Yes it is a exothermic reaction.
<em>Data collected from moonquakes shows that ______;</em>
The center of the moon may be molten
<u>Convection in the molten zone makes moonquakes possible. These moonquakes are usually triggered by tidal forces coming from Earth.</u>
Answer:
Boiling Point and Melting Points
Explanation:
Depending on the material, each material will have different points of which of how high it needs to be heated to burn, melt, burn, etc.
The answer is c) Electrical energy
A balanced equation for the precipitation of barium sulfate after mixing aqueous ammonium sulfate and barium chloride is as follows:
(NH₄)₂SO₄ (aq) + BaCl₂ (aq) ------> BaSO₄(s) + 2NH₄Cl (aq)
As suggested by the equation, 1 molecule of ammonium sulfate reacts with 1 molecule of barium chloride and forms 1 molecule of barium sulfate and 1 molecule of ammonium chloride.
