Answer:
Heat will flow from the air in the container into the cube.
Explanation:
Heat flows from<em> places with higher</em> temperature to <em>places with lower </em>temperature.
With that information in mind then we can see that the cube of copper has a lower temperature than the air in the container (85°C > 5°C), thus heat will flow into the cube.

Answer:
128.4 g
Explanation:
Step 1: Given data
- Mass percent of element X in X(NO₃)₂: 52.55%
- Mass of the element X in the sample: 67.50 g
Step 2: Determine the total mass of the sample
The mass percent of element X in X(NO₃)₂ is 52.55%, that is, there are 52.55 g of X every 100 g of X(NO₃)₂. Then, the mass of X(NO₃)₂ that contains 67.50 g of X is:
67.50 g X × 100 g X(NO₃)₂/52.55 g X = 128.4 g X(NO₃)₂
