Answer:
They differ in the available amount and rate they are used and replaced.
Explanation:
If one material is replaceable, then it's renewable. If it's not replaceable, then it's non-renewable.
The statement 'they differ in the available amount and rate they are used/replaced' provides an explanation of how renewable and nonrenewable resources differ.
What are renewable resources?Renewable resources can be defined can natural resources that can be renowned in nature in a given period of time.
These renewable resources include biomass and different types of energies (geothermal, wind, solar, etc). Conversely, non-renewable resources are specific resources from nature that cannot be replaced (e.g., coal).In conclusion, the statement 'they differ in the available amount and rate they are used/replaced' provides an explanation of how renewable and nonrenewable resources differ.

Dont worry about thinks that put you down and try to think about something that helps keep up your spirits. For example, thinks that you are proud of.
Try to think a little less of things like this, ¨Great, now we have a pandemic, now the world is going to end¨ but to thy think more of ¨Hey, this is a time where people need help the most, lets do our best to help them. I believe I can make the world a better place because I have the power of postivity.¨

Draw the Lewis structure for CF3PCF2 where all fluorines are bonded to a C atom
Answer:
See attached picture.
Explanation:
Hello.
As you can see on the attached picture, this Lewis structure requires all the elements to attain eight electrons after bonding, that is why the phosphorous is bonded with the two carbon atoms via a single bond with the carbon having the three fluorine atoms and a double bond with the carbon having the two carbon atoms.
Such arrangement is due to the fact that:
- P gets eight electrons by obtaining three from the two sided carbon atoms.
- The first carbon gets eight electrons from its initial four, three provided by each surrounding fluorine and one from the central phosphorous.
- Each fluorine gets eight valence electrons from their initial seven and one from the available carbon atoms.
Best regards.
What is the concentration of a dextrose solution prepared by diluting 15 mL of a 1.0 M dextrose solution to 25 mL using a 25 mL volumetric flask
Answer:
C₂ = 0.60 M
Explanation:
Step 1: Given data
Concentration of the concentrated solution (C₁): 1.0 MVolume of the concentrated solution (V₁): 15 mLConcentration of the diluted solution (C₂): ?Volume of the diluted solution (V₂): 25 mLStep 2: Calculate the concentration of the diluted dextrose solution
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 1.0 M × 15 mL / 25 mL
C₂ = 0.60 M
An aerosol can contains gas under a pressure of 2.0 atm at 20°C. Directions on
the can say that the can should be kept at less than 65°C. What would the
pressure in the can be at 65 °C?
Answer:
Explanation:
The volume is the same in both cases so the formula is
P1/T1 = P2/T2
T1 = 20 + 273 = 293 You have to convert Celcius to degrees Kelvin.
T2 = 65 + 273 = 338 degrees Kelvin
P1 = 2.0 atmospheres.
2.0 / 293 = P2/ 338
2*338 / 293 = P2
P2 = 676 / 293
P2 = 2.31 atmospheres
What is the molar mass of Mg(ClO4)2?
Answer:
223.21 g /mol
Explanation:
To find the molar mass (g/mol) of a substance, you have to add the amu's of all the elements together. First you have to determine how of element there are:
Mg=1, Cl=2, O=8. Now you multiply the amu of each element by the number of elements in the compound. Then add them together. The amu of an element and its molar mass are the same.
1(24.31 g/mol) + 2(35.45 g/mol) + 8(16.00 g/mol) = 223.31 g/mol
223.31 g/mol is the molar mass of the given compound. The molar mass of a material is a bulk attribute rather than a molecular one.
The ratio among the mass with the quantity of a substance (measured in mole) of any sample of a chemical compound is known as the molar mass (M) in chemistry. The compound's molar mass represents an average over numerous samples, which frequently have different masses because of isotopes. A terrestrial average as well as a function of the relative distribution of the isotopes of the component atoms on Earth, the molar mass is most frequently calculated using the standard atomic weights.
Molar mass=1(24.31 g/mol) + 2(35.45 g/mol) + 8(16.00 g/mol)
= 223.31 g/mol

