Explanation:
The volume of a bottle is 500cm. what is the volume of the bottle in millimeters
Answer:
5000mm
Explanation:
10mm makes 1 cm
so if we compare them:
10mm-->1cm
x -->500cm
now cross multiply:
1x-->5000
divide both sides by 1 for x to be alone
therefore we get x=5000
Witch zone contains plenty of sunlight for photosynthesis
Answer:
well maybe it is open ocean (or the euphotic zone, witch is not an answer choice)
Explanation:
The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here. The sunlit zone goes down to about 660 feet.
What is the density of a 500g box whose volume is 67 ml?
Answer:
7.46 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 500 g
volume = 67 mL
We have
[tex]density = \frac{500}{67} \\ = 7.462686[/tex]
We have the final answer as
7.46 g/mLHope this helps you

5. Element X has two isotopes: X-100 and X-104. If the atomic mass of X is 101
amu, what is the relative abundance of each isotope in nature?
Answer:
The abundance of X-100 is 75 percent, and X-104 has an abundance of 25 percent. The answers are found by solving two equations with two unknowns, which are A plus B equals 100, and 100A plus 104B equals 10,100.
The relative abundance of each isotope in nature
X-100 = 75%
X-104=25%
By dividing the total number of ions identified by the number of ions with a particular m/z m/z m/z ratio, one may determine the relative abundance for each individual ion in the sample.
How can the abundance of two isotopes be determined?
For chemistry problems involving relative abundance, use the following formula:
(M1)(x) + (M2)(1-x) = M (E)
Find the relative abundance of the isotopes if one nitrogen isotope, nitrogen-14, has a mass of 14.003 amu and another, nitrogen-15, has a mass of 15.000 amu.
Algebra can be used to find x. ...
x = 0.996

How does heat affect solubility of solids in a liquid?
A. The particles of a solid lose their shape and do not dissolve properly when heated
B. Solubility is not affected by heat.
C. Solubility generally decreases with heat.
D. Solubility generally increases with heat.
Answer:
Option D
Explanation:
Solubility is the amount of a substance in a solvent that dissolves at a specific temperature. So knowing this you would know that generally when you increase the temperature it also increases the solubility of a substance which means the answer is option D or "Solubility generally increases with heat."
Hope this helps.
Answer:
D.) Solubility generally increases with heat

Explanation:
KI + Pb(NO3)2 → Pbl2 + KNO3
This chemical reaction represents the reaction of
potassium iodide (KI) and lead nitrate (Pb(NO3)2) to
form lead iodide (Pbl2) and potassium nitrate (KNO3).
When correctly balanced, the coefficient for lead iodide
will be_________.
Select one:
3
6
2
The balanced for the reaction is:
2KI + Pb(NO₃)₂ → Pbl₂ + 2KNO₃
When the equation is balanced, the number of atoms for each element on both the reactant and product sides of the equation are equal. This can be seen below:
Reactant Product
K 2 2
I 2 2
Pb 1 1
N 2 2
O 6 6

what is meant by dative covalent bond
A coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction. This type of interaction is central to Lewis theory.

How many moles of carbon atoms are there in
5g of carbon?
Answer:
12 atoms of carbon
Explanation:
(6.023X10^23)/12 atoms of Carbon.
There are 0.42 moles of carbon atoms in 5g of carbon.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles in a substance can be calculated by dividing the mass of the substance by its molar mass. That is;no. of moles = mass (g) ÷ molar mass (g/mol)
According to this question, the mass of carbon is 5g. The molar mass of carbon is 12g/mol.No. of moles = 5g ÷ 12g/mol
No. of moles = 0.42moles
Therefore, there are 0.42 moles of carbon atoms in 5g of carbon.

How many moles are there in 8.94*10^24 atoms P?
Answer:
14.85 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{8.94 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.850498[/tex]
We have the final answer as
14.85 molesHope this helps you
