Answer:
building really complicated legos
Explanation:
Answer:
The volume of basketball is 7216.5 cm³.
Explanation:
Given data:
Radius of ball = 12 cm
Volume of ball = ?
Solution:
We will apply the volume formula of sphere.
V = 4/3 ×π×r³
we know that,
π = 22/7
r = 12 cm
Now we will put the values in formula.
V = 4/3 × 3.14 × (12 cm)³
V = 4/3 × 3.14 ×1728 cm³
V = 7216.5 cm³
Thus, the volume of basketball is 7216.5 cm³.
Answer:
Solutions with low pH have a sour taste.
Explanation:
Answer:
It will take the car 13.5 minutes to travel 3.5 miles.
Explanation:
(a) 
This is acid base reaction because there is no change of oxidation state on either side of the reaction.
(b) 
This is a oxidation reduction reaction because sodium in elemental state ( 0 oxidation state) oxidizes to Na⁺ in NaCl. Also H⁺ in HCl reduces to H° in H₂.
(c) 
This is a oxidation reduction reaction because magnesium in elemental state ( 0 oxidation state) oxidizes to Mg²⁺ in MgCl₂. Also Cl° in Cl₂ reduces to Cl⁻ in MgCl₂.
(d) 
This is acid base reaction because there is no change of oxidation state on either side of the reaction.
(e) 
This is a oxidation reduction reaction because phosphorous in P³⁻ in K₃P oxidizes to P⁵⁺ in K₃PO₄ and oxygen reduces.
(f) 
This is acid base reaction because there is no change of oxidation state on either side of the reaction.
