Answer:
The correct option is A. Lithium Iodide
Explanation:
According to the system for naming an ionic compound, the name of the metal ion is always written first and the name of the non-metal ion is written after it.
Lithium is a metal whose ion is named as lithium ion Li+ and Iodine is a non-metal whose ion name is iodide and is written as I-. The charges on metal atoms depend on the number of group they are present on, in the periodic table. The charge on the non-metal ion would be the group number minus eight. Hence, lithium iodide is the correct answer.
Answer:
The statement "The total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water." is true due to the Law of Conservation of Mass which states that matter cannot be created nor destroyed.
The rate of reaction is always expressed in concentration per time like mol/L·s. The equation is:
r [mol/L·s] = kCⁿ, where n is the order of reaction. Since k is 1300/s, that means that Cⁿ = C such that (1/s)*(mol/L) = mol/L·s. Thus, n=1. For a first order reaction, the formula would be:
ln(A/A₀) = -kt
where
A is the amount of material after time t
A₀ is the amount of material at t=0
The half life is when A/A₀ = 1/2÷1 = 1/2. Thus, the half-life t is:
ln(1/2) = (-1300t)
t = 5.33×10⁻⁴ seconds
