why does the tenpature change?
what are examples of natural production (not humans)?
what is the atomosephere?
PLEASE WRITE ONE PARAGRAPH FOR EACH QUESTIOIN
Answer:
why does the temperature change?
Daily air temperatures at Earth's surface are controlled by the incoming and outgoing energy. During the day, the air temperature increases as energy gains exceed the energy lost from Earth's surface. Throughout the night, the air temperature decreases as Earth's surface loses more energy than it receives.
What are examples of natural products?
Classes. The broadest definition of natural product is anything that is produced by life, and includes the likes of biotic materials (e.g. wood, silk), bio-based materials (e.g. bioplastics, cornstarch), bodily fluids (e.g. milk, plant exudates), and other natural materials (e.g. soil, coal).
What is the atmosphere?
The atmosphere is the blanket of gases which surrounds Earth. It is held near the surface of the planet by Earth's gravitational attraction.

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)
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

If one molecule of glucose (C6H12O6) reacts completely with three molecules of oxygen (O2) what is the TOTAL number of atoms that will be in the products
Answer:
30 atoms.
Explanation:
Based on law of conservation of proportion the atoms we have in reactants = atoms we have in products.
One molecule of glucose contains 6atoms of C, 12 atoms of H and 6 atoms of O, that is:
6+12+6 = 24 atoms
And 3 molecules of Oxygen are 6 atoms. The total atoms in reactants are:
24+6 = 30 atoms = atoms in products
Answer: It's 30 atoms.

Magnesium reacts with the oxygen in the air to form magnesium oxide. If 35 g of O2 was used in the reaction. How many Liters of O2 were present at 301K and a pressure of 1.35 atm?
Answer:
20.02 Liters
Explanation:
Mass = 35g
Volume = ?
Temperature = 301K
Pressure = 1.35 atm
The relationship between the quantities is given as;
PV = nRT
n = mass / Molar mass = 35 / 32 = 1.09375 mol
V = nRT / P
V = (1.09375 * 0.0821 * 301) / 1.35
V = 20.02 L

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.
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) =
5x10⁻³dm³Which subatomic particles have approximately the same mass?
protons and electrons
neutrons and electrons
protons and neutrons
electrons and atoms
Explanation:
protons and neutrons have approximately the same size, the electron is 1847th, (I think), the size of a proton
The subatomic particles which are having approximately the same mass are neutrons and protons. Thus, option c is correct.
What are subatomic particles?An atom is made of subatomic particles namely neutrons, protons and electrons. The neutrons and protons are located inside the nucleus whereas, the electrons are revolving around the nucleus through circular paths definite energy.
The electrons are having negative charges and protons are of positive charge. For a neutral atom the number of electrons and protons are equal. Electrons have negligible mass.
The mass of an atom is mainly contributed by the nucleus. The mass of neutrons and protons are have approximately same mass. Therefore, option c is correct.
