Answer:

Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

How many moles of ethylene (C2H4) can react with 12.9 liters of oxygen gas at 1.2 atmospheres and 297 Kelvin? C2H4(g) + 3O2(g) y
7nadin3 [17]
1) Convert 12.9 liters of Oxygen to mol at the given conditions:

PV = nRT ⇒ n = PV/RT

n = [1.2atm*12.9 l] / [0.082 atm l /K mol * 297K]

n = 0.636 mol of O2

2) use the stoichiometry derived from the balanced chemical equation

 1mol C2H4 / 3  mol O2 =  x mol C2H4 / 0.636 mol O2

x = 0.636 / 3 mol O2 = 0.212 mol O2.

Answer: 0.212 mol O2

Name the element described in each of the following:
musickatia [10]

Period  4  transition  element  that  forms  2+  ion  with  a  half‐filled  d  sub level  is
Manganese  (Mn)

What is the half-filled d sub-level?

Transition metals are an interesting and challenging group of elements.  They have perplexing patterns of electron distribution that don’t always follow the electron-filling rules.  Predicting how they will form ions is also not always obvious.

Transition metals belong to the d block, meaning that the d sublevel of electrons is in the process of being filled with up to ten electrons.  Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration.  In addition,  the majority of transition metals are capable of adopting ions with different charges.  Iron, which forms either the Fe2+ or Fe3+ ions, loses electrons as shown below.

Some transition metals that have relatively few d electrons may attain a noble-gas electron configuration.  Scandium is an example. Others may attain configurations with a full d sublevel, such as zinc and copper.

The molar mass of aniline is 93 g/mol. what is its molecular formula
Mashutka [201]

Answer:

Molecular formula of aniline is C6H5NH2.

Explanation:

As we know, molecular mass can be calculated as

Molar mass =  C6H5NH2

Molar mass = (6*12)+(1*7)+(28)

Molar mass  = 93 g/mol
