Answer:
Water (H20)
Explanation:
When an acid combine with a base, the reaction is called neutralization and it produces salt and water. This can be seen from the reaction between HCl and NaOH as shown below:
HCl + NaOH —> NaCl + H2O
From the above equation, we see clearly that salt (NaCl) and water (H2O) are the new products form.
The answer is 207.2 grams.
You know from the chemical formula that 1 mole of Cu3(PO4)2 contains 2 moles of P so you can work out how many moles of P are in 8.1 moles of Cu3(PO4)2.
<span>As for anything, 1 mole of X contains 6.022 * 10^23 of X. Multiply moles of X by Avogadro's number.</span>
Answer:
B) The shape of the molecule is determined by the valence electrons of the different atoms within a molecule repelling each other, so the atoms are as far apart as possible from any other valence shell.
Explanation:
VSEPR denotes Valence Electron Pair Repulsion.
It is one of the theories used to predict the model of a compound or molecule.
- An atom bonded by two or more other kinds of atoms as in many covalent molecules and ions have their geometry determined by the bonds around the central atom.
- The VESPR theory determines the total number of electron pairs surrounding the central atom of a specie.
- The electron pairs orients in such a way as to minimize the electrostatic repulsion between them.
False
Phase changes are physical changes and can be easily reverted by adjusting pressure or temperature.
