Mrs. Grogan wants to know if she is packing the same amount of animal crackers for her son’s snack each day.

She fills up a sandwich bag full of animal crackers each day. Mrs. Grogan takes the mass of the animal crackers and discovers that she uses 23.4 g, 25.2 g, 24.3g, 24.4 g, and 24.8 g of animal crackers for each day during the week. Convert the average mass into kilograms and record your answser to the correct number of significant figures. NO UNITS!

Answers

Answer: 0.02442 with 5 s.f. Explanation: (23.4g +25.2g +24.3g + 24.4g +24.8g)/5 = 24.42g. 1000g/kg so 24.42g = 0.02442 kg

i know that they are all pure substances but what else?

Answers

Answer :Matter makes up everything visible in the known universe, from porta-potties to supernovas. And because matter is never created or destroyed, it cycles through our world. Atoms that were in a dinosaur millions of years ago—and in a star billions of years before that—may be inside you today.     To form water, however, hydrogen and oxygen atoms must undergo chemical changes. For a chemical change to occur, atoms must either break bonds and/or form bonds. The addition or subtraction of matomic bonds changes the chemical properties of the substances involved. Both hydrogen and oxygen are diatomic—they exist naturally as bonded pairs (H2 and O2, respectively). In the right conditions, and with enough energy, these diatomic bonds will break and the atoms will join to form H2O (water). Chemists write out this chemical reaction as:

2H2 + O2 → 2H2O

This equation says that it takes two molecules of hydrogen and one molecule of oxygen to form two molecules of water. Notice that there are the same number of hydrogen atoms and oxygen atoms on either side of the equation. In chemical changes, just as in physical changes, matter is conserved. The difference in this case is that the substances before and after the change have different physical and chemical properties. Hydrogen and oxygen are gases at standard temperature and pressure, whereas water is a colorless, odorless liquid.  

Ecosystems have many chemical and physical changes happening all at once, and matter is conserved in each and every one—no exceptions. Consider a stream flowing through a canyon—how many chemical and physical changes are happening at any given moment?

First, let’s consider the water. For many canyon streams, the water comes from higher elevations and originates as snow. Of course that’s not where the water began—it’s been cycled all over the world since Earth first had water. But in the context of the canyon stream, it began in the mountains as snow. The snow must undergo a physical change—melting—to join the stream. As the liquid water flows through the canyon, it may evaporate (another physical change) into water vapor. Water gives a very clear example of how matter cycles through our world, frequently changing form but never disappearing.

Light energy allows these bonds to break and reform to produce sugar and oxygen, as shown in the chemical equation for photosynthesis:

6CO2 + 6H2O + light → C6H12O6 (sugar)+ 6O2  

This equation says that six carbon dioxide molecules combine with six water molecules to form one sugar molecule and six molecules of oxygen. If you added up all the carbon, hydrogen, and oxygen atoms on either side of the equation, the sums would be equal; matter is conserved in this chemical change.

When animals in and around the stream eat these plants, their bodies use the stored chemical energy to power their cells and move around. They use the nutrients in their food to grow and repair their bodies—the atoms for new cells must come from somewhere. Any food that enters an animal’s body must either leave its body or become part of it; no atoms are destroyed or created.

Matter is also conserved during physical and chemical changes in the rock cycle. As a stream carves deeper into a canyon, the rocks of the canyon floor don’t disappear. They’re eroded by the stream and carried off in small bits called sediments. These sediments may settle at the bottom of a lake or pond at the end of the stream, building up in layers over time. The weight of each additional layer compacts the layers beneath it, eventually adding so much pressure that new sedimentary rock forms. This is a physical change for the rock, but with the right conditions the rock may chemically change too. In either case, the matter in the rock is conserved.

The bottom line is: Matter cycles through the universe in many different forms. In any physical or chemical change, matter doesn’t appear or disappear. Atoms created in the stars (a very, very long time ago) make up every living and nonliving thing on Earth—even you. It’s impossible to know how far and through what forms your atoms traveled to make you. And it’s impossible to know where they will end up next.  This isn’t the whole story of matter, however, it’s the story of visible matter. Scientists have learned that about 25 percent of the universe’s mass consists of dark matter—matter that cannot be seen but can be detected through its gravitational effects. The exact nature of dark matter has yet to be determined. Another 70 percent of the universe is an even more mysterious component called dark energy, which acts counter to gravity. So “normal” matter makes up, at most, five percent of the universe.

how do I solve for V1 in this equation ​

Answers

Answer:

[tex]V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]

Explanation:

[tex]\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]

First of all cross multiply

That's

[tex]P_{1}V_{1}T_{2} = P_{2}V_{2}T_{1}[/tex]

Next divide both sides by [tex]P_{1}T_{2}[/tex]  in order to isolate [tex]V_{1}[/tex]

We have

[tex]\frac{P_{1}V_{1}T_{2}}{P_{1}T_{2}} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]

We have the final answer as

[tex]V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]

d. Keeping milk warm can help in slowing down of the reaction that can spoil milk.

Pasteurization can be defined as the heat treatment process in which the heat is provided to a liquid for example milk to prevent the growth of microbes which are least resistant to the heat. This process destroy the microbes, their spores, and also prevent their colonization.This process is useful in preventing soreness of milk and extends its shelf life. Keeping milk in cold container, in a cold temperature, or away from other sources of food will not help in slowing down the reactions that spoil milk.
