*Answer:-*

The sun is about 1/3 the distance from the center of the Milky Way galaxy to its outer edges. It's located in a smaller spiral arm, between two large arms, called the Orion Arm.

<h3>Answer:</h3>

0.64 Moles of Propane

<h3>Explanation:</h3>

Data:

Moles of Carbon = 1.5 mol

Conversion factor = 7 mol C produces = 3 mol of Propane

Solution:

As we know,

7 moles of Carbon produces = 3 moles of Propane

Then,

1.5 moles of Carbon will produce = X moles of Propane

Solving for X,

X = (1.5 moles × 3 moles) ÷ 7 moles

X = 0.6428571 moles of Propane

Or rounded to two significant figures,

X = 0.64 Moles of Propane

At what temperature is water at its greatest density

ahrayia [7]

Answer:

$3.98^oC$

Explanation:

We usually approximate the density of water to about $1000 kg/m^3$ at room temperature. In terms of the precise density of water, this is not the case, however, as density is temperature-dependent.

The density of water decreases with an increase in temperature after the peak point of its density. The same trend might be spotted if the temperature of water is decreased from the peak point.

This peak point at which the density of water has the greatest value is usually approximated to about $4^oC$ . For your information, I'm attaching the graph illustrating the function of the density of water against temperature where you could clearly indicate the maximum point.

To a higher precision, the density of water has a maximum value at $3.98^oC$ , and the density at this point is exactly $1000 kg/m^3$ .

Explain how particles move before during and after melting

Aleksandr-060686 [28]

Answer:

Particles would move more freely, while still staying close together depending on the shape of the liquid

Explanation:

Melting is the process of going from a solid to a liquid due to the increase in heat/energy. This increase in heat/energy increases the speed at which the atoms within the object moves. Lets say we had an ice cube. While it is a cube, the particles inside the cube are slow and compact, staying close together.

When enough energy is gained, this makes the particles begin to move faster, gaining heat and energy which results in the ice cube melting and moving more freely than normal.

4.One rubber tire can generate about250,000 BTUS (1BTU=.0003KW ) when it is burned. The average American home consumes about 10,

jekas [21]

Answer:

The number of tires required to power ten homes for one year is approximately 2,730 tires

Explanation:

The given information are;

The energy generated by burning one rubber tire = 250,000 BTUs

1 BTU = 0.0003 kW

The amount of energy consumed by the average American home = 10,000 kWh

Therefore, the amount of energy generated by burning one tire in kW can be found as follows;

The energy generated by burning one rubber tire = 250,000 BTUs

1 BTU = 0.0003 kW

∴ 1 BTU × 250,000 = 250,000 BTUs = 0.0003 kW × 250,000 = 75 kW

We note that 250,000 BTUs is equivalent to 263764 kJ

1 kWh is equivalent to 3600 kJ

10,000 kWh = 10,000 × 3600 = 36,000,000 kJ

The energy requirement for ten homes for one year = 10 × 36,000,000 kJ = 360,000,000 kJ

At 50% efficiency, the energy produced per tire = 0.5 × 263764 kJ = 131,882 kJ

The electrical energy produced per tire = 131,882 kJ/tire

The number of tires required to power ten homes for one year = 360,000,000 kJ/ 131,882 kJ/tire = 2,729.71293 ≈2,730 tires

The number of tires required to power ten homes ≈2,730 tires.
