Two new planets with equal masses are discovered. Planet A is twice as far from the sun as Planet B. Which of the following is t

rue?
A. The gravitational pull between Planet A and the sun is smaller than the gravitational pull between Planet B and the sun.


B. The sun's gravitational pull on Planet A is equal to its gravitational pull on Planet B because distance does not affect gravity.


C. The gravitational pulls between the sun and each of the planets are the same because the masses of the planets are the same.


D. The sun will attract Planet B and repel Planet A.

How many “p” orbital in principal energy level below?​
marshall27 [118]

Answer:

Each principal energy level above the first contains one s orbital and three p orbitals. A set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. Therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

Your computer is an example of which type of energy? Question options: Nuclear Kinetic Light All of the above
xz_007 [3.2K]

<u>Answer</u>:  Light

<em>Computer is an example of light energy which is the third option out of the given four choices. </em>

<u>Explanation:</u>

We know how a computer works it takes in <em>the electrical energy</em> and does a <em>lot of mathematical mechanical work</em> and for giving answers. It uses a screen on which light blinks in pattern such that it represents letters or mathematical numbers or expressions.

Hence by using this statement we can say <em>computer converts electrical energy into light energy. </em>

The following molecular equation represents the reaction that occurs when aqueous solutions of silver(I) nitrate and calcium chl
dsp73

Answer:

Ag+(aq) + Cl-(aq) —> AgCl(s)

Explanation:

2AgNO3(aq) + CaCl2(aq) —>2AgCl(s) + Ca(NO3)2(aq)

The balanced net ionic equation for the reaction above can be obtained as follow:

AgNO3(aq) and CaCl2(aq) will dissociate in solution as follow:

AgNO3(aq) —> Ag+(aq) + NO3-(aq)

CaCl2(aq) —> Ca2+(aq) + 2Cl-(aq)

AgNO3(aq) + CaCl2(aq) –>

2Ag+(aq) + 2NO3-(aq) + Ca2+(aq) + 2Cl-(aq) —> 2AgCl(s) + Ca2+(aq) + 2NO3-(aq)

Cancel out the spectator ions i.e Ca2+(aq) and 2NO3- to obtain the net ionic equation.

2Ag+(aq) + 2Cl-(aq) —> 2AgCl(s)

Divide through by 2

Ag+(aq) + Cl-(aq) —> AgCl(s)

The, the net ionic equation is

Ag+(aq) + Cl-(aq) —> AgCl(s)
