Answer:
2. Translucent
4. Reflection
Explanation:
The terms translucent describes the nature of the juice and reflection perfectly fits the property of the light.
A translucent substance is one that partially allows light to pass through it. Since it is said that some of the light bounced back and some passed through, this is translucent.
Also, the light bouncing back is an indicator of reflection. Reflection is a property of light where it bounces back a surface.
Answer:
not sure, but you know what?
Explanation:
you are amazing! keep doing what youre doing!
Answer:
One reason, that water did not boil at 100 C could be the atmospheric pressure
Calculate the percent error for each sample from the theoretical 100°c
Percent error ( 102C) = (102-100/ 100) *100
= 2% error
Answer:
I really hope this helped❤
Explanation:
welll, in chemistry and physics, the Avogardo constant is the number of constituent particles, usually atoms or molecules that are contained in the amount of substance given by one mole and is equal to 6.02 × 10**23. so 3 moles of carbon atoms would be 18.06 × 10**23.
Answer:
215 mL of silver nitrate are needed.
Explanation:
Let's think the reaction:
Na₂CrO₄(aq) + 2AgNO₃(aq) → Ag₂CrO₄ (s) ↓ + 2NaNO₃(aq)
First of all, we determine the moles of chromate we have available.
Molarity = mol / volume(L)
We convert volume to L → 75mL . 1L / 1000mL = 0.075 L
Molarity . volume(L) = moles → 2.50 M . 0.075L = 0.1875 moles
Ratio is 1:2. For 1 mol of chromate I need the double of moles of nitrate.
So, for 0.1875 moles of chromate I would need (0.1875 . 2) = 0.375 moles of nitrate. Let's determine volume of solution
Molarity = mol/ volume(L) → volume (L) = mol / Molarity
volume (L) = 0.375mol / 1.74M → 0.215L
We convert the value to mL → 0.215L . 1000mL/ 1L = 215 mL
