Answer:
They take the form of heat.
Explanation:
Electromagnetic waves with wavelengths greater than 750 nm are infrared light.
They are not visible to human eyes, but we can feel them as heat on our skin.
B is wrong. It is UV light that causes skin cancer and sunburn.
C is wrong .Visible and UV light have shorter wavelengths.
D is wrong. Human eyes cannot see IR radiation

Explanation:
The electrolysis of nickel(II) iodide yields nickel solid and iodine gas.
In the oxidation half equation;
2I^-(aq)-------> I2(g) + 2e
In the reduction half equation;
Ni^2+(aq) + 2e -----> Ni(s)
These are the half equations of the process;
The overall equation is;
Ni^2+(aq) + 2I^-(aq)-------> NiI2
Common salt besides being used in kitchen can also be used as the raw material for making washing soda and baking soda.
The overall balanced reaction for washing soda preparation:
2NaCl + CaCO3 → Na2CO3 + CaCl2
NaCl is sodium chloride or common salt
Na2CO3 is sodium carbonate or washing soda
CaCO3 is calcium carbonate or limestone
The overall balanced reaction for baking soda preparation:
NaCl + CO2 + NH3 + H2O → NaHCO3 + NH4Cl
Baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or appears as a fine powder.
NH3 is ammonia
CO2 is carbon (II) oxide

Answer:
2.61 L
Explanation:
p1v1 = p2v2
p1v1 / p2 = v2
98 * 2 / 75 = v2 = 2.61 L
