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

Silver chloride is virtually insoluble in water so that the reaction appears to go to completion. How many grams of solid NaCl m

masya89 [10]

Answer:

0.535 g

Explanation:

The reaction that takes place is:

NaCl + AgNO₃ → AgCl + NaNO₃

First we calculate how many AgNO₃ moles are there in 25.0 mL of a 0.366 M solution, using the definition of molarity:

Molarity = moles / liters

moles = Molarity * liters

Converting 25.0 mL to L ⇒ 25.0 / 1000 = 0.025 L

moles = 0.366 M * 0.025 L = 0.00915 mol AgNO₃

Then we convert AgNO₃ moles into NaCl moles:

0.00915 mol AgNO₃ * $\frac{1molNaCl}{1molAgNO_3}$ = 0.00915 mol NaCl

Finally we convert NaCl moles into grams, using its molar mass:

0.00915 mol NaCl * 58.44 g/mol = 0.535 g

Iron crystallizes in a body-centered cubic unit cell. The edge length of this cell is 287 pm. Calculate the density of iron in g

Jlenok [28]

Answer:

Density = 7.87 grams per mL

Explanation:

Density is given by the formula:

$d=\frac{Z\times M}{a^{3}\times N_a}$

where

Z = effective number of atoms in one unit cell.

M = Molecular mass of the substance

a = edge length of unit cell

Na = Avogadro number = 6.022×10²³

In this case:

Z=2 as it is body-centered type unit cell

M = 56 g per mole for iron

a = 287 pm = $287\times10^{-10}\ cm$

Substituting the above values in the density formula we get:

$d=\frac{2\times56}{(287\times10^{-10})^{3}\times6.022\times10^{23}}=7.87\ g\ per\ ml$

Density of iron is 7.87 grams per mL.
