Answer: 1 x 10^-12 M
Explanation:
pOH is the negative logarithm of hydroxide ion concentration in a base.
Mathematically, pOH is expressed as
pOH = -log(OH-)
where OH- is hydroxide ion concentration
So, 12 = -log(OH-)
(OH-) = Antilog (-12)
(OH-) = 1 x 10^-12 M
Thus, the concentration of the base is 1 x 10^-12 M
An ion has a positive or negative charge. While a covalent bond always has no charge, meaning it is neutral.
Answer:
If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.
If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.
Explanation:
The temperature of gases is a measure of the average kinetic energy of the molecules. With increasing temperature comes more kinetic energy for the gaseous particles. If temperature of the system is reduced, the particles will have less kinetic energy and would not be able to move. Temperature is directly proportional to average kinetic energy.
Pressure of gases increases when there is more frequent collision between their particles. The usual case is for gases to move more rapidly as a result of increase in kinetic energy of the system. The particles collides more frequently with one another and the walls of the container if the kinetic energy is raised.
Answer:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
