How many grams of calcium oxide will be produced in a closed vessel containing 20.0 kg of calcium and 20.0 kg of oxygen gas if the reaction goes to completion? (atomic mass of calcium = 40.1 amu)
Answer:
Explanation:
The mass of Calcium oxide that will be produced in a closed vessel is 27984.1311 g. The Number of moles is defined as given mass over molar mass.
Calculation of Number of moles:
Number of moles = Given mass / Molar mass
For Calcium :-
Mass of calcium = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of calcium = 40.078 g/mol
Thus,
Number of moles = 20000 g / 40.078 g/mol
Number of moles = 499.02 moles
For oxygen gas :-
Mass of oxygen gas = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of oxygen gas = 31.999 g/mol
Thus,
Number of moles = 20000 g / 31.999
Number of moles = 625.19 moles
According to the given reaction:
2 moles of calcium reacts with 1 mole of oxygen gas
Also,
1 mole of calcium reacts with 1/2 mole of oxygen gas
So,
499.0269 mole of calcium react with mole of oxygen gas
Moles of oxygen gas = 249.5135 moles
Available moles of oxygen gas = 625.0195 moles
Limiting reagent is the one which is present in small amounts. Thus, calcium is limiting reagent.
The formation of the product is governed by the limiting reagent. So,
2 moles of calcium produces 2 moles of calcium oxide
So,
1 mole of calcium produces 1 mole of calcium oxide
Also,
499.0269 moles of calcium produces 499.0269 moles of calcium oxide
Moles of calcium oxide = 499.0269 moles
Molar mass of calcium oxide = 56.0774 g/mol
Mass of calcium oxide = Moles × Molar mass = 499.0269 * 56.0774 g = 27984.1311 g
27984.1311 g of calcium oxide will be produced.

If prices rise by 1.5% a month, by how much will they increase over a full year? input your answer correct to two decimal places.
Answer:
18% in a year
Explanation:
We know that there are 12 months in a year. To to find the percentage of yearly increase, we just need to multiply the monthly percentage by the number of months in a year.
1.5% = 0.015
0.015 * 12 = 0.18
0.18 = 18%
So, the prices increase 18% in a year.

In a certain pentagon, the interior angles are $a^\circ,$ $b^\circ,$ $c^\circ,$ $d^\circ,$ and $e^\circ,$ where $a,b,c,d,e$ are integers strictly less than $180$. ("strictly less than $180$" means they are "less than and not equal to" $180$.) if the median of the interior angles is $61^\circ$ and there is only one mode, then what are the degree measures of all five angles?
The degree measures of all of these angles are 60, 61, 61, 179, 179.
How to solve for the angle measuresGiven that the 3rd largest angle that we have here is 61 degrees, the three angles are not going to be more than 183.
The sum of all the angles must be 540 degrees. The total of the largest of the numbers is less that 179 x 2 = 358 degrees.
The sum of the smallest three would be
540 - 358 = 182 degrees
Therefore the possible sets of these angles would be 60, 61, 61, 179, 179 degrees

Answer:
61, 61, 61, 178, 179
Explanation:
The five interior angles of any pentagon add up to 3*180= 540
If the median is 61, then we know the three smallest angles are each no more than 61, and so they add up to at most 3*61= 183 degrees. This means the two largest angles must add up to at least 540-183= 357 degrees. Since 178+179=357, and since the angles are all integers strictly less than 180, the only possibilities for the two largest angles are 178, 179 or 179, 179.
We consider these possibilities one at a time.
If the two largest angles are 178 and 179, then the three smallest angles add up to exactly 183, so they must each be exactly 61. Thus, one set of angles that satisfy the conditions in the problem is 61, 61, 61, 178, 179.
If the two largest angles are 179 and 179, then the three smallest angles add up to 182. The only way this can happen is for one of them to be 60 and the other two to be 61, but in this case, the set of angles would have more than one mode. So we can rule out this answer.
In conclusion, the five angles must be 61, 61, 61, 178, 179.
Music with a signature of three flats may very likely be in the key of _____.

A random drawing will determine which 3 people in a group of 9 will win concert tickets. what is the probability that you and your 2 friends will win the tickets? express your answer as a fraction in simplified form.
The probability that you and your 2 friends win the tickets is P = 1/84.
How to determine the probability?
There are 9 possible outcomes, 3 of which are you and your friends.
All of these outcomes have the same probability of being randomly selected, then the probability of winning is given by the quotient between the number of "outcomes" that you have and the total number of outcomes.
Let's say that the outcomes are pieces of paper with the names of the participants.
First draw:
In this one, there are 3 possible options that work, one is your paper, and the other two are for your friends.
So the probability is 3/9 = 1/3.
Second draw.
One of your group already won, so now there are 2 of you, and a total of 8 pieces of paper, so this time the probability is 2/8 = 1/4
Final draw:
Only one of you remains, and there is a total of 7 pieces of paper, this time the probability is 1/7.
The joint probability (of these 3 events happening in succession) is given by the product of the individual probabilities:
P = (1/3)*(1/4)*(1/7) = 1/84
