Answer:

She should change the temperature of the water.She should measure the amount of jaggery that dissolves.

Explanation:

It's important to note that all of the variables listed could potentially affect the amount of jaggery that dissolves in water. However, in order to investigate the effect of water temperature on the amount of jaggery that dissolves, she should hold all other variables constant (such as the volume of water, size of jaggery, and texture of jaggery) and only vary the temperature of the water.

- By doing this, she can isolate the effect of water temperature on the amount of jaggery that dissolves and draw conclusions about the relationship between these two variables.

What is NMR spectroscopy?

NMR (nuclear magnetic resonance) spectroscopy is a well-known technique in organic chemistry which is used to determine the structure of the organic compound. It works on the principle in the presence of an external magnetic field some nuclei which have spin are transferred from lower energy level to higher energy.

The double bond equivalence/ degree of unsaturation gives an idea about the number of double bonds or rings present. It can be calculated as:

DBE = C - H/2 - N/2 + 1

Here, C, H and N is number of carbon, hydrogen and nitrogen atom respectively. Determination of the DBE, gives us a preliminary idea about the structure.

By substituting the value of C, H and N as 5,10 and 0 in equation (1), we calculate the Double bond equivalence as:

DBE = 5 - 10/2 - 0/2 +1

DBE = 1

The peak obtained at δ1.1 for 9H indicates the presence of 9 equivalent hydrogen atoms which are saturated. The peak obtained for a single H at

At the end of glycolysis, one can find the energy that was contained in the chemical bonds of glucose in ATP, NADH and pyruvate molecule.

The process of glycolysis takes place in the cytosol of a cell. It can be broken down into two phases viz. energy requiring phase and energy releasing phase.

Energy requiring phase: The starting molecule i.e glucose is at first rearranged and two phosphate groups are attatched to it, which comes from ATP.  The phosphate groups form the sugar- fructose-1,6-biphosphate. This splits into three-carbon sugars

Energy releasing phase: The three carbon-sugars are converted into three-carbon molecules i.e two ATP molecules and one NADH molecule and pyruvate.

Temperature, pH, PCO2, and 2,3 diphosphoglycerate are some of the variables that affect how oxygen binds to hemoglobin.

The oxygen dissociation curve moves to the right and Hb's affinity for O2 decreases as its temperature rises. The oxygen Hb dissociation curve changes to the right as the partial pressure of carbon dioxide rises, increasing the P50 value. As a result of greater Hb binding to carbon dioxide, Hb has a lower affinity for oxygen.

High pO2: The more oxygen there is in the air, the more effectively haemoglobin binds to oxygen.Low pCO2: Oxyhemoglobin production is reduced by a lot of carbon dioxide. Compared to oxygen, carbon dioxide has a stronger affinity for hemoglobin.Less H+: Hemoglobin is more likely to dissociate when the pH is lower or the hydrogen ion concentration is higher.Lower temperature: Hemoglobin and oxygen are more likely to bind at a normal temperature.

The equation you provided is an example of a chemical reaction in which nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia (NH3). The Law of Conservation of Mass states that matter cannot be created or destroyed, only transformed from one form to another.

In this reaction, the total number of atoms on the reactant side (left side of the arrow) is equal to the total number of atoms on the product side (right side of the arrow). Specifically, there are 2 nitrogen atoms, 6 hydrogen atoms, and 2 ammonia molecules on the reactant side, and these atoms are rearranged to form 2 nitrogen atoms, 6 hydrogen atoms, and 2 ammonia molecules on the product side.

This demonstrates that the total mass of the reactants is equal to the total mass of the products, which is a key principle of the Law of Conservation of Mass.

Mass of Zn produced in iron nail= 0.630g -0. 610g = 0.01g

Mass of Zn consumed = 5.720 to 5.710 g = 0.01g

Given length of time run= 5 min = 5× 60 = 300 second

Moles of Zn passed = 0.001g = 0.00015 mol

1 mol contain = 6.022×10^23 atoms

Total electron contain in 0.00015 mol of Zn atoms

An O—O ligand fragment and a C atom serve as the foundation of the carbon dioxide MO diagram. The O—O fragment and carbon both have 2S and 2Px, y, z orbitals, which are involved in the creation of molecular orbitals.

What exactly is the O2 molecular orbital diagram?

Because of this, O2's electronic configuration is as follows: O2:KK(σ2s) 2(σ2s∙) 2(π2px)2=(π2py)2(π2px)1=(π2py∙) 1. The oxygen molecule's molecular orbital energy level diagram is shown as follows: Bonding sequence 2NbNa=284=2. Consequently, the oxygen molecule has two bonds.

The average atomic mass of Michelle's sample is equal to 53.549 amu.

What is the natural abundance of elements?

Natural abundance can be defined as the abundance of natural isotopes of a chemical element found on a planet. The relative atomic mass can be defined as the atomic weight of the element in the periodic table.

The natural abundance of an isotope is affected by the probability of its creation and by the production of an isotope as a daughter of the natural radioactive isotope.

The mass of one isotope = 56.2925 amu, relative abundance =28.49%

The relative abundance of the other isotope = 100 - 28.49 = 71.51 %

The mass of the other isotope = 52.4566 amu

Average atomic mass  = 56.2925 × 0.2849 + 52.4566 × 0.7151

Average atomic mass = 16.0377 + 37.511

Average atomic mass  = 53.549 amu
