Answer:
The statement is true
Explanation:
Any physical quantity has a unique dimensional representation and when we change the dimensions of any physical quantity it looses it's original form. while as unit conversion is applicable to physical quantities of same nature as speed can be converted from kilometers per hour to miles per hour or meters per second, changing the units of any physical quantity into different unit's but of same dimensional formula only changes a magnitude of the physical quantity as in the above case the speed will be speed no matter whatever be the units.
since 
are not the units of velocity but of volumetric rate of flow we cannot convert this quantity into velocity by only unit conversion
Answer:
2 moles of SO₂
Explanation:
Equation of reaction
H₂S + 3H₂SO₄ → 4H₂O + 4SO₂
From the equation of reaction above,
1 mole of H₂S will produce 4 moles of SO₂
1 mole of H₂S = 4 moles of SO₂
0.5moles of H₂S = zmoles of SO₂
z = (0.5*4) / 1
z = 2 moles of SO₂
0.5 moles of H₂S will produce 2 moles of SO₂

Answer:
-272.604 °C
Explanation:
The metals can conduct electricity, but this conduction has some resistance, and there're dissipations in the energy during the conduction. Some material has the ability, at very low temperatures, to conduce electricity without the resistance. This ability is called superconducting.
The mK corresponds to the miliKevin, and 1 K = 1000 mK, thus, the temperature in Kevin is 0.546 K.
T(K) = T(°C) + 273.15
T(°C) = T(K) - 273.15
T(°C) = 0.546 - 273.15
T(°C) = -272.604 °C
