<h3><u>Answer;</u></h3>
<u> = 1319.45 Joules </u>
<h3><u>Explanation;</u></h3>
Kinetic energy is the energy possessed by a body in motion;
It is given by the formula; 1/2mv², where m is the mass of the body and v is the velocity.
mass = 89.5 kg and v =5.43 m/s
Therefore;
Kinetic energy = 1/2 × 89.5 × 5.43 ²
<u> = 1319.45 Joules </u>
Iconic compounds are electrolytes because they dissociate into ions when dissolved in water. Many molecules compounds are noneelectrolytes
Answer:
FeCl: Ferric Chloride (also called iron chloride), comes from Fe (ferrum, or iron), and Cl (Chlorine)
HNO: Nitroxyl, from N (Nitrogen), and the acidic nature of a radical ending in -yl.
NaSO: Sodium sulfate, Na (Sodium), S (Sulfur), O (Oxygen).
SO: Sulfur monoxide (Mono-One), O (Oxygen) and S (Sulfur).
Isotopes of an element have same atomic number (number of protons) but vary in the mass number (number of neutrons). The chemical reactivity of an element is not affected by the change in mass number. So, for stable isotopes of Oxygen, (Oxygen-16, Oxygen-17 and Oxygen-18) the biochemical pathway of oxygen breathed in during respiration remains unaffected even with different isotopes. Only the radioactive isotopes of oxygen when breathed in may cause serious health hazards as they emit radiations that may damage the internal organs in the body.
Answer:
Equilibrium constant is: 1.09
Explanation:
The proposed equilibrium is:
2NH₃(g) ⇄ 3H₂(g)+N₂(g)
Concentrations are: [NH₃] = 0.250 M; [H₂] = 0.440 M; [N₂] = 0.800 M
Expression for Kc is: [H₂]³ . [N₂] / [NH₃]²
We replace data → Kc = (0.440³ . 0.800) / 0.250²
Kc = 1.09
Remember that equilibrium constant has no units and it depends on T°
