Answer: -

When bismuth-212 undergoes alpha decay, it becomes ²⁰⁸Tl

Explanation: -

Mass number of ²¹²Bi = 212

Atomic number of ²¹²Bi = 83

When alpha decay occurs the mass number decreases by 4 and the atomic number decreases by 2.

Mass number of daughter = 212 - 4 = 208

Atomic number of daughter = 83 - 2 = 81

It is the atomic number of Thallium Tl.

Thus the daughter nucleide is ²⁰⁸Tl.

Answer:

Thallium-208 + and alpha particle

Explanation:

Atomic number of Bismuth-212 is 83. The resulting nucleus after the emission of alpha particle has mass number 208 and atomic number 81. Atomic number 81 corresponds to Thallium-208.

Enter a balanced equation for the dissolution of caco3.
Tatiana [17]

Answer:

CaCO3(aq) → Ca2+(aq ) + CO3 2-(aq)

Explanation:

  • Dissolution reactions are reactions that occur when a solute either in gaseous, liquid, or solid form dissolves in a solvent such as water to form a solution.
  • In this case we are given Calcium carbonate (CaCO3) which undergoes dissolution according to the equation;
  • CaCO3(aq) → Ca2+(aq ) + CO3 2-(aq)
  • Then<em><u> the bicarbonate ion combines with two protons from water to form a weak acid H2CO3. The weak acid is then broken down to form CO2 and H2O since its unstable.</u></em>

A force of 2,500 pounds drags a truck 30 feet in 1/2 minute.
scoray [572]
The right subject for this question is physics.

To calculate the work you use the formula:

Work = force * displacement

Work = 2500 pounds * 30 feet = 75,000 pounds - feet



To calculate the power you use the formula:

power = work / time

Power = 75,000 pound - feet / 30 seconds = 2300 pound-feet / second.
