I believe the most harmful substance would be element C, this is because element C has a very long half life therefore it has a very slow rate of a decay. Half life of a substance it the time taken for substance to decay to half its original mass or amount.
Answer:
Weathering is the breakdown of rock by natural forces and chemical changes
Explanation:
The air and water (rain) are natural forces that breaks down rocks
Answer:
See explanation
Explanation:
Whether a ligand is strong or weak highly depends on its position in the spectrochemical series. Ligands that are found towards the left hand side of the series are weak field ligands while ions that occur towards the right hand side of the series are strong field ligands. The spectrochemical series is an arrangement of ligands in order of increasing magnitude of crystal field splitting.
Most of the strong field ligands have strong pi bonds and are capable producing greater crystal field splitting.
NH3, an and NO2 are all strong field ligands hence they produce long wavelengths and lead to the formation of diamagnetic complexes.
Answer:
A quantum of electromagnetic energy is called photon
Explanation:
A photon corresponds to an elementary particle that composes the light, without any internal structure that is known at the moment. Said particle carries visible, ultraviolet, infrared, X-ray, gamma and other forms of electromagnetic radiation particles. The photon can travel in a vacuum at a constant speed and lacks mass or electric charge.
Answer:
The answer to your question is letter d. Sr(ClO₃)₂
Explanation:
Data
Reactants HClO₃ and Sr(OH)₂
This is a neutralization reaction because the reactants are a base (Sr(OH)₂) and an acid (HClO₃).
The products in a neutralization reaction are always water and a salt.
Balanced chemical reaction
Sr(OH)₂ + HClO₃ ⇒ H₂O + Sr(ClO₃)₂
