Finding Half-life or Doubling Time: Exponential Growth of Bacteria Example The population of a certain bacteria in a colony grows continuously at a rate of 15% per hour. Find the time it will take to double the population. Step 1:Identify the given growth or decay rate ...
Welcome to a tour of some of the recent advances in chemistry, taking in the cosmetic factory, the pharmacy, the grooming salon, the diet clinic, the power plant, the domestic cleaning company, and the art gallery along the way. Award-winning popular science writer John Emsley is our guide...
After having determined the equivalence point, it's easy to find the half-equivalence point, because it's exactly halfway between the equivalence point and the origin on the x-axis. Significance of the Half-Equivalence Point The Henderson-Hasselbalch equation gives the relationship between the pH ...
Omega-3 fatty acids are harder to find. Things like flax seeds, pumpkin seeds and walnuts are high in omega-3 fatty acids, as are salmon, trout and tuna. Current thinking is that these two fats need to be balanced in the diet at a ratio like 1-to-1 or 2-to-1, rather than the...
Chemistry is an essential branch of science that explores matter’s composition, structure, and properties and the changes it undergoes during chemical reactions. It plays a vital role in daily life, from medicine and environmental sustainability to technological innovation and industry. When it comes...
For a substance with a decay constant of 6.9×10−8s−1, how long would it take for 50% of the substance to decay? Use scientific notation and two significant digits. Step 1: Substitute the decay constant λ into the half life formula t1/2=ln(2)λ. We want to find the ...
How to calculate the rate of reaction in chemistry? The half-life of a reaction of compound A to give compounds D and E is 7.20 min when the initial concentration of A is 0.200 mol/L.How long will it take for the concentration to drop to 0.0400 mol/L if the reaction is a first or...

could host life -- all of them -- and we know that, and it's a strong possibility. And if we were going to find life on those moons and planets, then we would answer questions such as, are we alone in the solar system?
