Answer:

I'm pretty sure it is Hardness

Explanation:

It is the only thing that you personally can tell by using one of your five senses. Physical properties can only be told by the look or feel of the object. Sorry if i'm wrong

anygoal [31]

Answer:

d. supersaturated.

Explanation:

A solution naturally contains a solute and a solvent. The solute is the solid substance that dissolves in the solvent, which is usually a liquid substance. A solution has a maximum amount of solute that can dissolve in its constituent solvent.

However, when the amount of dissolved solute in a solution at a given temperature is greater than the amount that can permanently remain in the solution at that temperature, the solution is said to be SUPERSATURATED. This means that the solution contains more than the maximum amount of solute.

What is the fraction of the hydrogen atom's mass (11h) that is in the nucleus? the mass of proton is 1.007276 u, and the mass of

ololo11 [35]

Hello there!

To determine the fraction of the hydrogen atom's mass that is in the nucleus, we have to keep in mind that a Hydrogen atom has 1 proton and 1 electron. Protons are in the nucleus while electrons are in electron shells surrounding the nucleus. The mass of the nucleus will be equal to the mass of 1 proton and we can express the fraction as follows:

$Mass Fraction= \frac{mass 1 Proton}{mass H atom} = \frac{1,007276 u}{1,007825}=0,9995$

So, the fraction of the hydrogen atom's mass that is in the nucleus is 0,9995. That means that almost all the mass of this atom is at the nucleus.

Have a nice day!

A superconductor performs best at??

Charra [1.4K]

very cold temperatures

Explanation:

A superconductor performs best at very cold temperatures.

A superconductor is a perfect conductor that is able to allow the passage of electricity and heat without resistance.

In superconductors, under certain conditions, resistance ceases to exist.
Examples are aluminium, niobium e.t.c
A conductor allows heat and current to pass through but with little resistance.
