Answer:
If the pKa of the acid is low (negative), then the acid is strong.
Explanation:
Ka, <em>the acid ionization constant, </em>measures the strength of an acid in a solution. Stronger acids have higher Ka values.
We defined: pKa = -log[Ka]
This function is a decreasing function, meaning that pKa will be getting smaller and smaller, while increasing Ka (high values of Ka will have negative pKa values). Therefore, stronger acids (high values of Ka), will have low (negative) pKa values.
Answer:
the word subcellular means contained within a cell. at a level of organization lower than the cellular.
Explanation:
Answer: A woman kicks a soccer ball and scores a goal.
Explanation:
Potential energy: it is the energy possessed by the body due to its position.
Kinetic energy: it is the energy possessed by the the body due to its motion.
When a woman kick's a soccer ball she transferred her potential energy to soccer ball.Due to this action soccer ball comes into motion which means potential energy imparted to the ball starts getting converted into kinetic energy.
Answer:
The goal of Science is to expand knowledge.
Explanation:
By the second law of thermodynamics:
Heat can not spontaneously flow from cold regions to hot regions without external work being performed on a system.
Heat transfer is the passage of thermal energy from a hot ( t B = 80° C ) to a colder body ( t A = 40° C ).
Answer: B ) Heat flows from object B to object A.
