The balanced equation with the reaction-quotient expression is;

U(s) + 3F₂(g) → UF₆(g)

<h2>Further Explanation:</h2><h3>Chemical equations  </h3>
  • Chemical equations are equations showing reactions between reactants to form products.
  • Chemical equations show the reactants or starting substances and products or substances formed during the reaction.
<h3>Law of conservation of mass  </h3>
  • The law of conservation requires that when writing chemical equations, the mass of the reactants should be equal; to the mass of the products.
  • This is done by making sure the number of atoms of each element involved in the chemical equation is equal on both sides of the equation.
  • To ensure the law of conservation in chemical equations is observed we balance chemical equations.
<h3>Balancing chemical equation:</h3>
  • Balancing chemical equations is a try and error method that ensures the number of atoms in the side of the reactants is equal to the number of atoms in the side of products.
  • Balancing chemical equations may also require inclusion of state symbols which shows the state of each compound or element involved in the chemical reactions.
  • For example; the equation; U(s) + 3F₂(g) → UF₆(g) is balanced as the number of Uranium and Fluoride atoms are equal on both sides of the equation.

The equation presented above is that of uranium reacting with fluorine forming uranium fluoride. 

The chemical reaction can be balanced by carefully studying the equation and balancing the number of atoms of each of the element in both sides of the chemical reaction. That is,
 
                  <em>         U(s) + 3F₂(g) --> UF₆(g)</em>

Answer:

Explanation:

   The nitrates of Bi,Sn and Cd is ruled out because their sulfides are insoluble in acidic medium.

Nitrates of Ni or Co may be present because their sulfides are insoluble in basic medium. The presence of other nitrates are ruled out.

What identifies a flaw in J. J. Thomson’s model of the atom?
katrin [286]

Answer:

The plum-pudding model did not identify a central nucleus as the source of a positive charge.

Explanation:

Sir Joseph John Thomson, most popularly known as J J Thomson. He was a famous scientist who was awarded the Noble prize for Physics for his discovery of the subatomic particle, electron.

He placed his famous model of an atom which is known as plum pudding model. He proposed that the atoms are described as the negative particles that is floating within a soup of the diffuse positive charge.

But the main defect of his proposal was that it did not recognized the presence of a central nucleus as a positive charged source.

In boyle's law, the initial volume of a gas is 120 ml at 256 kpa. what will be the volume if the pressure increases to 385 kpa?
Vinil7 [7]
<h3>Answer:</h3>

79.8 ml

<h3>Explanation:</h3>

Boyle's law describes the relationship between pressure and volume when the temperature is constant. For this question, I will be rounding to significant figures.

Boyle's Formula

When describing the relationship between pressure and volume, the formula \displaystyle P_{1} V_{1}= P_{2} V_{2}. In this formula, P_{1}V_{1} is the initial pressure and volume. On the other side, P_{2} V_{2} is final pressure and volume. So, to find a missing variable you must plug in the values you are given.

Final Volume

Remember when solving this question to remain constant in your units. When we plug in the values we know we are given:

  • 256kPa*120mL=385kPa*V_{2} mL

Now, we can multiply the left side

  • 30720kPa*mL=385kPa*V_{2} mL

Finally, we can divide by 385 to isolate the final volume

  • 79.8mL=V_{2}

This gives the final volume of 79.8mL.
