The ideal gas law formula is: PV=nRT. As the n(moles of gas), R(Gas constant) and T(temperature) values are constant as it is given in the problem, we can calculate the pressure difference by the following formula: xΔP(difference factor of pressure)=1/xΔV. We can find the difference factor of volume by x=V(0)/v(1),
x=18l/2l=9 which means the pressure is 9 times greater after the volume is down to 2l. To find the final pressure, we can use P(1)=xP(0), when we add the numbers in, it looks like this: P(1)=9*42 kPa=378 kPa
Answer:
You should definitely consult your doctor for the serious brain damage caused.
Answer:
Sodium chloride (NaCl)
Explanation:
According to Arrhenius, an acid is a substance that dissociates to give protons, whereas a base dissociates to give hydroxide ions in an aqueous solution.
Therefore, a chemical reaction in which an Arrhenius acid reacts with an Arrhenius base to give salt and water, is known as a Neutralization reaction.
For example: <u>Neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH)</u>
A strong acid, hydrochloric acid (HCl) reacts with a strong base, sodium hydroxide (NaOH) to give salt, sodium chloride (NaCl) and water (H₂O).
<em>The chemical equation for this Neutralization reaction:</em>
HCl (acid) + NaOH (Base) → NaCl (Salt) + H₂O (Water)
<u />
<u>Therefore, </u><u>sodium chloride (NaCl) is the salt formed</u><u> during the chemical reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).</u>
Answer:B
Explanation:
The metals are to the left of the linethe nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.
The atoms of different chemical elements can be differentiated based on the number of protons.
Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).
The atomic number represented the number of protons in the nucleus of an element. For example:
- The element that has only 1 proton in his nucleus is Hydrogen atom.
- The element that has 2 protons in his nucleus is Helium atom.
<h3>What is an atom?</h3>
The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.
