ANSWER(S):

p= 3 g/cm³

EXPLANATION(S):

density formula: p= m/V; p= p, m= 9 g, V= 3
p= (9)/(3)
p= 3

p= 3 g/cm³

Answer:

120 g SO3

Explanation:

128 g SO2 -> 160 g SO3

96 g SO2 -> x

x= (96 g SO2 * 160 g SO3)/128 g SO2

x= 120 g SO3

A student has two identical glasses of milk except that the temperature of the milk in one glass is 40ºF

kiruha [24]

80ºF.

Explanation:

At a temperature of 80ºF, the milk has the highest thermal energy.

The thermal energy in a body increases as the temperature of the body increases.

To increase the temperature of a body, heat is a supplied to it or work is done on it.

Heat is a form of thermal energy.
As the heat increases, the particles of the milk gains more kinetic energy.
This forces them to move more faster.
A body with a higher temperature has more thermal energy.

Glucose (C6H12O6)(C6H12O6) can be fermented to yield ethanol (CH3CH2OH)(CH3CH2OH) and carbon dioxide (CO2).

zhenek [66]

Answer: a) 49.8 gram

b) 47.0 %

Explanation:

First we have to calculate the moles of glucose

$\text{Moles of glucose}=\frac{\text{Mass of glucose}}{\text{Molar mass of glucose}}=\frac{97.5g}{180.15g/mole}=0.54moles$

The balanced chemical reaction will be,

$C_6H_{12}O_6\rightarrow 2CH_3CH_2OH+2CO_2$

From the balanced reaction, we conclude that

As,1 mole of glucose produce = 2 moles of ethanol

So, 0.54 moles of glucose will produce = $\frac{2}{1}\times 0.54=1.08$ mole of ethanol

Now we have to calculate the mass of ethanol produced

$\text{Mass of ethanol}=\text{Moles of ethanol}\times \text{Molar mass of ethanol}$

$\text{Mass of ethanol}=(1.08mole)\times (46.08g/mole)=49.8g$

Now we have to calculate the percent yield of ethanol

$\%\text{ yield of ethanol}=\frac{\text{Actual yield}}{\text{Theoretical yield }}\times 100=\frac{23.4g}{49.8g}\times 100=47.0\%$

Therefore, the percent yield is 47.0 %
