Answer: Edmentum question:

The following graph shows the barometric pressure over the course of the day in Bellingham. What effect will this trend likely have on cloud cover and precipitation over the city?

a scatter plot showing the barometric pressure of an area, with air pressure on the y-axis and time on the x-axis

Explanation: edmentum answer:

In the graph, barometric pressure is decreasing. The drop in pressure represents a low-pressure system. This type of system will cause an increase in cloud cover and precipitation.

quester [9]

Answer:

The answer to your question is 144 kg

Explanation:

Data

Q = 8669 kJ

T1 = 75°F

T2 = 195°F

Cp = 0.897 J/(g°C)

m = ?

Formula

Q = mCp(T2 - T1)

Process

1.- Convert temperature to °C

T1 = (75 - 32) / 1.8

= 43/1.8

= 23.9°C

T2 = (195 - 32) / 1.8

= 163/1.8

= 90.6°C

2.- Solve for m

m = Q / Cp(T2 - T1)

3.- Substitution

m = 8669000 / 0.897(90.6 - 23.9)

4.- Simplification

m = 8669000 / 59.83

5.- Result

m = 144893.66 g or 144.9 kg

These diagrams show two atoms of fluorine and an atom of magnesium.

Diano4ka-milaya [45]

The magnesium atom looses two electrons which are accepted by each of the fluorine atoms. (Option D).

<h3>What is an ionic bond?</h3>

An ionic bond is formed when two ions are formed by the loss or gain electrons. In this case, magnesium has to loose two electrons while fluorine will gain two electrons.

Thus, the correct steps in the formation of an ionic bond between these atoms are A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion (Option D).
