Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M

d. All of these
Explanation:
A timeline can be defined as a graphical representation of a series of important events in order in which they have occurred i.e in a chronological or sequential order. Thus, a timeline shows the order of events from top to bottom or left to right, starting with the earliest and moving forward to the most recent (latest).
Generally, a timeline is typically considered to be a cause and effect graphic organizer due to the fact that it illustrates events in a chronological or sequential order, their place in history, and how these events are interrelated or led to another.
This ultimately implies that, timelines show;
a. The order of events.
b. An event’s place in history.
c. Why an event may have taken place.
<em>For example, a timeline can be used to show the order in which the various battles fought during the American Revolutionary War occurred. </em>
Answer:
4pi/3
Explanation:
XY = YZ = XZ = 2
angle YXZ is pi/3
wxy is 2pi/3
Area of the circle = pi*r^2 = 4pi
Area of the shaded area = 4pi * (2pi/3)/(2pi) = 4pi/3
