A water company allows a maximum of 500mg per dm^3 of surface ions in drinking water.
A sample of drinking water contains 44mg per dm^3 of sulfate ions
Calculate the percentage (%) of the maximum allowed mass of surface ions in the sample of drinking water

Camels store the fat frustration (C57H110O6) in the hump. As well as being a source of energy, the fat is a source of water, because when it is used the reaction 2C57H110O6(S) + 163O2(g)=+114CO2(g) + 110H2O(I)

Explain why porkfish and the panamic porkfish different species

. Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. Explain, using your knowledge of chemical kinetics, why meat spoils less rapidly when left unsliced.

Now we know the percent expansion of water for every degree of temperature increase. Now, let s apply this to a real situation. Imagine a swimming pool 25 m long and 15 m wide. If the water is exactly 2 m deep when the water temperature is 20 ° C, how deep will the water be if the temperature increases to 21 ° C?
