Explanation:
This law states that a still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it. Gravity and friction are forces that constantly push and pull the "stuff" on earth. So, when we roll a ball, it slowly comes to a stop.

How many moles of NaCl are in 2.35 liters of a 4.67 M solution?
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.

A teacher asks students to make a model of a transform plate boundary. The
students use blocks to represent tectonic plates and slide the blocks past each
other in the directions of the arrows as shown.
Transform Plate Boundary
Plate
Plate
Which event can the student best demonstrate with their model?
Answer:
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.

Calculate the vapor pressure (in torr) of a 35°C solution of ethanol and propanol where the mole fraction of propanol is .75. Assume Ideal behavior P°ethanol35=100torr P°propanol35=36torr
The vapor pressure (in torr) of a 35°C solution : 52 torr
Further explanationGiven
x propanol = 0.75
P°ethanol=100 torr
P°propanol=36 torr
Required
the vapor pressure
Solution
Raoult's Law
P solution = xA.P°A +xB.P°B
x ethanol = 1- 0.75 = 0.25
Input the value :
P solution = 0.25 x 100 + 0.75 x 36
P solution = 25 + 27
P solution = 52 torr

Answer: atomic nucleus
Explanation:
which type of cell is shown in the diagram - a plant cell, a yeast cell or a bacterial cell
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.

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?
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.

The input of cell systems share are glucose and oxygen. The output of cell systems share are carbon dioxide, energy and water.
What is a cell ?The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The chemicals that enter and leave the cell are governed by the cell membrane, which encloses the cell.
The cell membrane, the nucleus, and the cytoplasm are the three components that make up a cell. Intricate arrangements of microscopic fibers and hundreds or even thousands of tiny, unique structures known as organelles can be found in the cytoplasm.
The system's inputs are the signals or data it receives, and its outputs are the signals or data it sends. As part of an activity, the phrase can also be employed; for example, to "perform I/O" is to carry out an input or output operation.
Thus, The input of cell systems share are glucose and oxygen. The output of cell systems share are carbon dioxide, energy and water.
