1. What happens when you add buttermilk (an acid) to baking soda (a base) in a mixing bowl does the pH increases or decreases or
Brums [2.3K]

Answer:

Explanation:

1)This reaction is an acid base reaction. Baking soda is made up of sodium bicarbonate has it's PH above 7,while the Buttermilk contains some fatty acids with it's PH below 7, neutralization would occur when mixed together, and the pH of the mixture must be close to 7 which is neutral pH.

2) PH of 7(Neutral PH)

3)Self-raising flour has baking powder as one of its constituents. It also cotains cream of tartar, bicarbonate soda as well as calcium aluminium phosphate, the carbon dioxide from Bicarbonate of soda is released when reaction with acid takes place, then the Cream of tartar turns to tartaric acid when it is mosturized , then the reaction between them will produce bubbles of carbon dioxide in the cake, causing the cake to rise.

4)It makes a good household cleaner because it react with organic chemicals such as oil or grease then break them down like without attacking the metals that is attached to them.Bases contain particles called hydroxide ions. The higher the amount of hydroxide ions present in a base , the stronger it is.

5) The harsh acid or bike in the stomach creates a burning sensation in the back of your throat which irritate the food pipe line. Ifthe acid reflux is severe, it's reffered to as gastroesophageal reflux

Determine the oxidation states of the elements in the compounds listed. None of the oxygen-containing compounds are peroxides or
natka813 [3]

Answer:

Explanation:

You need to remember that the oxidation number of H is +1, except when it is in a metal hydrites like NaH, where its oxidation number is -1. Then, the oxidation number of O is -2, but in peroxides is -1. So with these rules you just have to multiply the ox. number with the name of atoms and all the elements in the reaction must sum 0.

What atomic or hybrid orbitals make up the sigma bond between ge and h in germanium hydride, geh4 ?
ozzi
<span>Germane is the chemical compound with the formula GeH₄, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium.


</span>In chemistry, sigma bonds (σ bonds) are the strongest type of covalent chemical bond. They are formed by head-on overlapping between atomic orbitals. Sigma<span> bonding is most simply defined for diatomic molecules using the language and tools of symmetry groups.

As the [H+] in a solution decreases, what happens to the [OH–]? A. It increases and the pH increases. B. It increases and the pH
AleksAgata [21]
<h3><u>Answer;</u></h3>

D. It decreases and the pH increases.

<h3><u>Explanation;</u></h3>
  • pH is a measure of the hydorgen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH.
  • <em><u>[H+] and [OH-] are inversely related. Therefore; As the concentration of H+ increases the pH decreases. Since the concentrations of H+ and OH- are inversely proportional, as one goes up, the other goes down. </u></em>
  • <em><u>Therefore, an increase in OH- concentration will correspond to an increase in pH and a decrease in the concentration of H+.</u></em>
