What is the atomic number of hydrogen??

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in which order?

saveliy_v [14]

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.

A hydrocarbon would be an organic molecule in organic chemistry that is made completely of hydrogen as well as carbon. A good example of group 14 hydrides includes hydrocarbons. In general, hydrocarbons lack color and are hydrophobic. Typically, their faint smells are compared to that of gasoline and lighter fluid.

The longest unbroken carbon chain should be found and named.
Name the groups that make up this chain but instead identify them.
Beginning at the end of the chain closest to a substituent group, fraction the chain sequentially.
Give each substituent group a corresponding number but also name to indicate its placement.

Therefore, according to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.

For an enzymatically catalyzed reaction in which the measured values for KM and Vmax are, respectively, 10.0 mM and 0.172 mM min

abruzzese [7]

Answer:

17.2 minutes is the value of the turnover number.

Explanation:

Using Michaelis-Menten equation:

$V = V_{max}\times \frac{[S]}{ (Km + [S])}$

$V_{max }=k_{cat}\times E_o$

Where :

$V_{max}$ = max rate velocity

[S] = substrate concentration

$K_m$ = Michaelis-Menten constant

V = reaction rate

$k_{cat}$ = catalytic rate constant

$E_o$ = initial enzyme concentration

We have :

$K_m=10.0mM$

$E_o=10.0\mu M=10.0\times 0.001 mM$

$V_{max}=0.172 mM/min$

$V_{max}$ is the rate is obtained when all enzyme is bonded to the substrate. $k_{cat}$ is termed as the turnover number.

$k_{cat}=\frac{V_{max}}{E_o}=\frac{0.172 mM}{10.0\times 0.001 mM}$

$=17.2 minutes$

17.2 minutes is the value of the turnover number.

In an alkane the mass ratio between hydrogen and carbon is 7/36. What is the formula of alkane?

ch4aika [34]

Answer:

CnH2n+2 formula

Explanation:

Alkanes have the general formula CnH2n+2, so if an alkane had 7 carbon atoms, it would have the molecular formula C7H16.

How much ice (in grams) would have to melt to lower the temperature of 354 ml of water from 26 ?c to 6 ?c? (assume the density o

Anit [1.1K]

Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC(T2-T1)

When two objects are in contact, it should be that the heat lost is equal to what is gained by the other. From this, we can calculate things. We do as follows:

Heat gained = Heat lost
mC(T2-T1) = - mC(T2-T1)

C(liquid water) = 4.18 J/gC
C(ice) = 2.11 J/gC

(354 mL)(1.0 g/mL)(4.18 J/gC)(26 C - 6 C) = m(2.11 J/gC)(6 - 0C) 
m = 2337.63 g of ice

Woodpeckers find insects to eat by pecking holes in trees with their beaks. One day, a woodpecker finds a particular tree that o

bixtya [17]

Answer:

1. Reflex Conditioning

Explanation:

Conditioning is an aspect of learning where a stimulus works effectively in producing a response from an organism. This response becomes regular given the type of reinforcement that is administered to the organism. The reinforcement is usually a reward that is given to the organism.

This is what is observed in the woodpecker. The stimulus or reinforcement which proves effective in producing a continuous response from the woodpecker is the abundant supply of the birds favorite bugs. This reinforcement makes it possible for the woodpecker to become conditioned towards returning to the tree.
