Answer:
- c. <em>Aqueous solutions of hydrochloric acid and potassium hydroxide react to produce aqueous potassium chloride and water.</em>
Explanation:
The reaction is represented by the chemical equation
- HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)
The letters "aq" in parenthesis, next to the chemical formula of a compound, is used to indicate "aqueous" phase. It means that the compound is dissolved in water or, what is the same, it is an aqueous solution.
Hence, the choice C. is the best representation or description of the given reaction:
The <u>left side</u> or reactant side is:
HCl(aq) + KOH(aq)
↑ ↑ ↑
<em>aqueous solution of react aqueous solution of </em>
<em>hydrochloric acid with potassium hydroxide </em>
The <u>right side</u> or product side is:
KCl(aq) + H₂O(l)
↑ ↑ ↑
<em>aqueous and water</em>
<em>potassium chloride </em>
Answer:
Preparation of Bases
By the direct union of a metal with oxygen Some metals when heated in air or oxygen form the oxides of the metals. ... By the action of water or steam on some active metals Some active metals like sodium and potassium react with cold water to form hydroxides with the evolution of hydrogen gas.
Answer : option B) Gravity acting on the edges of plates and friction between the plate and the asthenosphere.
Explanation : The gravitational force acting on the edges of the tectonic plates raise a friction between the plate and the asthenosphere, which results into the motion of the tectonic plates.
Usually, the tectonic plates are found to move because of the intense heat produced from the Earth's core which causes the molten rock in the mantle layer to move and make a motion. It moves in a pattern which is called as convection cell that forms when the warm material rises, and cools, later eventually sink down producing the motion in the tectonic plates.
Coal and gasoline i know those to are my choices their might be some more
Answer:
33atoms
Explanation:
An atom is the smallest particle that can take part in a chemical reaction.
The given compound is:
3(NH₄)₂S
Here we have 3 moles of (NH₄)₂S ;
So:
Total number of atoms:
2 atoms of N
2 x 4 atoms of H
1 atom of S
Total = 2 + 8 + 1 = 11 atoms
So;
The total atom = 3 x 11 = 33atoms
