To convert boiling water to steam, that would involve heat of vaporization. The heat of vaporization for water at atmospheric conditions is: ΔHvap = <span>2260 J/g.
Molar mass of water = 18 g/mol
Q = m</span>ΔHvap = (1.50 mol water)(18 g/mol)(<span>2260 J/g) = 61,020 J
Time = Q/Rate = (61,020 J)(1 s/20 J) = 3051 seconds
In order to express the answer in three significant units, let's convert that to minutes.
Time = 3051 s * 1min/30 s = <em>102 min</em></span>
Answer:
See below
Explanation:
You missed the following elements, but any element with 7 valence electrons could behave like that: Cl, Br, I, F, etc
Answer:
absorbed
Explanation:
because black absorbs the light around it
<span>Answer: option B. is much less than that felt by a single proton in a small nucleus.

Explanation:
</span><span />
<span>The strong nuclear force is one of the four forces in nature: 1) strong nuclear force, 2) weak nuclear force, 3) electrostatic force, and 4) gravity.
</span><span />
<span>Strong nuclear force is the strongest of the forces and is resposible for the attraction of the protons and neutrons in the nucleus, and so it is the responsibile for the stability of the atom nuclei.
</span><span>
</span><span>
</span><span>Neverthelss, it is also a force of very low range it can act only at very small distances. That means that the larger the nucleus the weaker the force.
</span><span>
</span><span>
</span><span>That is the reason for the unstability of the large atoms.</span>
