Answer:
Yes. The volume would be 1/4 of the initial volume.
Explanation:
At constant temperature, the pressure of a gas is inversely proportional to the volume of the gas. Hence;
P1V1 = P2V2
<em>where P1 is the initial pressure, V1 is the initial volume, P2 is the final pressure, and V2 is the final volume.</em>
If the pressure of a gas is quadrupled;
P2 = 4P1, the equation becomes
P1V1 = 4P1 x V2
Making V2 the subject:
V2 = P1V1/4P1
V2 = V1/4
<em>This means that the volume would change by being reduced to </em><em>1/4 </em><em>of the initial volume.</em>
Answer:
Aqua regia is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum, though not all metals.
Explanation:
Yes it’s correct.
An ionic bond is the transfer of electrons from a metal to a non-metal.
Answer:
have the same number of protons
Explanation:
Atoms of the same element will always have the same number of protons.
Protons are the positively charged particles in an atom which are located in the nucleus.
- To recognize an atom, the number of protons is used.
- The number of protons is the atomic number.
- On the periodic table, atoms are arranged based on the number of protons.
