Answer:
A bird's feathers are supposed to keep the bird warm and help them fly. A tree's bark is supposed to protect the inside of the tree.
Explanation:
If a tree has no bark, the inside of it is exposed. If a bird has no feathers, the bird is cold and cant fly.
2 are formed :) hope this helped!
Answer:
The equilibrium position will shift towards the lefthand side.
Explanation:
[CoCl4] 2- (aq) + 6H2O (l) ⇌ [Co(H2O)6] 2+ (aq) + 4 Cl- (aq)
The equation written above in exothermic as written. That is, the forward reaction is exothermic. The equilibrium position is observable by monitoring the colour change of the solution. At the left hand side, the solution is blue but at the right hand side the solution is pink. Addition of heat (in a hot water bath) will shift the equilibrium towards the left hand side, that is formation of more [CoCl4] 2- making the solution to appear blue in colour.
Answer:
False.
Explanation:
False because there's no chemicals making change. its a physical change
<span>7.86 g / 1 mL
divide g by 1000 for kg and divide mL by 100 for dL
</span>0.00786 kg / 0.01 dL = 0.786 kg/dL (density)
3.67 kg / 0.786 dL = 4.6692 dL
Another approach:
3.67kg > (3.67kg x 1000) = 3670 grams
3670 grams / 7.86 (density) = 466.92 mL
466.92 mL (divide by 100 for dl) = 4.6692 dL
