Answer:
Solid/freezing
Explanation:
Solid has the least energy of all of the phase changes and the more energy is lost the colder its gets then water turns into a solid called ice hope i helped!
Answer:
Silver has to give up one electron.
Explanation:
Silver is a transition element and has a partially filled 4d- orbital having 9 electrons and a 5s orbital having 2 electrons in it. In order to achieve stability, silver must have completely filled d-orbital having a maximum number of 10 electrons in it.
Therefore, one electron from 5s orbital jumps to 4d orbital to make it stable. Now, 5s orbital has only one electron, and it will be easy for silver to lose this electron to attain a stable electronic configuration.
Answer:
B.)
Explanation:
An Aquifer is an underground formation containing groundwater
Answer:
Explanation:
The question states that the chemical equations should be balanced and the phases should also be indicated. The abbreviations of the phases have been indicated in the question with
i) (s) meaning the compound is in solid
ii) (aq) meaning the compound is in aqueous form
iii) (l) meaning the compound is in liquid
iv) (g) meaning the compound is in gaseous form
Balanced chemical equation is that in which the number of individual atoms on the reactant side is equivalent to the number of the same individual atoms on the product side.
Only the answer (the balanced chemical equations) will be written below.
A) This reaction is balanced
Mg(s) + Br₂(l) ⇒ MgBr₂(s)
B) P₄(s) + 5O₂(g) ⇒ P₄O₁₀ (s)
C) Ba(OH)₂(aq) + 2HNO₃(aq) ⇒ Ba(NO₃)₂(aq) + 2H₂O
D) Cr₂O₃(s) + 3C(s) ⇒ 2Cr(s) + 3CO(g)
