Answer: NH3 and H2O
Explanation:
NH4OH(l) --> NH3(g) + H2O(g)
Ammonia liquor, NH4OH is an highly unstable hydroxide of ammonium, hence it decomposes on heating to produce ammonia gas, NH3 which is liberated to the surroundings and water, H2O evaporated as steam. In a reverse reaction, ammoniacal liquor is formed by dissolving gaseous ammonia in cold water.
Thus, the products of NH4OH break down are NH3 and H2O
Answer:
The density of the block is 2.827 grams/ cubic inch
Explanation:
The density of the block can be obtained by dividing the given mass of the block by its volume.
Density = mass / volume
The mass of the block given is 435.5 grams
The volume of the block can be obtained by using the formula:
Volume = Length X breadth X height
Volume = 3.5 X 8 X 5.5 = 154
There fore the density will be 435.5 / 154 = 2.827 grams/ cubic inch
Answer:
1,2,5
Explanation:
Hydrogen can't really be classified into any group in the periodic table because it doesn't have properties that match that of any group exactly. However it exhibits a property of group 1A (formation of a univalent positive ion) and that of group 7A (formation if a univalent negative ion). It contains only one electron, hence this outermost electron is not shielded at all from the nucleus.
