List 3 common house hold items and 2 physical properties for each

physical properties for a bar of soap: hardness and color

physical properties for a book: texture and size

physical properties for tooth past: cohesiveness and taste

The correct answer is:

1. Metal pot: Hardness, fusibility

2. Glass cup: Transparent, resistant

3. Sheet of paper: White, porous

Explanation:

A physical property is one that is based primarily on the structure of the object, substance or matter, which is visible and measurable.

We can define the physical properties of an object through observation and measurement. For example, the physical properties of a wooden cube would be: dense, solid, square, wooden, organic, non-malleable, etc.

The partial pressure of hydrogen is 705.9 mmHg

Explanation:

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
