Answer:
8
Explanation:
There are 8 atoms of Br because there are two molecules of 4 atoms of Br. 4 x 2 = 8.
Answer: 1 mol Br contains 6.022×1023Br atoms;its mass is 79.90 g.
Explanation:
: I mole or bromine refers to 6×10^23 molecules of bromine. But 1 molecule of bromine has 2 atoms. Hence the atom count will be exactly twice.

Which air mass brings high temperatures and precipitation to Gwinnett County in late spring?
Answer:
Climate of Georgia. Maritime tropical air masses dominate the climate in summer, but in other seasons continental polar air masses are not uncommon.
Explanation:
How do air masses flow?
from regions of low pressure to high pressure
it depends on the time of the day
from regions of high pressure to low pressure
whichever way the wind blows
How do air masses flow?
from regions of high pressure to low pressure
.
In general, cold air masses tend to flow toward the equator and warm air masses tend to flow toward the poles.

List 2 air masses and state what type of weather they cause.
Answer:
Maritime air masses form over water and are humid. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.

Geologists use the superposition and radioactive dating to determine the age of the Earth. Which statement correctly describes the use of one of these methods? Group of answer choices Using radioactive dating to determine the age of different rocks found in the desert. Using superposition to determine how many years old a river rock is. Using radioactive dating to determine the relative age of the Grand Canyon’s rock layers. Using superposition to compare the age of a rock to plant life in the area.
The correct statement that explained the use of one of these methods should be that using radioactive dating to determine the age of different rocks found in the desert.
Usage of radioactive dating:Radioactive dating refer to the method of dating rocks and minerals by using the radioactive isotopes.
This method should be useful for igneous and metamorphic rocks, that cannot be dated via the stratigraphic correlation method which is used for sedimentary rocks.
hence, The correct statement that explained the use of one of these methods should be that using radioactive dating to determine the age of different rocks found in the desert.

How many atoms of S are there?
examples of changing direction?
Answer:
All changes in motion (speed or direction) need an outside cause. Other examples would be a soccer player kicking a moving soccer ball so it changes direction, or a hockey player hitting a sliding puck with his stick so as to redirect it.
Explanation:
Which of the following are made mostly or entirely of proteins? (Select all that apply.)
fats
body tissues
carbohydrates
hormones
I think the answer is body tissue
Answer:
Body tissues/hormones
Explanation:
Excluding water and fat, the human body is made up almost entirely of protein. Protein is the main component of muscles, bones, organs, skin, and nails. Excluding water, muscles are composed of about 80% protein, making this nutrient especially important for athletes.
1) Protein hormones (or polypeptide hormones) are made of chains of amino acids. An example is ADH (antidiuretic hormone) which decreases blood pressure. 2) Steroid hormones are derived from lipids.
