No because it has less gravity and there is nothing that can run forever eventually the strings will wear out or the balls would stop

The answer is; B
The tip of the blue triangles points to the direction in which the cold front is moving. Also, note that the blue color represents a cold front (as opposed to a red color that represents warm front). A cold front occurs when a cooler air mass wedges down and replaces, at ground level, the rising warm air mass. The boundary between the two air masses exhibits cooling moisture that forms clouds and thunderstorms.
127.88 grams of ethanol were present at the beginning of the reaction
Explanation:
Firstly, let's make the combustion reaction:
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
By 1 mol of ethanol, you can make 3 mole of water.
Mole of water = Water mass / Molar mass
150g / 18g/m = 8.3 mole
3 mole of water came from 1 mol of ethanol
8.3 mole came from (8.3 .1)/3 = 2.78 mole of ethanol
Molar mass ethanol = 46 g/m
Mole . molar mass = mass
2.78 m . 46g/m = 127.88 g
