A chemist conducts an experiment in which 2. 00 l of hydrogen gas is collected over water at 1. 00 ATM and 298. 15 K. The phrase over water means that the gas was collected by bubbling it into an inversed bottle filled with water which is sitting in a water bath. However the gas collected is now saturated with water vapor. The partial pressure of water vapor at 298. 15 K is 0. 0 300 ATM. Using Dalton's law calculate the pressure of the hydrogen gas in ATM

Answers

Answer:According to Dalton's law of partial pressures, the total pressure is equal to the sum of the partial pressures of each gas.  In equation form, this looks like this ...

Pt = P1 + P2 + ...

Pt = total pressure

P1 = partial pressure of gas 1

P2 = partial pressure of gas 2

The haber process can be used to produce ammonia (nh3) from hydrogen gas (h2) and nitrogen gas (n2). the balanced equation for this process is shown below. 3h2 n2 right arrow. 2nh3 the molar mass of nh3 is 17.03 g/mol. the molar mass of h2 is 2.0158 g/mol. in a particular reaction, 0.575 g of nh3 forms. what is the mass, in grams, of h2 that must have reacted, to the correct number of significant figures? 0.1 grams 0.102 grams 0.10209 grams 0.1021 grams

Answers

The mass of hydrogen reacted with nitrogen to give ammonia is 0.1 grams.

How we calculate the mass from moles?

Mass of any substance will be calculated by using the moles as:

n = W/M, where

W = required mass

M = molar mass

Given chemical reaction is:

3H₂ + N₂ → 2NH₃

Moles of 0.575 g of NH₃ will be calculated as:

n = 0.575g / 17.03g/mol = 0.033 moles

From the stoichiometry of the reaction, it is clear that:

2 moles of NH₃ = produced by 3 moles of H₂

0.033 moles of NH₃ = produced by 3/2×0.033=0.0495 moles of H₂

Now we calculate the mass of hydrogen from the given moles and molar mass as:
W = (0.0495mol)(2.0158g/mol) = 0.09 grams = 0.10 grams

Hence, option (a) is correct i.e. 0.1 grams.

Jude has a 30.00 L cylinder full of acetylene gas that he will use for welding in his workshop. If the pressure of the cylinder is 1720 kPa and the workshop is at 20.0 °C, then how many moles of acetylene are in the tank? (Show work)

Answers

Answer:

About 21.2 moles.

Explanation:

Recall the ideal gas law:

[tex]\displaystyle PV = nRT[/tex]

Where P is the pressure of the gas; V is its volume; n is the number of moles of gas; R is the universal gas constant; and T is the absolute temperature.

Rearrange to solve for n:

[tex]\displaystyle n = \frac{PV}{RT}[/tex]

Because R has units of L-atm/mol-K, convert the pressure to atm:

[tex]\displaystyle 1720 \text{ kPa} \cdot \frac{1\text{ atm}}{101.3\text{ kPa}} = 17.0\text{ atm}[/tex]

And convert from Celsius to kelvins:
[tex]\displaystyle \begin{aligned}T _ k & = T_C + 273.15 \\ \\ & = (20.0) + 273.15 \\ \\ & = 293.2\text{ K} \end{aligned}[/tex]

Hence substitute and evaluate:
[tex]\displaystyle \begin{aligned} n & = \frac{PV}{RT} \\ \\ & = \frac{\left(17.0\text{ atm})(30.00\text{ L})}{\left(\dfrac{0.08206\text{ L-atm}}{\text{mol-K}}\right)(293.2\text{ K})} \\ \\ & = 21.2\text{ mol } \end{aligned}[/tex]

In conclusion, there are about 21.2 moles of acetylene in the tank.

What is a phase change?

The conversion of matter from one  state to another is called as phase change.The process is accompanied by a large amount of energy being evolved or absorbed during the process. It also depends on factors like temperature and pressure.

Each form of matter has it's own characteristic properties like specific heat, melting and boiling points . There are eight thermal processes through which matter undergoes phase change. They are as  follows:1) freezing 2) melting  3)vaporization 4)condensation 5)sublimation 6)deposition 7)ionization 8) recombination.

These eight phases exist at different temperatures  and pressures.The heat transfer process takes place in three ways which are conduction, convection and radiation.

Chemical reactions spontaneously occur when the free energy of the products is ___________ the free energy of the reactants.

Answers

Answer:

lower

Explanation:

For a spontaneous process, the standard Gibbs free energy change has to be less than zero:

∆G° < 0 → spontaneous

∆G° > 0 → non- spontaneous

∆G° = 0 → system is at equilibrium

For a negative change in standard Gibbs free energy, the Gibbs free energy of the products has to be lower than that of the reactants since Gibbs free energy change is the standard Gibbs free energy of products minus that of the reactants.

[tex]\boxed{∆G= G°(products) -G°(reactants)}[/tex]

Mathematical derivation:

G°(products) -G°(reactants) < 0

G°(products) < G° (reactants)

✩ Note that in the image attached, the Gibbs free energy change is usually denoted by a single-headed arrow, from reactants to products.

What is free energy?

Amylase was shown to work best at a ph of 7 in comparison of a ph of 2. If the stomach juices have a ph of 2, what do we know about the function of salivary amylase within the stomach?.

Answers

The salivary amylase did not perform well if the pH becomes lower because it needs neutral pH for performing its functions.

Effect of pH on the enzyme

We can say that the salivary amylase did not perform their function very well within the stomach due to unfavourable environment such as lower pH. Due to lower pH, the enzyme structure is damaged so unable to perform its function so we can conclude that the salivary amylase did not perform well if the pH becomes lower.

Milk, if 2.00 liters has a mass of 2.06 kg. Find the density in g/cm^3

Answers

Answer:

The answer is 1.03 g/cm³

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

1 kg = 1000 g

2.06 kg = 2060 g

1 L = 1000 cm³

2 L = 2000 cm³

mass = 2060 g

volume = 2000 cm³

We have

[tex]density = \frac{2060}{2000} = \frac{103}{100} \\ [/tex]

We have the final answer as

1.03 g/cm³

Hope this helps you

Answer:

The density of milk is 1.03 g/cm³.

Explanation:

Given data:

Volume of milk = 2.00 L

Mass of milk = 2.06 kg

Density of milk = ?

Solution:

We know that density is equal to the mass divided by volume.

we will convert the unit first because we require the density in g/cm³.

2.06 kg ×1000 g/ 1 kg = 2060 g

2.00 L × 1000 mL / 1L = 2000 mL

d = m/v

d = 2060 g/2000 mL

d = 1.03 g/mL

mL = cm³

d = 1.03 g/cm³

Thus, density of milk is 1.03 g/cm³.
