Glucose contains hydrogen atoms from water or H₂O. Carbon dioxide and water are the reactants in the chemical reaction of photosynthesis. Oxygen and the carbon that glucose needs are both provided by carbon dioxide.
Because glucose cannot be further hydrolyzed, it is categorized as a monosaccharide. Due to its six-carbon structure and the presence of an aldehyde group on carbon 1, it is also categorized as an aldose and a hexose.
A glucose molecule is too large to pass through a cell membrane. cells assist glucose diffusion through facilitated diffusion and two types of active transport. This is evidence that the atoms that make up glucose have different properties than the molecule glucose.

Question 1
Given the equation: Q = mcAT
Q = heat (in Joules)
m = mass (in grams)
C = 4.18 (specific heat capacity)
AT change in temperature (°C)
How many Joules of heat energy are absorbed when 200 grams of water are heated from 20 C to 60 C.
Answers
The amount of heat energy absorbed when 200 grams of water are heated from 20 C to 60 C is 33,440 Joules.
To find the amount of heat energy absorbed when 200 grams of water are heated from 20 C to 60 C, we can use the equation Q = mcAT.
First, we need to find the value of m, which is the mass of the water in grams. In this case, it is given as 200 grams.
Next, we need to find the value of AT, which is the change in temperature in degrees Celsius.
This can be calculated by subtracting the initial temperature from the final temperature, which gives us 60 C - 20 C = 40 C.
The specific heat capacity of water, C, is given as 4.18 Joules per gram per degree Celsius.
Now we can plug in the values into the equation:
Q = mcAT
Q = (200 g) x (4.18 J/g°C) x (40°C)
Q = 33,440 J
Therefore, the amount of heat energy absorbed when 200 grams of water are heated from 20 C to 60 C is 33,440 Joules.

Answers
Answer:
0.05M is the concentration of the phosphate buffer
Explanation:
A buffer is defined as the aqueous mixture of a weak acid (KH₂PO₄) and its conjugate base (K₂HPO₄). The concentration of this buffer is the sum of the concentrations of the weak acid and the conjugate base, that is:
Concentration of phosphate buffer = 0.02M + 0.03M

When H2S(g) reacts with O2(g) to form H2O(g) and SO2(g), 124 kcal of energy are evolved for each mole of H2S(g) that reacts. Write a balanced equation for the reaction with an energy term in kcal as part of the equation.
Answers
Answer:
2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g) + 248kcal
Explanation:
The reaction of the problem occurs as follows:
H2S(g) + O2(g) → H2O(g) + SO2(g)
To balance the reaction we must balance oxygens:
H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g)
To balance the complete reaction:
2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g)
As the energy is evolved, 124kcal are as product in the reactio per mole of H2S. As the balanced reaction contains 2 moles of H2S, the heat evolved is:
124kcal*2 = 248kcal:
2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g) + 248kcal
And this is the balanced equation

When scientists say that a theory can never be proven, what are they actually saying?
Answers
When scientists say that a theory can never be proven, they mean that it is not possible to conclusively demonstrate its truth. The word "theory" in science refers to a body of knowledge that has been well-established through rigorous testing and observation. However, this does not mean that it is an absolute truth.
It is always subject to revision or even replacement when new evidence emerges or better explanations become available.The scientific method is based on the principle of verifiability, which means that theories must be tested in a way that allows them to be proven false. This is why scientists use experiments, observations, and other methods to test their theories. They look for evidence that supports the theory and also for evidence that contradicts it.If a theory withstands all the tests, it is considered well-supported by the available evidence. However, this does not mean that it is proven beyond a doubt. There is always a chance that new evidence may emerge that contradicts the theory, and this would require revision or replacement of the theory.In summary, scientists say that a theory can never be proven because scientific knowledge is always tentative and subject to revision. Theories can be well-supported by the available evidence, but they can never be proven beyond a doubt.For such more question on contradicts

what pressure would 1.75 L of disulfur monoxide gas have if it occupied a volume of 16.60 L at 1 atm?
Answers
Okay, let's solve this step-by-step:
* We are given that the initial volume of the gas is 1.75 L at 1 atm pressure
* We want to know the pressure if the volume increases to 16.60 L
* According to Boyle's Law: Pressure x Volume = Constant
* Since the initial pressure is 1 atm and volume is 1.75 L, the constant is:
1 atm x 1.75 L = 1.75 atm*L
* When the volume increases to 16.60 L, plugging into Boyle's Law:
P x 16.60 L = 1.75 atm*L
* Solving for P (pressure):
P = 1.75 atm*L / 16.60 L
P = 0.105 atm
Therefore, the pressure of the 1.75 L of disulfur monoxide gas if it occupied a volume of 16.60 L would be 0.105 atm.

Answers
The element with the electron configuration 1s22s22p63s23p64s23d104p2 is Silicon (Si).
Explanation:
The electron configuration of an element describes the arrangement of electrons in its atoms. The numbers and letters in the configuration represent the energy levels (n), sublevels (s, p, d, f), and the number of electrons in each sublevel.
In this case, the electron configuration of the element is:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p2
Breaking this down, we can see that the element has:
- 2 electrons in the 1s sublevel
- 2 electrons in the 2s sublevel
- 6 electrons in the 2p sublevel
- 2 electrons in the 3s sublevel
- 6 electrons in the 3p sublevel
- 2 electrons in the 4s sublevel
- 10 electrons in the 3d sublevel
- 2 electrons in the 4p sublevel
Based on the number of electrons in the outermost energy level (valence electrons), we can determine that this element is in group 14 of the periodic table. Looking at the periodic table, we can see that the

Calculate the volume (in mL) of 6.0 M NaOH solution required to prepare 1.0 L of 0.09000 N NaOH solu
Answers
Answer:
the volume in mL is 15
Explanation:
The computation of the volume in mL is shown below:
As we know that
N = nM
where
N denotes the normality
n denotes the number of equivalents
M denotes the molarity
Also
For NaOH , N = M
Now
M× V_1 = N × V_2
V_1 = N × V_2 ÷ M
= 0.09000 N × 1.0 L ÷ 6.0 M
= 15 mL
hence, the volume in mL is 15
(b) Two compounds, A and B, have the molecular formula C₂H6O. On treatment with Na metal, compound A releases H2 gas and compound B does not.
Can you give a reason to help to explain the observation better?
Answers
The observation that compound A releases H2 gas while compound B does not when treated with Na metal can be explained by considering the structural differences between the two compounds and their ability to undergo specific reactions.
Compound A and compound B both have the molecular formula C₂H₆O, which indicates that they both contain two carbon atoms, six hydrogen atoms, and one oxygen atom. However, the difference lies in the arrangement of these atoms within the molecules. One possible explanation for the observed difference is that compound A is an alcohol, specifically ethanol (CH₃CH₂OH), while compound B is an ether, such as dimethyl ether (CH₃OCH₃). The presence of the hydroxyl group (-OH) in ethanol enables it to undergo a reaction with sodium metal, known as the metal-acid reaction. In this reaction, the metal displaces the hydrogen from the hydroxyl group, forming sodium ethoxide (CH₃CH₂ONa) and releasing hydrogen gas (H₂). On the other hand, ethers like dimethyl ether lack the hydroxyl group and therefore cannot undergo the metal-acid reaction. Consequently, when compound B is treated with sodium metal, no hydrogen gas is released. The ability of compound A to release hydrogen gas while compound B does not when treated with sodium metal can be attributed to the presence of a hydroxyl group in compound A (ethanol), enabling it to undergo a metal-acid reaction, whereas compound B (dimethyl ether) lacks the necessary functional group and thus does not undergo this reaction.
