I think the correct answer from the choices listed above is option B. The following reaction does not proceed to form a product: H2O + Au---> no reaction because gold has a lower activity than hydrogen and cannot replace it. Hope this answers the question.
Mass number<span> is found by adding the </span>number<span> of protons and </span>neutrons<span>.So </span>Fluorine<span>, which has </span>9 protons<span> would be added to the </span>number<span> of neutrons, </span>8<span>. Therefore, the mass number of fluorine would be 17. Hope this helps. Have a nice day.</span>
197 grams is the mass of one atom of gold
The answer is C. <span>The density of the fluid is greater than the density of the object.</span>
The dissociation of isocyanic acid in water produces its conjugate base, C N- since it will accept a proton to form isocyanic acid.
<h3>What is a conjugate base?</h3>
A conjugate base is a substance which is formed from the loss of the hydrogen ion of an acid and which will act as a base by accepting a proton.
The dissociation of Isocyanic acid in water is given below:

The conjugate base is C N- since it will accept a proton to form isocyanic acid.
