6. An alloy of iron contains 75.0% iron and 25.0% other elements. How many grams of iron are present in 150. g of the alloy?

Answers

Answer 1

Answer:

108.5

Explanation:

half of 150 is 75 and half of that is 32.5. Add that to 75 and you'll get your answer

Answer 2

112.5 g of iron is present in the alloy.

From the question given above, the following data were obtained:

Percentage of iron (Fe) = 75%

Percentage of other elements = 25%

Mass of the alloy = 150 g

Mass of iron (Fe) =?

The mass of the iron present in the alloy can be obtained as follow:

[tex]Percentage = \frac{mass of element }{total mass }\\\\[/tex]

75% = [tex]\frac{mass of Fe}{150}[/tex]

[tex]0.75 = \frac{mass of Fe}{150}\\\\[/tex]

Cross multiply

Mass of Fe = 0.75 × 150

Mass of Fe = 112.5 g

Therefore, 112.5 g of iron is present in the alloy.

Answers

Answer:C.) It has one group in which the manipulated variable is tested, and another in which the responding variable is tested

Explanation: hope this helps

The statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested (option C).

What is a controlled experiment?

A controlled experiment is an experiment where one variable is tested at a time and all other variables are kept constant.

An experiment consists of a manipulated or independent variable, which is the variable changed, and a responding or dependent variable, which is the variable measured.

Therefore, statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested.

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.
