Answer:
Half-life time is 6s
Explanation:
A first order reaction follows the formula:
ln[A] = ln[A]₀ - kt
Thus, the graph of ln[A] vs t will have as slope -k.
Graphing the given values you will obtain the linear formula:
y = -0.1154x + 0.1994
R² = 0.9997
Thus, slope is -0.1154s⁻¹ and k is:
-k = -0.1154s⁻¹; <em>k = 0.1154</em>s⁻¹
Now, as half-life in a first order reaction is:
<em>Half-life time is 6s</em>
Answer: Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.

Monosodium glutamate (msg) in soup, iodine in table salt, and beet extract in strawberry ice cream are all examples of additives.
Food additives are substances that are usually added to enhance the flavor, appearance or stability of packaged/non-packaged foods. They can be derived from plant or animal sources or synthetically produced. These additives usually undergo safety assessments by the World health Organization (WHO) before it is approved for consumption.
