Answer:

264g

Explanation:

C + O2 -> CO2

_g + _g -> 396g

396÷3=132

C (132g) + O2 (264g) -> CO2 (396g)

What problems could arise if scientists use different units to measure height

Shkiper50 [21]

Scientists can measure the height in different units but problem could arise when they compare all the measurements. That is the reason there is standard units for measurements.

<span>There may be error arises when an American scientist is measuring the height of an object in inches and other Australian scientist is measuring the height of same object in meters. Their data cannot be compared because they are using different units to measure height.</span>

A gas occupies a 1.5 L container at 25 degrees Celsius and 2.0 atm. If the gas is transferred to a 3.0 L container at the same t

harkovskaia [24]

To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

P2 = P1 x V1 / V2

P2 = 2.0 x 1.5 / 3

Draw the mechanism for the acid-catalyzed reaction of acetic acid (ethanoic acid) with the methanol to yield methyl acetate (met

timama [110]

When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now write the chemical equation

CH₃COOH + CH₃OH ⇄ CH₃COOCH₃ + H₂O

Here

CH₃COOH is Ethanoic acid (Acetic acid)

CH₃OH is Methanol (Methyl Alcohol)

CH₃COOCH₃ is Methyl ethanoate (Methyl Acetate)

H₂O is water

Thus from the above conclusion we can say that When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.

If the pressure on the surface of water in the liquid stato

Novosadov [1.4K]

The water will boil at C) 80°C

<h3>Further explanation</h3>

Given

Vapour pressure of water = 47 kPa

Required

Boiling point of water

Solution

We can use the Clausius-Clapeyron equation :

$\tt ln(\dfrac{P_1}{P_2})=\dfrac{-\Delta H_{vap}}{R}(\dfrac{1}{T_1}-\dfrac{1}{T_2})$

Vapour pressure of water at boiling point 100°C=101.325 kPa

ΔH vap for water at 100°C=40657 J/mol

R = 8.314 J/mol K

T₁=boiling point of water at 101.325 kPa = 100+273=373 K

Input given values :

$\tt ln\dfrac{101.325}{47}=\dfrac{-40657}{8.314}(\dfrac{1}{373}-\dfrac{1}{T_2})\\\\0.7682=4890.1852(\dfrac{1}{373}-\dfrac{1}{T_2})\\\\0.0001571=(\dfrac{1}{373}-\dfrac{1}{T_2})\\\\\dfrac{1}{T_2}=0.00283\rightarrow T_2=353~K=80^oC$
