Tensional Stress<span>. Tensional </span>stress<span>, sometimes known as extensional </span>stress<span>, stretches and pulls rocks apart. This </span>type of stress<span> occurs along </span>divergent plate boundaries<span>, where </span>two tectonic plates<span> are tearing away from one another.</span>
Divide the number of molecules you have by, 6.022 x 10^23. This will give you the moles of water, or the moles of anything, since there is always 6.022 x 10^23 molecules in 1 mole of substance.
1.23x10^24 atoms/6.022x10^23 atom/mole = 2.04 mole H20
Clean Water Act
Explanation:
The Clean Water Act in 1972 was a set of laws signed by former President Nixon that helps to keep water clean in the United States.
- The act sets a safe limit for the amount and kind of pollutants that can be released into the water that won't contaminate it.
- The acts charged the Environmental Protection Agency(EPA) to set a safe limit for nature and amount of pollutants that can be released into the water.
- This act is one of the several environmental polices in the United States that ensures a safe drinking water is available.

(a) The sun undergoes fusion while the earth undergoes fission.
The electron-dot formula of the hydrogen chloride HCl is shown in the attached diagram below.
<h3>What is the lewis electron dot diagram?</h3>
A lewis electron dot structure can be used to express the number of bonds, the bonding atoms, and the lone pairs remaining in the atoms in the molecule.
Lines are represented between atoms that are bonded with each other and excess electrons or lone pairs are shown as dot pairs and are placed next to the atoms.
As the valence electrons in the chlorine atom are equal to 7 from the electronic configuration of the chlorine atom. First, the total number of valence electrons in the HCl molecule is 7 + 1 = 8.
A chlorine atom requires only one electron to complete its octet configuration. As the octet completes, the rest of the electrons of Cl are assigned as the lone pairs of the Cl atom. Therefore, the chlorine atom has 3 lone pairs of electrons on it and the hydrogen atom completes its duplet.
