The reaction between A and B is reactant favored. This inference can be drawn from the graph.
Chemical reactions occur all around us, including in our body's digestion of food and the creation of the sunlight's light. Understanding both chemical and physical alterations is crucial before starting any chemical reactions. The best illustration of a chemical and physical alteration is a burning candle. The reaction between A and B is reactant favored. This inference can be drawn from the graph.
Therefore, the correct option is option A.

You have 400,000 atoms of a radioactive substance. After 3 half-lives have past, how many atoms remain? Remember that you cannot have a fraction of an atom, so round the answer to the nearest whole number.
Answer:
Explanation:
The number of atoms that remains after 3 half-lives given that it was originally 300000 atoms is 37500 atoms
Data obtained from the question
Original amount (N₀) = 300000 atoms
Number of half-lives (n) = 3
Amount remaining (N) =?
How to determine the amount remaining
The amount remaining after 3 half-lives can be obtained as illustrated below:
N = N₀ / 2ⁿ
N = 300000 / 2³
N = 300000 / 8
N = 37500 atoms
3.20 g is the measurement of which of the following.
3.20 g is the measurement of mass.
Mass is a measure of the amount of matter in an object, and is typically expressed in grams (g), kilograms (kg) or pounds (lb). Mass is an intrinsic property of an object, meaning it is independent of its environment.
Mass is measured using a balance or scale, which compares the mass of an object to a known standard. In the case of 3.20 g, this would be the mass of an object compared to the mass of a reference object, such as a kilogram.

Based on the information, the solubility product of AgCl is 6.91 × 10^-10.
How to explain the informationThe common ion effect concerns the decrease in solubility of a salt when it comes into contact with another compound containing an identical ion within its make-up. This phenomenon is caused by the dependetics that arise from this shared element, which results in a decreasing amount of ions required for dissolving said salt. An illustrative instance is seen when observing the effects of calcium chloride (CaCl2) on calcium sulfate (CsSO4).
Named reactions constitute a subclass of chemical interchanges widely used within organic chemistry. These yield profound utilization due to their notorious titles attributed to notable scientists or related to other respective exploits; they are thus named following mannerisms peculiar to the substance itself.
