Answer:
Trail Mix
Explanation:
The best description for the snack that Ben is eating would be Trail Mix. This is a very common snack for hikers, hence the name, since it is very healthy and great for taking on hikes since it does not get affected by the sun. This snack was originally called GORP which stands for "good old raisins and peanuts" because the snack originally contained only raisins and peanuts.

A group of students collects data to determine whether compounds were ionic or covalent. They placed each compound in a small bowl and
stuck two open ends of a battery powered circuit in the compound
Answer:
The Answer is Yes, as all of these compounds are covalent since they are not conductive.
Explanation:
.
According to the concept of conduction, only ionic compound can conduct electricity that in aqueous state.
What is conduction?Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

Different solutions of salt X are made up. What volume of: a) a 4 mol/dm³ solution contains 2 moles of X? b) a 6 mol/dm³ solution contains 0.03 moles of X?
Answer:
a. 0.5dm³
b. 5x10⁻³dm³
Explanation:
a. A solution that is 4mol/dm³ contains 4 moles in 1dm³. The volume that contains 2 moles is:
2 moles * (1dm³ / 4mol) =
0.5dm³b. And for the 6 mol/dm³ containing 0.03moles:
0.03 moles * (1dm³ / 6mol) =
5x10⁻³dm³Fill in the blanks and name the process.

What do you already know about the structure of a water molecule?
Answer:
The key to understanding water's chemical behavior is its molecular structure. A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons
Explanation:

Explain how water is able to control fire.
Answer ASAP
Plzz
Answer: Fire requires oxygen to burn. Water "smothers" fire and prevents it from acquiring more oxygen. Fire also requires heat, which cool water may prevent/remove.
Answer:
See what happens is the water bender uses the water to control the fire by... jp lol
Explanation:
Real answer is the water puts out the fire because it is a non-combustible aqueous solution, therefore it's able to be used to control a fire.
Does the Sun or the Moon have a greater influence on the high and
low tides of Earth's bceans? Why?
Explanation: Because ocean tides are the effect of ocean water responding to a gravitational gradient, the moon plays a larger role in creating tides than does the sun. But the sun's gravitational gradient across the earth is significant and it does contribute to tides as well.

[tex]C_{25}H_{52}+38O_2\rightarrow 25CO_2+26H_2O[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.
The balanced chemical equation is:
[tex]C_{25}H_{52}+38O_2\rightarrow 25CO_2+26H_2O[/tex]
The given reaction is a combustion reaction as in a combustion reaction , a susstaance is oxidized in the presence of oxygen to give carbon dioxide and water.

1N2 + 3H2 -->2NH3
If you produced 34.06g of NH3 assuming excess N2 how many grams of H2 was used?
Answer:
grams H₂(g) = 6.11 grams H₂(g) used
Explanation:
Convert all given values to moles (if not already in moles), solve by rxn ratios and then convert moles to needed dimensions.
N₂(g) + 3H₂(g) => 2NH₃(g)
excess ? 34.6g/17g/mole = 2.04 moles
moles of H₂(g) needed = 3/2(2.04)moles = 3.05 moles H₂(g)
grams H₂(g) = 3.05 moles x 2 grams/mole = 6.11 grams H₂(g)

Why does air with higher amounts of water vapor have a lighter density?
Answer:
moist air is less dense than dry air because water has a lower molecular weight than nitrogen and oxygen
Answer:
Water vapor is a relatively light gas when compared to diatomic Oxygen and diatomic Nitrogen. Thus, when water vapor increases, the amount of Oxygen and Nitrogen decrease per unit volume and thus density decreases because mass is decreasing.
