Use the reaction below for the combustion of methanol. Any type of stoichiometry problem is possible. 2CH3OH + 3O2 —> 2 CO2 + 4H2O
What mass of methanol is combusted in a reaction that produces 112 L of CO2 at STP?

No. an alpha particle is a pair of protons and a pair of neutrons, i.e. a helium

The answer is d- principle of faunal succession.

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
