During the naval battles of the South Pacific in World War II, the U.S. Navy produced smoke screens by spraying titanium tetrach
hammer [34]

Explanation:

The reaction given is;

TiCl4 + H2O --> TiO2 + HCl

The reaction is not balanced, upon balancing it is given as;

TiCl4 + 2H2O → TiO2 + 4HCl  

a. How many moles of H2O are needed to react with 6.50 moles of TiCl4?

From the reaction;

1 mol of TiCl4 requires 2 mol of H2O

6.50 mol of TiCl4 would require x mol of H2O

1 = 2

6.5 = x

x = 6.5 * 2 / 1 = 13.0 mol

b. How many moles of HCl are formed when 8.44 moles of TiCl4 react?

From the equation of the reaction;

1 mol of TiCl4 reacts to form 4 mol of HCl

8.44 mol of TiCl4 reacts to form x mol of HCl

1 = 4

8.44 = x

x = 8.44 * 4 / 1 = 33.76 mol

Which of these reactions successfully models a nuclear fission reaction?
user100 [1]

Answer:

OPTION B

Explanation:

Nuclear "fission" is the breakdown of the nucleus of a radioactive element into two or more nuclei accompanied by the release of energy. I guess that pretty much explains it.

The concentration of hydronium ions is greater than 1 × 10–7 for basic solutions. True False
Nataly [62]

Answer : The given statement is, false.

Explanation :

Ionic product of water : It is defined as the product of the concentration of hydrogen ion and the concentration of hydroxide ion.

The mathematical expression will be,

[H^+][OH^-]=10^{-14}

When the concentration of hydrogen ion and hydroxide ion are equal then the solution is neutral and the value will be, 1\times 10^{-7}. And the pH of the solution is, 7.

When the concentration of hydrogen ion is greater than 1\times 10^{-7} then the solution is acidic in nature. And the pH of the solution is, less than 7.

When the concentration of hydrogen ion is less than 1\times 10^{-7} then the solution is basic in nature. And the pH of the solution is, greater than 7.

Hence, the given statement is false.

The electrons between atoms in metallic bonds
fgiga [73]

Answer:

Metallic bonding is the type of chemical bonding that occurs between atoms of metals. In a metallic bond, atoms share their electrons in a way that allows them to form a “sea” of free electrons. This electron sea is responsible for the unique physical and electrical properties of metals.
