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

Which type of decay has the greatest mass?

iVinArrow [24]

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

mass of water

6 L water = 6 kg water(ρ= 1 kg/L)

molality

$\tt =\dfrac{107.608}{6}=17.93~m$

When placed in a freezer, liquid water turns into solid ice. Why is this considered a physical change?

RSB [31]

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.
