Answer:

i would test it and get real honey to see if the ingredients are the same

Explanation:

Explanation:

Water Test: In a glass of water, put a spoon of honey, if your honey is dissolving in water then it's impure. Pure honey has a thick texture that will settle at the bottom of a cup or a glass. –Vinegar Test: Mix a few drops of honey into vinegar water, if the mixture starts to foam, then your honey is impure.

The scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.

In 1927 German scientist Werner Heisenberg propounded the uncertainty principle which states that both the position and momentum of a particle cannot be measured simultaneously with certainty.

That is, the more accurate we measure the position of the particle, the less accurate we would measure its momentum.

Heisenberg's uncertainty principle is stated mathematically as ΔpΔx ≥ h/4π where p is the momentum, x is the position and h is Planck's constant.

So, the scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.

The source of gases for the secondary atmosphere of the earth was Volcanic Eruptions.

The scientist think that the atmosphere today is completely different from what it used to be originally and therefore they call it secondary atmosphere.

Internal volcanic activity or the deposit of debris from comet collisions produce a secondary atmosphere. 

The secondary atmosphere is thought to have formed as a result of the numerous volcanic eruptions that occurred from the start of Earth's early periods.

Although each volcano is unique, they all emit gases such as H₂O, CO₂, SO₂, H₂S, HCl, N₂, NO₂, and others.

These gases are formed due to melting of the Earth's crust.

Volcanic activity  renew the atmosphere's molecules.

These molecules are not the Nitrogen and Oxygen that make up the atmosphere today.

Answer:

more drought is not a global warming

Answer:

i think it is human migration

because when drought becomes more its one sign of global warming and when land becomes less there wont be place for people to plant trees

The atomic radius of Argon is smaller than the atomic radius of sodium because the effective nuclear charge increases as we move left to right in a period.

The atomic radius can be described as the shortest distance between the center of the nucleus of the atom and the outermost shell of the atom. An atomic radius can also be defined as half the distance between two atoms of the same element bonded together.

In general, the atomic radius of an atom reduces as we move from left to right in a period on the periodic table because while moving from left to right in a period, there is an increase in the effective nuclear charge. In periods, the valence electrons enter in the same outermost shell.

The atomic radius of atom increases when we move down a group because of the addition of a new principle shell.

Sodium is present at beginning of the third period and the Argon is present at the end of the same period. Therefore, Argon experiences a more effective nuclear charge than sodium so it has a smaller atomic radius.

When the cell potential is positive then the electrochemical reaction is spontaneous. The Ecell is positive when Zn serves as cathode and Mg serves as anode hence the reaction is spontaneous.

An electrochemical cell is any type of cell in which energy is produced by a spontaneous chemical reaction. Redox reactions that occur in an electrochemical cell produce energy.

An electrochemical cell becomes spontaneous only when Ecell is positive. Ecell is positive when a metal that has a more negative electrode potential serves as the anode.

Since Mg has a more negative electrode potential that Zn, it follows that a cell in which Mg is the anode and Zn is the cathode will have a positive Ecell and the reaction will be spontaneous.

Answer:

The lower the pressure, the lower a liquid's boiling point is. That's why water boils much faster at the top of a mountain than it does at the bottom. In space, there is no pressure. So the boiling point could easily drop to your body temperature.
