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.

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!

hello your question is incomplete attached below is the complete question

answer : attached below

Explanation:

The Lewis structure given in the question is incorrect attached below is the correct Lewis structure.

Lewis structure of a molecule is the representation of the valence electrons in a molecule

Answer:

The ball speeds up

Explanation:

“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.”

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

Explanation:

All explanations or thoughts led to that answer

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.

The noble gas configuration of vanadium (V), atomic number 23 will be [Ar] 3d34s2.

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].

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.

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.

Answer:The standard Gibbs energy change at 300K for the reaction 2A⇔B+C is 2494.

Explanation:

ΔG = free energy at any moment.

ΔGo = standard-state free energy.

R is the ideal gas constant = 8.314 J/mol-K.

T is the absolute temperature (Kelvin)

lnQ is natural logarithm of the reaction quotient
