Can a window pane be considered a mineral?
hichkok12 [17]

Answer:

Explanation:

The glass (which does not crystallize even though it is accepted) of a window is NOT a mineral, since it is neither a substance of natural origin (although it is manufactured from natural components) nor does it have a defined crystalline structure, that is, the atoms they are not arranged in an orderly and regular way along axes and planes forming flat faces that keep a symmetry.

Remember that a mineral is defined as a solid, inorganic, homogeneous substance, of natural origin, with a crystalline structure and a determined and well-defined chemical composition within narrow margins and that has regular and characteristic physical properties.

Answer:

7.82x10^24 molecules of water

Explanation:

H2O=18.015 g/mol   Avogadro's #=6.022x10^23 molecules

0.234L x 1000g/1L x 1 mol H2O/18.015 g x 6.022x10^23 = 7.82x10^23 molecules of water

What is the slope of the line?
pychu [463]

Answer:

The slope of the line is -\frac{10}{7}.

Explanation:

The slope of the line (m) is the change in dependent variable (y) divided by the change in independent variable (x):

m = \frac{y_{f}-y_{o}}{x_{f}-x_{o}} (1)

If we know that (x_{o}, y_{o}) = (0, 2) and (x_{f}, y_{f}) = (1.4, 0), then the slope of the line is:

m = \frac{0-2}{1.4-0}

m = -\frac{10}{7}

The slope of the line is -\frac{10}{7}.
