Balance the equation first:
2 Fe+6 HNO3→2 Fe(NO3)3+3H2
Then calculate mass of Iron :
4.5×3.0×3.5 cm3(1 mL1 cm3)(7.87 g Fe1 ml)=371.86 g Fe
Now use Stoichiometry:
371.86 g Fe×(1 mol Fe55.85 g Fe)×(6 mol HNO32 mol Fe)=19.97 mol HNO3
Convert moles of nitric acid to grams
19.97 mol HNO3×(63.01 g HNO31 mol HNO3)=1258.3 g HNO3
To reduce a haloalkane, it has to be eliminated first. This is because 2 bromopropanes are a saturated compound that can not be reduced by a saturated compound. Dehydrohalogenation of the haloalkanes into the form of propene and hydrogen bromide can lead to the elimination. The propene is then reduced to propane.
Answer:
metallic bonding is the bond form between two or more metal elements or between metal element and the other group elements
The greater, the ionic property, the greater will be solubility. water is a covalent compound where calcium carbonate is ionic that's why the solubility of
(s) would be greater.
<h3>What is
solubility?</h3>
The capability of a substance, the solvent, to combine with another substance, the solvent, has been known as solubility. Insolubility, or just the solute's inability to create that kind of a solution, would be the opposite attribute.
<h3>How does solubility depend on the ionic compound?</h3>
Ionic chemicals dissolve readily in just about any liquid that has the ability to rupture the ionic link present in them. Since water itself has a stronger ionic bond and is still polar in nature, water disrupts the ionic link by hydrogen bonding. Several other solvents, like kerosene and gasoline, are unable to dissolve the ionic bond.
The greater, the ionic property, the greater will be solubility. water is a covalent compound where calcium carbonate is ionic that's why the solubility of
(s) would be greater in distilled water than in tap water that contains 50 mg/L of calcium ions

Answer:
44. (C) The temperature must decrease because the reaction is endothermic
45. (D) 3Pi
46. (C) It must be positive since positive since ΔG° is positive and ΔH° is positive
47. (B) The sum of the bond enthalpies of the bonds of the reactant is less than the sum of the bond enthalpies of the bonds of the products
Explanation:
Here we have
CH₃OH(g) → CO(g) + 2H₂(g) ΔH° +91 kJ/mol
44. Since the reaction is endothermic, absorbs heat, temperature must decrease because the reaction is endothermic
45. Since the number of moles in the reactant is 1 and the number of moles in the product is 3, we have;
Pressure, P is directly proportional to the number of moles
Therefore, where the pressure in the reactant is Pi pressure in the products will be 3Pi
46 Since the reaction takes place spontaneously at 600 K, therefore ΔG is negative and ΔH is positive hence ΔS must be positive
47. Since the reaction is an endothermic reaction, the sum of the bond enthalpies of the bonds of the reactant is less than the sum of the bond enthalpies of the bonds of the products.
