Suppose a mountain range is made up of 18 mountains, each mountain has
8800 trees on it, and each tree has 125,000 leaves on it.
How many leaves are
on all of the trees in the mountain range? Express your answer in scientific
notation.
The answer is 1.98 x 10^10 leaves.
18 mountains x 8800 trees = 158400 total trees
158400 total trees x 125000 leaves = 19800000000 total leaves in entire mountain range
Sci not: 1.98 x 10^10 leaves
To do scientific notation, put the decimal place right after the first digit in the number and count how many places are behind the decimal. you'll write the number of places after the decimal after the ^ in the 10^.
A rod of iron of uniform density has a thickness such that a one-inch-long segment of it weighs 3.88 ounces. Given that there are 0.035273 ounces in a gram and 2.54 centimeters in an inch, how many grams would a 14.79 cm length of the same iron rod weigh?
Answer:
Weight of 14.79 cm rod of iron = 640.51 gram (Approx)
Explanation:
Given:
Weight of 1 inch rod = 3.88 ounce
1 inch = 2.54 centimetre
1 gram = 0.035273 ounce
Find:
Weight of 14.79 cm rod of iron
Computation:
Weight of 14.79 cm rod of iron = 14.79[3.88/{(0.035273)(2.54)}]
Weight of 14.79 cm rod of iron = 57.3852 / 0.08959342
Weight of 14.79 cm rod of iron = 640.5068
Weight of 14.79 cm rod of iron = 640.51 gram (Approx)

which of the following substances does not conduct electricity
a)brass b)copper c)carbone(graphite) d)carbon(diamond)
Answer:
diamonds
Explanation:
Diamond does not conduct electricity.
• A form of carbon in which each of the atom of carbon is joined to four other atoms of carbon, giving rise to a giant covalent composition is a diamond.
• Due to this, diamond is very robust and exhibits high melting point. Thus, is used to cut tools.
• Diamond does not conduct electricity, due to the absence of delocalized electrons in the structure.
Thus, diamond does not conduct electricity. Option d is correct.

What is the volume of as sample that has a mass of 40.0 g and a density of 4.30 g/mL?
Explanation:
density = mass/volume so volume = mass/density = 40/4.30
The density of plutonium is 19.84 g/cm². What is its mass if the container has
volume of 250 cm?
Answer:
the answer is 7.936X 10⁻⁷kg.... the unit for volume must be cm³
Explanation:
we know,
ρ =m/v
given,
ρ =19.84/1000X(100)²= 1.984X10⁻⁶kg/m²
V (volume of the container means the volume of the element)=2.5 m³
NOW putting in the equation
1.984X10⁻⁶/2.5=m
or, m=7.936X 10⁻⁷kg(ANS)

Suppose 10 atoms of carbon (C) react with 20 atoms of oxygen (O). According to the Law of Conservation of Matter, how many atoms will there be in the product of this reaction?(1 point)
A) 20
B) 15
C) 10
D) 30
Answer:
D 30
Explanation:
whenever there is a reaction, the amount of atoms don't change, because matter can't be created or destroyed. Add the carbon and oxygen atoms together
According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
LAW OF CONSERVATION OF MATTER:
The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction. This further means that the amount of matter in the reactant of a reaction must equate that of the products. Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction. Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.Learn more: https://brainly.com/question/24996173?referrer=searchResults

- 1. Justin usually blows his nose using Kleenex tissues. His snot keeps leaking through the tissue. He decided he is going to create an experiment to find out if there is something better. What is his dependent variable? - A. Justin - B. Amount of snot the tissue can hold - C. Amount of tissue - D. Type of tissue
Answer:
B. Amount of snot the tissue can hold
Explanation:
In this specific scenario, the dependent variable would be the amount of snot the tissue can hold. That is because this is what Justin is trying to measure, which is also dependent on the type of tissue which would be the independent variable in this scenario. The different types of tissues can absorb different amounts of snot and this is what Justin ultimately wants to determine.
