Suppose you mix 100.0 g of water at 23.0 oC with 75.0 g of water at 75.7 oC. What will be the final temperature of the mixed water, in oC? Type

Explanation:

Let final temperature be T.

Heat lost by hot water

mass x specific heat x fall in temperature

75 x s x ( 75.7 - T )

Heat gained by cool water

= 100 x s x ( T - 23 )

heat lost= heat gained

75 x s x ( 75.7 - T )   = 100 x s x ( T - 23 )

5677.5 - 75 T= 100 T- 2300

175 T= 7977.5

T = 45.6⁰C .

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
