Answer:

Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless ramp is equal to the gravitational potential energy of the block at the top of the ramp. This value is proportional to the square of the block’s velocity at the bottom of the ramp. Therefore, the block’s final velocity depends on the height of the ramp but not the steepness

Write balanced chemical equations for the complete neutralization reactions that take place when the following acids are titrate

swat32

Answer:

(a) $NaOH_{(aq)} + HCl_{(aq)} --> NaCl_{(aq)} + H_2O_{(l)}$

(b) $NaOH_{(aq)} + CH_3COOH_{(aq)} --> CH_3COONa_{(aq)} + H_2O_{(l)}$

(c) $H_3PO_4_{(aq)} + 3NaOH_{(aq)} --> 3H_2O{(l)} + Na_3PO_4_{(aq)}$

Explanation:

For a reaction involving sodium hydroxide and hydrochloric acid, the balanced equation of reaction is:

$NaOH_{(aq)} + HCl_{(aq)} --> NaCl_{(aq)} + H_2O_{(l)}$

For a reaction involving sodium hydroxide and acetic acid, the balanced equation of reaction is:

$NaOH_{(aq)} + CH_3COOH_{(aq)} --> CH_3COONa_{(aq)} + H_2O_{(l)}$

For a reaction involving sodium hydroxide and phosphoric acid, the balanced equation of reaction is:

$H_3PO_4_{(aq)} + 3NaOH_{(aq)} --> 3H_2O{(l)} + Na_3PO_4_{(aq)}$
