Answer:
- word equation: lead +nitrate +potassium iodide +sodium nitrate =potassuim nitrate +lead nitrate +hydrogen
2. Notice that in writing the net ionic equation, the positively-charged silver cation was written first on the reactant side, followed by the negatively-charged chloride anion.
Answer:
They must have the same number of protons.
Explanation:
Protons determine the identity of an element. However, the neutrons can vary, resulting in different masses.
Answer: C) the splitting of a nucleus released a large burst of energy
Explanation:
nuclear fission occurs when an isotope (usually unstable) is hit with particles such as neutrons and splits, resulting in an extreme burst of energy.
for instance, the atomic bombs developed by the U.S. during WWII were products of nuclear fission in which plutonium-239 and uranium-235 were struck by a neutron that hit either nucleus of either isotope. The result was the neclus split into fragments that released huge amounts of energy snd the fission process became self-sustaining as neutrons produced by the splitting nucleus hit other nuclei and produce more fission, causing a chain reaction.
