Answer:

The lower the temperature, the lower the pressure inside of the sphere. If the exact values were plotted out, a linear relationship would be apparent. Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.

Answer:

$HCl conc=2.2M$

Explanation:

From the question we are told that:

Mass of zinc $Mass_{z_n}=2.5g$

Initial conc of HCl $HConc_1=6.0M$

Initial volume of HCl $Hvol_1=20.0mL$

Molar mass of zinc $M_{Z_n}=65.38g/mol$

Generally the equation for reaction is mathematically given by

$2HCL+Zn\implies ZnCl_2 +H_2$

Generally the equation for moles of zinc $m_{z_n}$ is mathematically given by

$m_{z_n}=\frac{Mass_{Z_n}}{M_{Z_n}}$

$m_{z_n}=\frac{2.5g}{M_{65.38}}$

$m_{z_n}=0.038molZn$

Generally the equation for moles of $m_{HCl}$ is mathematically given by

$m_{HCl}=HConc_1*Hvol_1$

$m_{HCl}=6.0M*20.0mL$

$m_{HCl}=6.0M*20.0*10^{-3}L$

$m_{HCl}=0.12\ mol\ HCl$

Generally the reacted moles of HCl $HCl_[reacted]$ is mathematically given by

Since

Zn:HCl =1:2

Therefore

$HCl_[reacted]=0.038*\frac{2}{1}$

$HCl_[reacted]=0.076mol \ HCl$

Generally the moles of HCl after Zn oxidization X is mathematically given by

$x=0.12-0.076$

$x=0.044 mol HCl$

Generally the conc of hydrochloride acid X is mathematically given by

$X=\frac{0.044}{0.020}$

$X=2.2 M Hcl$

Therefore Conc of HCl

$HCl conc=2.2M$

Independent Assessment 1 Directions: Choose the correct concept about the occurrence of an earthquake and a volcanic eruption. W

Julli [10]

Volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.

<h3>How volcanoes and earthquake occur?</h3>

Both volcanoes and earthquakes occur due to movement of the Earth's tectonic plates. They both occurs due to the heat and energy that is releasing from the Earth's core. Earthquakes can increase or fastens the volcanic eruptions through severe movement of tectonic plates.

Volcanoes eruption occurs when molten rock called magma rises to the surface. Magma is formed when the earth's mantle part melts due to higher temperature.

So we can conclude that volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.

1. If 3.00g of ammonia reacts with 40.00g of oxygen, what is the theoretical yield of nitrogen monoxide?

Sergio039 [100]

Answer:

The theoretical yield of nitrogen monoxide = 5.28 grams

Explanation:

Step 1: Data given

Mass of ammonia = 3.00 grams

Molar mass NH3 = 17.03 g/mol

mass of oxygen = 40.00 grams

Molar mass O2 = 32.0 g/mol

Step 2: The balanced equation

4NH3 + 5O2 → 4NO + 6H2O

Step 3: Calculate moles

Moles = mass / molar mass

Moles NH3 = 3.00 grams / 17.02 g/mol

Moles NH3 = 0.176 moles

Moles O2 = 40.00 grams / 32.0 g/mol

Moles O2 = 1.25 moles

Step 4: Calculate limiting reactant

For 4 moles NH3 we need 5 moles O2 to produce 4 moles NO and 6 moles H2O

NH3 is the limiting reactant. It will completely be consumed (0.176 moles)

O2 is in excess. There will react 5/4 * 0.176 = 0.220 moles

There will remain 1.25 - 0.22 = 1.03 moles

Step 5: Calculate moles NO

For 4 moles NH3 we need 5 moles O2 to produce 4 moles NO and 6 moles H2O

For 0.176 moles NH3 we'll have 0.176 moles NO

Step 6: Calculate theoretical yield of NO

Mass NO = moles NO * molar mass NO

Mass NO = 0.176 moles * 30.01 g/mol

Mass NO = 5.28 grams

Step 7: Calculate percent yield

% yield = (10.00 grams / 5.28 grams) *100 %

% yield = 189 %

⇒ Since the theoretical yield is less than 10.0 grams. I think the data are not correct ( may be 30.00 grams of NH3)
