How do the types and numbers of atoms that repeat to make up a substance affect its properties?
Answers
Answer:
Chemical formula determines chemical structure and the properties of a substance.
Explanation:
The chemical formula of a substance depicts what atoms are in the substance, how many times they reoccur and in what ratio. Chemical formulas could be in form of: empirical, molecular or structural formula.
All of these determine the property of the substance, for instance in isomers of a compound.

I am a metalloid. I am in the nitrogen family and row 4. I have an atomic mass of 74.92. I can be used as a poison. Who am I?
Answers
Arsenic has an atomic mass of 74.92, is a well known poison, and a metalloid.
Answer:
As – Arsenic
Explanation:
Let's break this down step by step. Make sure you have a periodic table to reference.
"I am a metalloid" – We will be looking towards the right side of the periodic table. The possible choices are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and astatine (At).
"I am in the nitrogen family" – Families are elements grouped by columns. The nitrogen family is group 15. The possible choices are now arsenic (As) and antimony (Sb).
"and row 4" – Counting from the very top (don't forget row 1 of hydrogen and helium), we can see that arsenic (As) is in the 4th row.
"I have an atomic mass of 74.92" – Arsenic (As) does have an atomic mass of 74.92, which confirms our answer.
Hope this helps!

2. Make a 29 day timeline. Along the timeline draw and label the phases of the Moon starting with a full moon, crescent, first quarter, gibbous and full. Finish the second half showing the waning moons back to the new moon.
Answers
Dont know if this helps but here
Moon phases represent the names given to points in its orbit around Earth. Each phase lasts for only an instant as the moon constantly moves. To the naked eye, the full moon lasts about three days, but in reality, it is a full moon for just an instant before it begins to wane. The moon takes just under one month -- an average of 29 1/2 days -- to complete its phases.
TL;DR (Too Long; Didn't Read)
As the moon passes gradually and continually through its monthly cycle, each phase lasts only an instant. The Full Moon, for example, is simply a point halfway between waxing gibbous and waning gibbous.
Phases of the Moon
The moon has eight phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. But it is not as simple as dividing 29 1/2 by eight to find out how long each phase lasts. The fraction by which the moon is illuminated steadily increases or decreases at all times.
Primary and Intermediate Phases
The primary phases of the Moon cycle are the new moon, the first quarter, the full moon and the last quarter. The dates and times of these phrases -- which you can calculate or find on calendars -- change from month to month according to the positions of the Sun and the Moon. Astronomers refer to the crescent and gibbous phases as intermediate phases.

A)5
B) 12
C) 8
D) 7
Answers
Answer and Explanation:
D) 7 is the answer
Together, the crust and the upper part of the mantle form the lithosphere, Earth's solid outer shell. This rocky, brittle layer is broken up into seven major and several minor tectonic plates (also known as lithospheric plates) that fit together like puzzle pieces.
#teamtrees #PAW (Plant And Water)
The number of major plates that make up the most of the continents and the Atlantic and Pacific Ocean are seven.
What are major plates?When the upper solid shell part of the earth is break down then they will form major plates.
The major plates that are present on the earth are the African, Antarctic, Eurasian, North American, South American, India-Australian, and the Pacific plates.
Hence option (3) is correct i.e. 7.
