The ways in which ammonia can be identified is mentioned in below pointers.
<h3>What is Ammonia ?</h3>
Ammonia is a compound of nitrogen and hydrogen with the formula NH3.
A stable binary hydride, and the simplest pnictogen hydride.
Ammonia is a colourless gas with a distinct pungent smell.
Biologically, it is a common nitrogenous waste,
Three ways in which ammonia gas can be identified is:
- It has a sharp characteristic odor.
- When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.
- It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.

The two properties which provide the greatest resistance to the flow of a current are the long and thin wires.
<h3>What is resistance?</h3>
Resistance is the quantity which define the flow of current from any wire and it is represented as:
R ∝ l/A, where
l = length of wire
A = cross section of wire
From the relation it is clear that resistance is high in long wire and thin wire.
So, required properties are long and thin.

Answer:
300 kPa
Explanation:
P2=P1V1/V2
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
Answer:
2 Pb(OH)2 + 2H2SO4 => 2 PbSO4 + 4 H20
Explanation:
Since there's no "?" shown in the equation, let's balance it and solve it entirely.
Pb(OH)2 + 2H2SO4 => PbSO4 + 2H20
1Pb + 10O + 6H + 2S ≠ 1Pb + 6O + 4H + 1S → it needs to be balanced.
To do this, let's start by looking at the elements that are only presnet once on each side:
On the products half, S is only present in PbSO4 → if we look at the reagents half, we can see it needs a "2" → then Pb is multiplied by 2 too → so Pb(OH)2 on the reagents half will also need a "2" → final count on O and H on the reagents side: 12O and 8H → to balance it, you need 4 water molecules on the products side.

Is Not shrinking
Is Not Expanding
It Does contain billions of galaxies
And it is Not about 10 billion years old
Hope this Helps. :)
