Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.


Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

Carbonic acid is a mixture of

Fill a 100-milliliter container with 50 grams of sand. Fill a 100-milliliter container with 50 grams of cold tap water. Fill the last 100-milliliter container with 100 grams of cold tap water. Use the scale to measure the masses.

a scale measuring 100 grams of cold water in a 100-milliliter container, with 100-milliliter containers holding 50 grams of sand and 50 grams of cold water alongside
Pour all the ice cubes into a tub, and fill it with cool tap water to a depth of 2 inches. Place the sand and water samples in the ice water. Cover the entire tub.

three 100-milliliter containers in an ice bath inside a covered tub, with one container holding 50 grams of sand, one holding 50 grams of cold water, and one holding 100 grams of cold water
Every 15 minutes, remove the cover and check the temperatures of the samples using the three thermometers. Wait 30 seconds before recording the thermometer reading. Once the temperatures of the three samples are no more than a degree apart, record the temperatures.

B. Water will boil at a lower temperature on Venus than on Earth.
C. The temperature of water will remain constant while it boils.
D. The temperature of water will increase as it boils.

To clean their drain pipes, some people make a solution of baking soda and vinegar. Baking soda, also known as sodium bicarbonate (NaHCO3), reacts with acetic acid (C2H4O2) in vinegar. When these substances combine, the solution becomes colder, and sodium acetate (NaC2H3O2), water (H2O), and carbon dioxide gas (CO2) form. The gas creates bubbles that help clean the inside of the pipes. is this reaction endothermic or exothermic?

A food web showing the flow of energy through a freshwater ecosystem is shown below. Which of the animals shown in the food web is preyed upon by otters?

Which’s a mixture
A. Propane
B. Carbon
C. Gasoline
D. Ozone

ok so the question is Sort the processes based on the type of energy transfer they involve. condensation
freezing
deposition
sublimation
evaporation
melting and the catigoreies are thermal energy add or thermal energy removed.

Can someone please answer these 2 for me :)) I WILL GIVE BRAINLISTTTTT
