Chemistry

Answer:

They all have the same density

Explanation:

Density is an intensive physical property, meaning that as long as the chemical formula is the same, that specific intensive physical property will be the same. For example. One kilogram of feathers has the same mass as one kilogram of bricks. Why? They both have a mass of one kilogram.

It's the same thing here. Since all the objects are (assumed to be) made up of 100% gold, they would all have the same density regardless of the mass. For extra points, say the density of each object is 19 \frac{g}{cm^3}.

Answer:

n = 0.01302 moles

Explanation:

Pressure = 1.3 atm

Temperature = 31 °C + 273 = 304 K ( Converting to kelvin temperature)

Number of moles = ?

Volume = 250 mL = 0.250 L

These quantities are related by the equation below;

PV = nRT

n = PV / RT

n = (1.3 * 0.250) / (0.0821 * 304)

n = 0.01302 moles

What zone does Earth exist in that potentially allows for life on our planet? Question 2 options: A: Red Zone B: Green Zone C: G
Triss [41]

Answer:

Goldilocks Zone

Explanation:

The habitable zone is the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.

Imagine if Earth was where Pluto is. The Sun would be barely visible (about the size of a pea) and Earth's ocean and much of its atmosphere would freeze. On the other hand, if Earth took Mercury’s place, it would be too close to the Sun and its water would form a steam atmosphere, quickly boiling off. The distance Earth orbits the Sun is just right for water to remain a liquid. This distance from the sun is called the habitable zone, or the Goldilocks zone.
