Two elements that have similar properties has silicon would be above or below silicon. they are germanium or antimony.
The system is isothermal, so we use the formula:
(delta)G = (delta)H - T (delta) S
Plugging in the given values:
(delta)G = -220 kJ/ mol - (1000K) (-0.05 kJ/mol K)
(delta)G = -170 kJ/mol
If we take a basis of 1 mol, the answer is
D. -170 kJ
Answer:
2.57 g of H₂
Solution:
The Balance Chemical Equation is as follow,
N₂ + 3 H₂ → 2 NH₃
According to Balance equation,
34.06 g (2 moles) NH₃ is produced by = 6.04 g (3 moles) of H₂
So,
14.51 g of NH₃ will be produced by = X g of H₂
Solving for X,
X = (14.51 g × 6.04 g) ÷ 34.06 g
X = 2.57 g of H₂
Nitrous Acid.
Hyponitrous acid: H2N2O2
Nitric acid: HNO3
Pernitric acid: HNO
Answer:
Net ionic equation: 2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
<h3>
Explanation:</h3>
- A chemical equation shows chemical symbols of compounds known as reactants and compounds known as products in a chemical reaction.
- The chemical equation between hydroiodic acid and chromium (II) carbonate is given by;
2HI(aq) + CrCO₃(aq) → H₂CO₃(aq) + CrI₂(s)
- The Ionic equation is an equation that shows all the ions involved in a chemical reaction.
- In this case, the ionic equation is;
2H⁺ I⁻(aq)+ Cr²⁺ CO₃²⁻(aq) → 2H⁺ CO₃²⁻(aq) + CrI₂(s)
- The net ionic equation is an equation showing only the ions that take part in the reactions. The ions that do not take part in the chemical reaction known as spectator ions are not shown when writing net ionic equations.
- Spectator ions are those ions that do not change state after the chemical reaction has taken place. In this case, hydrogen ions and carbonate ions are spectator ions.
- The net ionic equation is
2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
