Answer:
1. AgNO₃ (aq) + NaCl (aq) ----> NaNO₃ (aq) + AgCl (s)
2. Li₂SO₄ (aq) + BaCl₂ (aq) ----> 2 LiCl (aq) + BaSO₄ (s)
3. 2 NaOH (aq) + MgCl₂ (aq) ----> 2 NaCl (aq) + Mg(OH)₂ (s)
Explanation:
The reaction involving the mixing of two soluble solutions to produce a precipitate is known as a precipitation reaction.
A precipitation reaction is double-replacement reaction (a reaction that exchanges the cations or the anions of two ionic compounds) in which one product is a solid precipitate.
Precipitation reactions at useful in the identification of various ions present in a solution. In order to predict the reactions that will produce a precipitate, solubility rules as given in the solubility table below can be used.
From the tables, the reactions that will produce a precipitate, as well as their balanced molecular equations are as follows:
1. AgNO₃ (aq) + NaCl (aq) ----> NaNO₃ (aq) + AgCl (s)
2. Li₂SO₄ (aq) + BaCl₂ (aq) ----> 2 LiCl (aq) + BaSO₄ (s)
3. 2 NaOH (aq) + MgCl₂ (aq) ----> 2 NaCl (aq) + Mg(OH)₂ (s)
As you go down a group, the atoms get bigger. The bigger the atom, the more unstable it is. The more unstable it is, the more reactive the atom will be. So, as you go down a group, the nonmetals will become more reactive.
Answer: The density of the object will be 
g/ml.
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of object = 7.95 grams
Volume of water displaced = volume of the object = (95.2 - 15.5) ml =79.7 ml
Putting in the values we get:
Thus density of the object will be g/ml
Answer:
Carbon < Lithium < Beryllium < Oxygen < Fluorine
Explanation:
A) The bond that will be formed by these elements is : <u>Ionic Bond </u>
B) Group 1 elements Gives up its electron to Group 17 elements
<h3><u /></h3><h3><u>Electronegativity values </u></h3>
From the electronegativity values given in the question group 17 elements with an electronegativity value of 2.99 are more electronegative than group 1 elements with a value of 0.84. Therefore they accept electron transfer from group 1 elements.
The acceptance of electrons from group 17 elements leads to formation of an ionic bond between group 1 and group 17.
Hence we can conclude that the bond that will be formed by these elements is Ionic bond and Group 1 elements gives up its electron to group 17 elements.
