Explanation:
Neutralization reaction is a type of chemical reaction in which an acid and a base react together to form a salt <u><em>and water</em> </u>as products.
Combining 0.381 mol of fe203 with excess carbon produced 17.4g of fe.
Answer:
Gas particles are in a constant state of the random motion and move in straight lines until they collide with another body. The collisions exhibited by gas particles are completely elastic; when the two molecules collide, total kinetic energy is conserved.

Answer:
All elements are neutral
Explanation:
The plum pudding model of the atom indicated that all elements are neutral. The model was proposed by J.J Thomson after he conducted his experiment on the gas discharge tube.
From the experiment he discovered electrons which he called cathode rays.
Therefore, he suggested the plum pudding model of the atom.
The model describes negatively charge sphere surrounded by positive charges to balance them.
Answer:
1.5L of NaNO3 must be present
Explanation:
<em>That contains 200g of sodium nitrate. Round to 2 significant digits</em>
To solve this question we need to convert the mass of NaNO3 to moles using its molar mass (85g/mol). With the moles and the molar concentration we can find the volume in liters of the solution:
<em>Moles NaNO3:</em>
200g * (1mol / 85g) = 2.353 moles NaNO3
<em>Volume:</em>
2.353 moles NaNO3 * (1L / 1.60moles) =
<h3>1.5L of NaNO3 must be present</h3>
