Science, asked by rishis34, 3 months ago

Lavoisier, along with other scientists, noted that many compounds were composed of two or more elements and each such compound had the same element have same proportions, irrespective of where the compound came from or who prepared it.

In a compound such as water, the ratio of the mass of hydrogento the mass of oxygen is always 1:8, whatever the source of water. Thus, it99 of water is decomposed, 1g of hydrogen and 8 g of oxygen are alwaysobtained. Similar in ammonia, nitrogen and hydrogen are always presentin the ratio 14:3 by mass, whatever the method or the source from whichit Is obtained.

1lWrite the mass ratio of elements hydrogen and oxygen present in water.

2)Name the law of chemical combination explained in the given paragraph.

3)Define the law.

4) Write the mass of nitrogen and hydrogen obtained when 349 of ammonia is decomposed?

5)What mass of oxygen gas would be required to react completely with 3g of hydrogen gas to form water?​
