54 mL Ba(OH)2x(0.101 mol Ba(OH)2/1000 mL) x (2 mol OH-/ 1 mol Ba(OH)2 )  = 0.0109 mol OH-

                                 

0.0109 mol OH-x (1mol HCl/ 1 mol OH- ) = 0.0109 mol HCl

                                                     

0.109 mol HCl/(0.130 mol/L HCl) =  0.0839 L HCl

0.0839 L HCl * 1000mL = 83.9 mL of 0.130 M HCl

Vaselesa [24]

Answer:

OH−(aq), and H+(aq)

Explanation:

Redox reactions may occur in acidic or basic environments. Usually, if a reaction occurs in an acidic environment, hydrogen ions are shown as being part of the reaction system. For instance, in the reduction of the permanganate ion;

MnO4^-(aq) + 8H^+(aq) +5e-------> Mn^2+(aq) + 4H2O(l)

The appearance of hydrogen ion in the reaction equation implies that the process takes place under acidic reaction conditions.

For reactions that take place under basic conditions, the hydroxide ion is part of the reaction equation.

Hence hydrogen ion and hydroxide ion are included in redox reaction half equations depending on the conditions of the reaction whether acidic or basic.

The theory of plate tectonics is supported
frutty [35]
Alfred Wegner was the first person to propose the idea that all seven continents were all one supercontinent called "Pangea". Everyone considered his theory to be a joke until he found evidence to back up his theory. His evidence was the matching mountain ranges, fossils, certain species, and more over different continents. Also that all the seven continents fit together like puzzle pieces. I hope this helps! :)

Which isotope in each pair is more stable? Why?(d) ¹⁴₇N or ¹⁸₇N
quester [9]

<u>¹⁴₇N</u><u> </u>is the more stable isotope

<h3>Briefly explained</h3>

We have ¹⁴₇N which has a neutron to proton ratio of one, and we look at ¹⁸₇N which has a neutron to proton ratio of 1.57 Again, you look at table 24 to and you see the atomic number of seven and there is really no stable isotope. It has any more than 10 neutrons.

When we have eight, protons will go down seven protons. There's really nothing stable that has more than maybe eight neutrons. So the fact that we have 11 neutrons with ¹⁸₇N suggests that this is very unstable and

¹⁴₇N is the stable isotope of the pair.

<h3>Stable and Unstable Nuclei</h3>

An atom is electrically neutral. It contains an equal number of positively charged protons and negatively charged electrons and their charges balance. The nucleus however contains only positively charged protons which are closely packed together in a very small volume (remember neutrons have no charge).

From the laws of physics (Coulomb’s Law) one would expect that the protons being of the same charge and so close together would exert strong repulsive forces on each other. The combined gravitational force from the protons and neutrons in a nucleus is insignificant as an attractive force because their masses are so tiny.

This implies there must be an additional attractive force similar in size to the electrostatic repulsion which holds the nucleus together.
