Heya it seems you’ve made a mistake in one of your plausible answers.. as for me l got 0.64M so l am thinking the option a will be in a decimal form
Produces heat, putting off air or bubbles and changes the smell or odor it changes the state that’s how you know it is a chemical reaction
Answer:
the correct answer is option ( B ) rocks cannot change their volume ,shape, and size
because a solid substance cannot change its, volume, shape and size
Hope it helps you
have a nice day
Answer:
227.78g of the precipitate are produced
Explanation:
Based on the reaction, 3 moles of CuCl2 produce 1 mole of Cu3(PO4)2 (The precipitate).
To solve this question we need to find the moles of CuCl2 added. With these moles and the reactio we can find the moles of Cu3(PO4)2 and its mass as follows:
<em>Moles CuCl2:</em>
285mL = 0.285L * (6.3mol / L) = 1.7955 moles CuCl2
<em>Moles Cu3(PO4)2:</em>
1.7955 moles CuCl2 * (1mol Cu3(PO4)2 / 3mol CuCl2) = 0.5985 moles Cu3(PO4)2
<em>Mass Cu3(PO4)2 -380.58g/mol-</em>
0.5985 moles Cu3(PO4)2 * (380.58g/mol) =
227.78g of the precipitate are produced
