Answer:
Explanation:
Chemical equation:
NH₃ + O₂ → NO + H₂O
The given reaction shows the formation of nitric oxide and water from ammonia and dioxygen in the presence of catalyst Pt. The catalyst speed up the reaction. This reaction is double displacement reaction.
The given equation is not balanced. That's why this reaction not follow the law of conservation of mass. Balanced equation is given below.
Balanced chemical equation:
4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(l)
This is the balanced equation. This follow the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
There are four nitrogen, ten oxygen and twelve hydrogen atoms are present on both sides of equation.
The answer is stars, It has enough gas and dust to make billions of more stars.
Hope that helps :D
Answer:
Volume of water it can hold 63000,000 cm³
Mass of water is 63000,000 g.
Explanation:
Given data:
Length of tank = 70.00 cm
Width of tank = 300.00 mm
Height of tank = 300.00 m
Volume of water it can hold = ?
Mass of water = ?
Solution:
First of all we will convert the units into same unit.
Width of tank = 300.00 mm × 1 cm / 10 mm = 30 cm
Height of tank = 300.00 m× 100 cm / 1 m = 30000 cm
Volume of water it can hold:
V = l×w×h
V = 70.00 cm × 30 cm × 30000 cm
V = 63000,000 cm³
Mass of water:
Density of water from literature = 1 g/cm³
d = m/v
1 g/cm³ = m/ 63000,000 cm³
m = 63000,000 g
Answer:
zinc and lead or copper and tin
Explanation:
these elements react both as an acid as well as a base
Mol (n) = 29.0
molar mass (M) Na = 23 g/mol
mass (m) = ?
m = nxM
m = 29.0x23
m = 667 g
mol (n) = 29.0
molar mass (M) Cl = 35.5 g/mol
mass (m) = ?
m = nxM
m = 29.0x35.5
m = 1029.5 g