A dog can run as fast as 15 miles per hour for a short distance. If a dog ran at this speed 0.10 of an hour, how far would it run?
Answer:
1.5 miles
Explanation:
Given that,
Speed of dog, v = 15 mph
Time taken by the dog, t = 0.1 h
We need to find the distance travelled by the dog. We know that, distance is the product of speed and time. So,
d=vt
[tex]d=15\times 0.1\\\\d=1.5\ \text{miles}[/tex]
Hence, the dog will cover a distance of 1.5 miles.

The density of aluminum is 2.7 g/cm3. A metal sample has a mass of 52.0 grams and a volume of 17.1 cubic centimeters. Could the sample be aluminum? EXPLAIN your answer.
Answer:
The given metal sample is not aluminum because its density is 3.0 g/cm³ while density of aluminum is 2.7 g/cm³.
Explanation:
Given data:
Density of aluminum = 2.7 g/cm³
Mass of metal sample = 52.0 g
Volume of metal sample = 17.1 cm³
which sample is that = ?
Solution:
The given problem will be solve through density formula.
d = m/v
d = density
m = mass
v= volume
Now we will put the values in formula.
d = 52.0 g/ 17.1 cm³
d = 3.0 g/cm³
It is given in question the density of aluminum is 2.7 g/cm³. The given metal sample is not aluminum because its density is 3.0 g/cm³.

For which of the following reactions is ΔH∘rxn equal to ΔH∘f of the product(s)? You do not need to look up any values to answer this question.
Check all that apply.
H2(g)+12O2(g)→H2O(g)
Li(s)+12F2(g)→LiF(s)
2Li(s)+F2(g)→2LiF(s)
Li(s)+12F2(l)→LiF(s)
2H2(g)+O2(g)→2H2O(g)
H2O2(g)→12O2(g)+H2O(g)
Answer:
Explanation:
Li(s)+1/2 F₂(g)→LiF(s)
In this reaction one mole of product is formed from gaseous state of reactants . So this reaction will represent the reaction for which ΔH∘rxn equals to ΔH∘f .
In other reaction one mole is not produced if we balance the reaction. The reactant must be in gaseous state . ΔH∘f . represents heat of formation . ΔH∘rxn represents heat of reaction .
You add 168.90 grams of NaCl to a container and then you add 616.00 grams of water to that same container What is the weight percent of NaCl in the containerI
Answer:
The weight percent of NaCl in the container is 21.5%
Explanation:
Given that,
Mass of NaCl = 168.90 gram
Mass of water = 616.00 grams
We need to calculate the weight percent of NaCl in the container
Using formula of percentage of weight
[tex]weight\ \%\ of\ component\ of\ the\ solution =\dfrac{weight\ of\ the\ component\ in\ the\ solution}{total\ weight\ of\ the\ solution}\times100[/tex]
Put the value into the formula
[tex]weight\ \%\ of\ component\ of\ the\ solution =\dfrac{168.90}{168.90+616.00}\times100[/tex]
[tex]weight\ \%\ of\ component\ of\ the\ solution=21.5\%[/tex]
Hence, The weight percent of NaCl in the container is 21.5%

0.68 moles of calcium to calcium atoms
[tex]0.68 \: moles \: calcium \times \frac{6.02 \times {10}^{23} \: calcium \: atoms }{1 \: mole \: calcium} \\ [/tex]
The (( mole calcium ))s are simplified so the answer is based on the number of calcium atoms.
[tex]0.68 \times 6.02 \times {10}^{23} = 68 \times {10}^{ - 2} \times 602 \times {10}^{ - 2} \times {10}^{23} \\ [/tex]
[tex] = 68 \times 602 \times {10}^{ - 4} \times {10}^{23} = 40936 \times {10}^{19} \\ [/tex]
[tex] calcium \: atoms = 40936 \times {10}^{19} \\ [/tex]
