It is C. An increase of temperature results in an increase in kinetic energy of the molecules of the substance. For example, in a gas the molecules will move about faster.
<span>Magnetic declination is the angle between magnetic north (the direction the north end of a compass needle points) and true north. The declination is positive when the magnetic north is east of true north. The term magnetic variation is a synonym, and is more often used in navigation. Isogonic lines are where the declination has the same value</span>
Net ionic equation for
<span>HClO4(aq) + NaOH(aq) --> H2O (l) + NaClO4(aq).
</span>
for the molecular equation
<span>HClO4 (aq) + NaOH(aq) --> H2O (l) + NaClO4 (aq) </span>
<span>the ionic equation is </span>
<span>H+ + ClO4- + Na+ + OH- --> H2O(l) + Na+ + ClO4- </span>
<span>now remove the spectator ions (Na+ and ClO4-) to give the net ionic equation </span>
H+ + OH- --> H2O(l)
