Answer: A. are relatively far apart
Explanation:
Compressbility is the ability of compound to reduce in size when pressure is applied.
Gaseous state is a state in which the particles are loosely arranged and have a lot of space between them. Thus molecules can be easily compressed.
They have highest kinetic energy. This state has indefinite volume as well as shape. The molecules in the gaseous state move faster with an increase in temperature as the kinetic energy increases with increase in temperature.
Thus most gases are easily compressed is that the molecules in a gas are in constant motion are relatively far apart.
<span>Mg + O2 > MgO. In reactant side, 2 O atoms and 1 Mg are present. In product side, 1 Mg and O atoms are present. Put 2 in product side to balance O atoms and 2 at Mg in reactant side to balance Mg atoms. Therefore the balanced equation becomes, 2Mg + O2 ----> 2MgO. Hope it helps.</span>
Answer:
Nickel and Titanium
Explanation:
Nitinol is an alloy of Nickel and Titanium. It posesses two properties such that,
- The shape memory effect
- Super elasticity
Shape memory is the ability of nitinol to undergo deformation at one temperature, stay in its deformed shape when the external force is removed.
Superelasticity is the ability for the metal to undergo large deformations and immediately return to its undeformed shape upon removal of the external load.
Hence, the correct option is (b) "Nickel and Titanium".
Fe3O4 + 4H2 = 3Fe + 4H2O
Fe3O4 + 4H2SO4 = Fe2(SO4)3 + FeSO4 + 4H2O
