Geometry and bond angle of O atom in CH3OH
Bent; less than 109.5 degrees.
This physicist from New Zealand determine that atoms are mostly empty space with a small dense nucleus.
What is the most expensive metal on the periodic table?
Rhodium
This scientist was the first to recognize that the volume of a gas is inversely proportional to the pressure of a gas.
Robert Boyle
Who is credited with creating the modern periodic table?
Dmitri Mendeleev is credited with creating the modern periodic table by organizing the elements based on increasing atomic weight with periodic chemical properties.
What experimental technique is used to determine electron configuration?
PES
This physicist won the Nobel Prize in Physics in 1922 "for his services in the investigation of the structure of atoms and of the radiation emanating from them."
Niels Bohr
What is the only periodic table group that contains elements in three of the main states of matter at standard temperature and pressure?
Halogens
This scientist proposed that the volume of a gas is directly proportional to the temperature of a gas.
Jacques Charles
Shiny like silver, denser than lead, pricier than gold, could stop a bullet. What am I?
Osmium
Write the equation (including states) for the standard enthalpy of formation of potassium chloride.
K(s) + 1/2Cl2(g) --> KCl(s)
Who was the first person to win a Nobel Prize twice, and the only person to win a Nobel Prize in two scientific fields, chemistry and physics?
Marie Curie won the 1903 Nobel Prize in Physics for the discovery of radioactivity and the 1911 Nobel Prize in Chemistry for the "discovery of the elements radium and polonium, [the] isolation of radium and the study of the nature and compounds of this remarkable element."
Additionally, she was the first woman to win a Nobel Prize.
What is the most abundant element in the human body (by weight)?
oxygen
This element was commonly used as a prank among the nerdy chemists of the Victorian era. These chemists made spoons out of this element, which would then melt when their colleagues used the spoons to stir their tea.
gallium
Which isotope of uranium is used in nuclear chain reactions (fission)?
Uranium-235
Ethanol is miscible in water. What is a good method to separate the two substances?
Distillation
This ancient Greek philosopher was the first person to propose that matter is made of indivisible spheres.
Democritus
Which element is named after the most populous state in the USA?
Californium
This element was accidentally discovered by isolating it from over 1 ton of urine. Its flammable properties make it useful in matches.
phosphorus
Molybdenum
The Ksp of CaF2 is 4.3 x 10-11 in pure water. In acidic solution, the solubility of CaF2 is expected to (increase, decrease, remain the same) and why?
increase because the F- ion is basic.
This chemistry developed valence bond theory. and the idea of electron pairs to explain the shapes of molecules and chemical bonding. He never won a Nobel Prize, for which he was bitter. He was found dead in his Berkeley laboratory in 1946, where he had been working with hydrogen cyanide.
Gilbert Lewis
Which element is named after the most populous country in the EU?
Germanium
This scientist discovered cesium and rubidium. He also improved upon a commonly-used laboratory device, which was subsequently named after him.
Robert Bunsen
I am a planet, a God, and you use to me to measure temperature. What am I?
mercury
