Answer:
In order of basicity we have
1. Soda pop (Least basic Normally called acidic)
2. Orange juice
3. Milk
4. Blood (slightly basic)
5. Hand soap
6. Drain cleaner (Highly basic)
Explanation:
Orange juice; the pH of orange juice is in the 3.3 to 4.2 range
Milk; the pH of milk about 6.5 to 6.7
Blood; the blood pH is around 7.35 to 7.45
Hand soap with contents such as ammonium hydroxide is basic, its pH is about 9-10
Drain cleaner contains baking soda or sodium bicarbonate which basic with a pH of 12 to 14
Soda pop pH of soda pop is in the range of 2.34 to 3.10. It contains carbonated water with a pH of 3–4, making it mildly acidic.
Arranging the above listed in order of increasing basicity, we have
1. Soda pop
2. Orange juice
3. Milk
4. Blood
5. Hand soap
6. Drain cleaner
Answer:
hydrate
Explanation:
when a hydrate is heated,it changes color due to the exothermic reaction taking place.the structure of the complex changes but not entirely.this result in the sample to to not dissolve completely and we can observe the small traces of the sample.
3Fe + 4H2O (yields) Fe3O4 + 4H2
Answer:
C
Explanation:
Cause waves causes gravity to make higher waves
Answer:
26 grams of D will be produced.
Explanation:
The reaction is given by:
A + B -----> C + D
Mass of A reacted = 21 g
Mass of B reacted = 22 g
Mass of C formed = 17 g
Mass of D formed = m =?
According to law of conservation of mass, the total mass of the reactants used is equal to the total mass of the product formed.
Then:
mass of A reacted + mass of B reacted = mass of C formed + mass of D formed
21 + 22 = 17 + m
m = 26 g
