The total installations they would have completed is 64 installations
<h3>Quantity & Rate </h3>
From the question, we are to determine how many total installations they would have completed
If the technician can complete an installation in 1.5 hours
Then,
In 60 hours, the technician will complete installations
= 40
Therefore, the technician would have completed 40 installations
- For the less experienced colleague
If it takes the less experienced colleague 2.5 hours to complete an installation
Then,
In 60 hours, the less experienced colleague will complete installations
= 24
Therefore, the less experienced colleague would have completed 24 installations
Hence, the total installations they would have completed is 40 + 24 = 64 installations

2.61 kilojoules of heat would be liberated by the condensation of 5.00 g of acetone
Explanation:
To convert grams into moles
We have 5.00 g acetone
Heat liberated = moles heat of vapourization
=0.0861 mol x 30.3 kJ/mol
= 2.61 kJ
Therefore, 2.61 kilojoules of heat would be liberated by the condensation of 5.00 g of acetone
Answer:
Basis and basic are two different words.
In English, Basis is used as a noun while basic is used as an adjective. Basis term refers as the base or starting point of any discussion.
For example: Bread is a basic ingredient of cake.
On the basis of Mendel's hypothesis.
In chemistry, Basis set is used as a set of functions that represent the electronic wave function in the density-functional theory which forms an algebraic equations that can be easily implemented on a computer.
While Basic term is used for substances that can accept a hydrogen ion (H+) from another substance and have pH above 7. such as sodium.
So, It is not important that both the terms, basis and basic change their English meaning if used in chemistry, they both can be used with English meaning in chemistry as well. Bases and basic, both the terms can be used as either English or Chemistry without affecting the meaning.
Answer:
3p^2
Explanation:
after filling 3s^2 only two electrons left out of 14 so the next sub shell is 3p therefore ,X represents 3p^2
Answer: 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal
Explanation:
To calculate the moles :
The balanced chemical equuation is:
According to stoichiometry :
4 moles of produce == 2 moles of
Thus 0.556 moles of will produce= of
Mass of
Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.
