Answer:

Protons

Explanation:

Electrons have a negative charge which are found in shells around the nucleus. The nucleus consists of protons and neutron and the neutron has a neutral charge.

1. How would you use your results to tell the relative ages of the rock layers in a new section of strata?

DanielleElmas [232]

Answer:

The more worn-out the rock is, the older it is

Explanation:

Hello,

The different layers a rock has could be useful to date it, as long as the deepest layers account for the oldest rocks because they haven been worn out due to erosion and others natural events. Thus, one can say that the more worn-out the rock is, the older it is when we want to analyze a new section of strata.

Best regards.

If the [H+] in a solution is 1 × 10–1 mol/L, what is the [OH–]? Show your work.

AVprozaik [17]

Hello!

The basic equations to solve this is
pH = -log[H+]
pOH = -log[OH-]
pH + pOH = 14
------------------------------------------------------------------------------------------------------
Find pH

pH = -log(1 * 10^-1)
pH = 1
------------------------------------------------------------------------------------------------------
Find pOH
1 + pOH = 14

pOH = 13
------------------------------------------------------------------------------------------------------
Find OH-
[OH-] = 10^(-pOH)
[OH-] = 1 * 10^-13mo/L

The answer is $[OH-] = 1 * 10^{-13} mol/L$

Hope this helps!

Why you cannot see the separete particles of a solute

Novosadov [1.4K]

Solutes are when a substance is dissolved into another substance, so if it's dissolved, it is combined completely, and you can't see it anymore :)

recall that temperature is a measure of the average kinetic energy of a substance. both ethanol and water had the same amount of

The same amount of added energy in water not increase its temperature as much as in ethanol because of temperature difference.

What is temperature?
The physical concept of temperature expresses in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using a variety of temperature scales, which historically defined various reference points as well as thermometric substances. The most popular scales are the Celsius scale, also known as centigrade, with the unit symbol °C, the Fahrenheit scale (°F), as well as the Kelvin scale (K), with the latter being primarily used for scientific purposes. One of the seven units inside the International System of Units is the kelvin (SI).

The average kinetic energy of all the atoms or molecules that make up a substance is how we define temperature in chemistry. A substance's constituent particles do not all possess the same kinetic energy. The distribution of the particles' kinetic energy at any particular moment can be used to describe it.
