We use a solution, such as a cabbage ph indicator, to measure the ph of household items :
- to test the safety of water
- to make sure conditions are safe
<h3>Cabbage ph indicator:</h3>
Anthocyanin, a water-soluble pigment found in red cabbage, can change color when combined with an acid or a basic. The color changes to red in situations with a pH under 7, and to bluish-green in alkaline (basic) environments with a pH above 7. Cabbage isn't known to cause acid reflux, but plenty of other common foods are.
Anthocyanin turns pink when it interacts with the hydronium ions in an acid, and blue or green when it interacts with the hydroxide ions in a base. Because it may inform us if a substance is acidic or basic by changing color, cabbage juice is referred to as a pH indicator.

Answer:
QED, EDQ, DQE, EQD, DEQ, QDE
Explanation:
The structure of all possible peptides that contain the given amino acids are :
QED, EDQ, DQE, EQD, DEQ, QDE
where : Asp is represented by the letter code D
Glu is represented by the letter code E
Gln is represented by the letter code Q
Note : when three amino acids combine they form what is known as tripeptide ( i.e. contains two peptide linkages ) while a peptide linkage is been formed by the combination of a carboxyl group of an amino acid and the amino group of different amino acid
Answer:
If I'm not mistaken the horizontal rows are periods and the vertical columns are familes.
Explanation:
Explanation:
Given parameters:
Mass of He = 5.5g
Mass of Ne = 15g
Mass of Kr = 35g
Pressure at STP = 1atm
Unknown:
Partial pressure per gas = ?
Solution:
Partial pressure is the pressure a gas would exert it alone occupies the container.
Partial pressure of a gas = Mole fraction of a gas x Total pressure of mixture
Number of moles = 
Number of moles of He = 
= 1.375mole
Number of moles of Ne = 
= 0.75mole
Number of moles of Kr = 
= 0.42mole
Sum total of moles = 1.375 + 0.75 + 0.42 = 2.54moles
Partial pressure of He = 
x 1atm = 0.54atm
Partial pressure of Ne = 
x 1atm = 0.29atm
Partial pressure of kr = 
x 1atm = 0.17atm
