Nuclear fission is the splitting of the atomic nucleus into more nuclei. The product of the californium atom fission is palladium,¹¹⁴₄₆Pd.
What is nuclear fission?Nuclear fission is the breakdown of the atomic nucleus into two or more atomic nuclei including the gamma photons that release high energy.
The californium atom will absorb a neutron and release two small nuclei and three neutrons.
We know,
The atomic number of californium atom (Cf) = 98
The atomic mass of the californium atom (Cf) = 252
The atomic number of Tellurium (Te) = 52
The atomic number of Tellurium (Te) = 136
The atomic mass of the unknown element is calculated as:
[(252 + 1) - (136 + 3)] = 114
An atomic number of the unknown element is calculated as:
98 - 52 = 46
Hence, the unknown element is palladium (Pd) as it has atomic number 46.
The nuclear fission of the californium atom is shown as:
[tex]\rm ^{252}_{98}\; Cf + ^{1}_{0} n \;\rightarrow \;^{114}_{46}\;Pd +^{136}_{52}\;Te +3^{1}_{0}\;n[/tex]
Therefore, palladium is the missing element of the reaction.

Based on the Mohs hardness scale corundum, quartz, calcite, and gypsum are minerals listed from hardest to softest. Thus, option D is accurate.
What is the Mohs scale?Minerals are inorganic compounds that have characteristic structures and physical forms. The hardness and the softness of the minerals are estimated by the Mohs hardness scale.
Hardness is the physical characteristic that defines the resistance level of getting penetrated and scratched. According to the scale, the level of hardness is corundum (9), quartz (7), calcite (3), and gypsum (2).
Therefore, option D. corundum, quartz, calcite, and gypsum are minerals listed from hardest to softest.

The experimental probability of rolling an odd number is %, which is % more than the theoretical probability.
Of the twenty times in this experiment the following are prime (3,5,2,7,3,7,2,2,7,3,3,5) or 12 of the twenty
12/20 = 6/10 = 60%
So 60% is the experimental probabilty.
The theoretical probability given that there are four prime numbers (2,3,5,7) out of 8 on the dice should be 50% because 1/2 of the numbers are prime.
The experimental probability is 10% more than the theoretical probability

A manager drew this box-and-whisker plot to represent the ages of her 23 employees. every employee is a different age.
Answer:
Explanation:
About 5 employees have ages that are older than 54 years.
What is a box plot?
A box plot provides the summary of a data using the five number summary that is minimum, lower quartile, median, upper quartile and maximum.
From the diagram, the third quartile is 54 years. Hence 75% of the employees are between 35 to 57 years.
25% are older than 54 years, hence:
Employers older than 54 years = 25% of 23 employees = 5.75
About 5 employees have ages that are older than 54 years.

Of the 318 sophomores, 140 are taking algebra 2 and 102 are taking chemistry. of those that are taking chemistry, 76 are not taking algebra 2. if a sophomore is chosen at random, find the probability that they are taking algebra 2, if it is known that they take chemistry.
The probability that the sophomores are taking algebra 2 is equal to 0.63.
How to find the probability?In order to determine the probability that the sophomores are taking algebra 2, we would calculate the number of sophomores that takes algebra 2 but not chemistry and those that do not take chemistry.
For algebra 2 but not chemistry, we have:
Algebra 2 but not chemistry = 140 - 76
Algebra 2 but not chemistry = 64.
For those not taking chemistry, we have:
Not taking chemistry = 318 - 102
Not taking chemistry = 216.
Now, we can find the probability that the sophomores are taking algebra 2:
P(A) = 64/102
P(A) = 32/51
P(A) = 0.63.

Tim wants to buy a new subcompact car, which costs $20,000. he will pay a down payment of 10 percent and finance the rest at 12 percent. if he finances the vehicle over 5 years, how much will his total finance charge be?
Based on the calculations, Tim's total finance charge would be equal to $12,048.
What is total finance charge?The total finance charge can be defined as the amount of interest and other expenses which a customer would have to pay a lender, for borrowing an amount of money (credit).
In this scenario, Tim's monthly payment would be equal to $800.80 and after five (5) years, the total amount of money he'll pay is given by:
Total amount = $800.80 × 12 × 5
Total amount = $48,048.
For the total finance charge, we have:
Total finance charge = Total amount - Principal
Total finance charge = 48,048 - 36,000
Total finance charge = $12,048.
