Answer:
The correct answer is m= mol solute kg soivent
Explanation:
Molality is a measure of concentration, which indicates the moles of solute (in this case sodium hydroxide) in 1kg of solvent .
In this case:
0,800 kg water-----0,400 mol NaOH
1 ,000 kg water ---x=(1 ,000 kg water x 0,400 mol NaOH)/0,800 kg water
x=0,5 mol NaOH---> <em>The solution is 0,5 molal (0,5 m)</em>
Answer:
it would not melt at a specific point
Explanation:
becuase it is not pure
I believe it’s physical property because there is no chemical reaction to an unlit match♀️

How can you maximize the use of useful materials that you have identified? empty bottles, fruits peeling,old news paper
The way to maximize the use of materials identified is by identifying the 3 R's of waste management which are Reduce, Recycle and reuse .
Explanation:
For example, when we check through the materialsempty bottles, fruits peeling,old news paper them can be Reduce, Recycle and reuse.
The plastic bottles can be recycled i.e converting the waste plastic materials into another useful materials like fabric, shoes, mats.
Fruits peeling can be reuse as composts for plants. These can be allow to be decompose which serve as plant compost to release nutrients for plants growth.

Answer:
I would choose to live on mars
Explanation:
I would choose to live on mars because not only is it the most habitable planet in our solar system other than Earth, there is enough gravity on Mars to be believed that our bodies can adapt. It is also not too hot or cold for us. There is soil that water can be extracted from, and we can also use solar panels to collect energy. Although we would have to use advanced technology when going there, but I think these are a few reasons why I would prefer living on Mars over the Moon.
