The balanced chemical equation is :
LiBr (aq) + H2O (l) → LiOH (aq) + HBr (aq) .
<h3>Explain the balanced chemical equation?</h3>
- To balance a chemical equation, add coefficients to the symbols or formulas as needed so that the same number of each type of atom occurs in both reactants and products.
- There is a strategy that can help you balance equations faster. It is known as balancing by inspection. Essentially, you take the number of atoms on each side of the equation and add coefficients to the molecules to balance out the number of atoms.
- Lithium bromide, abbreviated LiBr, is a chemical compound. It is water, alcohol, and ether soluble. It is made by reacting hydrobromic acid with lithium hydroxide.

Answer:
C.
Explanation:
The heat island effect or the the urban heat island effect, is where the temperature of an area is higher than close rural areas. This is because materials suh and concrete and asphalt absorb the sunlight and store it, causing extreme weather.
Answer:
d = 3 g/cm³
Explanation:
Given data:
Mass of stone = 27 g
Volume of water = 10 cm³
Volume of water+ stone = 19 cm³
Volume of stone = ?
Density of stone = ?
Solution:
Volume of stone = total volume - volume of water
Volume of stone = 19 cm³ - 10 cm³
Volume of stone = 9 cm³
Density of stone:
d = m/v
d = 27 g/ 9 cm³
d = 3 g/cm³
