A gas has a solubility of 1.46 g L at 8.00 atm of pressure. What is the pressure of a sample of the same gas that
uranmaximum [27]

Answer:

14.8\ \text{atm}

Explanation:

C_1 = Initial concentration = 1.46 g/L

C_2 = Final concentration = 2.7 g/L

P_1 = Initial pressure = 8 atm

P_2 = Final pressure

From Henry's law we have the relation

\dfrac{C_2}{C_1}=\dfrac{P_2}{P_1}\\\Rightarrow P_2=\dfrac{C_2}{C_1}P_1\\\Rightarrow P_2=\dfrac{2.7}{1.46}\times 8\\\Rightarrow P_2=14.8\ \text{atm}

The pressure of a sample of the same gas at the required concentration is 14.8\ \text{atm}.

suppose it takes 27 min for 1.5 g of sugar to completely react with another reagent we added to the flask. what would the reacti
labwork [276]

The rate of the reaction, given the data is 0.056 g/min

<h3>What is rate of reaction?</h3>

The rate of a reaction is simply defined as the amount converted per unit time. Mathematically, it can be expressed as:

Rate = amount / time

With the above formula, we can obtain the reaction rate. Details below:

<h3>How to determine the reaction rate</h3>

From the question given above, the following data were obtained:

  • Amount of sugar = 1.5 g
  • Time = 27 mins
  • Reaction rate =?

The reaction rate can be obtained as follow:

Reaction rate = amount / time

Reaction rate = 1.5 / 27

Reaction rate = 0.056 g/min

Thus, the reaction rate is 0.056 g/min

Find the pH of the following solution: 6.00 mL of 3.00 M HNO3 diluted to a volume of 18.0 liters with water
kupik [55]
The first thing to do is to calculate the new concentration of the solution after dilution. We do as follows:

M1V1 = M2V2
(3.0 M).006 L  = M2 (18 L)
M2 = 0.001 M HNO3

When in solution it dissociated into ions as follows:

HNO3 = H+ + NO3-

[H+] = 0.001 M HNO3 ( 1 mol H+ / 1 mol HNO3 ) = 0.001 M H+

pH = -log[H+] = -log 0.001 = 3

Lab Report: Temperature of Water and Soil
viktelen [127]

A graph enables you to easily denote the relationship between variables as positive or negative.

<h3>What is a graph?</h3>

This question is incomplete but I will try to help you as much as I can. A graph is one of the numerous was of data representation in science. A graph has two axes; the vertical ( Y - axis) and the horizontal (X - axis).

A graph enables you to easily denote the relationship between variables as positive or negative. A graph is sometimes called a scatter plot.
