Answer:

Mutualism is the doctrine that mutual dependence is necessary to social well-being.

Commensalism is an interaction between two organisms living together in more or less intimate association in a relationship in which one benefits and the other is unaffected.

Parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterized parasites as "predators that eat prey in units of less than one"

How many moles are contained in 2.3 liters of a 1.2M solution?

elena-s [515]

Answer:

$\boxed {\boxed {\sf 2.76 \ mol}}$

Explanation:

Molarity is found by dividing the moles of solute by liters of solution.

$molarity = \frac {moles}{liters}$

We know the molarity is 1.2 M (mol\liter) and there are 2.3 liters of solution. Substitute the known values into the formula.

$1.2 \ mol/liter= \frac {x}{2.3 \ liters}$

Since we are solving for x, we must isolate the variable. It is being divided by 2.3 and the inverse of division is multiplication. Multiply both sides by 2.3 liters.

$2.3 \ liters *1.2 \ mol/liter= \frac {x}{2.3 \ liters}* 2.3 \ liters\\2.3 *1.2 \ mol= x\\2.76 \ mol =x$

In a solution with a molarity of 1.2 and 2.3 liters of solution, there are 2.76 moles.

Planets close to a star will have __ orbital velocities than planets farther from a star.

Naddika [18.5K]

Answer:

The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
