Answer:

Because of the revolution of the moon about the earth.

Explanation:

The moon is the natural satellite of the earth; which rotates about its axes and orbits around the earth. As the moon orbits the earth with respect to time, it would complete a revolution in 27.3 days.

During revolution, different phases of the moon can be observed by someone on the earth. This is due to its location at different time during the process. Therefore, Jorge was able to see different phases of the moon because of its revolution about the earth.

Which of the following is the correctly balanced chemical equation for the reaction of Ca(OH)2 and HNO3?
sattari [20]

Explanation:

The reaction between calcium hydroxide and nitric acid is as follows.

  Ca(OH)_{2} + HNO_{3} \rightarrow Ca(NO_{3})_{2} + H_{2}O

Number of reactant atoms are as follows.

  • Ca = 1
  • O = 4
  • H = 3
  • N = 1

Number of product atoms are as follows.

  • Ca = 1
  • O = 4
  • H = 2
  • N = 3

To balance the given chemical equation, multiply HNO_{3} by 2 on reactant side and multiply H_{2}O by 2 on the product side.

Therefore, the balanced chemical equation will be as follows.

    Ca(OH)_{2} + 2HNO_{3} \rightarrow Ca(NO_{3})_{2} + 2H_{2}O

Re-order each list of elements in the table below, if necessary, so that the elements are listed in order of decreasing electron
Artyom0805 [142]

Answer:

O, S, Te

Cl, Br, Se

Explanation:

Main group elements have an electronegativity that increases across a period (from left to right) and decreases down a group.

Each atom has its own value which you can find on the electronegativity chart.

Metals have low values

Nonmetals have high values

I'm your case:

O = 3.5

S = 2.5

Te = 2.1

Cl = 3.0

Br = 2.8

Se = 2.4

posledela
A) Answer D. Clouds forming high in the atmosphere are referred to as cirrus, cirrostratus, and cirrocumulus. 

B) Clouds tend to form at higher altitudes because as<span> air rises, the moisture in it slowly reaches its saturation point and when this happens, tiny crystals of water start to condense and form clouds.

C) Precipitation: Water that falls to the ground from clouds, such as in rain, snow, sleet, or hail.</span>
