if I have a +2 oxidation number do I give up or accept electrons?
Answers
Answer:
I will give up the electrons
Explanation:
Consider the following rules:
1. An atom loses electrons if its oxidation number is positive.
2. An atom gains electrons if its oxidation number is negative.
3. An atom neither gains nor loses electrons if its atomic number is zero.
As I have an oxidation number [tex]+2[/tex] that is oxidation number is positive, so, I will give up electrons.

Which of the following has the smallest atomic radius?
a B
b Al
c F
d N
e Ga
Answers
Answer:
c. F
Explanation:
As you go top to bottom down a column of the periodic table, atomic radius increases.
As you go left to right across a period of the periodic table, atomic radius decreases.
Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

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.
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.

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.
Fluorine
Chlorine
Bromine
Iodine

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 sThe 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.

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%
