Answer:
(c) Li2SO4(aq) → 2Li+(aq) + SO4 2-(aq)
Explanation: Lithium atom donates electron to be more electropositive, while, sulphate ion accept electron to become more electronegative.
Answer:
C3H6O
Explanation:
Data obtained from the question. This includes:
Carbon (C) = 0.62069 g
Hydrogen (H) = 0.103448 g
Oxygen (O) = 0.275862 g
The empirical formula can be obtained as follow:
Step 1:
Divide by their molar mass.
C = 0.62069 / 12 = 0.0517
H = 0.103448 / 1 = 0.103448
O = 0.275862 / 16 = 0.0172
Step 2:
Divide by the smallest number.
C = 0.0517 / 0.0172 = 3
H = 0.103448 / 0.0172 = 6
O = 0.0172 / 0.0172 = 1
Step 3:
Writing the empirical formula.
The empirical formula is C3H6O
The correct answer is A. apples coming in many different varieties.
This is because people who grow apples mix different kinds of apples in order to produce new ones, which means they are selecting the qualities they want the new apple to have in order to get the best results. B, C, and D are incorrect because that is the normal behavior or appearance of these animals - there is nothing extraordinary about them that was created thanks to selective breeding..
Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand
