Answer:
Fossils, Glaciers, Coastlines.
Explanation:
Evidence of plate tectonic theory are fossils, fossils of the same species were found oceans apart. also glaciers evidence of glaciers were found in places with warm climates. coastlines coastlines look like they fit in a puzzle.
Pneumonia is an infection of the lungs caused by fungi, bacteria, ... These conditions include asthma, cystic fibrosis, diabetes, and heart failure.
Answer:
The structure is shown in the diagram.
Explanation:
Lewis structure : In order to draw Lewis structure we will calculate the total number of valence electrons in the molecule.
The valence electrons from Cl : 7
The valence electrons from O = 3 X 6 = 18
Charge negative so more electrons = 2
total electrons = 7 + 18 +2 = 27
Now we will distribute the electrons on each atom and in between atoms as shown in the diagram.
<span>The answer is true that Group 1A elements (except for hydrogen) are the
alkali metals. Groups 2A are alkaline earth metals. Group 3B-12B are transition
metals. Group 3A to 4A except Boron, Carbon, Nitrogen, oxygen, silicon,
phosphorus, sulfur, germanium, astatine, selenium, antimony, tellurium, polonium
are basic metal. Carbon, nitrogen, oxygen, phosphorus, sulfur and selenium are
nonmetals. Boron, silicon, germanium, astatine, antimony, tellurium and polonium
are metalloids. Groups 7A are halogens. Groups 8A are noble gases. The lower
part of the periodic table are lanthanides and actinides.</span>
