The molar mass of NH4NO3 in g/mol is 80g/mol.
HOW TO CALCULATE MOLAR MASS:
The molar mass of a compound can be calculated by summing the atomic masses of its constituent elements.
In ammonium nitrate (NH4NO3), there are nitrogen, hydrogen, and oxygen elements.
Atomic mass of nitrogen = 14Atomic mass of oxygen = 16Atomic mass of hydrogen = 1Molar mass of NH4NO3 = 14 + 1(4) + 14 + 16(3)
Molar mass of NH4NO3 = 80g/mol

What is the formula for this compound?
1 atom of copper, 1 atom of sulfur, 4 atoms of oxygen
Answer:
The third one: [tex]CuSO_4[/tex]
Explanation:
Again you are going to want to look at a periodic table so you can determine the symbol of each atom.
The symbol for copper is Cu, the symbol for sulfur is S and the symbol for Oxygen.
There is 1 atom of copper in the compound
So we have Cu
There is 1 atom of sulfur in the compound
So we would have CuS
There are 4 atoms of oxygen in the compound
So we would have [tex]CuSO_4[/tex]
Note that the little number at the bottom left after each symbol indicates how many atoms of that element are in that compound.

what is the Conversion of products into reactants
Answer:
In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can't change one element into another in a chemical reaction — that happens in nuclear reactions.
Explanation:
Explanation:
Thus, reactions in which products can be converted to reactant is called Reversible reaction.

The overall shape of a plant cell is most directly related to which of its parts?
Answer: Cell wall
Explanation: Cell wall is a unique structure found only in some specific organisms like plants, bacteria, fungi etc. The cell wall in plants is predominantly made up of a polysaccharide called CELLULOSE. This carbohydrate confers upon the cell "rigidity".
The cell wall is an additive material including the cell membrane that coats the external part of the cell of plants, hence, it gives plant cells their characteristic shape. The cell wall contributes to the overall flexible but rigid shape of the plant cell, protecting the cell against physical or chemical stresses.

Describe how a frog grows. Why do you think the eggs are found in the water? Where do you think fertilization happens?
The process of fertilization occurs externally in frogs.
Stages of lifecycleA full growth of frog occurs when it passes through five stages of its life cycle. During a frog's metamorphosis, an egg will hatch and a tadpole appear in which the back legs emerge first, then front legs, and finally it become a full grown adult frog.
Eggs of frogA frog's eggs are found in water because they do not have a hard protective shell like birds and reptiles. The frog's eggs are covered with a glycoprotein, which helps to keep the eggs moist so that's why the frog lays its eggs in water in order to prevent them from drying.
FertilizationIn most species of frogs, fertilization occurs externally. The male frog grabs the female's back and fertilizes the eggs as the female frog releases the eggs. Those eggs which receives the sperm will fertilized so we can conclude that the process of fertilization occurs externally in frogs.

Feather or bone when fall into food causing Physical contamination.
Food waste, like a feather or a bone etc fall into food causing Physical contamination because the contaminants such as feather and bone are mixed in the food physically not chemically. These contaminants can be removed through physical means such as with the help of hand.
Some contaminants mix with the food chemically means they react with the food and produce something new. Such type of contaminants are present in liquid form so we can conclude that feather or a bone etc when fall into food causing Physical contamination.

explain how wavelength is related to the energy of a wave
Answer: as the wavelength gets shorter, the energy increases; as the wavelength gets longer, the energy decreases. The greater the energy, the larger the frequency and the shorter (smaller) the wavelength.
Answer:
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.

Answer:
a difference in attitude
Explanation:
It's just not science. ... The big difference Popper identifies between science and pseudo-science is a difference in attitude. While a pseudo-science is set up to look for evidence that supports its claims, Popper says, a science is set up to challenge its claims and look for evidence that might prove it false.

Help me ASPAPPPPPPPPP
Answer:
Explanation:
1. H2O
Lewis Dot:
See the attachment.
Note the б+ and б- signs on the H and O atoms, respectively. Those represent the slightly positive and slightly negative sides of the water molecule. Those slight charges on a single water molecule are attracted to their opposite charges on neighboring H2O molecules, as shown in the graphic. This interaction is what gives water it's cohesive properties.
3. The property of cohesion describes the ability of water molecules to be attracted to other water molecules. which allows water to be a "sticky" liquid.
The hydrogen bonds are attractions of electrostatic force. They arise due to the difference in charge between the slightly positive hydrogen ion and the slightly negative oxygen ion. Hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond, and it is what gives water it's cohesiveness, or ability to support water spiders, paper clips, and produces a loud noise in the event of a belly flop in a pool (including the yelp from the swimmer).
4. I'm not sure what is being asked for the two blanks. Water is polar and dissolves salts (ionic compounds) and hydrophilic molecules (water-loving molecules).
