Answer:
The positive particles were deflected due the concentrated positive charge of the atom
Explanation:
Rutherford concluded that the positive particles were deflected through an angle greater than 90 due to electrostatic force of repulsion between the particles and positive part of the atom.
Answer:
Phosphorus Mineralization
Explanation:
Organisms are bound to die when they do, they undergo decomposition which breaks down complex organic matter into simpler organic matter. The simpler organic matter also undergoes other processes that result in the production of simple inorganic matter; One of such processes is Phosphorus mineralization, it is the process by which phosphorus contained in organic matter is converted to simple inorganic phosphates.
Because the sun is the most important thing in this world, we live because of it and we need to understand other ones
Answer:
Ca(OH)2 + HNO3 = Ca(NO3)2 + H2O | Chemical reaction and equation.
<h3>Answer:</h3>
337 g of Solid PbI₂
<h3>Solution:</h3>
When Potassium Iodide (KI) is reacted with Lead (II) Nitrate it produces a yellow precipitates of Lead (II) Iodide (PbI₂) as expressed in following balanced equation.
Pb(NO₃)₂ + 2 KI → K₂(NO₃)₂ + PbI₂
According to this equation,
332 g (2 mol) of KI reacts to produce = 461 g (1 mol) of solid PbI₂
So,
242.36 g of KI will produce = X g of solid PbI₂
Solving for X,
X = (242.36 g × 461 g) ÷ 332 g
X = 336.53 g of Solid PbI₂
Rounded to three significant figures,
X = 337 g of Solid PbI₂
