A eudiometer contains a 65.0 ml sample of a gas collected

Chemistry
1 answer:
SCORPION-xisa [38]4 years ago
6 0

Answer:

53.1 mL

Explanation:

Let's assume an ideal gas, and at the Standard Temperature and Pressure are equal to 273 K and 101.325 kPa.

For the ideal gas law:

P1*V1/T1 = P2*V2/T2

Where P is the pressure, V is the volume, T is temperature, 1 is the initial state and 2 the final state.

At the eudiometer, there is a mixture between the gas and the water vapor, thus, the total pressure is the sum of the partial pressure of the components. The pressure of the gas is:

P1 = 92.5 - 2.8 = 89.7 kPa

T1 = 23°C + 273 = 296 K

89.7*65/296 = 101.325*V2/273

101.325V2 = 5377.45

V2 = 53.1 mL

Which instrument below is used to measure an intensive property?
Andrei [34K]

An intensive property is the physical characteristics that have an independent magnitude. The thermometer can be used to measure the temperature. Thus, option C is correct.

<h3>What is an intensive property?</h3>

An intensive property has been constituted of the parameters that are not dependent on the size and the mass of the sample. Density, pressure, and temperature are some intensive properties.

The first image shows a weighing balance, the second shows a volumetric cylinder, and the fourth shows a ruler used to measure mass, volume, and length respectively, which are extensive properties.

Therefore, option C. thermometer measures temperature, which is an intensive property.

Which of the following is not equal to 485 L?
ELEN [110]

Answer:

4.85 * 10^4\ mL

Explanation:

Given

485 L

Required

Determine the measurement not equal to 485L

0.485\ kL

<em>From standard unit of conversion;</em>

1 KL = 1000 L

<em>Multiply both sides by 485</em>

485 * 1 KL = 485 * 1000 L

485KL = 485000L

<em>Divide both sides by 1000</em>

\frac{485KL}{1000} = \frac{485000L}{1000}

0.485KL = 485L  ---- This is equivalent

---------------------------------------------------------------------------------------------

4.85 * 10^4\ mL

<em>From standard unit of conversion;</em>

1000 mL = 1 L

<em>Multiply both sides by 485</em>

485 * 1000 mL = 1 L * 485

485000\ mL = 485\ L

Convert to standard form

4.85 * 10^5\ mL = 485\ L

Hence; 4.85 * 10^4\ mL is not equivalent to 485L

---------------------------------------------------------------------------------------------

48500 \ cL

<em>From standard unit of conversion;</em>

100 cL = 1 L

<em>Multiply both sides by 485</em>

485 * 100 cL = 1 L * 485

48500\ cL = 485\ L

Convert to standard form

4.85 * 10^4\ cL = 485\ L ---- This is equivalent

---------------------------------------------------------------------------------------------

4.85 * 10^8 \ μL

<em>From standard unit of conversion;</em>

1000000 μL = 1 L

<em>Multiply both sides by 485</em>

485 * 1000000uL  = 1 L * 485

485000000uL = 485\ L

Convert to standard form

4.85 * 10^8\ uL = 485\ L ---- This is equivalent

From the list of given options;

4.85 * 10^4\ mL is not equivalent to 485L

What mass of carbon dioxide is produced from the complete combustion of 5.30x10-3 g of methane?
pshichka [43]

Answer:

1.45 x 10⁻² g CO₂

Explanation:

To find the mass of carbon dioxide, you need to (1) convert grams CH₄ to moles CH₄ (via molar mass), then (2) convert moles CH₄ to moles CO₂ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass). The final answer should have 3 sig figs to reflect the given value (5.30 x 10⁻³ g).

Molar Mass (CH₄): 12.011 g/mol + 4(1.008 g/mol)

Molar Mass (CH₄): 16.043 g/mol

Combustion of Methane:

1 CH₄ + 2 O₂ ---> 2 H₂O + 1 CO₂

Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)

Molar Mass (CO₂): 44.007 g/mol

5.30 x 10⁻³ g CH₄          1 mole              1 mole CO₂          44.007 g
---------------------------  x  ----------------  x  ---------------------  x  -----------------  =
                                      16.043 g            1 mole CH₄            1 mole

=  0.0145 g CO₂

=  1.45 x 10⁻² g CO₂
