Explanation:
A pH helps us to determine whether a solution is basic or acidic in nature.
If pH is less than 7 then the substance or solution is acidic in nature and if pH is more than 7 then the substance or solution is basic in nature.
Also, acids are sour in taste whereas bases are bitter.
Thus, we can conclude that the bottle whose label have fallen off contains an acid and the pH of this liquid is MOST likely less than 7.
Answer:
C. Sodium hydrogen carbonate
Explanation:
IUPAC : International Union of Pure and Applied Chemistry.
According to IUPAC rules:
Baking soda is a salt formed by a cation(Positive charge) and an anion(anion).
: Is made from cation and one anion
IUPAC naming starts from the cation name .(Here the cation name is : Sodium .) The cation is named same as the name of element.
Anion is named after the cation .Here is named as Hydrogen carbonate.(anion name ends with -ate ,-ite -ide etc).
So, name of the compound is Sodium hydrogen carbonate
Note: d.Sodium hydrogen monocarbon trioxide, can't be correct answer, because it show the existence of anions of oxygen()and not )
The pressure of 2.29 atm can be converted to
<h3>What is conversation?</h3>
Conversation is a way of writing a value in another unit, it helps to reduce large values by using a unit.
It should be noted that 1 atm. =760.0 mm Hg
We were given 2.29 atm, the we can convert it to mm Hg. as;
= 1740.4 mm Hg.
Therefore, The pressure of 2.29 atm can be converted to

0.030 mol Na2S2O3
From the balanced equation, the <em>molar ratio</em> of Na2S2O3:Cl2 is 1:4.
∴ Moles of Na2S2O3 = 0.12 mol Cl2 x (1 mol Na2S2O3/4 mol Cl2)
= 0.030 mol Na2S2O3
