The net ionic equation is as below
H^+(aq) + H^-(aq) → H2O(l)
Explanation
from the chemical equation
HClO4(aq) + NaOH (aq) → H2O(l) + NaClO4(aq)
write ionic equation
that is,
H^+(aq)+ClO4^-(aq) + Na^+(aq) +OH^-(aq)→ H2O(l) + Na^+(aq)+ClO4^-(aq)
cancel the spectator ions in both side(ions that do no take place in a chemical equation)
that ClO4^- and Na^+
the net ionic is therefore
= H^+(aq) + OH^-(aq) → H2O(l)
Answer:
20 mL OF 6 M HYDROCHLORIC ACID WILL BE NEEDED
Explanation:
M1 V1 = M2 V2
M1 = Molarity of sodium hydroxide = 3 M
V1 = volume of sodium hydroxide = 40 mL
M2 = Molarity of hydrochloric acid = 6 M
V2 = Volume of hydrochloric acid = unknown
Rearranging the equation, we have:
V2 = M1 V1 / M2
V2 = 3 * 40 mL / 6
V2 = 120 / 6
V2 = 20 mL
To precipitate the benzoic acid by 6 M of hydrochloric acid, 20 mL volume will be needed.
Answer:
yes
Explanation:
This can be fixed by multiplying the product contacting nitrogen by 2. o The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.
Five points of Dalton's atomic theory:
1) all elements are made up of atoms.
<span>2) atoms are so small that they cannot be divided any further. </span>
<span>3) an atom can neither be destroyed nor be formed. </span>
<span>4) atoms of an element are similar, they posses same mass and same properties. </span>
<span>5) atoms of different elements combine in a definite ratio to form compounds. </span>
<span>
</span><span>Due to further experimentation it was concluded that atom is made up of small particles identified as proton, neutrons, and electrons. They can be further subdivided.
Another change is the presence of isotopes of atoms of different elements. Hence, atoms of the same element can also have different masses. </span>
