Answer:
Order of decreasing: CaS> LiCl> CsCl. That is CsCl has the lowest lattice energy.
Explanation:
LATTICE ENERGYcan be used to estimate the STRENGHT of the bonds in an ionic compound.
ATOMIC RADIUS is a function of lattice energy. The atomic radius INCREASES as you move DOWN a group. LATTICE ENERGY DECREASES as ATOMIC RADIUS increases.
Considering the cations Lithium +1, and Caesium +1 , as one move DOWN the GROUP the ions get larger, this causes the LATTICE ENERGY TO DECREASE DOWN THE GROUP. This means that between lithium in and caesium ion, the Caesium ion has LOWER LATTICE ENERGY as COMPARE TO LITHIUM ION.
AS ONE MOVE ACROSS THE PERIOD, POSITIVE IONS BECOMES MORE CHARGED, and the MORE THE CHARGE, THE GREATER THE LATTICE ENERGY.
Therefore, Calcium ion will have higher lattice energy than Lithium ion.
Answer:
37.8g/ 10.81g/mol = 3.4968...moles
Answer: A comprehensive legal term for uniform standards ascribed to the quantity, capacity, volume, or dimensions of anything. Legislation that adopts and mandates the use of a uniform system of weights and measures is a valid exercise of Police Power, and such laws are constitutional.
Explanation:
Answer:
2C₃H₇BO₃ + 8O₂ → 6CO₂ + 7H₂O + B₂O₃.
Explanation:
- For balancing a chemical equation, we should apply the law of conversation of mass. It states that the no. of atoms in the reactants side is equal to that of the products side.
So, the balanced equation:
<em>2C₃H₇BO₃ + 8O₂ → 6CO₂ + 7H₂O + B₂O₃.</em>
It is clear that 2.0 moles of C₃H₇BO₃ is completely burned in 8 m oles of oxygen and produce 6 moles of CO₂, 7 moles of H₂O and 1 mole of B₂O₃.
