To completely neutralise 200cm3 of 0.5mol/dm3 sodium hydroxide (NaOH), a student adds 100cm3 of 0.5mol/dm3 sulfuric acid (H2SO4)

OLga [1]

Answer:

0.1 mol

Explanation:

Step 1: Given data

Volume of the solution of sodium hydroxide (V): 200 cm³

Molar concentration of sodium hydroxide (C): 0.5 mol/dm³

Step 2: Convert "V" to dm³

We will use the conversion factor 1 dm³ = 1000 cm³.

200 cm³ × 1 dm³/1000 cm³ = 0.200 dm³

Step 3: Calculate the moles (n) of NaOH

The molarity of the NaOH solution is equal to the moles of NaOH divided by the volume of solution.

C = n/V

n = C × V

n = 0.5 mol/dm³ × 0.200 dm³ = 0.1 mol

What is a chemical bond

zvonat [6]

Hey there!

To be short and concise <u>a chemical bond</u> is the attraction between atoms that allows the creation of chemical compounds.

I hope this helps! :D

A 5 L tank of oxygen with a pressure of 23 atm is moved from room temperature of 293 K to a storage freezer at 230 K. What is th

storchak [24]

Answer: The final pressure inside the tank will be B. 18.05 atm. Gay-Lussac's law is used to predict the changes in pressure or temperature of gases. According to this law, there is a direct relationship between pressure and temperature. As the temperature of gas increases, so, too, will the pressure increase and vice versa.

Further Explanation:

We use the mathematical expression of Gay-Lussac's law to find the final pressure in the tank:

$\frac{P_{initial}}{T_{initial}} \ = \frac{P_{final}}{T_{final}}$

It is very important to note that when using this equation, all temperatures must be expressed in Kelvin. The conversion from degree Celsius to Kelvin is:

$T \ (in \ K) \ = T \ (in \ deg.\ C) \ +\ 273.15$

In the problem, we are given the following information:

P(initial) = 23 atm

T(initial) = 293 K

P(final) = ?

T(final) = 230 K

Plugging in these values in the Gay-Lussac Equation, we get:

$\frac{23\ atm}{293 \ K} \ = \ \frac{P_{final}}{230\ K} \\P_{final} \ = \frac{(23 \ atm) \ (230 \ K)}{293 \ K}\\P_{final} \ = \ 18.05 \ atm$

The tank was moved from a hotter to a cooler place. At cooler temperatures, gas particles move slower and frequency and strength of their collisions with each other and the wall of the containers decrease. This leads to a decrease in the pressure. Thus, the pressure drops from 23 atm to 18.05 atm when the tank is inside the freezer.

How does distance affect work pls quick its 15 points pls keep it short pls help!!!!

ra1l [238]

The simple equation used to calculate work is force multiplied by distance, thus as this is the case increasing the distance by a certain amount, assuming the force applied to the object is constant, the amount of work you are doing on the box for instance pushing it, is going to be greater

Since you are pushing the box with the same force covering a greater distance with the force.
