7. Which atomic particle has a neutral (0) charge?

Column A

baherus [9]

Answer:

The Following are the matching to this question:

$1 \to c\\2 \to b\\3 \to a\\4 \to e \\5 \to d \\6 \to f$

Explanation:

It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.
Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.
Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.
The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.
The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.

Which answer lists the fundamental forces in order from strongest to weakest

laiz [17]

Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.May 22, 2013

How do you predict the geometrical shape of NH3 on VSEPR model

Sauron [17]

Answer:

NH3 Ammonia

Explanation:

Ammonia has 4 regions of electron density around the central nitrogen atom (3 bonds and one lone pair). These are arranged in a tetrahedral shape. The resulting molecular shape is trigonal pyramidal with H-N-H angles of 106.7°.

When the procedure calls for making a more dilute solution of an acid, or mixing an acid with other solutions, what is the corre

stiks02 [169]

Explanation:

Whenever we need to make a dilute solution of an acid then it is necessary to add water or non-acidic component into the acid first. This is because addition of water or non-acidic component directly into the acid could be highly exothermic in nature.

As a result, the acid can splutter and can cause burning of skin and other serious damage.

So, in order to avoid such type of damage the addition of water or non-acidic component into the acid actually helps to minimize the heat generated.

Thus, we can conclude that correct order of steps for making a more dilute solution of an acid is that either add all of the water or non-acid component first, or add a significant portion, before adding the acid to the mixture.

What is the ph of a buffer prepared by adding 0.809 mol of the weak acid ha to 0.608 mol of naa in 2.00 l of solution? The disso

Anarel [89]

The pH of the buffer is 6.1236.

Explanation:

The strength of any acid solution can be obtained by determining their pH. Even the buffer solution strength of the weak acid can be determined using pH. As the dissociation constant is given, we can determine the pKa value as the negative log of dissociation constant value.

$pKa=-log[H] = - log [ 5.66 * 10^{-7}]\\ \\pka = 7 - log (5.66)=7-0.753=6.247\\\\pka = 6.247$
