Answer:
This ammonium laurel sulfates anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. It means it has a hydrophilic head and hydrophobic tail. There are ammonium ions, sulfate, and fatty acids present.
Lauryl sulfate has lauric acid attach to sulfate ions with carbon-sulfur bond, the fatty acid formed by the covalent bonds between C-C attached to hydrogens. Sulfur also bound to oxygen by covalent bonds. Nitrogen is surrounded by the four hydrogen atoms in the hydrophilic head.
Answer:
4.1 moles of FeCl₃
Explanation:
The reaction expression is given as shown below:
2Fe + 3Cl₂ → 2FeCl₃
Number of moles of Cl₂ = 6.1moles
So;
We know that from the balanced reaction expression:
3 moles of Cl₂ will produce 2 moles of FeCl₃
Therefore 6.1moles of Cl₂ will produce = 4.1 moles of FeCl₃
The number of moles is 4.1 moles of FeCl₃
Answer:
Atoms will rearrange and for new substances
Explanation:
In a chemical reaction, elements combine their atoms and create new substances. For this to occur, the bonds must break and form new ones with the other atoms.
The Mohs scale is for natural minerals<span>. For manufactured products other measures of hardness are better. ... There are ten </span>minerals<span> in Mohs scale, talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and for last and</span>hardest<span>, diamond.

Answer:
atomic orbital
Explanation:
Atoms are made of three sub-atomic particles, electron, proton and neutron.
Protons and neutrons are present in the core of the atom in a very small zone called nucleus. Nucleus is positively charged.
Electrons are present around the nucleus. Electrons present outside the nucleus are also termed as electron cloud. Region outside the nucleus where probability of finding an electron is maximum is termed as atomic orbital. Four basic types of orbitals are present around the nucleus which are
s-orbital
p-orbital
d-orbital
f-orbital
Electrons present in same orbitals have same energy. Therefore, term is atomic orbital.
