Zinc-64 undergoes beta decay as shown:

Chemistry
1 answer:
IrinaK [193]3 years ago
7 0

Symbol for X : \tt _{31}^{64}Ga

<h3>Further explanation </h3>

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

  • alpha α particles ₂He⁴
  • beta β ₋₁e⁰ particles
  • gamma particles ₀γ⁰
  • positron particles ₁e⁰
  • neutron ₀n¹

Zinc-64 undergoes beta decay, so :

The atomic number will increase by +1, and the mass number will remain the same

So that the atomic number:

30 + 1 = 31

The element with atomic number 31 is Gallium

Reaction

\tt _{30}^{64}Zn\Rightarrow _{31}^{64}Ga+~_{-1}^0\beta

Write 10,847,100 in Scientific Notation with 4 significant figures.
Lisa [10]

Answer:

The number 10,847,100 in Scientific Notation is 1.0847x10^{7}

Explanation:

Scientific notation is an easy form to write long numbers and it is commonly used in the scientific field. To write a long number in a shorter way it is necessary to 'move' the decimal point to the left the number of positions that are necessary until you get a unit. Then you write the number and multiplied it by 10 raised to the number of positions you moved the decimal point. In this case, it is necessary to move the decimal point 7 positions so, we multiply the number by 10 raised to 7.

A reaction occurs in a calorimeter, resulting in the starting and final temperatures shown below. What can you say about the rea
Pavlova-9 [17]

Answer:

The reaction is exothermic and ΔH is negative

Explanation:

An exothermic reaction is a chemical reaction that releases energy in the form of heat. It is the opposite of an endothermic reaction in which energy is absorbed. It is expressed in a general thermochemical equation: reactants → products + energy.

We can know that a reaction is exothermic by observing the calorimeter to know if there is an increase in temperature. Remember that an exothermic reaction leads to evolution of heat. This is observed physically as a rise in temperature.

The calorimeter initially read 21.0 and finally read 38.8 at the end of the reaction. This implies that heat was given out in the process. The reaction is exothermic and ∆H is negative.
