Answer:
Q = 5949.35 J
Explanation:
Given that,
The mass of water, m = 189.5 grams
Initial temperature, T = 16.4 °C
Final temperature, T' = 8.9°C
We need to find the thermal energy the water use to melt the ice cube. The thermal energy is given by :
Where
c is the specific heat of the water, c = 4.186 joule/gram °C
So,
So, the required amount heat is equal to 5949.35 J.

Answer:
0.12 & of NaCl
Explanation:
Determine the percentage of NaCl in the broth
First of all, we convert the mass from mg to g
340 mg . 1g/ 1000 mg = 0.340 g
Now we can calculate the %
(0.340 g / 286.7 g) . 100 = 0.12 %
Answer:
Phosphorus atoms will be paramagnetic. Iodine atoms will be paramagnetic. Germanium atoms will also be paramagnetic.
Explanation:
Phosphorus has 3 unpaired electrons. Iodine has 1 unpaired electron. And Germanium has 2 unpaired electrons. But all these simple compound will be diamagnetic because they pair their electrons on molecular orbitals.
