How does warmer planet causes ice to melt and then cause the warm up even more?
Answer:
Melting ice causes more warming.
Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere. This causes more global warming. In this way, melting ice causes more warming and so more ice melts.

Explain the law of conservation of mass and give an example that demonstrates it.
Answer:
Mass Cannot be created or destroyed. So everything that goes into a chemical reaction has to come out the other side, like cars driving into a tunnel. Any balanced equation of a chemical reaction is an example

In a reaction, the theoretical yield was 80 g, but the actual yield was 60 g. What was the percentage yield?
Answer:
75%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
60/80 = 0.75
0.75 x 100 = 75%
Answer:
33.34 %
Explanation:
Given that,
Actual yield = 60 g
Theoretical yield = 80 g
We need to find the percentage yield. It can be calculated as follows :
[tex]\%=\dfrac{Acutal-theoretical }{Actual}\times 100\\\\=\dfrac{60-80}{60}\times 100\\\\=33.34\%[/tex]
So, the required percentage yield is 33.34 %.

How many grams are in 2.0 x 10-5 moles of uranium?
Answer choices
5.3 x 10-3 grams
4.8 x 10-3 grams
1.4 x 10-3 grams
2.2 x 10-3 grams
The mass of 2.0 x 10-5 moles of uranium is 4.8 x 10-3 grams.
What is molar mass?The molar mass of a substance is the mass of 1 mole of the substance.
The molar mass of uranium is 238 g.
This is the mass of 1 mole of uranium.
The mass of 2.0 x 10-5 moles of uranium = 238 g × 2.0 x 10-5
The mass of 2.0 x 10-5 moles of uranium = 0.00476 g = 4.8 x 10-3 grams
Therefore, the mass of 2.0 x 10-5 moles of uranium is 4.8 x 10-3 grams.

its due tomorrow i wanna get the answer right pls.
Answer:
1) Without our atmosphere we wouldn't have life! The atmosphere protects our earth from letting harmful substances or rocks into our planet, which could cause damage.
2) You interact with the atmosphere in both good ways and bad. You interact by putting up things like flowers and trees, but in bad ways by releasing bad things (like carbon dioxide) and by light pollution!
3) The factors that can affect climate of an area, by latitude and longitude!

A balloon filled with helium has a volume of 30.0 L at a pressure of 100 kPa and a temperature of 15.0 C. What will the volume of the balloon be if the temperature is increased to 80.0 C and the pressure remains constant? (Hint: Use the Charles law equation)
Answer:
The final volume of the balloon is 24.480 liters.
Explanation:
Let consider that no leakages occur in the balloon during the isobaric process and that helium behaves ideally. From Equation of State for Ideal Gases, we construct the following relationship:
[tex]V_{o}\cdot T_{o} = V_{f}\cdot T_{f}[/tex] (1)
Where:
[tex]V_{o}[/tex], [tex]V_{f}[/tex] - Initial and final volume, measured in liters.
[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Initial and final temperature, measured in Kelvin.
If we know that [tex]V_{o} = 30\,L[/tex], [tex]T_{o} = 288.15\,K[/tex] and [tex]T_{f} = 353.13\,K[/tex], the final volume of the balloon is:
[tex]V_{f} = \frac{V_{o}\cdot T_{o}}{T_{f}}[/tex]
[tex]V_{f} = 24.480\,L[/tex]
The final volume of the balloon is 24.480 liters.
Convection currents slowly move tectonic plates across Earth
True or False?
Answer: True
Explanation: As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
Surface tension _____. A. Causes beads of water to spread out B. May be increased by detergents C. Is an inward force that tends to minimize the surface area of a liquid D. Is decreased by hydrogen bonding
Answer:
C. Is an inward force that tends to minimize the surface area of a liquid
Explanation:
Surface tension is a skin-like proper of water that is explained by its property or ability to form hydrogen bonds. The water molecule has the ability to bind the molecules from all sides that surrounds it. The force of action on each of the molecules is balanced. The surface tension is a more inward phenomenon and it holds the droplet in a spherical shape.Why can’t fossil fuels be replaced right away?
