a definitive shape nor volume
Answer:
41.63g
Explanation:
Given parameters:
Volume of CaCl₂ = 500mL = 0.5L
Concentration = 0.75mol/L
Unknown:
Mass of the solute needed = ?
Solution:
The mass of the solute can be derived using the expression below;
Mass = number of moles x molar mass
But,
Number of moles = Concentration x Volume
So;
Mass = Concentration x Volume x molar mas
Molar mass of CaCl₂ = 40 + 2(35.5) = 111g/mol
Mass = 0.75 x 0.5 x 111 = 41.63g
After 3 half lives it will be (1/2)^3 or 1/8 of original
so
1/8 times 10^8=1.25 x 10⁶ atoms left
153.888 grams are in 4.8 moles of sulfur
