1 mole of any gas is equivalent to?
Answer:
22.4 L at standard temperature and pressure.
For the balanced equation shown below, how many moles of H2O will react with 9 moles of N2?
N2 + 4H2O --> 2H2O2 + N2H4
Answer:
36 mole of H20
Explanation:
N2 + 4H2O --> 2H2O2 + N2H4
H20 : N2
4 : 1
x : 9
cross multiplication
so,
= 9x4/1 = 36 mole of H20

What is a fault, and how does the existence of faults support the theory of plate tectonics?
“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”
(Wesson, 1972)
Why is there a hole in the ozone layer? What do you think the consequences of that hole are?
Answer:
There is a ozone layer because of the special atomphere and chemical conditions that takes place there. I think the consequences of that home area is the very low winter temperatures.
Answer:
There is a hole in the ozone layer because of the pollution on earth. Because of that the UV rays are easily entering the earth through that portion. The consequences of this can be cancers, global warming and disastrous storms.

before you retire in the evening, you sit down for a snack of milk and cookies. when you waken in the morning, you discover a carton of sour milk on the counter. knowing that milk sours if left in the refrigerator too long, has the reaction rate increased or decreased for the carton of milk on the counter? what has happened to its reaction time
Answer:
Increased
Explanation:
We know that the higher the temperature the higher the rate of reaction. This implies that as the temperature is increased, a reaction tends to proceed faster.
This follows from the collision theory, the higher the temperature, the higher the energy of the reacting particles hence they collide with each other faster and more effectively.
Thus the rate of reaction( or reaction time) for the carton of milk on the counter was increased.

Give the noble gas configuration of vanadium (V), atomic number 23
The noble gas configuration of vanadium (V), atomic number 23 will be [Ar] 3d34s2.
What is noble gas configuration ?The electron configuration of noble gases would be known as that of the noble gas configuration. The propensity of chemical elements to gain stability forms the foundation of all chemical reactions. Chemical formation frequently leads to an entire electronic configuration approximating a noble gas for several main group elements.
The atomic number of V = 23
The noble gas configuration = [Ar] [tex]3d^{3} 4s^{2}[/tex].

Explain the meaning of thermal energy transfer and give specific examples of conduction, convection, and radiation.
Answer:
thermal energy: the part of total internal energy that can be transferred (a portion of the kinetic energy)
heat is the thermal energy that flows from one substance to another due to a temperature difference.
Thermal energy is measured in temperature change.
Thermal energy transfer stops when thermal equilibrium is achieved (Both substances at the same temperature).
conduction: Transfer of thermal energy through a solid object like heat transferring up a metal spoon from a hot cup of coffee.
convection: the transfer of thermal energy due to the movement of a liquid or gas caused by differences in temperature. Only in a fluid (liquid or gas). Breezes, ocean currents.
radiation: Transfer energy with or without matter. Warming from the Sun, microwave oven.
Answer:
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission. Hope this helps!

Organisms are classified into different kingdoms based on?...
Answer:
Food and cell type
Explanation:
Kingdoms are by far the most basic legal structure for living objects. Living objects are classified into realms depending on how they consume food, the kinds of cells that produce their bodies, and the total type of tissue in their bodies.
1 In what type orbital are the outer electrons of the atoms of the elements of Group 1 (IA) and Group 2 (IIA)?
Answer:
s orbital
Explanation:
The elements of Group 1 (IA) and Group 2 (IIA) have one and two electrons in their outermost shells respectively.
For the elements in group Group 1 (IA), the general outer electron configuration is ns1. This last electron is accommodated within an s orbital.
For the elements in Group 2 (IIA), the two outermost electrons are accommodated in an ns orbital, hence the answer.
True or False. Chemical changes only rearrange the elements that are
already present.
True or False. The reactants and the products of a chemical equation
always have the same number of atoms.
