It is crystalline in nature which is used in explosives,buffers and fertilisers it is also used to treat low blood levels(hypokalemia)
Answer:
55 g
Explanation:
First, we have to look for the solubility of KNO₃ at 60°C, considering that the solubility is the maximum amount of solute that can be dissolved in 100 grams of solvent, that is, the concentration of a saturated solution.
The solubility of KNO₃ at 60°C is 110.0 g of KNO₃ per 100 g of water. The mass of KNO₃ that must be dissolved in 50 g of water to make a saturated solution is:
50 g H₂O × (110.0 g KNO₃/100 g H₂O) = 55 g KNO₃
Well insulated houses use less energy to keep them warm. This means that less carbon dioxide, a greenhouse gas, is released into the atmosphere from burning of fossil fuels (coal, oil and gas) in our power stations and central heating boilers. Global warming is occurring because large volumes of greenhouse gases – including carbon dioxide – are accumulating in the Earth’s atmosphere. This causes the planet’s average air and ocean temperatures to increase and sea levels to rise, resulting in increasingly severe weather conditions. This effect is called climate change and it’s already happening. By improving the insulation of your home, you will be playing your part in reducing the effect of global warming.
Answer:
the more time you leave it to boil the water will turn to gas but if you leave it to heat for a short period of time it would probably stay the same
