How does the skin help regulate body temperature?

HELP FAST

Answers

Answer 1

Answer:

Answer:

1. The body's immense blood supply (when blood vessels dilate or become larger heat loss occurs) When the blood vessels constrict it holds in heat

2. The skins blood supply also helps maintain body temperature (helps maintain homeostasis which is the "normal" state of our body)

3. Humidity in the air effects thermoregulation (heat regulation in the body) by limiting sweat evaporation (usually sweat evaporates into the environment when the humidity is low because the air has low "water levels" per say while you have high "water levels" because of your sweat

An ideal gas _____. does not exist
perfectly obeys all gas laws
only exists at very low temperatures
only exists at very high pressures

Answers

THE ANSWERS ARE A AND B!!!!

HOPE I HELPED

Answer:

does not exist

perfectly obeys all gas laws

Explanation:

Ideal gases is a simplification of real gases that is made to study them more easily. Then a hypothetical or theoretical, that is to say, imaginary gas is considered ideal gases. Despite not representing a gas that really exists, the ideal gas is a tool to facilitate a large number of mathematical calculations

The ideal gas behavior is at low pressures and high temperatures.

The ideal gas equation is based condensing Boyle's law, Gay-Lussac's, Charles's and Avogadro's law:

P * V = n * R * T

where:

P = pressure
V = volume
n = number of moles
R = universal gas constant
T = temperature

In this way an ideal gas perfectly obeys all gas laws.

What makes an atom able to form a compound? * O different number of neutron than protons O unfilled outer electron shells O same number of protons as electrons O a positive ot negative charge of the nucleus

Answers

Answer:

same number of protons as electrons

Explanation:

The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element. ... If you change the number of electrons in an atom, you will get an ion of the element.

Which reaction will most likely take place?Pt + FeCl3
Mn + CaO
Li + ZnCO3
Cu + 2KNO3

Answers

The correct answer of the given question above would be the third option: Li + ZnCO3. The reaction that will most likely take place is Li + ZnCO3. This is the reaction that will most likely take place since Lithium is very active. Hope this is the answer you are looking for.

I agree, the answer is Li+ZnCO3.

Which answer best describes the potential energy diagram for a reaction that takes place in water, if the temperature of the surrounding water is lowered? a. the potential energy of the reactants is low; the potential energy increases gradually; it peaks, then decreases slightly.

b.the potential energy of the reactants is high; the potential energy decreases gradually; then increases slightly.

c. the potential energy of the reactants is low; the potential energy remains low; rapidly peaks, then rapidly falls.

d. the potential energy of the reactants is low; the potential energy decreases gradually; then increases slightly.

Answers

Answer:

d. the potential energy of the reactants is low; the potential energy decreases gradually; then increases slightly.

Explanation:

Potential energy is the term that refers to the energy stored in a body, which can be used for several different things, even if transformed into other types of energy, depending on the need that that body presents at the moment. If the body needs to move, for example, the potential energy is transformed into kinetic energy. If the body needs to heat up or cool down, the potential energy turns into thermal energy.

Based on this, we can conclude what happens to the potential energy of a reaction that occurs in water, when the temperature of the surrounding water is reduced. If the temperature is reduced, it means that the water is losing energy and the potential energy of the reagents is low; as a result, the potential energy gradually decreases; then it increases a little.

d. the potential energy of the reactants is low; the potential energy decreases gradually; then increases slightly.

6Li + N2 2Li3NIf 12 mol of lithium were reacted with excess nitrogen gas, how many moles of lithium nitride would be produced?

4.0 mol
6.0 mol
12 mol
36 mol

Answers

Answer : The correct option is, 4.0 mole

Explanation : Given,

Moles of lithium = 12 mole

The given balanced chemical reaction is:

$6Li+N_2\rightarrow 2Li_3N$

By the stoichiometry we can say that, 6 moles of Li react with 1 mole of $N_2$ to give 2 moles of $Li_3N$

As, 6 moles of lithium react to give 2 moles of lithium nitride

So, 12 moles of lithium react to give $(12)/(6)* 2=4$ moles of lithium nitride

Therefore, the number of moles of lithium nitride produced will be 4.0 mole.

The answer would be B ur looking for the total reaction and the time that it takes for it I be produced Wich would be 6.0

Which compound contains a triple bond?

Answers

There are many compounds which contain triple bonds between two atoms. Few of the are as follow,

Nitrogen Molecule:

   N₂ or :N≡N:

Cyanide Ion:

  CN⁻ or [:C≡N:]⁻

Alkynes:
   R-C≡C-R

Carbon Monoxide:

CO or :C≡O:

Among given compounds Alkynes belong to a class of unsaturated hydrocarbons. The carbon atom in alkyne is sp hybridized. These unsaturated hydrocarbons have their own characteristic chemical properties.

Final answer:

A compound with a triple bond, like acetylene, is a molecule where three pairs of electrons are shared between two atoms. Acetylene contains a triple bond between its two carbon atoms. These bonds are strong, robust, and render unique properties to the compound.

Explanation:

A compound that contains a triple bond is a molecule in which three pairs of electrons are shared between two atoms, making it a very strong connection. An example of such a compound is acetylene (C2H2), which contains a triple bond between the two carbon atoms. The presence of triple bonds results in substances with unique properties when compared to compounds with only single or double bonds.

The triple bond in acetylene is formed by one sigma bond and two pi bonds. This means that acetylene is a more robust compound because of the strength of the triple bond. Additionally, molecules with triple bonds often have interesting chemical reactivities which make them important in various fields such as organic chemistry or industrial synthesis.
