How many moles of glucose are produced?



How many moles of oxygen are produced?

Answer:

645 g/mol

Explanation:

Step 1: Given data

Percent by mass of cobalt in cyanocobalamin: 4.34%

Step 2: Determine the molar mass of cyanocobalamin

There is one atom of cobalt in every molecule of cyanocobalamin, or what is the same, there is 1 mole of atoms of Co in every mole of molecules of cyanocobalamin. Given the molar mass of Co is 28.01 g/mol, the molar mass of cyanocobalamin is:

100 g B12/4.34 g Co × 28.01 g Co/1 mol Co × 1 mol Co/1 mol B12 = 645 g/mol

Answer:

Option 2: X is the screening constant, & it remains constant across a period.

Explanation:

I took the test and got the question correct :)

As we move across the period, X is the screening constant, and it remains constant across a period.

As we move across the period, the size of atoms become smaller because of an increase in the size of the nuclear charge. This leads to a decrease in atomic radius.

As the size of atom decreases, the screening effect on the outermost electron decreases accordingly. Hence, as we move across the period, X is the screening constant, and it remains constant across a period. This is because, no new shells are added across the period.

Explanation:

A pearlfish spends the day inside the alimentary tract, or intestines, of a sea cucumber. The fish emerges from the sea cucumber at night to feed on small crustaceans. The pearlfish gets a safe place to live. The sea cucumber does not gain anything from the relationship, nor is it harmed. This is similar to the relationship between bees and plants or sea anemonies and clownship and the correct option is option D.

Symbiosis is a close relationship between two species in which at least one species benefits.

For the other species, the relationship may be positive, negative, or neutral.

There are three basic types of symbiosis: mutualism, commensalism, and parasitism.

Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.

One species typically uses the other for a purpose other than food. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.

Therefore, a pearlfish spends the day inside the alimentary tract, or intestines, of a sea cucumber. The fish emerges from the sea cucumber at night to feed on small crustaceans. The pearlfish gets a safe place to live. The sea cucumber does not gain anything from the relationship, nor is it harmed. This is similar to the relationship between bees and plants or sea anemonies and clownship and the correct option is option D.

Answer:

a

Explanation:

The molecules of a substance formed a rigid repeating crystal structure. Then, a phase change occurred. That structure is now more like clusters of molecules moving past one another this change is caused by condensing phase.

The transformation of water vapor into liquid is known as condensation. The process is the opposite of evaporation, in which liquid water turns into a vapor. Either the air is chilled to its dew point or it gets too saturated with water vapor to retain any more water, causing condensation to occur.

By removing and transferring heat from the vapor to a cooling medium, condensation is the process by which a substance goes from its vapor phase to its liquid phase. The vapor must be saturated for the process to begin as well as having its vaporization heat reduced.

Thus, option A is correct.

Answer:

D

Explanation:

Gases have low densities. Density is the mass of an object divided by its volume. Mass of gases are quite small. Since the mass is related to mass of the particles itself. However the volume is great since the gases are far apart due to how weak the forces of attraction are ( gases take the shape of the container which means they take up a good bit of space which means greater volume). A small mass divided by a large volume gives a small value (small density).

Molar mass of KCl is M = (39.10 + 35.45) g/mol = 74,55 g/mol

amount of substance n = m/M = 45 g / 74.55 g/mol

Answer:

Answer: In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach ground at same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

Answer:

Explanation:

Na2O has 2 atoms of Sodium and 1 atom of Oxygen

So, the molecular mass of Na2O is:

(2 x Atomic weight of Na) + (1 x Atomic weight of O)

Atomic weight of Na = 22.99 g

Atomic weight of O = 16 g

Therefore, Molecular Mass of Na2O = (2x 22.99g) + (1 x 16g)

= (45.98 + 16)g = 61.98 g

Therefore 61.98 g of Na2O contains 6 x 10^23 molecules (Avogadro's number).

24.6 g of Na2O therefore contains:

(24.6/61.98) x 6 x 10^23 = Answer!

Answer:

Smashing the cube into pieces

Explanation:

The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.

The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.

The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.

It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.

The amount of reactants, the temperature, and the catalyst all influence the reaction rate.

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.

The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.

Thus, C is the correct answer.
