Answer:
the sun goes away and takes heat with it
Explanation:
The atomic mass of an element is a result of the weighted average of the masses of its corresponding isotopes.
<span>We are given: </span>
<span>Sb-121: mass of 120.9038 amu, x abundance </span>
<span>Sb-123: mass of 122.9042 amu, 1-x abundance </span>
<span>To be able to calculate the atomic mass of antimony, we multiply the percent abundances of the isotopes by their respective atomic masses. Then, we add,</span>
<span>Atomic mass = (Atomic Mass of Sb-121) (% Abundance) + (Atomic Mass of Sb-123) (% Abundance )</span>
121.760 amu = (120.9038 amu)(x) + (122.9042 amu)(1 -x)
<span>Solving for x,</span>
<span>120.9038x + 122.9042 -122.9042x = 121.760</span>
<span>x = 0.57096 or 57.096% </span>
1-x = 1-0.57096 = 0.42904 or 42.90%
<span> Ag(NH3)2Cl + 3HNO3 = AgNO3 +2NH4NO3 + HCl </span>
<span>or
Ag(NH3)2Cl + HNO3 = Ag(NH3)2NO3 + HCl this the complete balanced equation
now remove spectator ions to get net ionic equation
so
</span>
<span>
2H+ + 2NO3- + [Ag(NH3)2]+ Cl- -> AgCl + 2NH4+ + 2NO3- 2NO3- 2H+ [Ag(NH3)2]+ + Cl- -> AgCl + 2NH4+
</span>hope it helps
Answer
A reactant is a substance that is present at the start of a chemical reaction. These are what breakdown to form products and its always to the right.
A product is a substance that is present at the end of a chemical reaction. These are what are formed after the reactants are broken down, the end result.
The invention of the Telescope led to the discovery of Cells.
