Answer:
28.7g x 1mol//24.022g "mass of CL diatomic" = 1.19 moles of Cl2
Explanation:
You need the heat of fusion of ice to solve this problem. <span>the heat of fusion of water = 334 J/g </span><span>
the formula to solve for heat is </span>q = m·ΔH<span>f</span>
just plug the values
q= (50.0 g) (334 j/g)= 16700 joules or 16.7 Kj
The correct answer is the 3rd option A physical property is one that can be changed without altering the identity of a substance. These set of properties is not concentration dependent. They are used to describe matter. Examples are density, solubility, melting point, color and odor.
Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.
