The correct option is NONE OF THE ABOVE. T
The bases in the options above such as NaOH and KOH are strong hydroxides and they are strong bases. Examples of hydroxides that are weak bases are iron hydroxide, ammonium hydroxide, etc.
Sodium is a silver-colored metal which is soft enough to cut with a knife. It is an extremely reactive metal, and is always found naturally in ionic compounds, not in its pure metallic form. Pure sodium metal reacts violently (and sometimes explosively) with water, producing sodium hydroxide, hydrogen gas, and heat:
Chlorine is a poisonous, yellow-green gas, with a very sharp odor, a
Chemical change happen cuz these 2 elements will combine to form a new compound which’s NaCl ( table salt )
Answer:
Fe2O3(s) + 3CO(g) arrow 2Fe(s) + 3CO2(g) i think
Explanation:
Answer:
Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
n the scope of its subject, chemistry occupies an intermediate position between physics and biology.[5] It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.[6] For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).
Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are two types of chemical bonds: 1. Primary Chemical bonds e.g covalent bonds, in which atoms share one or more electron(s); ionic bonds, in which an atom donates one or more electrons to another atom to produce ions (cations and anions); Metallic bonds and 2. Secondary chemical bonds e.g. hydrogen bonds;Van der Waals force bonds, ion-ion interaction, ion-dipole interaction etc.

need thanks and make me brainiest if it helps you
Answer is: It can produced water that are needed by animals,plants and people
I really hoped it helped you out!!
