Answer:
C. Yes, if each sample contains 6.02 x 10²³ atoms.
Explanation:
It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.
6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.
- If the amount of matter in the given substance is at least one mole, it is possible that they are made up of one mole each of each substance.
- If they contain lesser amount of atoms, then it is not up to one mole of substance.
- But if it is greater, then, we can have even more than one mole of substance.
A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.
Simple. The atomic number is the number of protons (12) and the mass number is the number of neutrons and protons combined. So you'd subtract 12 from 25 (25-12=) and that'd get you 13 as your answer. If you need to find the number of electrons, it'll be the same as the number of protons unless it has a certain charge and if it does, if it's positive it has more protons (+) than electrons (-), if it is negative it has more electrons (- negatively charged) than protons (+ positively charged)
<span>The correct answer is option 1. It is the carbon (C) atom that can bond with each other to form ring and chain structures in compounds. These ring and chain structures and compounds are called organic compounds. Chain structures include alkanes, alkenes, alkynes. Ring structures include cyclic hydrocarbons and aromatic hydrocarbons.</span>
<u>Answer:</u>
<em>A solution that has fewer neutrons than protons and more electrons than protons is a negative ion.
</em>
<u>Explanation:</u>
<em>Atoms in their original state have equal number of protons and electrons. The subatomic particles that take part in reaction are electrons.</em> When the electrons of an atom involve in a reaction an atom may lose or gain electrons and reach ionic state.
Ions can be positively charged or negatively charged and the charge acquired depends on whether electrons are gained or lost. The process of <em>losing electrons make an atom a positively charged ion and gaining electrons make an atom a negatively charged ion. </em>
<em>In this case the number of electrons is more than the number of protons which means there is an excess of negative charge and the atom has become a negatively charged ion.
</em>
