Explanation:
The electron configuration of an atom means a detailed arrangement of the electrons in the atom in orbitals. It normally begins from the least energetic orbitals to the most energetic orbital.
For each of the elements, their electronic configuration in terms of the nearest noble gas is shown below;
P - [Ne] 3s2 3p3
I- [Kr] 4d10 5s2 5p5
Pb- [Xe] 4f14 5d10 6s2 6p2
F- [He] 2s2 2p5
(i) We start by calculating the mass of sugar in the solution:
mass of sugar = concentration × solution mass
mass of sugar = 2.5/100 × 500 = 12.5 g
Then now we can calculate the amount of water:
solution mass = mass of sugar + mass of water
mass of water = solution mass - mass of sugar
mass of water = 500 - 12.5 = 487.5 g
(ii) We use the following reasoning:
If 500 g solution contains 12.5 g sugar
Then X g solution contains 75 g sugar
X=(500×75)/12.5 = 3000 g solution
Now to get the amount of solution in liters we use density (we assume that is equal to 1):
Density = mass / volume
Volume = mass / density
Volume = 3000 / 1 = 3000 liters of sugar solution
I don’t understand the question
Answer:
12.5 gm left
Explanation:
30 minutes is THREE half lives
1/2^3 = 1/8th would be left
100g * 1/8 = 12.5 gm
The particles are given more energy and start to vibrate faster. In certain temps the particles vibrate so much that their ordered structure breaks down to the point the solid melts into liquid
