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.

Give the following number of protons, neutrons, and electrons in the following isotope:
valina [46]

Answer:

47, 68, 47

Explanation:

Let's consider the following isotope: ¹¹⁵Ag.

If we look in the Periodic Table, the atomic number of Ag is 47, that is, silver has 47 protons.

Since ¹¹⁵Ag is neutral it must have the same number of protons that of electrons. Then, it also has 47 electrons.

The number 115 in ¹¹⁵Ag stands for the mass number, which is the sum of protons and neutrons. Then, the number of neutrons is:

p⁺ + n⁰ = 115

n⁰ = 115 - p⁺ = 115 - 47 = 68

The number of protons, neutrons, and electrons in ¹¹⁵Ag is: 47, 68, 47.

Suppose you were calibrating a 100.0 ml volumetric flask using distilled water. the flask temperature was at 20°c, and you assum
kicyunya [14]
The density of water at 12°C is lower than the density of water at 20°C.

Now density is related to volume as per: density = mass / volume =>

mass = volume * density.

So, the greaer the density the higher the mass of the same volume of water.

Therefore, 100.0 ml of water at 12°C has a mass greater than 100.00 ml of water at 20 °C.
