Answer:Atoms
Explanation: Democritus defined ATOMS as the indivisible, indescructible fundamental units of matter.
Answer:
atoms, the smallest pieces of elements that still retain their properties.
Explanation:
Use dimensional analysis to find the number of cm/min in 5.8 m/hr. Show your work. Be sure to calculate the answer in the correct number of significant figures.
Answer:
Explanation:
Q1. For assuring accuracy and precision we have to take into account statistical values such as absolut error, relative error and standard deviation. Errors(absolute and relative) are related to accuracy, and they tell you how much you are getting away from the correct answer. Standard deviation tells you how precisa your measure was, that means how many times you hit on the objective.
standard deviation can be added to the result as
Q2.
Q1: sort your numbers into numerical order so you can determine the highest and lowest measured values. and then subtract the lowest measured value from the highest measured value. Now determine that the answer is the precision.
Q2: In one meter there are 100 centemeter. Now you got 5.8 miles per hour which will become 580 centemeter per hour. In addition, there are 60 minutes in an hour. Based on what we know, 580 centemeters per hour will and should become 580/60 cm/min
Answer: Yes
Explanation: When powdered drink is mixed in the water, saturated solution will be formed. After some time, a point would come when the powdered drink would stop getting mix into the water. That point is known as saturation point. This point would give a clear solution as all the solute particles are dissolved in the solvent completely.
Now if we let all the liquid evaporate out of the pitcher, then we would be able to see only those particles which would not be dissolved into the solution completely.
Answer:
lithium chloride
Explanation:
Li=Lithium
Cl=Chlorine
The correct name for LiCl is Lithium Chloride. It's an ionic compound composed of Lithium and Chloride ions, arranged in a lattice structure with Chloride ions contacting each other across diagonally on the face of a unit cell.
The correct name for LiCl is simply Lithium Chloride. This is an ionic compound, which means it is composed of two ions: the lithium ion (Li+) and the chloride ion (Cl-). In this case, Li (Lithium) loses an electron and becomes a cation (Li+), whereas Cl (Chlorine) gains that electron and becomes an anion (Cl-). The compound LiCl is then formed from the electrostatic attraction between these ions.
On the face of a LiCl unit cell, Chloride ions contact each other across the diagonal of the face, showing the close packing arrangement of the ions in the lattice structure of the compound.
It's worth noting that the common naming system for these types of compounds is quite straightforward. The name of the positive ion (the cation) comes first (Lithium), followed by the name of the negative ion (the anion) with an -ide suffix (Chloride).

Answer:
Yes
Explanation:
The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur. The North pole always points the same way as the Earth revolves around the Sun.
Answer:
Yes!
Explanation:
The Earth takes 365.24 days to orbit the sun, as we move around the Sun during the year, the amount of light each area of the planet receives varies in length. When the Earth’s axis points towards the Sun it is summer and when the Earth’s axis points away from the sun it is summer. So while the sun is rotating in between the times of the 6mths to get from one season to the other we have spring and autumn. The earth’s movement around the sun causes the seasons, but it does not affect the temperatures during the seasons. Fun fact many people believe that the temperature changes based on the sun, however during the summer months the earth is further away from the sun in July and closest to the sun in January in the winter months.
