Answer:
625=275
240=x
625x=275×240
625x=66000
x=66000/625
x=105 .6
Explanation:
If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625
The type of decay which has the greatest mass is the alpha decay. An unstable
nucleus loses the most mass if the nucleus emits an alpha particle. This type
of decay has the largest mass among the radioactive
decay. When this particle is emitted from a nucleus, it loses two protons
and two neutrons therefore large amount of mass is lost.

The molality of the solution = 17.93 m
<h3>Further explanation</h3>
Given
6.00 L water with 6.00 L of ethylene glycol(ρ=1.1132 g/cm³= 1.1132 kg/L)
Required
The molality
Solution
molality = mol of solute/ 1 kg solvent
mol of solute = mol of ethylene glycol
- mass of ethylene glycol :
= volume x density
= 6 L x 1.1132 kg/L
= 6.6792 kg
= 6679.2 g
- mol of ethylene glycol (MW=62.07 g/mol)
=mass : MW
=6679.2 : 62.07
=107.608
6 L water = 6 kg water(ρ= 1 kg/L)

This is considered a physical change because the water does not change its chemical properties - it is still water. It is simply just moving its shape such as gas form, liquid form, or solid form.
