True or False: If you find the percent by mass of all of the elements in a compound, it will always add up to exactly 100.00%
Answers
Answer: true
Explanation: because Mass percentage composition is found by calculating a fraction of the total mass by each element present in a compound. The whole compound itself would equal one or 100% in all the elements that make it up would only be a fraction, so it will always have to add up to 100%

How many moles of carbon are there in 5 g of carbon?
Answers
Answer:
0.416666667
Explanation:
number of moles= mass of sample ÷ molar mass
=5÷12
=0.41666667
The number of moles of carbon are there in 5 gram of carbon is 0.41 moles.
How do we calculate moles from mass?Moles of any substance will be calculated by using the mass by following the below equation:
n = W/M, where
W = given mass of carbon = 5g
M = molar mass of carbon = 12g/mol
On putting values, we get
n = 5 / 12 = 0.41 moles
Hence required moles of carbon is 0.41 moles.

how to name iupac compounds
Answers
Answer:
In order to name organic compounds you must first memorize a few basic names. These names are listed within the discussion of naming alkanes. In general, the base part of the name reflects the number of carbons in what you have assigned to be the parent chain. The suffix of the name reflects the type(s) of functional group(s) present on (or within) the parent chain. Other groups which are attached to the parent chain are called substituents.

What must occur in order for matter to change states?
A.
A chemical change must occur.
В.
The temperature must change.
C. Heat must be added or removed.
D.
Other substances must be added.
Answers
Answer:
C. Heat must be added or removed
Explanation:
When matter changes states it is due to the overall loss or gain of heat. In addition, heat being added or removed is what will cause a temperature change, but a simple temperature change is not enough to change states. For example, a temperature could go from 50 degrees to 51. This will not cause a change in states. So heat must be added or removed in order for matter to change states.

Nitroglycerin contains 60% as many carbon atoms as hydrogen atoms, three times as many oxygen atoms as nitrogen atoms, and the same number of carbon and nitrogen atoms. The number of moles in 1.00g of nitroglycerin is 0.00441. What is the molecular formula?
Answers
Answer:
C₃H₅N₃O₉
Explanation:
Molar mass of nitroglycerin (Ratio of mass and moles of the compound) is:
1.00g / 0.0041mol = 226.8g/mol
We can write the equations:
0.6H = C (1)
-60% as many carbon atoms as hydrogen atoms-
3N = O (2)
C = N
Using as basis the atoms of Carbon:
Carbon = 1
Nitrogen = 1
Oxygen = 3
Hydrogen = 1/0.6 = 1.67
A molecular formula has just whole numbers. This ratio of atoms times 3:
Carbon = 3
Nitrogen = 3
Oxygen = 9
Hydrogen = 5
C₃H₅N₃O₉. Molar mass of this formula is:
C = 12.01g/mol*3 = 36.03g/mol
H = 1.01g/mol*5 = 5.05g/mol
N = 14g/mol*3 = 42g/mol
O = 16g/mol*9 = 144g/mol
Molar mass:
36.03g/mol + 5.05g/mol + 42g/mol + 144g/mol = 227g/mol ≈ 226.8g/mol
That means molecular formula of nitroglycerin is:
C₃H₅N₃O₉The molecular formula of nitroglycerin is C₃H₅O₉N₃
Mass of nitroglycerin = 1.00 g
A number of moles of nitroglycerin = 0.0041 mol
It is required to calculate the molecular formula of nitroglycerin.
What is the empirical formula?An empirical formula tells us the relative ratios of different atoms in a compound.
The molecular formula of nitroglycerin can be estimated with the help of empirical formula.
The molar mass of nitroglycerin (Ratio of mass and moles of the compound) is:
1.00g / 0.0041mol = 226.8 g/mol
We can write the equations:

C = N
Using as basis the atoms of Carbon:
Carbon = 1

A molecular formula has just whole numbers. This ratio of atoms times 3:

C₃H₅N₃O₉.
Molar mass of this formula is:
C = 12.01g/mol*3 = 36.03g/mol
H = 1.01g/mol*5 = 5.05g/mol
N = 14g/mol*3 = 42g/mol
O = 16g/mol*9 = 144g/mol
Molar mass:
36.03g/mol + 5.05g/mol + 42g/mol + 144g/mol = 227g/mol ≈ 226.8g/mol
That means molecular formula of nitroglycerin is:

What describes the light as electromagnetic waves?Light as a wave: Light is a type of electromagnetic wave that can be represented mathematically (described). A shifting magnetic field is produced by a shifting electric field, according to this paradigm. Light is produced when the electric field changes as a result of the changing magnetic field.Light can be thought of as a wave. Light is a type of electromagnetic wave. A fluctuating electric field, according to this hypothesis, generates a fluctuating magnetic field. The interaction of a changing magnetic field with a changing electric field produces light. When charged particles, such as electrons and protons, move, they generate electromagnetic fields, which transport the type of energy known as electromagnetic radiation, or light.To Learn more About electromagnetic radiation, Refer:

How do magnetic stripes show the history of Earth's magnetic field?
A. As you move away from an ocean ridge, the rocks get older.
B. As you move away from a coast, the rocks get younger.
C. As you move down through the seafloor, rocks get older.
D. As you move eastward along a continent, rocks get older.
Answers
The way that magnetic stripes show the history of the Earth's magnetic field is A. As you move away from an ocean ridge, the rocks get older.
What do magnetic strips show of Earth's history ?By looking at how our planet's magnetic field changes throughout time, scientists may estimate the age of the seafloor. A geomagnetic reversal is the periodic reversal of the currents in the liquid core that generate the Earth's magnetic field. Throughout Earth's history, this has occurred frequently.
When researchers examined the seafloor's magnetic characteristics, they found normal and reversed magnetic stripes of varying widths. These magnetic patterns are symmetrical on both sides and parallel to the mid-ocean ridges.
Away from midocean ridges, they observed that the age of the bottom became progressively older.
