Of the $10$ kids in a chess club, $5$ are left-handed and $5$ are right-handed. the club holds a round-robin tournament in which
Nataliya [291]

The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 is the fraction of all games at the tournament Anita plays.

<h3>How to carry out Permutation and Combination?</h3>

We are given that there are 5 girls and 5 boys in a chess club.

Thus, total games that girls play against a boy = 5×5 = 25

The number of games a girl play against another is the total number of games = 10

The number of games that are boy vs boy = 10

The number of games Boy vs Boy + Girl vs Girl + Boy vs Girl = 10 + 10 + 25 =  45

Fraction of the games that are boy vs boy = 10/45 = 2/9

If Anita is one of the club members, then Anita will have to play against 9 people at the tournament.

Total number of games = 45

Then the fraction of all games at the tournament Anita play the game.= 9/45 ⇒ 1/5

Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays.

How much heat is absorbed when 2.8 mol nh4no3 is dissolved in water? the heat of solution of nh4no3 is 25.4 kj/mol.
Kay [80]

The heat absorbed when 2.8 mol NH₄NO₃  is dissolved in water is 71.96 kJ.

<h3>What is heat?</h3>

Heat is the transportation of energy to or from a thermodynamic system.

By the formula of heat

\rm (n) \times (delta\;Hrxn) = (qrxn)

Where n = moles

Delta Hrxn is molar heat

q = heat

Putting the values in the equation

\rm qrxn = (2.8 mol) \times(25.7 kJ/mol) = 71.96 kJ

Thus, the heat absorbed when 2.8 mol NH₄NO₃  is dissolved in water is 71.96 kJ.

In one Earth century (100 years), both Saturn and Earth will complete revolutions of the Sun. Which of the following
Vika [28.1K]

Answer:

Earth will complete more revolutions than Saturn.

Explanation:

It takes one year for the Earth to complete one revolution around the Sun. Our calendar is based on this fact, but some planets may finish one revolution around the Sun faster than us, while other planets will take more time to do it. For example, it takes Saturn 29 years to complete one revolution around the Sun, on the meantime, the Earth will have completed 29 revolutions.

Neptune is the planet that takes longer to complete one revolution around the Sun, approximately 164.79 years, while it takes only 88 days for Mercury to complete one revolution.
