Answer:</h3>
Ni + Pb(NO₃)₂ → Ni(NO₃)₃ + Pb
<h3>
Explanation:</h3>
We are required to write a balanced equation from the word equation;
- Nickel reacts with lead nitrate (II) to produce nickel(III) nitrate and lead
- The equation will be written by writing the symbols of the reactants and products.
That is;
Ni + Pb(NO₃)₂ → Ni(NO₃)₃ + Pb
We then balance the equation;
- To balance the equation, we put appropriate coefficients on reactants and products, so that the number of atoms of each element is equal on both sides of the equation.
- Thus, the balanced equation will be;
2Ni + 3Pb(NO₃)₂ → 2Ni(NO₃)₃ + 3Pb
Molality is obtained by dividing the number of moles of solute by the mass in kilogram of the solvent. None of the dimensions is dependent in temperature. On the other hand, molarity is obtained by dividing the number of moles of solute by the volume in liters of the solution. Volume is temperature dependent.
Answer:
1. London dispersion
Explanation:
Sulphur trioxide ( SO₃ ) -
The chemical compound SO₃ is planar in structure , the only intermolecular forces shown by SO₃ is the London forces .
dipole - dipole is not observed in this compound , as it is not possible to generate poles between the sulfur and oxygen atom due to very less difference in the electronegativity .
Hydrogen bonding is also not observed , because there is not hydrogen atom .
Hence , only London forces are observed in SO₃ .
What I’m seeing on quizlet says what you’re describing is a ball-and-stick model.
Answer:
c. The atoms of one element can be identical to the atoms of another element.
Explanation:
<em>Which of the following is not a statement of Dalton's atomic theory of matter?</em>
<em>a. Elements are made of atoms.</em> TRUE. An atom is the smallest particle of a chemical element that can exist.
<em>b. Atoms of a given element are identical.</em> TRUE. The only slight difference is in the mass of isotopes.
<em>c. The atoms of one element can be identical to the atoms of another element.</em> FALSE. The atoms of different elements are different from one to another.
<em>d. A given compound always has the same number and kinds of atoms. </em>TRUE. This is known as Dalton's law of constant composition.
