Answer:
Yes, yield.
Explanation:
N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation
First, find limiting reactant:
Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2
Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2
The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)
Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3
The heat energy from the fire is transferred to the pot by
- <em>radiation</em> — the hot coals radiate heat to the pot.
- <em>convection</em> — the hot gases from the fire travel upward until they reach the pot
The pot absorbs the heat energy and <em>conducts</em> the heat to the water inside.
The hot water <em>conducts</em> heat to the peas in three steps:
- warming the frozen ice and peas to 0 °C.
- thawing the ice and peas at 0 °C.
- heating the peas to 100 °C and cooking them at that temperature.
<em>Note</em>: Heat always flows spontaneously from a hotter to a cooler object.
Answer:
1. 7.256g of NaCl
2. 47.33g of Cl2
Explanation:
2 moles of Na reacts to produce 2 moles of NaCl
8 moles of Na will still produce 8 moles of NaCl
Mass of NaCl = molar mass of Nacl/moles of Nacl
=58.5/8
=7.256g of NaCl
From the equation, 2 moles of Na reacts with 1 mole of Cl2
3/2 moles of Cl2 will react with 3 moles of Na
Mass of Cl2 = 71/1.5
=47.33g of Cl2
The jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml mass of the water in the graduated cylinder is 128.5 gram.
<h3>What is density?</h3>
Density is a amount of a substance per unit area of the volume of the mass and it is the ratio of mass and the volume unit is centimeter cube.
The density of the substance = mass / volume
substituting the value in the equation,
Density = 132.6 / 48.6 = 2.1 centimeter cube.
mass = density volume
mass = 2.1 61.2
mass = 128.5 gram.
Therefore, mass of the water in the graduated cylinder is 128.5 gram if jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml.
