Coal is made up of carbon, so burning coal releases carbon
When sodium chloride is formed from a positively charged sodium atom and a negatively charged chlorine atom, the charge on the salt becomes neutral is true
Explanation
Sodium ion ( positively charged) combine with chloride ion ( negatively charged) to sodium chloride which is neural according to equation below.
Na⁺ + Cl⁻ → NaCl (<em>neutral</em>)
Equal number of positive and negative charges add up to make neutral Nacl therefore the statement above is true.
Answer:
Bacteria and Archaea
Explanation:
The prokaryotes are classified into two domains, the bacteria and the archaea domains. This makes them unique as the other organisms fall into one of the three domains, not in two of them. The prokaryotes come in many different shapes. They all do fall into three categories, bacilli (which are the rod-shaped prokaryotes), spirilli (which are the spiral-shaped prokaryotes), and cocci (which are the spherical shaped prokaryotes).
A polar molecule has a positive and negative end because of electronegativity.
