Given that <span>sample a has a higher melting point than sample
b. Therefore, sample a is a longer chain of a </span><span>fatlike solid substance. It could also be that the bonds present in sample a is much stronger which will require more energy to break. Hope this answers the question.</span>
Answer:
ti determines which number of elements you got or have
Explanation:
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.
Answer:
pH of 4
Explanation:
Upon comparing a solution with a pH value of 4 and that having a pH of 7, you will realize that it has a pH difference of 3 although the concentration of ions of hydrogen having a pH of 7 is 1000 times greater than being at a pH of 4.
