In which reaction do four total molecules of reactants produce two total molecules of products? 2SO2 + O2→2SO3 2H2S + 3O2→2SO2 + 2H2O SnO2+ 2H2→Sn + 2H2O N2+3H2→2NH3

750. ml of water was almost boiled to 87.0°C then placed on the counter to cool until it reached 22.0. How much heat did the water lose? (specific heat of water = 4.184J/g C)

What is the oxidation state Ca (NO3) 2

The mass of a single molybdenum atom is 1.59*10-22 grams. How many molybdenum atoms would there be in 40.6 milligrams of molybdenum?

The sedimentary rock formed when water deposits tiny particles of clay in very thin flat layers is called? a. gymsum b. shale c. limestone d. calcite

What change into velocity

Would you expect the h atoms to remain bonded to each other, or would the molecule fall apart?

Conductivity in a metal results from the metal atoms having (1) high electronegativity (2) high ionization energy (3) highly mobile protons in the nucleus (4) highly mobile electrons in the valence shell

All atoms are neutral. explain the basis of this fact
