If a substance is a bad conductor as a solid, but a good conductor as a liquid or when dissolved into water, which type of bond is holding the compound together?
Answers
The bond type in the substance is ionic bonding because, ionic compounds in their solid state are not conducting but the ions they furnish when dissolved in water conducts electricity.
What are ionic compounds ?Ionic compounds are formed between metals and nonmetals. Metals are electropositive and they can easily loss electrons to from cations. Metals donate electrons to the electron deficient non metals to achieve octet.
Ionic bonding is a strong electrostatic force between opposite charged ions. Hence this bond is stronger than other types of bond. This intact bonding make them bad conductors in the solid state.
However they are electrically conducting the molten state or when dissolved in water due to the presence of free ions and electrons in the solution.

which type of cell is shown in the diagram - a plant cell, a yeast cell or a bacterial cell
Answers
Answer:
bacterial cell plant cells dont have a tail
Explanation:
The type of cell shown in the diagram is the bacterial cell as plant cell do not have tails while bacteria have tail.
Bacteria are prokaryotic unicellular organisms. They have a relatively simple cell structure compared to eukaryotic cells. They also do not possess any membrane-bound organelles such as a nucleus. However, do they possess genetic material (DNA or RNA) in the intracellular space called the nucleoid.
Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes. Prokaryotes are the dominant living creatures on Earth, having been present for perhaps three-quarters of Earth history and having adapted to almost all available ecological habitats.

How many moles of NaCl are in 2.35 liters of a 4.67 M solution?
Answers
There are 10.97 moles of NaCl in 2.35 liters of a 4.67 M solution.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles of a substance can be calculated by multiplying the molarity by the volume. That is;no. of moles = volume × molarity
According to this question, there are 2.35 liters of a 4.67 M solution. The number of moles is calculated as follows:no of moles = 2.35L × 4.67M
no of moles = 10.97mol
Therefore, there are 10.97 moles of NaCl in 2.35 liters of a 4.67 M solution.

C Earthquake
Explanation:
I just took this test and it’s on Quizizz
The event which best describes the model is an Earthquake. Earthquake is
formed when two plate boundaries collide with each other.
The plate boundaries colliding results in them being stuck. Pressure then
builds up between them which results in the plates breaking loose as time
goes on.
The movement that results from the plates breaking loose is what results in
an earthquake being experienced.

Answer:
In the first generation, the beetles with the dark spotted trait had a better chance of survival. The trait mutated over time, causing the beetles with that trait to be darker.
Explanation:
In the picture that I had, it shows that some of the beetles in the first generation started to develop spots on their back or wings. It shows that later down the line, their backs start to get even more darker which means that is must be a trait that mutated over time that would allow the beetles with that trait to be significantly darker. They can't just change their traits if they want to so it would have to be something like mutation that caused it.
