Sodium reacts with chlorine to form the compound sodium chloride, or salt. If the total mass of the reactants is 58.44 amu, what will be the total mass of the products?

Answer:

2H2 +O2 - 2H20

4g of H react to give 36g of H20

20g of H gives Xg of H20

cross multiply

4x= 36*20

4x= 720

Xg = 720/4

Xg= 180g approximately

That is A which is 179

The answer is 20.46g.

As we know that

1 mole of CO2 has 6.02 x 10^23 molecules of CO2.

Now, let's say x moles of CO2 has 2.80 x 10^23 molecules of CO2.

Therefore,

               x = 2.80 x 10^23 / 6.02 x 10^23 = 0.465

As, M = nmr

  M = 0.465 *( 12 + 2x16)

      = 0.465 *( 12 + 32)

      = 0.465 * 44

      = 20.46g

Answer: 4 ATP molecules is produced in the glycolysis of 2 glucose molecules

The first stage of most carbohydrate catabolism, which is described as the breakdown of larger molecules into smaller ones, is glycolysis, which is a part of cellular respiration. Two Greek words that mean "to break down anything sweet" are the source of the word glycolysis. Two molecules of ATP are created during the breakdown of glucose and formation of pyruvate during glycolysis.

The goal of the light reaction is to make NADH an high energy electron transporter and ATP an energy storing molecule.

The energy storage molecule ATP and the reduced electron carrier NADPH are produced by the light-dependent processes using light energy, which is required for the subsequent stage of photosynthesis. Light reactions in plants occur in the thylakoid membranes of organelles referred to as chloroplasts.

The light reactions are largely controlled by photosystems, sizable complexes of proteins and pigments (light-absorbing molecules) that are designed to capture light. Photosystem I (PSI) and Photosystem II are the two different types of photosystems (PSII).

Both photosystems have a variety of pigments that aid in the absorption of light energy as well as a unique pair of chlorophyll molecules at the reaction center. P700 denotes the special pair of photosystem I, while P600 denotes the unique pair of photosystem II.

If you perform a melting point test on a metal sample, you would expect to observe that the metal has a relatively high melting point compared to non-metallic materials. This is because of the strong electrostatic forces between the positive nuclei of the metal atoms and the negative electrons, which hold the metal atoms together in a tightly packed lattice structure. As a result, a large amount of energy is required to overcome these forces and melt the metal.

Metal samples are expected to be excellent conductors of heat and electricity when a conductivity test is performed on them. This is because electrons in metallic solids move through the metal fairly easily and are free to move around the lattice structure. This free movement of electrons allows heat and electricity to easily pass through the metal, making it highly conductive.

The density of chlorine will be  3.163 g/L.

The mass of a substance per unit of volume is its density. According to Graham's law, a gas's rate of effusion is inversely proportional to its square root density. When a material's particles are concentrated in a low area, they tend to travel to the place where the concentration is highest. When we use perfume or a scented spray in one area of the room and subsequently can smell it throughout the entire space, that is a simple illustration of this process.

rate1 = H2 = 5.93

rate2 = Cl2 = 1

The molecular weight of H2 = 2.016

The molecular weight of Cl2 = x.

By Graham's Law:

5.93 / 1 = x / 2.016

35.1649 = x / 2.016

x = 70.89 g/mol

The theoretical yield of water in this reaction is 1 mole (18.015 grams) of water.

Theoretical yield is the amount of a product one would expect to yield from a reaction if it proceeds to completion, according to a balanced chemical equation. It is calculated by multiplying the limiting reactant by the molar ratio between the reactants and the products. The actual yield of a reaction is usually lower than the theoretical yield, due to a number of factors such as incomplete conversion of reactants to products, product losses, and impurities in the reactants. Theoretical yield is used to calculate the percentage yield of a reaction, which is the ratio of the actual yield to the theoretical yield multiplied by 100.

The ocean current is caused by differences in water density. The difference in the density of water is mainly caused by the temperature and salinity of water.

Density of a substance is the measure of its mass per unit volume. It describes how closely its particles are packed within a given volume. Density of a substance is dependent on the temperature and pressure also.

The density of water is affected by the temperature and salinity. Water has its maximum density at 4 ° C. The more saline is water, more will be the density. Because, more ions or salts makes water denser.

The density vary with variations in temperature and salinity. This variation causes water currents from the denser areas to the less dense areas. Ocean currents are also affected by the gravity.

A gas law known as Gay-law Lussac's asserts that a gas's pressure (when kept at a constant volume and mass) varies directly with its absolute temperature

A gas law known as Gay-law Lussac's asserts that a gas's pressure (when kept at a constant volume and mass) varies directly with its absolute temperature. In other words, while the mass is fixed and the volume is constant, the pressure a gas exerts is proportional to the temperature of the gas.

In the year 1808, French scientist Joseph Gay-Lussac created this law. Gay-law Lussac's can be expressed mathematically as follows:

P ∝ T ; P/T = k

Where:

P is the pressure that the gas is applying.

T is the gas's actual temperature, while k is a fixed value.

The tire pressure of a car increases after driving. This is due to the air inside the tires heating up as a result of friction (a contact force) between the tires and the road. Gay-Law Lussac's states that because the air cannot expand because the tires are effectively fixed-volume containers, the pressure rises.

Explanation:

For i2+na2s2o3 titration,

I2 + 2 S2O3^-2 <--> 2 I^-1 + S4O6^-2

13.82 mL of 0.07203 M Na2S2O3 was needed to reach the starch indicator end point.

Number of moles of Na2S2O3 = 13.82*0.07203= 0.9954546 millimoles.

So, number of moles of excess I2 = 0.9954546/2 = 0.4977273 millimoles.

For oxidizing the ascorbic acid to dehydroascorbic acid

C6H8O6 + I2 --> C6H6O6 + 2 H+ + 2 I-

SO 1mole of I2 read for 1 mole of C6H8O6.

Initial I2 used = 50*0.01023 = 0.5115 millimoles.

Number of moles of I2 used = 0.5115 - 0.4977273 = 0.0137727 millimoles.

Number of moles of C6H8O6 in5 ml of orange juice = 0.0137727 millimoles.

Weight of C6H8O6 in5 ml of orange juice = number of moles * molecular weight = 0.0137727 * 176 = 2.4239952 mg

Give a succinct description of how the various alkene reactants were combined to create the same result. The most stable intermediate carbocation will arise as a result of an electrophilic proton addition in the reaction between HCl and both alkenes.

The observed product is produced in both cases by adding Cl- to the tertiary carbocation that is produced. By figuring out the physical properties of the reactants and products, negative entropy in chemical processes may also be calculated. Gas molecules are widely spaced apart and move randomly in all directions, which results in high entropy in gases. Being a liquid converting into a solid, water freezing into ice is an entropy-reducing process. Due to the molecules' reduced freedom of movement, a solid has less chaos.
