Do you think the density of the rock models affects the melting rate? Why or why not? I said no, but I need help on the part that says why or why not. Please use your own knowledge. Looking it up won't help. I have tried. :)

Answers

Answer 1

Answer:

1) Yes the density does affect it's melting rate.

Explanation:

Simply because the more rock the more time. For instance an ice cube that is empty inside ( has less density ) will take less to melt. Verses an ice cube that is ice to its inner core ( has more density ) will take more time to melt in the same temperature as the first ice cube.

6. An alloy of iron contains 75.0% iron and 25.0% other elements. How many grams of iron are present in 150. g of the alloy?

Answers

Answer:

108.5

Explanation:

half of 150 is 75 and half of that is 32.5. Add that to 75 and you'll get your answer

112.5 g of iron is present in the alloy.

From the question given above, the following data were obtained:

Percentage of iron (Fe) = 75%

Percentage of other elements = 25%

Mass of the alloy = 150 g

Mass of iron (Fe) =?

The mass of the iron present in the alloy can be obtained as follow:

[tex]Percentage = \frac{mass of element }{total mass }\\\\[/tex]

75% = [tex]\frac{mass of Fe}{150}[/tex]

[tex]0.75 = \frac{mass of Fe}{150}\\\\[/tex]

Cross multiply

Mass of Fe = 0.75 × 150

Mass of Fe = 112.5 g

Therefore, 112.5 g of iron is present in the alloy.

c.

d.
climate change

Answers

Answer: It is believed the major reason for the decline in amphibian species is death through disease.

Explanation:

The major reason for the decline in amphibian species is climate change.

Amphibians are organisms that can live on land and in water. They are

usually found around moist areas because they need water bodies to cool

off in order for their survival.

Climate change is characterized by an increase in temperature which

doesn't favor them as they lose more water which thereby threatens survival

and leads to their decline in the ecosystem.

According to the electronic configuration, element with lowest atomic mass is hydrogen.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Q1.What is the mass of 5 moles Of 1.Mg 2.CaCO3 Q2. Calculate the number of atoms in 10g of Na Q3.calculate the number of molecules in 10g of NaCl Q.4.What is Avogadro's number? How many number of atoms are present in 4g of Oxygen?

Answers

Answer:

Explanation:

Q1) as we know that moles=given mass/molar mass

     mass of 5 moles of Mg is

mass =moles*molar mass

mass=5*24

mass=120 g

mass of 5 moles of CaCO3 is

mass= moles*molar mass

mass=5*100=500

Q2) number of atoms in 10 g Na

first we need number of moles of sodium

moles =mass/molar mass

moles=10/23=0.43

now we know that moles=number of atoms /avogadro number

for number of atom the formula become

number of atom=moles*avogadro number

number of atom=0.43*6.023*10^23=2.6*10^23

Q3)number of molecule in 10 g of NaCl

again we need number of moles of NaCl

moles=given mass/molar mass

moles=10/58.5=0.17

now number of molecules=moles*avogadro number

number of molecules=0.17*6.023*10^23=1.02*10^23

Q4) avogadro number is the number of particles(atoms,molecules,ions) present in one mole of a substance its value is 6.023*10^23

Q5)Number of atoms in 4g of oxygen

again we need number of moles of oxygen

moles=mass/molar mass

moles=4/16=0.25

now number of atoms=moles*avogadro number

number of atoms=0.25*6.023*10^23 =1.5*10^23

Answer:

The answer is

3.68 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} [/tex]

From the question

mass of substance = 12.50 g

volume = 3.4 mL

The density of the substance is

[tex]density = \frac{12.50}{3.4} \\ = 3.676470588...[/tex]

We have the final answer as

3.68 g/mL
