Shelley has a balloon with a small amount of baking soda in it. She fits the open end of the balloon over a graduated cylinder containing some vinegar. As she lifts the end of the balloon, the baking soda pours into the vinegar causing bubbling and fizzing to occur. Marie observes the balloon begin to "fill" up. Based on these observations, which of these can Marie determine about the new substance formed by mixing baking soda with vinegar?

How is density different from weight and mass?
Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.
Hope this helps :) if so, can I get Brainliest?
In the 1700s, Isaac Newton determined that the force of gravity between two objects depends on the mass of the objects and distance between them. He reasoned that things fall toward Earth because it has so much mass. Then in the 1900s, Albert Einstein worked with new discoveries, such as the fact that light always travels the same speed, and he determined a new explanation of how and why gravity works. Mass and distance still matter in Einstein’s explanation, but speed also matters. Newton’s explanation still works for objects close to Earth, but Einstein’s explanation works for all of the objects in the universe.
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?
Answer:

He (Helium) is _________ atomic molecule.
Answer:
Monatomic molecule
Explanation:
Each helium atom has 2 electrons, which is already the maximum no. of electrons that can fit in the first electron shell. When the outermost electron shell is full (2 for the first layer, 8 for others), the atom is stable.
Helium atom itself is already stable, so it doesn't need to combine with another helium atom to form a molecule, hence we call it monatomic.

Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?
Answer:
Explanation:
Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.
This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.
In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.
Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.
Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.
Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.

Describe how a pure sample of copper ( II ) nitrate crystals can be prepared using recycled copper wire
Explanation:
Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu(NO3)2(H2O)x. The hydrates are blue solids. Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C.[5] Common hydrates are the hemipentahydrate and trihydrate.
Copper ( II ) nitrate crystals can be prepared by reacting recycled copper wire with nitric acid so that chemical change takes place.The reaction is Cu + HNO₃\(\rightarrow\)Cu(NO₃)₂ +H₂O.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

What is one way these stems help these cactus plants survive?
A. They take energy from sunlight.
B. They take minerals from soil.
C. They hold the plant in the ground.
D. They make seeds for reproduction.
Answer:
B.
Explanation:
A cactus stores water in its stem, which allows it to survive and thrive in desert-like environments. Its stem is made up of thick, spongy tissue that helps to absorb and retain large amounts of water. This stored water is then used to keep the cactus hydrated during times of drought and heat.

Answer:
Dish C
Explanation:
In order to find which dish would make the food dish the hottest we need to find which dish out of the three options has the most enegrgy. We can find how much energy a dish has by couting the number for circles and multiplying it by the number inside the circles . For example, dish a has 11 cirlces and 30x11 is 330. Dish a has 330 unit of energy. If we repeat that process with the other two dishes we see that dish B has 110 units of energy and dish A has 350 units of energy. Since dish C has a larger amount of engery it willl make the food dish the warmest when stacked. The engery of the top dish, dish c, will flow down to the food dish in the form of heat. This process will then cointue warming the food dish and cooling dish C until they have thesame/similar levels of energy/temprature.

List the five physical phase changes of matter and give one example for each.
Answer:Melting.
Freezing.
Evaporation.
Condensation.
Sublimation.
Explanation:
Answer: Examples for the five transformations previously given.
For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.
