Buffers are substances that help resist shifts in pH by Question 10 options: 1) releasing H in acidic solutions. 2) donating H t
ehidna [41]

Answer:

5) donating H to a solution when they have been depleted and accepting H when they are in excess.

Explanation:

A buffer solution is a solution that undergoes a negligible change in pH in addition of moderate quantities of acid or alkali. In other words, a buffer solution is one that resists a change in pH on addition or dilution of small amounts of acids or alkalis.

So, from the given question:

Buffers are substances that help resist shifts in pH by donating H to a solution when they have been depleted and accepting H when they are in excess.

when 27 g of water absorbs 1,5000 joules of heat energy the temperature of the water is raised to 57.7 what is the initial tempe
taurus [48]

Answer:

The initial temperature of the water is -75.08 K.

Explanation:

Given that,

Mass of water, m = 27 g

Heat absorbed, Q = 1,5000 J

Final temperature of water, T₂ = 57.7 K

The specific heat of water is 4.184 J/​g-K

We know that,

Q=mc\Delta T\\\\Q=mc(T_2-T_1)\\\\\dfrac{Q}{mc}=(T_2-T_1)\\\\T_1=T_2-\dfrac{Q}{mc}

Put all the values,

T_1=57.7-\dfrac{15000}{27\times 4.184 }\\\\=-75.08\ K

So, the initial temperature of the water is -75.08 K.
