Answer:
The answer to your question is A. Ionic
Explanation:
There are 3 kinds of bonds in chemistry
a) Ionic bonds are the bonds between a metal and a nonmetal. Metals lost their electrons and nonmetals gain them. These bonds are the strongest so the melting and boiling points are the highest of all.
b) Covalent bonds are bonds between two nonmetals. The elements share electrons so these bonds are not as stronger as Ionic bonds, the melting and boiling points are high.
c) Metallic bonds are among metals and have high melting and boiling points.
Answer:
I think it's called the boiling point

Answer:
1. Qualitative.
2. Comparative investigation.
3. Mode.
Explanation:
1. Data collected that describes the quality of the data set is called qualitative data. This data type are non-numerical in nature i.e they are categorical. Some examples are excellent, poor, gender, religion etc.
2. An investigation where you compare objects to find a relationship is a comparative investigation. For example, a researcher trying to find out which bag is heavier by determining their weight.
3. If the number 5 occurs with the most frequency in the data set, it is called the mode.
For example, given A = (1, 5, 2, 5, 1, 5 4, 5). The mode is 5 because it appeared the most i.e four (4) times.
Given the data from the question, the mass of arsenic that contains 1.23×10²⁰ atoms is 0.0153 g
<h3>Avogadro's hypothesis </h3>
6.02×10²³ atoms = 1 mole of arsenic
But
1 mole of arsenic = 75 g
Thus, we can say that:
6.02×10²³ atoms = 75 g of arsenic
<h3>How to determine the mass that contains 1.23×10²⁰ atoms</h3>
6.02×10²³ atoms = 75 g of arsenic
Therefore,
1.23×10²⁰ atoms = (1.23×10²⁰ × 75) / 6.02×10²³ atoms)
1.23×10²⁰ atoms = 0.0153 g of arsenic
Thus, 1.23×10²⁰ atoms is present in 0.0153 g of arsenic
