Answer:
Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.
Answer:
You multiply the elements atomic number by the number of atoms in the element in order to find its molecular mass.
Hope this helps!
Mg+2HCl-->H2+MgCl2 you would it have to make it so each is equal on each side you would add a 2 on left in front of HCl because on the other side there is already 2 H and 2Cl so just put a 2 in front of HCl
0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.
<h3>What amount in moles of hydrogen will be produced?</h3>
The amount in moles of hydrogen produced when the same quantity of electricity is passed through different electrolytes is inversely proportional to the charge on the ions.
The charge on the Lead ion is +2.
The charge on the hydrogen ion is +1.
2 atoms of hydrogen gives one molecule of hydrogen gas.
Hence, equal charge liberates equal amounts in moles of lead and hydrogen gas.
Therefore, 0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.
