The radioactive atom R 88 210 a is an alpha emitter. What nucleus does it produce?
olasank [31]

Answer:

X 86 206

Explanation:

Radioactive atoms are nuclei that can under go disintegration to emit either an alpha particle, beta particle or gamma radiation. The process could be spontaneous or stimulated.

When a radioactive atom R 88 210 emits alpha particle, it would produce an element with atomic number 86 and mass number 206 i.e X 86 206. An alpha particle is usually a helium nucleus.

                     R^{210} ⇒ x^{206} + He^{4} + energy

Consider the proportionality below.
svet-max [94.6K]

Answer:

Ideal gas law

Explanation:

The expression is the ideal gas law when properly written;

              PV = nRT

where P is the pressure of the gas

V is the volume of the gas

n is the number of moles of the gas

R is the gas constant

T is the temperature

The ideal gas law is derieved from the three major gas laws;

--- Boyle's law, Charles's law and Avogadro's law

Mamont248 [21]

Answer:

A

Explanation:

With chemical reactions, there are various factors that affect the rate of the reaction. One of these is temperature.

When you raise the temperature, the reaction will move faster. Why? Temperature is directly correlated with the kinetic energy (basically, the energy that makes the particles move). Higher temperatures mean higher kinetic energies. Particles with higher kinetic energies move faster, which makes them more likely to collide. When collisions occur more frequently, the reaction follows through more quickly.

Thus, when Julissa warms the solutions, she will see that bubbling and white solid formation (the products of the reaction) occus faster. So, the answer is A.

Hope this helps!
