Answer:
a structural formula
Explanation:
A structural formula simply shows the arrangement of atoms on a compound or molecule.
They are mostly used in representing hydrocarbons.
Through a structural formula we can give name to a compound.
For example, the compound given is called Propane, an aliphatic hydrocarbon with 3-carbon atoms.
The bond relationship connecting the species are also shown in this designation.
Answer:
1 mole of calcium contains 6.023 
atoms.
Explanation:
1 mole is the amount of a substance that contains exactly 
constituent particles. 1 mole of a substance is always equal to the atomic mass of the element.
Hence, 1 mole of calcium will also have atoms.
Number of atoms in 1 mole calcium = 6.023 atom
<span>Photons were the first sub-atomic particles detected, but not quite discovered as they could not be explained. Photons were first detected by Johann Wilhelm Ritter, Victor Schumann, and Winhelm Rontgen. The next, and first sub-atomic particle discovered, was the electron. The electron was discovered by J. J. Thompson in the late 1800s. The next two sub-atomic particle discoveries were the alpha particle and photon, discovered by Ernest Rutherford and Paul Villard respectively. Rutherford also discovered the proton and in 1932, James Chadwick discovered the neutron.</span>
Do a quick conversion: 1 grams Co2 = 0.0084841820909097 mole using the molecular weight calculator and the molar mass of Co2.
Answer:
547.7 g of C₆H₁₂O₆
Solution:
The balance chemical equation is as follow,
C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O
According to equation,
6 moles of O₂ burns = 180.56 g of C₆H₁₂O₆
So,
18.2 moles of O₂ will burn = X g of C₆H₁₂O₆
Solving for X,
X = (18.2 mol × 180.56 g) ÷ 6 mol
X = 547.7 g of C₆H₁₂O₆
