Wow, I'm ten trying to find the answer to this haha.

MATH
A ball is dropped from a height of 64 feet. It's height above the earth is the feet given by h(t)=-16t^2+64, where t is the number of seconds after it is dropped a Find h(1) b how long does it take the ball to fall to the earth

Chemistry
I was just wondering whether HCl and C6H5OH on the reactant side together, or am i supposed to separate the two into two different reaction equations, and then do ICE from there? Because I'm not sure how to create a acid-base reaction with HCl and C6H5OH together on one si...

How many electrons are transferred in the reaction of hydrogen peroxide with iron (II) ion in acidic solution to form iron (III) ion and water?

chemistry
A standard solution of FeSCN2+ is prepared by combining 9.00 mL of 0.200 M Fe(NO3)3 w/1.00 mL of 0.0020 M KSCN. The equilibrium concentration of FeSCN2+ ([FeSCN2+]std) for this standard solution is assumed to be ____ M.

Chemistry
The concentration and volume of reagents combined in each trial are listed in the table below: Trial 00020 M 00020 M H2O(mL) Fe(NO3)3(mL) KSCN (mL) 1 5 2 3 2 5 3 2 3 5 4 1 4 5 5 0 Initially (right after combining and before any reaction occurs) the concentration of Fe3+ in tri...

chemistry
The standard solution of FeSCN2+ (prepared by combining 9.00 mL of 0.200 M Fe(NO3)3 w/1.00 mL of 0.0020 M KSCN) has an absorbance of 0.510. If a trial's absorbance is measured to be 0.250 and its initial concentration of SCN¡V was 0.00050 M, the equilibrium concentra...
