Answer:
"ite"
Explanation:
Se sabe que los elementos del grupo 16 de la tabla prioritaria muestran estados de oxidación o valencias de 2,4 y 6 respectivamente, dependiendo del compuesto formado.
Por ejemplo, el azufre forma los siguientes compuestos;
sulfato de sodio (el azufre tiene una valencia de 6)
Sulfito de sodio (el azufre tiene una valencia de 4)
Sulfuro de sodio (el azufre tiene una valencia de 2)
Por lo tanto, en compuestos en los que exhiben una valencia de 4, la terminación común es "ite"

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).

Thanks.Hope it helps.write the conclusion of coin and feather experiment.
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.

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced. Manganese oxide was not used up in the reaction. Which of the following is likely to increase the rate of the reaction? (5 points)
Reducing the mass of the cube
Using a smaller amount of solution
Smashing the cube into pieces
Chilling the hydrogen peroxide solution
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.
What is the reaction rate?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.

Why do atoms become anion and cations (remember the octet rule and how 8 is a very important number)?
Answer:
The atoms become cations because they have lost electrons and the atoms and has a positive charge then atoms become a ions because they have gained electrons from cations and has a negative charge
A nucleus of uranium 235 decays. Its decay produces a nucleus of an unknown element (x), a nucleus of helium 4 and energy. What kind of radiation is produced by this decay?
Gamma beta or alpha?
Answer: Alpha
Explanation:
Alpha particle form of decay produces a nucleus similar to the element helium. During Alpha decay an atom spits out two protons and two neutrons from its nucleus.

How many moles is 45g of KCl?
Answer:
60.36
Explanation:
Answer: 0,60 mol
Explanation:
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

Vitamin B12, cyanocobalamin, is essential for human nutrition. It is concentrated in animal tissue but not in higher plants. Although nutritional requirements for the vitamin are quite low, people who abstain completely from animal products may develop a deficiency anemia. Cyanocobalamin is the form used in vitamin supplements. It contains 4.34% cobalt by mass. Calculate the molar mass of cyanocobalamin, assuming that there is one atom of cobalt in every molecule of cyanocobalamin. WebAssign will check your answer for the correct number of significant figures. g/mol
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
How many moles of glucose are produced?
How many moles of oxygen are produced?
Explanation:
5.00 mol H2O × (1 mol C6H12O6/6 mol H2O)
= 0.833 mol C6H12O6
5.00 mol H2O × (6 mol O2/6 mol H2O)
= 5.00 mol O2
