liquid 1 reacts with liquid 2 producing a solid and a gas.Using this scenario which supports the law of conservation of mass?
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
According to law of conservation of mass, the mass of reactants equal to the mass of products.
Therefore, when liquid 1 and liquid 2 reacts then their respective mass will be equal to the mass of products.
In a chemical equation, reactants are written of the left hand side whereas products are written on the right hand side.
Hence, we can conclude that following equation supports law of conservation of mass.

Answer : All possible values of 'ml' for the following orbitals are:
(a) At l = 3,
(b) l = 0, 1
At l = 0,
At l = 1,
(c) At l = 1,
Explanation:
There are 4 quantum numbers :
Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from . When l = 2, the value of
will be -2, -1, 0, +1, +2.
Spin Quantum number : It describes the direction of electron spin. This is represented as The value of this is
for upward spin and
for downward spin.
(a) l = 3 then the value of 'ml' is,
At l = 3,
(b) n = 2 then the value of 'ml' is,
l = 0, 1
At l = 0,
At l = 1,
(c) n = 6 and l = 1 then the value of 'ml' is,
n = 6
l = 0, 1, 2, 3, 4, 5
At l = 1,
The answer is; A
The force or weight and distance on both sides of the fulcrum is given by the following ratio;
MA = Fb/Fa = a/b (MA = Mechanical Advantage)
The greater the distance from the fulcrum on which force is applied to lift a load on the other side of the fulcrum, the less the effort required.
