Answer:
Cu^2+ (aq) + S^2- (aq) --> CuS (s)
Explanation:
Break up all the soluble compounds into their constituent ions to get the complete ionic equation, and cross off the ones that appear the same on both sides:
Cu (aq) + 2Cl(aq) + 2Na (aq) + S (aq) --> CuS (s) + 2Na (aq) + 2Cl (aq)
2Cl and 2Na appear on both sides of the arrow, so cross those out to get the net ionic equation.
i believe the answer is Fe2(SO4)3
Answer:
what is the English translation, id like to help
Explanation:
Answer:
- <em>The kinetic energy in J of an electron moving at 6.00 × 10⁻⁶ m/s is:</em>
<em> </em><u>1.64 × 10 ⁻³⁸ J</u>
<em />
Explanation:
<u>1) Data:</u>
a) KE =?
b) v = 6.00 × 10⁻⁶ m/s.
c) m = 9.11 × 10⁻²⁸ g.
<u>2) Formula:</u>
<u>3) Solution:</u>
- KE = (1/2) = (1/2) × 9.11 × 10⁻²⁸ g × ( 6.00 × 10⁻⁶ m/s)² = 163.98 × 10 ⁻⁴⁰ J
