I don’t know but sorryyyyyy
Answer: 2. Decomposition
Explanation:
Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.
Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.
lithium carbonate → lithium oxide + carbon dioxide
Single replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
A double replacement reaction is one in which exchange of ions take place.
A , write out and balance the reaction
Answer:
Final concentration = 0.019 M
Explanation:
Initial Concentration [A]o = 0.27M
Rate constant, k = 0.75 s^-1
Final concentration [A] = ?
Time, t = 1.5s
The relationship between the variables is given by the equation;
ln[A] = ln[A]o - kt
ln[A] = ln(0.27) - (0.75)(1.5)
ln[A] = - 1.309 - 1.125
ln[A] = - 2.434
[A] = 0.019 M
Is this multi choice or no?
