Answer:
20x-12 and -12x+21
Step-by-step explanation:
Answer: Trigonal planar 120
Step-by-step explanation:
The double bond unit and the two single bonds arrange themselves as far apart as possible in a trigonal planar arrangement. The oxynitrogen ion which is poly atomic is distinctly strange. and there isn't any simple way of working out its shape.
I think you forgot to put the pictures-
806 - 44 = 762.
762 divided by 2 = 381.
381 + 44 = 425. Hope it helps! :)
Answer:
Density = 1.042 grams /cm^3
Step-by-step explanation:
Work out the mass of each of three in a unit volume (cm^3)
Givens
- Apple Juice = 1.04 grams / cm^3
- Fruit Syrup = 1.6 grams / cm^3
- Sparkling water = 0.99 grams / cm^3
Mixture
35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams
25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 = 40 grams
270 cm^3 water = 0.99 * 270 267.3 grams
Total Mixture
- Volume = 25 + 35 + 270 = 330 cm^3
- Mass = 36.4 + 40 + 267.3 = 343.7 grams
Density
Density = mass / volume = 343.7 / 330 = 1.0415
Answer
1.042 grams / cm^3
