What volume, in liters, does 128 grams of O2 occupy at STP?
89.6 L
22.4 L
67.2 L
44.8 L

Answers

Answer: 89.7 L

Explanation:

89.6 volume, in liters, does 128 grams of O2 occupy at STP. Therefore, option A is correct.

What do you mean by volume ?

A volume is simply the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids. Volumes differ depending on the shape.

Every three-dimensional object requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object within the boundaries of three-dimensional space. It is also known as the object's capacity.

1 mole Oxygen has mass 32 grams

Mole of Oxygen in 128 g mass = 128 g / 32 g/mol

= 4.0 mol O2

At Standard temperature and pressure this has volume

= 4.0 mol × 22.4 L/mol

= 89.6 L

Thus, 89.6 volume, in liters, does 128 grams of O2 occupy at STP, option A is correct.

Cobalt(II)chloride is commonly obtained from chemical supply houses as a hydrate with the formula CoCl2.6H2O. An analysis showed that 25.0g of this hydrate contains 11.3g of water. What us the present water by weight in this hydrate?

Answers

Answer:

The present water by weight for the hydrate = 45.2%

Explanation:

From the given information;

The present water by weight = (weight of the water/ total weight of the hydrate) × 100

The present water by weight = (11.3/25) × 100%

The present water by weight = 0.452 × 100%

The present water by weight for the hydrate = 45.2%

6. What does a numerical subscript following a set of parentheses in a chemical
formula mean?

Answers

It is similar to the subscript next to an element, it indicates how many of the group or polyatomic ion in parentheses are present in the formula.

As an example, calcium hydroxide is Ca(OH)2 The subscript indicates that this formula contains two hydroxide ions.

A numerical subscript following a set of parentheses represents the number of the group or poly-atomic ion in parentheses are present in a chemical  formula.

As an example, calcium hydroxide is [tex]\bold { Ca(OH)_2 }[/tex] . The subscript (2) indicates that calcium hydroxide contains two hydroxide ions.

An equimolar mixture of X (g) and Y (g) is placed inside a rigid container at constant temperature. The particle diagram above represents the changes that occur over time. Based on the particle
diagram, which of the following best predicts whether or not the system has reached equilibrium by 300 s?
a. It is not possible to determine that the system has reached equilibrium by 300 s because the stoichiometry of the reaction is not known.

b. it is not possible to determine that the system has reached equilibrium by 300 s because the amounts of X, Y, and XY have continued to change

c. The system has reached equilibrium by 300 s because the rate of formation of XY is constant
d. The system has reached equilibrium by 300 s because the rates of consumption of X and Y are equal

Answers

Answer:

B

Explanation:

t= 300s has more XY than t=200s, which means that it continues to change

*i think

The system has been predicted to be not possible to reach equilibrium as  changing X and Y concentration. Thus, option B is correct.

Equilibrium has been described as the condition in the reaction mixture, when the concentration of the product and the reactant are equal.

The given reaction has been represented as:

[tex]\rm X+Y\rightarrow\;XY[/tex]

Reaction mixture at 300 s

The given reaction has been represented as, with the increase in time, there has been the consumption of the reactant and the formation of product.

The concentration has been continuously changing with time. Thus, the determination of the equilibrium has been difficult with changing X and Y concentration.

Thus, option B is correct.

Explain the trend in boiling points as you move down group v11

Answers

Answer:

Fluorine    

Chlorine

Bromine

Iodine

Boiling point increases as you go down the group v11

Explanation:

The elements of Group VII  are the halogens consisting of f fluorine (F), chlorine (Cl), bromine (Br), iodine (I).  All of which are non metals and exists  as diatomic molecules - F2, Cl2, Br2, I2 with  intermolecular attractions between the two molecules of each element held by Van der Waals dispersion force.

Moving down the group, the size of the atoms increases in size from Fluorine, F2 and Chlorine, Cl2 which are gases to Bromine , Br2 which exists as a liquid to solid, Iodine, I2. This attributes to the increasing in Strength of the Van der Waals forces as you go down the group. In order to break the vanderwaals forces , More heat energy is required to change thier states  leading to the increase in  boiling point going down the group.

What is air?

The term "air" is used to refer generally to the concoction of gases that composes the Earth's atmosphere. Nitrogen makes up the majority of this gas (78%), with oxygen, water vapor, argon, carbon dioxide, and trace gases also present.

There is no color or smell in pure air. Dust, pollen, and spores are common airborne contaminants; additional pollutants are alluded to as "air pollution." Since there isn't air in space, the so-called air on another planet, like Mars, would have different manufacturer. Warm and cold air fronts with points labeled 1 through 4, cold air entering from the left and moving down.

Therefore, the correct option is option 1.
