Answer: Nuclear decay rates are constant

Explanation: Nuclear or radioactive decay occurs when energy is lost in unstable atoms, with emitting radiation. In this case, there are radioactive alpha, beta, gamma and other particles. In fact, this process presupposes the spontaneous transformation of unstable atomic nuclei. The characteristic of such processes is half-life, which represents a time period necessary for half of the amount of radioactive material to decay. It is not always predictable when a particular radioactive particle from an unstable atomic nucleus will be emitted, but the decay rate over time is constant.

Wich has more energy rolling down a hill - a bowling ball or soccer ball? Explain your answer

goldfiish [28.3K]

Answer:

Bowling ball

Explanation:

They are traveling at the same speed, but the bowling ball has more mass. The bowling ball has more kinetic energy because more force is needed to stop the rolling bowling ball. Two balls with different masses moving at the same speed have different amounts of kinetic energy.

Its atom contains 50 electrons and 70 neutrons

Tcecarenko [31]

Tin-120 because an atom has to have a neutral charge. If an atom has 50 electrons it must have 50 protons unless it's an ion. Add 70 to the atomic mass because it has 70 neutrons on top of 50 protons. That equals to 120. Tin has an atomic number of 50 (meaning it has 50 protons) and it has roughly an atomic mass of about 118. If the given has 70 neutrons then it's a isotope of tin.

Suppose a helium-3 nuclide transforms into a helium-4 nuclide by absorbing a proton and emitting a positron. Complete the nuclea

saw5 [17]

Answer: The nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.

Explanation:

Nuclear reaction are defined as the reactions in which nucleus of an atom is involved.

Positron emission is defined as the emission process in which positron particle is emitted. In this process, a proton gets converted to neutron and an electron neutrino particle.

$_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e$

The chemical equation for the reaction of He-3 with a proton follows:

$_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0e$

Hence, the nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.

If 5.0 L of carbon dioxide gas are produced by the reaction below at STP, how many liters of oxygen gas were used in the reactio

Alik [6]

One mole of gas occupies 22.4 liters, 5*1/22.4=0.22 moles of carbon dioxide ration of oxygen to carbon dioxide is 1:2 so we divide 0.22 by 2 we get 0.11 moles of oxygen 1 mole occupies 22.4 litres, what if 0.11 moles of oxygen were used what volume would it occupy. so 0.11*22.4/1=2.5L
