Bromine has an atomic mass of 79.9 amu, but only has 2 naturally occurring isotopes, Bromine-79 and Bromine-81. If Bromine-80 do

es not exist, what does that suggest about the relative abundances of Bromine-79 and Bromine-81? PLEASE HELP ME! 25 POINTSSSSS

Educated Guess Here!

Since Br-80 does not exist, maybe that means Br-79 or Br-81 have very unequal abundances. For example, Br-79 may have 75% abundance whereas Br-81 may have 25% abundance.

Solid silver chloride, AgCI(s), decomposes to its elements when exposed to sunlight Write a balanced equation for this reaction
Mrac [35]

Answer: The coefficient in front of AgCl when the equation is properly balanced is 2.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Decomposition of silver chloride is represented as:

2AgCl(s)\rightarrow 2Ag(s)+Cl_2(g)

Thus the coefficient in front of AgCl when the equation is properly balanced is 2.

A natural atom possesses the atomic number of 13 and a atomic mass of 27. Three electrons are lost. From what region of the atom
Anarel [89]

Answer:

The electrons are lost from the valence shell (outermost electron shell) of the atom.

Explanation:

This is able to be inferred not only because valence electrons being lost first is a trend but also because the atom in question has actually 3 valence electrons (13-2-8 = 3).

Describe the physical and chemical weathering​
Stella [2.4K]

Answer:

Physical weathering is caused by purely mechanical changes to the rock, while chemical weathering is caused by chemical reactions.

Explanation:

Chemical weathering happens when the chemicals get diluted and dissolved in water and seep and percolate down the rock surfaces.

Physical weathering happens when rocks are fragmented into minor fragments while ensuring no alterations in their chemical makeup. The main causes behind physical weathering include spontaneous fluctuations in temperature like too high or too low heat or cold

Based on the chemical formula and state of matter, which of these substances will conduct electricity?
Sergeu [11.5K]

Answer:

CuSO4(aq)

Explanation:

The aqueous form of copper sulfate will conduct electricity.

The Solid form will not be a good conductor.

C₅H₁₂ will not conduct electricity

CO₂ will not conduct electricity

  • Copper sulfate is an ionic compound
  • In aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers.
  • This way, they are electrolytes.
  • In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
