Answer:
The CN double bond and triple bond are stronger than the corresponding CC bonds
Explanation:
Answer:
0.0010 w/v %
Explanation:
Based on the reaction:
NiCl₂(aq) + 2AgNO₃(aq) → 2AgCl(s) + Ni(NO₃)₂(aq)
Finding the moles of AgCl produced we can find the moles of NiCl in the reaction medium and its mass:
<em>Moles AgCl -Molar mass: 143.32g/mol-:</em>
5.8mg = 5.8x10⁻³g * (1mol / 143.32g) = 4.047x10⁻⁵ moles AgCl
<em>Moles NiCl₂:</em>
4.047x10⁻⁵ moles AgCl * (1mol NiCl₂ / 2mol AgCl) = 2.023x10⁻⁵ moles NiCl₂
<em>Mass NiCl₂ -Molar mass: 129.60g/mol-:</em>
2.023x10⁻⁵ moles NiCl₂ * (129.60g / mol) = 2.62x10⁻³g of NiCl₂ are produced.
And the concentration in w/v% is:
2.62x10⁻³g NiCl₂ / 250mL * 100 =
<h3>0.0010 w/v %</h3>
A chemical reaction is a spontaneous reaction is determined by the Gibb's energy and enthalpy of the reaction whether it is exothermic or endothermic. The factors that apply here are heat and entropy. Gibb's energy is related to entropy. Answers are D. and E
No it does not represent an isotope. The number of neutrons changes in an isotope, not the number of electrons.
