we know that the ant traves 50 meters in 100 seconds, and we need to figure out how many meters per second that ant is travelling. To do this, you simply need to figure out 1% of the current value, because 1 second is one hundredth of the hundred seconds in the original given values. So, just divide both the 50 meters by 100 and the seconds by 100 to get the speed on the ant in meters per second. 50/100 is 0.5, so the ant is traveling 0.5 meters per second.
Arianna has discovered a substance that is a liquid at room temperature. Through testing, she finds that it ignites quickly and burns easily, but does not dissolve in water.
How would you classify the substance? What use might it have?
The required result about the solubility of KI at 10C is measured to be 31.2g per 100g of water.
Every solution contains a volume and that gets changed radically when the dissolution comes into existence. The result can be seen by inspecting the solubility in mol⋅L−1.
If we look closely to understand the solubility of KI, either at 10C or at any other temperature, you can ease it by a trick. The solubility of potassium bromide is approx twice its value.
Any chemical reaction must follow the law of conservation of mass. Meaning that mass cannot be created nor destroyed. Since all chemical reactions must follow this law, no matter what reaction happens, mass is conserved.
