Answer:
The answer is 25.14 percent. Hope this helps.
statement about enzymes that is correct is
b. they are large molecules that increase the rate of biologically important reactions
Enzymes are proteins that catalyse, in other words increase the rate of the biological reactions.
Biological functions that are vital for the bodies to survive, have large activation energy barriers. For this reason enzymes are used that reduce the activation energy required for the reaction to initiate. this enables the reactions to proceed.
Substrates bind to the enzyme, reaction occurs and substrate converts to products, that are released from the enzyme, leaving the enzyme unchanged.
so the correct answer is B.
Hello.
balance the equation first
<span>Cu + 2AgNO3 ----> [2Ag] + Cu(NO3)2
</span>
<span>Now set up the equation </span>
<span>350gCu*(1molCu/ 63.546g Cu) * (2molAg/1molCu) * (107.8682g Ag/1molAg)
</span>
<span>Cancel out 1molCu with 1molCu, and cancel out 2molAg with 1molAg (it still remains 2mol Ag) </span>
<span>You are left with </span>
<span>350gCu*(1/63.546g Cu)*(2Ag/1)* (107.8682g Ag/1)
</span>
<span>350gCu*1*2*107.8682= 75507.74g
</span>
<span>now divide 75507.74g by 63.546g
</span>
<span>you get [1188.2374972460896g Ag]
</span>
Have a nice day
