1.炭火炉燃烧炽热时,在往炉膛底的热灰上喷洒少量水的瞬间,炉子的火更旺,这是因为.如果烧去同量的碳,喷洒过水和没有喷洒过水的炭火炉放出的总热量(填是否相同),因为. 2.汞蒸发到空气中有毒.在汞蒸气浓度为10-5kg·m-3的空气中停留1～2天就会发生汞中毒的症状.因此必须采取措施防止汞中毒. (1)万一把汞洒出,可以在溅洒有汞滴处撒一层硫磺粉.写出化学方程式.
1. When the charcoal stove is burning hot, the fire of the stove is more prosperous at the moment when a small amount of water is sprayed on the hot ash at the bottom of the furnace. This is because if the same amount of carbon is burned, the sprayed water and the charcoal fire that has not been sprayed with water are burned. The total heat released by the furnace (filling is the same), because. 2. Mercury vaporizes into the air toxic. In the mercury vapor concentration of 10-5kg · m-3 in the air to stay 1 to 2 days will occur mercury poisoning symptoms. Therefore, measures must be taken to prevent mercury poisoning. (1) Thousands of mercury should be spilled, and a layer of sulphur powder can be sprinkled with mercury. Draw the chemical equation.
