What is the parent isotope when Cl-33 is formed during a beta decay?

Chemistry
1 answer:
zzz [600]3 years ago
7 0

Answer:

33/16 S

Explanation:

In beta decay, the atomic number of the daughter nucleus increases by one unit while the mass of the daughter nucleus remains the same as that of the parent nucleus.

Hence, if we know that a beta decay has occurred, then the parent nucleus must have the same mass as its daughter nucleus but have an atomic number that is less than that of the daughter nucleus by only one unit, hence the answer above.

12. Which gas has the greatest kinetic energy at STP?
balandron [24]

Answer:

d. none of the above (all have the same kinetic energy)

Explanation:

The kinetic theory of gases states that the molecules of an ideal gas experience a constant random motion.

At standard temperature and pressure (STP), the kinetic energy of an ideal gas such as hydrogen, argon, neon, sodium, oxygen, helium, magnesium, beryllium, nitrogen, carbon, fluorine, chlorine etc are all the same.

The standard temperature and pressure (STP) of an ideal gas is 273K and 100 kPa.

Hence, all of the gases have the same kinetic energy at standard temperature and pressure (STP).

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

A student is learning about a particular chemical element. The element is a metal that readily forms ionic salts with nonmetals
seropon [69]

Answer:

Group 2

Explanation:

Because group 2 is very reactive and forms salts with other non metals. Example Calcium Chloride. Calcium is from group 2, forms ionic salts with other non metal, and exists as solid at standard temp and pressure.

Why does a hypothesis become a scientific theory
Marina86 [1]

Answer:

Explanation:

If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon. ... Tanner likens theories to a basket in which scientists keep facts and observations that they find

Using the potential given below, calculate the activity of cl^- in 1M KCl solution.
MissTica

Answer:

Explanation:

E° (calomel electrode) = 0.268 v

E( calomel electrode, 1M KCl) = 0.280 v

For calomel electrode

E = E^0 _( Hg^+/Hg ) - \frac{.059}{2} \times log( a_{cl^-} )^2

.280 = .268 - \frac{.059}{2} \times log( a_{cl^-} )^2

.012=  - \frac{.059}{2} \times log( a_{cl^-} )^2

log( a_{cl^-})^2= - .4067

a_{cl^-_}  = 0.626 .
