Use the following reaction:

metallic bonds are responsible for many properties of metals, such as conductivity. why is this possible?(1 point)

USPshnik [31]

Answer and Explanation:

<em>Metallic bonding occurs between two or the same metals. In a metallic bonding structure, there is an electrostatic attraction between the positive metal ions leaving a sea of delocalised electrons. The sea of delocalised electrons allows metals to conduct electricity because the delocalised electrons are free to carry charge around the structure.</em>

<em>Pure metals are soft because there are layers of metal ions free to slide over each other as they are in a regular arrangement, pattern and size. </em>

<em>Alloys can be harder than pure metals because the different sizes of the atoms disturb the layers, stopping them from sliding over each other. Alloying a pure metal can let the metal become stronger and less reactive.</em>

How do i make homemade cookies without a mix

OLga [1]

<h2>ingredients:</h2>

2 ¾ cups all-purpose flour

1 teaspoon baking soda

½ teaspoon baking powder

1 teaspoon vanilla extract

Explanation:

Step 1

Preheat oven to 375 degrees F (190 degrees C). In a small bowl, stir together flour, baking soda, and baking powder. Set aside.

Step 2

In a large bowl, cream together the butter and sugar until smooth. Beat in egg and vanilla. Gradually blend in the dry ingredients. Roll rounded teaspoonfuls of dough into balls, and place onto ungreased cookie sheets.

Step 3

Bake 8 to 10 minutes in the preheated oven, or until golden. Let stand on cookie sheet two minutes before removing to cool on wire racks.

Partner Tip

Reynolds® Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

Find the hydrogen ion concentration of a saturated solution of calcium hydroxide whose ph is 13. 1

salantis [7]

The pH of the solutions is 12.67.

<h3>What is pH of a Solution?</h3>

pH is the measurement of how acidic or basic a solution is. The range of pH values is from 0 to 14. Lower pH values mean higher acidity, while higher pH means higher basicity. If the pH value is equal to 7, then the solution is neutral.

To calculate the pH of the solution, a few approaches are possible. Here, the pOH of the solution is calculated first using the molar concentration of $OH^{-1}$ ions. Because pH + pOH = 14, the pH of the solution can then be calculated by subtracting pOH from 14.
