The average atomic mass of the element is the sum of the products of the percentage abundance of isotope and its mass number. Therefore, for atomic mass equal to 58.933, the most abundant isotope is cobalt-59. Thus, the answer is letter C.

Lelechka [254]

Answer:

The solution in beaker A is unsaturated

The solution in beaker B is saturated

Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at a particular temperature. An unsaturated solution is a solution that contains less solute than it can normally hold at a particular temperature.

If more solute is added to a saturated solution, the added solute does not dissolve completely. However, if more solute is added to an unsaturated solution, the added solute dissolves.

What volume (in L) of oxygen will be required to produce 77.4 L of water vapor in the reaction below?
Inga [223]

Answer:

90.3 L

Explanation:

Given data:

Volume of water produced = 77.4 L

Volume of oxygen required = ?

Solution:

Chemical equation:

2C₂H₆ + 7O₂  →  4CO₂ + 6H₂O

It is known that,

1 mole = 22.414 L

There are 7 moles of oxygen = 7×22.414 = 156.9 L

There are 6 moles of water = 6×22.414 = 134.5 L

Now we will compare:

                               H₂O           :              O₂    

                               134.5         :              156.9

                                 77.4         :             156.9/134.5×77.4 =90.3 L

So for the production of 77.4 L water 90.3 L oxygen is required.

Atoms are made up of protons, neutrons, and electrons.

Energy can be neither created nor destroyed.

Water freezes at 0°C

If  a piece of platinum is placed in acid, it will not react.

<h3>What are the correct pairing of the given terms?</h3>

The correct pairing of the given terms are obtained from the given options as follows:

Atoms of elements contains three sub-atomic particles which are protons, neutrons, and electrons.

Energy is the ability to do work.

According to the law of conservation of energy, Energy can be neither created nor destroyed.

Water is a liquid which freezes at 0°C.

Therefore, Water freezes at 0°C.

Platinum is a metal which is less reactive than hydrogen, Hence, it cannot displace hydrogen from acids.

Hence, if a piece of platinum is placed in acid, it will not react.

In conclusion, the correct pairing gives the correct description of the properties of the given terms.
