How many moles of copper would be needed<br> to make 1 mole of Cu,O?

azamat

Answer:

You can view more details on each measurement unit: molecular weight of Copper(I) Oxide or grams The molecular formula for Copper(I) Oxide is Cu2O. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Copper(I) Oxide, or 143.0914 grams.

The equilibrium constant for the reaction is 1.1 x 106 M. HONO(aq) + CN-(aq) ⇋ HCN(aq) + ONO-(aq) This value indicates that

kakasveta [241]

The given question is incomplete. The complete question is given here :

The equilibrium constant for the reaction is $1.1\times 10^6$ M.

$HONO(aq)+CN^- (aq)\rightleftharpoons HCN(aq)+ONO^-(aq)$

This value indicates that

A. $CN^-$ is a stronger base than $ONO^-$

B. HCN is a stronger acid than HONO

C. The conjugate base of HONO is $ONO^-$

D. The conjugate acid of CN- is HCN

Answer: A. $CN^-$ is a stronger base than $ONO^-$

Explanation:

Equilibrium constant is the ratio of product of the concentration of products to the product of concentration of reactants.

When $K_{p}>1$ ; the reaction is product favoured.

When $K_{p};$ ; the reaction is reactant favored.

$When K_{p}=1$ ; the reaction is in equilibrium.

As, $K_p>>1$ , the reaction will be product favoured and as it is a acid base reaction where $HONO$ acts as acid by donating $H^+$ ions and $CN^-$ acts as base by accepting $H^+$

Thus $HONO$ is a strong acid thus $ONO^-$ will be a weak conjugate base and $CN^-$ is a strong base which has weak $HCN$ conjugate acid.

Thus the high value of K indicates that $CN^-$ is a stronger base than $ONO^-$

Common Stand on Climate Change. We've got to reduce our dependence on foreign oil; it's a matter of homeland security. Fine. Nobody's arguing. But the solutions that get offered -- drilling in ANWR, mandating better automobile fuel efficiency, pushing ethanol -- don't really solve anything. They're politically impossible, or too expensive, or contrary to free-market forces. They're losers.
Energy-independence advocate Gal Luft looks for winners. The former lieutenant colonel in the Israel Defense Forces and counterterrorism expert fervently believes that the only way to make America safe is to make it energy independent. And so as executive director of the Institute for the Analysis of Global Security and cofounder of the Set America Free Coalition, he has set out to do just that.

Luft advises Congress and security companies. He briefs industrial and environmental groups. Yet what separates him from other energy specialists are his pragmatic solutions. He doesn't peddle pie-in-the-sky political strategies. He's a realist. He has a single goal: freeing America from the grip of foreign oil. And he wants to do it now. At right are four steps he says we can -- and should -- take today.
