Answer:
c
Explanation:
x basic and metallic while y is acidic
The study of chemicals is called chemistry.
The correct answer is B.
The compound which has oxygen in it is called oxide. According to the question, the element is react with the acid and base.
The X only reacts with the acidic compound but not basic compound hence the element X is basic in nature. while Y only reacts with the basic compound, not X, hence the Y element is acidic in nature.
Therefore, the correct answer is B.

A solution of 0.220 g of KIO3 is prepared in 50 ml volumetric flask. 2.00 mL of this solution is pipetted into a beaker with 8.00 ml distilled water, to give 10 ml of diluted KIO3. To this, 10.00 mL of starch sulfite was added. What would be the initial concentration of IO3- in this final solution
Answer:
0.00044 g/mL
Explanation:
First, 0.220 g of KIO₃ are dissolved in 50 mL, so the concentration at this point is:
0.220 g / 50 mL = 0.0044 g/mLThen 2.00 mL of this solution are added to 8.00 mL of water (final volume = 10.00 mL). We calculate the concentration of the resulting solution:
0.0044 g/mL * 2.00mL / 10.00mL = 0.00088 g/mLFinally, to this 10 mL solution, another 10.00 mL were added. Thus the KIO₃ (or IO₃⁻) concentration is:
0.00088 g/mL * 10.00mL / 20.00mL = 0.00044 g/mLAn reading of 8 on the pH scale is indicative of?
Answer:
Basic or alkaline
Explanation:
ph 7 is neutral
below 7 is acidic
above 7 is basic or alkaline
Answer:
[tex]\boxed {\boxed {\sf Weak \ base}}[/tex]
Explanation:
The pH scale which classifies a solution's acidity or basicity.
A pH below 7 is acidic. This means it has more hydrogen ions. A pH equal to 7 is neutral. This has equal hydrogen and hydroxide ions.A pH above 7 is basic. This has more hydroxide ions.We are given a reading of 8. This is above 7, but not much greater. Therefore, it could be classified as a weak base.

Nieko purchases a box of granola cereal that has a mass of 0.312 kg, then according to law of conservation of mass, the mass of each group is 0.312 kg.
What is law of conservation of mass?According to law of conservation of mass the mass in isolated system can neither be created nor destroyed by chemical reaction and physical transformation but it transfer from one form to another.
When wood burn the mass of soot, gases and ashes is equal to the original mass of charcoal and the oxygen when it first created is one of the best example of law of conservation of mass.
Thus, Nieko purchases a box of granola cereal that has a mass of 0.312 kg, then according to law of conservation of mass, the mass of each group is 0.312 kg.
