The density of an object is the mass of the object compared to its volume. The equation for density is: Density = mass/volume or D = m/v. Each substance has its own characteristic density because of the size, mass, and arrangement of its atoms or molecules.

a 25.0ml dsmplr og 0.105M HCI was titrated with 31.5ml of NaOH. What is the concentration of the NaOH I got 0.0834M am I correct HCI + NaOH -----> H20 + NaCl 25.0ml HCI x 1L/1000mlx0.105 mol HCI/1L HCI X 1 mol NaOH/ I mol HCI = 0.0834M

Answer: The given reaction is a neutralization reaction.
Explanation:
When an acid chemically reacts with a base then it leads to the formation of salt and water.
For example,
Here, KOH is a the base and is an acid which on chemical reaction with each other leads to the formation of salt and water .
Thus, we can conclude that the given reaction is a neutralization reaction.
<u>Answer:</u> The partial pressure of hydrogen is 705.9 mmHg
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of hydrogen gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the collection tube, = 729.8 mmHg
Vapor pressure of water, = 23.8 mmHg
Putting values in above equation, we get:
Hence, the partial pressure of hydrogen is 705.9 mmHg
