Answer: b

Explanation:

Answer:

Steel Wool + Oxygen (Fire)  The steel wool is a grayish color and has a rough surface. Oxygen is transparent  It looks like a powder, and like if it was rusted steel wool but then broken apart and turned into a powder  Well Iron oxide is 7 grams and steel wool combined is 7 grams so you can say that the mass was conserved  Yes, this is a chemical change because the steel wool rusted and rust is a chemical change, so iron oxide causes because if a physical change.

Egg + Heat  The egg has a yellow yolk in the middle while there is some type of liquid at the border of the yolk, but it is clear, the heat is hot but transparent  The egg turned into a delicious food called an omelet what was yolk staid as a liquid but got a tad harder, but the transparent border around it turned white  It was conserved because the eggshell was 4 grams and the fried egg is 41 grams  It is a chemical change because it results in the formation of new particles, and the chemical bonds break up and new ones are formed.

Water + Heat  The water is a clear liquid, while the heat is very hot but transparent  The water turned into a type of oxygen -Water Vapor-   If 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor.  There was no chemical reaction because the water vapor can be turned back to water also it just changed from a liquid to a gas and did not change its composition  

Zinc + Hydrogen Chloride  Zinc: a white/silver metallic solid. Hydrogen chloride (dilute hydroelectric acid) is a transparent, colorless liquid with a very low pH (acidic). Zinc "dissolved" in hydrogen chloride, while emitting a colorless gas.  The liquid remains a colorless liquid, possibly still having a low pH from the unused acid. The colorless gas collected in a test tube gives a popping sound when ignited with a burning wooden splint, so it is not air embedded in the zinc, nor dissolved in hydroelectric acid.  Well although the zinc chloride is 12 grams and not 15 the gas that was released was 3 grams and as we all know 3 + 12 is 15 so you could say that the mass was conserved The production of a new substance (most probable hydrogen) from the reaction of the two reactants. When a few drops of the liquid product are evaporated on a watch glass, a white residue is left.  When a few drops of the liquid hydroelectric acid are evaporated on a watch glass, there is no residue. This proves that a new product (hydrogen gas), (white powder, zinc chloride) is produced instead of zinc being physically dissolved in hydroelectric acid.

Sodium Hydroxide + Copper Sulfate  Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals. When their solutions are mixed, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulfate will be formed. The sodium hydroxide and the copper sulfate combined to make a total of 67 grams and the product is split because the sodium sulfate is 47 grams and the copper hydroxide is 20 grams but altogether it is still 67 grams so you could say that the mass was conserved The proof of the reaction is the appearance of pale blue precipitates of basic copper hydroxide & a solution of neutral salt sodium sulfate.

The components of a galaxy that exist in the space between the stars are: 4. Stars and planets.

A galaxy refers to a collection (group) of several billions of stars and interstellar matter, that are existing independently and by themselves in space. Thus, the largest (greatest) number of stars are found in a galaxy.

Based on astronomical records, the universal space comprises two (2) main components and these include the following:

In conclusion, we can deduce that the components of a galaxy that exist in the space between the stars are stars and planets because they are made up of two (2) interstellar hot gases, which include:

Answer:

It can affect it by taking away mass and volume. Mass and Volume are the two factors that calculate and make up density

Explanation:

Mass/Volume =Density

If you were to change the mass or volume by changing the size or shape of an object, then this would affect the density.

Answer:

Oxygen is in group 16 in the periodic table.  All the elements in this group have in common the number of valence electrons in their outer shell (6 valence electrons).  The only reason I can see that they may be considered "mixed"  is because the group includes non metals and metalloids.

Explanation:

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s

kinetic energy is given as

2) when speed is 3 m/s

kinetic energy is given as

3) when speed is 4 m/s

kinetic energy is given as

4) when speed is 5 m/s

kinetic energy is given as

5) when speed is 6 m/s

kinetic energy is given as

D) The mass of the reactant and products is equal and is not dependent on the physical state of the substances

Answer:

P is 5 ticks to the left of 0, so it would be -5/8

Q is 5 ticks to the right of 0, so it would be at 5/8

an absolute value turns a negative number into a positive number

so absolute value of  P located at -5/8 = 5/8

this is the location of point Q

Jimmy said that the absolute values of the numbers represented by the two points are the same.

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.

If an airborne pollutant is brought to the ground by rain or snow, it will be deposited closer to its source. This is due to the fact that the chemicals must be discharged nearby the source or captured in a cloud that would then transfer them.

Pollutants are substances which causes pollution to the atmosphere or hydrosphere. There are many types of airborne pollutants such as gaseous products from burning of fossil fuels.

Oxides of nitrogen and sulfur and some hydrocarbons  are the main airborne pollutants. They can be easily condensed because of the atmospheric humidity.

The deposition of these pollutants also depends on the wind, temperature and  diffusion rate of these gases. If the diffusion rate is less for the gas and the temperature is lower, they will deposit at the sources.
