The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.
Answer: Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
Explanation:
First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Carbonic acid slowly dissolves away minerals in rock, especially the carbonate minerals that make up limestone and marble. The weak acid decomposes the insoluble rock into watersoluble products that move into the groundwater.
Answer:
The rate of reaction is - 2.868 * 10^-4 M/S
Explanation:
In the following reaction: 2 NO + O2 → 2NO2
NO will be consumed, when adding O2.
This means it will disappear. This is confirmed by the concentration at 5 seconds and 650 seconds.
A = -Δ[A] / ΔT = [A2] - [A1] / T2 - T1
(0.225 - 0.04) / (650 - 5) = 0.185 / 645 = 2.868 * 10^-4 M/S
Since it will disappear, this number will be negative : - 2.868 * 10^-4 M/S
The rate of reaction is - 2.868 * 10^-4 M/S
