Answer:
Algebra is an area in mathematics that uses variables, in the forms of letters and symbols, to act as numbers or quantities in equations and formulas. Geometry is an area in mathematics that studies points, lines, varied-dimensional objects and shapes, surfaces, and solids.
Explanation:
It is your own opinion on which is more difficult. In my opinion, Geometry is more difficult.
Answer:
"<em><u>A</u></em><em><u>L</u></em><em><u>U</u></em><em><u>M</u></em><em><u>I</u></em><em><u>N</u></em><em><u>U</u></em><em><u>M</u></em><em><u> </u></em>FOIL" will conduct heat much more effectively than black construction paper.
The chemical reaction would be expressed as follows:
HBr + LiOH = LiBr + H2O
We are given the volumes and corresponding concentration to be used for the reaction. We use these values to solve for the concentration of the other reactant. We do as follows:
0.253 mol LiOH / L solution ( 0.01673 L ) ( 1 mol HBr / 1 mol LiOH ) = 0.00423 HBr needed
Concentration of HBr =0.00423mol / .010 L = 0.423 M HBr
