Answer:
1470 kJ (to 3 sf)
Explanation:
(802)(1.83) = 1470 kJ (to 3 sf)
Explanation:
The given data is as follows.
Mass of apple sauce mixture = 454 kg
Heat added (Q) = 121300 kJ
Heat capacity () of apple sauce at = 4.0177
So, Heat given by heat exchanger = heat taken by apple sauce
Q =
or, Q =
Putting the given values into the above formula as follows.
Q =
121300 kJ =
=
Thus, we can conclude that outlet temperature of the apple sauce is .
Answer:
magnesium
Explanation:
because zinc does not react with water because it too forms a protective layer of insoluble.
Answer:
- <em>2.0 X 10²² molecules of AgNO₃</em>
Explanation:
Given 5.50 grams of AgNO₃, how many formula units of AgNO₃ are contained in the 5.50 grams of AgNO₃? (formula wt. of AgNO₃ = 169,87 g/mole).
Solution:
- 1st convert grams to moles => moles AgNO₃ = 5.50 g AgNO₃ / 169.841g AgNO₃ = 0.032377 mole AgNO₃
- 2nd calculate number of particles in 0.032377 mole AgNO₃
. Number AgNO₃ molecules in 0.032377 mole AgNO₃ = 0.032377 mole AgNO₃ X 6.023 x 10²³ molecules of AgNO₃ /1.0 mole AgNO₃ = 1.95007 X 10²² molecules of AgNO₃ in 5.50 grams of AgNO₃.
- The appropriate form of the answer should contain 2 Sig,Figs. based on the data point having the least number of sig.figs. in the given data. This then is 5.50 grams of AgNO₃ which has 2 sig.figs.
- <em>Therefore, the number of AgNO₃ molecules in 5.5 grams of AgNO₃ = 2.0 X 10²² molecules of AgNO₃.</em> (Note: 1.95 rounds to 2.0).
