A sample of acetic acid is composed of 2.05 g of carbon and 2.73 g of oxygen. Calculate the mass of carbon in another sample of acetic acid that is composed of 3.27 g of oxygen.
Which statement of Dalton's atomic theory corresponds to the law of multiple proportions?
Identify the statement that follows Dalton's atomic theory. Explain.
a. Water is formed when hydrogen and oxygen combine in a 1:2.5 ratio.
b. Copper can be made from iron atoms.
c. All atoms of zinc has the same mass and properties.
d. Carbon and nitrogen atoms have different physical properties but have identical chemical properties.
Methane (CH4) and ethylene (C2H2) are only composed of carbon and hydrogen. How much hydrogen would react with 1.78 g of carbon to produce methane and to produce ethylene? (Use the law of multiple proportions)
Given the following data:
Compound 1: 73.54% O and 26.46% N
Compound 2: 89.29% O and 10.71% N.
Demonstrate the law of multiple proportions by determining the formula of Compound 2 when Compound 1 is NO. (Compound 1 and 2 only contains nitrogen and oxygen)
A scientist in a parallel universe performs the Millikan oil-drop experiment. The unit of charge in that universe is gallic (ga). He obtained the following data for four oil droplets (A, B, C, and D):
A 2.06×10–11 ga
B 2.75×10–11 ga
C 4.13×10–11 ga
D 5.50×10–11 ga
Based on these observations, determine the charge on a single electron in ga units.
Identify the statement below that was derived from the results of the Milikan experiment using charged oil drops.
Determine which statement(s) is/are inconsistent with Rutherford's atomic theory.
a. An oxygen atom has 8 protons in its nucleus so there should be 8 electrons outside its nucleus.
b. Most of the mass of a chlorine atom is due to its 17 electrons.
c. Since protons are larger than electrons and a hydrogen atom only contains one proton and one electron, the volume of a hydrogen atom is mostly because of its proton.
d. A sulfur atom has 16 protons in its nucleus and 25 electrons outside of its nucleus.
