What is used to measure the energy in a chemical reaction?

Answers

Answer 1

I'm pretty sure it's a calorimeter.

Answer 2

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.

How does a balanced chemical equation prove the Law of Conservation of matter?

Answers

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

Answers

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 types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.

Identify the part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most and explain why this decrease occurs.

Answers

Answer:

Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.  as u know decreasing means going down and increasing means going up.  the reason why things decrease means something went wrong or something to happen to make it go down we all try to make things increase which means we try to make things go up instead of down. a lot of reasons is y things decrease is bc during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. for example like temperature when the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be ht or warm or maybe even cool. if something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased. sometimes decreasing could be a good thing but most of the time it it bad  but there are sometimes when decreasing is good but not all the time.

The part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most is from 1960 to 1970.

What the given graph shows?

Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.  As you know decreasing means going down and increasing means going up.  The reason why things decrease means something went wrong or something to happen to make it go down we all try to make things increase which means we try to make things go up instead of down. A lot of reasons is why things decrease is because during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. For example, Temperature. When the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be hot or warm or maybe even cool. If something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased.

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.

What is 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.

Evidence which claim about climate changeGreenland, Antarctica, and tropical mountain glaciers have all provided ice cores that illustrate how the Earth's climate responds to fluctuations in greenhouse gas levels. Tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks all contain ancient data.Yes, 97 percent of actively published climate scientists agree that people are to blame for global warming and climate change.Based on the data, nearly 97 percent of climate scientists agree that human-caused climate change is happening, according to the American Association for the Advancement of Science (AAAS).

Statue of Liberty - Is do to the sun which made the statue change color.

Bike rust - Is do to being exposed to moisture ( like Water, or any type or liquid.)

Hope this helps!!

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.

What is corrosion?

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.
