Moles of
= 6.5 mol
mole ratio of <span>
: HCl = 1 : 2
</span>∴ since <span>
cntain 6.5 mol, then HCL contains (2 * 6.5) mol
Thus moles of HCl = 13.0 </span><span>mol
Volume of HCl needed = </span>
=
<span>
</span><span> = 8.67 </span>
<span>then volume of HCL needed = 8.67 L
</span>
The answer is d. isotopes. The same element must have the same protons. And the atoms with same protons and different neutrons are called isotopes.
When red litmus turns blue, means the solution is basic, so it has more OH⁻ (hydroxide) ions.
Answer:
The correct answer is B. A compound that is a hydrogen ion acceptor in an acid-base reaction
The image on the left has been split in half to reveal the five spherical nodes that make up the 5s orbital. The nodal structure of the 5s-orbital is seen in the shape on the right. The higher s-orbitals ( 6s and 7s), while still spherical, are more complicated since they feature more spherical nodes.
