Molar mass Cu = 63.546 g/mol and AgNO₃ = 169.87
<span>1 Cu + 2 AgNO</span>₃<span> -> 1 Cu (NO</span>₃<span>)</span>₂<span> +2 Ag
</span>
63,546 -------- 2 * 169.87
? g Cu ------- 45.0
Mass ( Cu ) = 45.0 * 63,546 / 2 * 169.87
Mass ( Cu ) = 2859,57 / 339,74
Mass = 8.4169 g of Cu
hope this helps!
Answer:
Phosphorus can act as an acceptor while galium can act as a donor
Explanation:
In electronics, pentavalent atoms are used as acceptors while trivalent atoms are used donors. Hence the answers provided above.
Answer:
Enolate Alkylation
The anions from ketones, called enolates, can act as a nucleophile in SN2 type reactions. Overall an α hydrogen is replaced with an alkyl group and a new carbon-carbon bond is formed. These alkylations are affected by the same limitations as SN2 reactions previously discussed. A good leaving group, chloride, bromide, iodide or tosylate, should be used. Also, secondary and tertiary leaving groups should not be used because of poor reactivity and possible competition with elimination reactions. Lastly, it is important to use a strong base, such as LDA or sodium amide, for preparing the enolate from the ketone. Using a weaker base such as hydroxide or an alkoxide leaves the possibility of multiple alkylations occurring, and competing SN2 reactions with the base.

Which best depicts wind erosion?
B.
rolling marble
Answer:
polar
Molecules that have ends with partial negative and positive charges are known as polar molecules. It is this polar property that allows water to separate polar solute molecules and explains why water can dissolve so many substances.
