Answer: - 5.00 kJ

Explanation:

1) The heat evolved during the reation is proportional to the number of moles dissolved.

2) Proportionality = ratio is constant

<span>3) δh°soln of HNO3 is –33.3 kJ/mol => ratio 1

                  -33.3 kJ
ratio 1 = ---------------------
                 1 mol HNO3

4) ratio 2

        x
--------------
0.150 mol     
</span>
5) proportion

ratio 1 = ratio 2

        x                -33.3 kJ
--------------- =    -------------- => x = 0.150 mol * (-33.3kJ) / 1 mol = - 4.995 kJ ≈
0.150 mol              1 mol

≈ - 5.00 kJ

Water is dripping into a bucket at a rate of 51 drops per minute. if each drop has a volume of 0.050 milliliters, what volume of
serious [3.7K]

112.2 milliliters volume of water will drip into the bucket in 44 minutes.

<h3>What is volume?</h3>

How much space an object or substance takes up. • Measured in cubic meters (m3), liters (L) & milliliters (mL).

Total drop = Drops per minute X time

= 51 drops per minute X 44 minutes

=2244 drop

Volume of water will drip into the bucket in 44 minutes

=Total drop X Volume of each drop

=0.050 milliliters X 2244 drop

=112.2 milliliters

Hence, 112.2 milliliters volume of water will drip into the bucket in 44 minutes.
