Answer:
Valence
Explanation:
In an atom, the electrons at the outermost energy level is called as valence electrons. It is the valence electrons which participates and interacts with the other atoms and form bonds. The valence electrons of an atoms are important as they depict the chemical properties of an element.
Thus the valence electrons resides the outermost shell and surrounds the atomic nucleus.
Answer:
Both acids and bases are electrolytes which means that they're good conductors of electricity. Acids and bases both produce ions in water solution. Acids release hydrogen ions (H+) whereas Bases release hydroxide ions (OH-). The process of mixing acid or a base in water is an exothermic one.
Answer:
chemical change.
Explanation:
There are two types of changes in matter: physical change and chemical change.
physical change- it is a change in matter that alters only its physical properties or its physical appearance. This type of change is reversible. For example- freezing of water, the water turns into solid ice and it can be reversed by melting the ice.
chemical change- it is a change in matter that alter its chemical and thus its physical properties. Most chemical changes are irreversible. for example- burning of paper, results in black soot and ashes- Thus changing both physical and chemical properties.
Answer:
Mitosis results in two <u>diploid</u> daughter cells that have the same genetic makeup.
Meiosis results in four <u>haploid</u> cells that are all genetically different from each other.
Answer:
Spring tides occur when the sun, moon and earth are lined up, and it causes high and low tides to be much higher (moon is full/new). Neap tides occur when the sun, moon, and earth form a right angle this causes regular high and low tides to be much lower (first quarter and last quarter moon). The moons gravity and suns gravity pull the earths crust and ocean water.
