How to find the maximum amount of a substance that will dissolve using a graph?

1 answer:

8 0

Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

The answer is fight or flight response.
The activation of the sympathetic division would prepare people for "fight or flight" response.
The other names that are used for the fight or flight response are hyperarousal, response and the acute stress response.
There are two divisions in autonomic nervous system, one of the division is sympathetic division and the other one is parasympathetic division.

Why is a cell theory a theory and not a law

geniusboy [140]

Laws are very rare in science and they focus on simple, clear, and undisputed facts. A scientific theory is an explanation that is based upon the evidence that is available. With the theory of evolution, and many other scientific theories, the Cell Theory has extremely strong evidence to support it.
Hope this helps!

An electron with a charge of -1.6 × 10-19 coulombs experiences a field of 1.4 × 105 newtons/coulomb. What is the magnitude of th

kipiarov [429]

Answer:

$2.24 \times 10^{-14}$ Newtons

Explanation:

Magnitude of charge on the electron = q = $1.6 \times 10^{-19}$ Coulombs

The negative sign in the question statement indicates that the charge is negative.

Magnitude of Electric Field experienced by the electron = E = $1.4 \times 10^{5}$ Newtons/Coulomb

Magnitude of Force on the electron = F = ?

The relation between the charge, electric field and the force on the charge because of electric field is given by:

$E=\frac{F}{q}$

From here we can write:

F = qE

Using the values, we get:

$F = 1.6 \times 10^{-19} \times 1.4 \times 10^{5}\\\\ F = 2.24 \times 10^{-14}$

Thus, the magnitude of the electric force experience by the electron would be $2.24 \times 10^{-14}$ Newtons

Rocks within Earth both expand and contract as P waves pass

Explanation:

Rocks within the earth both expands and contracts as P-waves passes through them. P-waves are elastic waves.

Elastic waves behaves in such a way that they do not cause permanent deformation of rocks.
They can be said to cause elastic deformation when they travel through rocks.
They simply temporarily expand and contract the rock within a short period by causing the vibration of particles of the medium.
After a short while, the rock returns back to its original position as if nothing has happened to it.
These elastic waves are better called seismic waves.
P-waves are primary waves that can travel through any medium.
