Answer:

In all living organisms, in substances like carbohydrate, starch, urea etc. To prove sugar contains carbon, take a little amount of sugar in spoon and heat it gently till it melts and turned into yellowish color. On further heating it changes into brown colored mass and then black, which is charcoal.

Take a small bit of sugar on a spoon and slowly heat it until it melts and turns a yellowish tint to demonstrate that it contains carbon. As it continues to heat up, it transforms into charcoal, which is a black mass first.

Strongly heating wood with little oxygen produces charcoal, a light black carbon residue that has been stripped of all water and volatile components.

Since the beginning of time, charcoal has been used for a wide variety of reasons, including art and healing, but its most significant usage has been as a metallurgical fuel. The typical fuel for a blacksmith's forge and other uses requiring high heat is charcoal.

Sugar breaks down into carbon and water when it is heated. Water is still a chemical, but it can't be heated

Thus,  As it continues to heat up, it transforms into charcoal, which is a black mass first.

Answer:

Answer: Hyperoxic alligators show significantly lower breathing rates than their siblings in normoxic and hypoxic groups. Conversely, each breath supports greater oxygen consumption in hyperoxic animals than in other groups. Statistical significance between groups was calculated by ANOVA with post hoc Tukey-Kramer

The explanation regarding the less atmospheric oxygen levels impacted the alligators growth should be because of Hyperbolic alligators.

There should be less breathing rate and the consumption of the oxygen should be high per breath.

The compensatory cardiopulmonary remodeling, the growth of the hypnotic alligators should be constrained by the less temperature with respect to the supply of the oxygen that should limited the food utilization capacity.

Answer:

the partial pressure of the O2 is 0.167 atm

Explanation:

The computation of the partial pressure of the O2 is shown below:

As we know that

P = P_N2 + P_O2 + P_CO2

P_O2 = P - P_N2 -  P_CO2

= (1.007 - 0.79 - 0.05)

= 0.167 atm

Hence, the partial pressure of the O2 is 0.167 atm

we simply applied the above formula

Answer:

In the middle of the forest.

Explanation:

They have to bury the remains in the middle of the forest at the Forensic Osteological Research Center in order to study the decomposition of the dead person. By studying the decomposition of dead person we can get a lot of information which can be used in the study of criminal cases and solving of crimes. The middle place in the forest is a perfect place to bury the remains due to presence of huge amount of microbes as well as insect that helps in the decomposition.

Answer:A modern statement is: Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Explanation:

The Avogadro's law is used here to determine the volume of the gas. Here the both samples have equal volume since they contain the same amount of gas.

The Avogadro's law states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules. Mathematically the law can be expressed as:

V ∝ n

The gases show great uniformity in their behaviour irrespective of their nature. Some useful generalisations have been deduced from the behaviour of gases which are known as gas laws.

The Avogadro's law follows that the volume of a gas is directly proportional to the number of molecules. But the number of molecules (N) of any gas is directly proportional to its number of moles (n).

So here if both samples contain the same amount of gas, both of them have the equal volumes. We cannot determine one with greater volume.

[tex]V_{base}=43.5cm^3[/tex]

Explanation:

Hello there!

In this case, given the neutralization chemical reaction of barium sulfate and nitric acid, it is possible to evidence the 1:2 mole ratio between them; thus, at the equivalence point we have:

[tex]2n_{base}=n_{acid}[/tex]

Which in terms of molarities and volumes is:

[tex]2M_{base}V_{base}=M_{acid}V_{acid}[/tex]

In such a way, by solving for the volume of base, we proceed as follows:

[tex]V_{base}=\frac{M_{acid}V_{acid}}{2M_{base}} \\\\V_{base}=\frac{45cm^3*0.29mol*dm^{-3}}{2*0.15mol*dm^{-3}} \\\\V_{base}=43.5cm^3[/tex]

A. Students made a measurement error, because ending with more products is impossible.

Explanation:

The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction. If there is excess mass in the product, the students have made an error of some kind.

Answer:

The Earth would become cooler until it probably attains a new equilibrium between absorbed solar energy and emitted solar energy.

Explanation:

The earth's energy balance refers to the balance between the energy absorbed from the sun (solar radiation) and the emitted (thermal) energy leaving the Earth. This balance ensures that the earth's surface temperature remains fairly constant.

When energy from the sun reaches the earth, it is absorbed and used by various features of the earth which uses it for their energy needs. Eventually, any excess radiant energy is sent back or emitted from the earth back into space such that the balance between absorbed and emitted energy is maintained.

However, if there is an imbalance whereby more energy is emitted than is absorbed, this would result in the earth losing more heat than it receives. This would result in the earth becoming more significantly colder until it probably attains a new equilibrium between absorbed solar energy and emitted solar energy.

Answer: c6h12o6+6o2→6co2+6h2o= C6H12O6 + 6O2 -> 6CO2 + 6H2O Yields 2755 kJ/mole of glucose. The reverse of this reaction – combing carbon dioxide and water to make sugar is known as photosynthesis. Photosynthesis is the process responsible for storing all the energy we extract from fossil fuels, crops, and all of our food. We will also see that it is part of a globally important cycle affected by our consumption of fossil fuels. Photosynthesis How is photosynthesis able to run the reaction above in the reverse direction? Somehow it must come up with 2755 kJ of energy to make each mole of glucose. Where does that energy come from? The short answer: photons of sunlight. The long answer: When the pigment chlorophyll inside the chloroplasts of a photosynthetic organism (phytoplankton, trees, other plants) absorbs sunlight, it becomes energetically ‘excited’ and grabs the hydrogen atoms away from a water molecule, leaving the oxygen atoms to escape as O2 gas. This is called ‘splitting water.’ The hydrogen atoms are then split into their component protons and electrons. The electrons are used to reduce carbon dioxide, in a series of many steps requiring more absorption of sunlight by chlorophyll, to glucose. When carbon dioxide receives those electrons, the extra negative charge attracts protons from elsewhere, creating hydrogen atoms attached to the carbon atom. This process is called reduction. When those reduced carbon dioxide molecules are combined together in a larger molecule, the result is glucose. This ‘combing together’ of small molecules requires an input of energy, which is provided by the ATP molecules made by the protons diffusing through the membrane of the chloroplast. The ATP molecule is simply a molecule that biology uses to store energy for later use. In this case, the mechanical energy created by the protons diffusing across the membrane turns a sort of molecular turbine that smashes together its precursors.
