what happens at 100.0 degrees Celsius?
what happens from 100.0 degrees Celsius to 140.0 degrees Celsius?
Then solve the full problem, showing work & units.

Answer:

Every chemical equation follows to the law of conservation of mass, which states that matter cannot be created or destroyed. When you have an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced therefore it is following the law of conservation of mass.

Explanation:

Answer:

A balanced chemical proves the Law of Conservation of Matter because the law stats that matter cannot be created nor destroyed. so, in every chemical reaction the amount of matter will stay the same in the product as it did in the reactant.

In other words, balanced chem equations show that mass in conserved in chemical reactions

Answer:

Like magnetic poles repel each other

Explanation:

Among the following statements, the one that is true is Like magnetic poles repel each other.

Magnets are substances which possess their own magnetic field this magnetic field basically arises from the circular movement of negatively charge electrons. The elements which have unpaired electrons and have spin angular momentum or orbital angular momentum or they are together present are called as Magnets.

The magnetic field present is invisible but it is definitely responsible for the most notable property of a magnet. Magnetic force is a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

Therefore, Among the following statements, the one that is true is Like magnetic poles repel each other.

because the moon doesn't always go into earth's shadow

Answer:

It's true that the moon goes around Earth every month, but it doesn't always get in Earth's shadow. The moon's path around Earth is tilted compared to Earth's orbit around the sun. The moon can be behind Earth but still get hit by light from the sun. ... This is why we don't get a lunar eclipse every month.

I'm pretty sure it's a calorimeter.

Answer:

calorimeter

Explanation:

calorimeter

A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature.

Answer: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.

3. Manipulated: Trees with Leaves

Responding: Number of Bird Nests

4. Manipulated: Acid Rain

Responding: Fish Population

5. Manipulated: Calcium Given

Responding:  Bone Strength

Think about the manipulated variable as the changing item in the experiment. If this changes, the response will. (This is the Independent Variable)

Think of the Responding Variable as the result of the variable only can change when Manipulated is changed. (This is the Dependent Variable)

Hope This Helps :)

Manipulated variable in each case are watering of plants, number of chocolates, trees having leaves,water in acid rain, amount of calcium respectively and responding variables are growth  height, amount of homework,number of bird nests,fish population,bone strength.

Variables are defined as any characteristics, number or quantity which can be measured . It can also be called as a data item . It is called as variable because they can vary and can have variety of values.

There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variable  which do not change

Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

Genetically modified foods seem to be not as healthy as unmodified foods, according to research. also many people are against it due to the fact that some people go overboard and add too many genetically modified organisms, which causes health risks and unfortunately harms people. sometimes genetically modified food contains toxins and antibiotics. srry i couldnt find much on the process but this is based off my background knowledge so yeah

Answer:

a compound of the elements hydrogen, carbon, and oxygen. (also carbonic acid is a compound not a mixture ^-^)

Explanation:

hope this helps dude

According to the concept of solubility, carbonic acid is a mixture of water and carbon dioxide.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

A mixture of water and carbon dioxide under high temperature and pressure forms carbonic acid as it is highly soluble,thus carbonic acid is a mixture of water and carbon dioxide.

Both the situations are examples of corrosion. The green colour seen in statue of Liberty is due to the copper oxide formation whereas the resulting in bike parts is due to the formation of iron oxide in the surface.

Corrosion is a chemical process by which the metals are destroying and change in colour. Metal surface when open to air or water will react with the oxygen forms corresponding oxides.

Corrosion is an electrochemical process where the oxygen acts as the anode and the metal surface cathode where the oxide deposits and the colour changes. Materials containing iron will react with oxygen forms a red iron oxide called rust which then completely corrode the metal.

Similarly, the statues are made of metal alloys containing copper. Copper also reacts with air or water forms the copper oxide which is green in colour that is why the statues are turning to a gree patchy colour over time.

Answer:

There is solid proof that global warming is increasing and getting worse by t he day. The ice caps slowly melt more and more each year due to this which is a proven fact. On top of that, it has been proven that carbon emission by humans is bad for the environment and it helps increase the problem of global warming by weakening our atmosphere. As for the cold days, just because we have global warming doesn't mean the earth weather wont be cold. global warming is something that slowly happens and over time the temperature global has actually been increasing at a not very notice able pace.

Explanation:

Yes, climate is changing because of the human activities which are causing harm to the environment causing global warming.

Global warming is the long-term warming of Earth's climate system that has been seen from the pre-industrial period (between 1850 and 1900) as a result of human activity, principally fossil fuel combustion, which raises heat-trapping greenhouse gas levels in the atmosphere.

Answer:

Cleaning up oil spills and metal contaminates in a low-impact, sustainable and inexpensive manner remains a challenge for companies and governments globally.

But a group of researchers at UW–Madison is examining alternative materials that can be modified to absorb oil and chemicals. If further developed, the technology may offer a cheaper and “greener” method to absorb oil and heavy metals from water and other surfaces.

Aerogels, which are highly porous materials and the lightest solids in existence, are already used in a variety of applications, ranging from insulation and aerospace materials to thickening agents in paints. The aerogel prepared in Gong’s lab is made of cellulose nanofibrils (sustainable wood-based materials) and an environmentally friendly polymer. Furthermore, these cellulose-based aerogels are made using an environmentally friendly freeze-drying process without the use of organic solvents.

It’s the combination of this “greener"material and its high performance that got Gong’s attention.

“For this material, one unique property is that it has superior absorbing ability for organic solvents — up to nearly 100 times its own weight,” she says. “It also has strong absorbing ability for metal ions.”

Treating the cellulose-based aerogel with specific types of silane after it is made through the freeze-drying process is a key step that gives the aerogel its water-repelling and oil-absorbing properties.
