Chlorine is a halogen and is very reactive and unstable. If released in an elemental form (Cl2), it would react with other substances immediately. However, <span>chlorofluorocarbons (CFCs) which contain chlorine are unreactive and when released they eventually end up in the upper atmosphere still "intact". In the upper atmosphere, sunlight is more intense and is able to break apart CFC, releasing the highly reactive chlorine which in turns destroys ozone which is more abundant in the upper atmosphere (stratosphere). </span>
Explanation:
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. ... Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. They are also used in pesticides.
Grass planting, laying of straw , putting up sediment fenced or knee high black fabric fences can help reduce no point source water pollution
To determine the k for the second condition, we use the Arrhenius equation which relates the rates of reaction at different temperatures. We do as follows:
ln k1/k2 = E / R (1/T2 - 1/T1) where E is the activation energy and R universal gas constant.
ln 1.80x10^-2 / k2 = 80000 / 8.314 ( 1/723.15 - 1/593.15)
k2 = 0.3325 L / mol-s
1. No two elements have the same kind of atom.
Explanation:
The correct of all statement is that no two elements have the same kind of atoms.
Every element have different atoms.
- Over a hundred elements have been identified by scientists.
- Atoms are the smallest particles that takes part in chemical reactions.
- Elements are distinct substances that cannot be split.
- Atoms of all elements do not have the same mass and volume. Isotopes are examples.
- It is true that atoms of all elements have different masses and also different volumes.
- The volume of an atom is function of the number of electrons it contains.
