Answer:
1.4 g/cm³
Step-by-step explanation:
1. Calculate the <em>volume of the block</em>
V = lwh
<em>Data:
</em>
l = 150 cm
w = 0.20 m
h = 6.0 mm
(a) Convert all units to a <em>common base
</em>
w = 0.20 m × (100 cm/1 m)
w = 20 cm
h = 6.0 mm × (1 cm/10 mm)
h = 0.6 cm
<em>Calculation:
</em>
V = lwh
V = 150 × 20 × 0.60
V = 1800 cm³
2. Calculate the <em>density
</em>
Density = mass/volume
<em>Data:
</em>
m = 2.5 kg
<em>Calculation:
</em>
m = 2.5 kg Convert to grams
m = 2.5 kg × (1000 g/1 kg)
m = 2500 g
Density = 2500 g/1800 cm³
Density = 1.4 g/cm³
Answer:
0.54 mole
Explanation:
CH3COOH CH3CH2OH CH3COOCH2CH3 H2O
Initial concentration 1.0 mole 1.0 mole 0 mole 1.0mol
Change - x - x + x + x
Equilibrium (1.0 - x) (1.0 - x) x (1.0 + x)
K = [CH3COOCH2CH3]*[H2O]/[CH3COOH]*[CH3CH2OH]
x*(1.0+x)/(1.0-x)(1.0-x) = 4.0
x+x²=4*(1-x)²
x+x² = 4(1² - 2x + x²)
x + x² = 4 - 8x + 4x²
4 - 8x + 4x²- x² - x= 0
3x² - 9x + 4 = 0
x=2.5 , x=0.54
2.5 mole of acid cannot be esterified, because there is only 1.0 mole of acid,
so answer is 0.54 mole.
Answer:
the amount of atoms and particle I think is in here is 17 that oxygen and water can hold with the amount of barium hydrogen.
Answer : The correct option is (A) Hydrogen region of the molecule.
Explanation :
As we know that the water molecule has two hydrogen atom and one oxygen atom. The hydrogen atom has partial positive charge and oxygen has partial negative charge.
In the charged plate, the negative attracts positive and positive attracts negative. So, the hydrogen atom attracted to the negative plate and the oxygen atom attracted to the positive plate.
When water molecule placed between oppositely charged metal plates which is positively charged, then the hydrogen atom which is positively charged attracted towards the negative plate.
