With a gas station on almost every corner, it’s hard to imagine life without fossil fuels. Fossil fuels power everything from ho

mes to businesses to cars. But fossil fuels are nonrenewable resources and have negative effects on the environment. To reduce our dependence on these fuels, cleaner energy alternatives have gained popularity in recent years.
One possible alternative is geothermal energy. Geothermal power plants drill deep wells underneath Earth’s surface to pump water that is heated by magma. The steam from this hot water spins a turbine that is hooked up to a generator that produces electricity. The cold water is then pumped back into Earth to be reheated.

Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of using this energy to power homes and businesses? Can you think of any consequences to communities or the surrounding environment?

Answer:

Its renewable

Explanation:

Geothermal energy is renewable as long as theres an infinite amount of magma to produce the energy. It is a rather expensive process, however, and can take up a ton of space. In my opinion, its a good source for energy if theres a cheap and easy way to tranfer the energy to homes

During an experiment, 575 mL of neon gas at 101 kPa were compressed in a cylinder to a volume of 144 mL.
Ne4ueva [31]

Answer:

403.3 kPa is the new pressure

Explanation:

This problem is solved by this formula:

P₁ . V₁ = P₂ . V₂

101kPa . 575 mL = P₂ . 144mL

(101kPa . 575 mL) / 144 mL = P₂

403.3 kPa = P₂

explain why metals are good thermal conductors and fluids are poor conductors of heat using the particle model theory of matter.
ratelena [41]

The reason is because Metals are strong metallic and they make good conductors for electric and heat. While fluids are non metals so they don't produce heat and most of the non metals are brittle and poor conductors.

When a meteor falls on earth. a streak of light is seen. will this streak of light be seen if a meteor falls on the moon? Explai
Lera25 [3.4K]

Answer:

No streak of light will appear.

Reason I given below.

Explanation:

No streak of light will be seen.

This is because as it falls to the moon, the gravitational pull plus the dense atmosphere which was necessary to produce friction when it fell to the earth are not present in this case and as such the whole meteor is not burnt like it did when it fell to the earth.

A 1.10 g sample contains only glucose and sucrose. When the sample is dissolved in water to a total solution volume of 25.0L, th
olga_2 [115]

Answer:

\large \boxed{79 \, \%}

Explanation:

I assume the volume is 2.50 L. A volume of 25.0 L gives an impossible answer.

We have two conditions:

(1) Mass of glucose + mass of sucrose = 1.10 g

(2) Osmotic pressure of glucose + osmotic pressure of sucrose = 3.78 atm

Let g = mass of glucose

and s = mass of sucrose. Then  

g/180.16 = moles of glucose, and

s/342.30 = moles of sucrose. Also,

g/(180.16×2.50) = g/450.4 = molar concentration of glucose. and

s/(342.30×2.50) = s/855.8 = molar concentration of sucrose.

1. Set up the osmotic pressure condition

Π = cRT, so

\begin{array}{rcl}\Pi_{\text{g}} +\Pi_{\text{s}}&=&\Pi_{\text{tot}}\\\dfrac{g}{450.4}\times8.314\times298 + \dfrac{s}{855.8}\times8.314\times298 & = & 3.78\\\\5.501g + 2.895s & = & 3.78\\\end{array}

Now we can write the two simultaneous equations and solve for the masses.

2. Calculate the masses

\begin{array}{lrcl}(1)& g + m & = & 1.10\\(2) &5.501g +2.895s & = & 3.78\\(3) & m & = &1.10 - g\\&5.501g + 2.895(1.10 - g) & = & 3.78\\&2.606g + 3.185 & = & 3.78\\ &2.606g & = & 0.595\\(4)  & g & = & \mathbf{0.229}\\&0.229 + s & = & 1.10\\& s & = & \mathbf{0.871}\\\end{array}

We have 0.229 g of glucose and 0.871 g of sucrose.

3. Calculate the mass percent of sucrose

\text{Mass percent} = \dfrac{\text{Mass of component}}{\text{Total mass}} \times \, 100\%\\\\\text{Percent sucrose} = \dfrac{\text{0.871 g}}{\text{1.10 g}} \times \, 100\% = 79 \, \%\\\\\text{The mixture is $\large \boxed{\mathbf{79 \, \%}}$ sucrose}
