How to find chemical formula for copper ii nitride?

1 answer:

5 0

We know that Copper ll 's symbol is $Cu^{+2}$ and Nitride's is $N^{-2}$

Because both have opposite charges of +2 and -2, they both cancel out when written. When writing a chemical formula, the cation (positive ion/element) is written before the anion (negative ion). The formula name already had the correct order. Therefore, your chemical formula is just CuN

Hope this helps!

Answer:

D. The side chains of D-Arg and D-Lys are not positioned to bind correctly at the active site

Explanation:

Stereospecificity is the ability to distinguish between stereoisomers of of a particular compound. L- and D- structures of compounds in living organisms are usually present in only one form due to stereospecificity. For example, naturally occuring amino acids in proteins are usually present as L-isomers.

Since enzyme are proteins, their active sites are composed of L-amino acid and they show stereospecificity in the reactions they catalyze. In their binding sites, only substrates complementary in structure can bind in order for catalysis to proceed. Therefore, only amino acids in the L- configuration are complementary to the active site of enzymes.

In the case of serine proteases, The side chains of -Arg and D-Lys will not be positioned properly for binding at the binding site of serine proteases, therefore, no catalysis will occur. On the other hand, L-Arg and L-Lys can bind to the catalytic site of serine proteases since they are complementary fits to the active site of the enzymes.

Which of these alkyl halides cannot be used to prepare amines using gabriel synthesis?

wariber [46]

For Gabriel synthesis halides should be primary.
a.1-bromopentane -primary
b.1-bromo-3-methylbutane -pimary
c.2-bromo-3-methylpentane -secondary - cannot be used
d.1-bromo-2,3-dimethylbutane -primary
e.2-bromo-2,3-dimethylbutane- tertiary -cannot be used
I think it should be like this

Write the expression for the equilibrium constant Kp for the following reaction.Enclose pressures in parentheses and do NOT writ

maxonik [38]

Answer: The expression for $K_p$ is written below.

Explanation:

Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of the products and the reactants each raised to the power their stoichiometric ratios. It is expressed as $K_p$

For a general chemical reaction:

$aA+bB\rightleftharpoons cC+dD$
