Answer:
The correct answer is - option C.
Explanation:
Given: the melting point of HCl is
-114.8 °C, which suggests that below this temperature HCl will be solid.
and, since the boiling point of HCl is - 85.1 °C. It is also suggested that above this temperature HCl will be gas, Therefore.
Solid -114.8 - Ordered arrangement
Liquid -85.1c - Less orderly arranged
Gaseous - Least orderly arranged
Thus, at —90 °C, HCl will be present 'in the liquid state, At — 1 °C, HCl will be present in the gaseous state and at -129 °C, HCl will be present in the solid-state. So, the molecules will be organized in a more orderly manner .
Thus, the correct answer is - option C
Answer:
0.7 g/cm³
Explanation:

< The formula for density is where m = mass, v = volume, and p = density. An easy way to remember the formula is density equals love. I found this easy to remember because p = ♡ and when you think about it, if you split the heart in half through the middle like a fraction, it will make
(if you don't understand what I'm saying, try writing it out and you will be able to see what I'm talking about!)
We already know that the block is 253 g so the mass is 253 g.
To find the volume, always multiply the 3 values width, length, and height whenever you are trying to find the volume of a block.
15.24 cm x 6.64 cm x 3.56 cm = 360.25 cm³
Now plug it into the formula.³ >
