Answer: 1.1 moles H2O

Explanation: It looks like the equation is already balanced for you, so the first step will be to convert 144.1 grams of HNO3 to moles. To do this find the molar mass, and use to to do your conversion.Using the numbers provided for mass, this is the equation:1(1.0) + 1(14) + 3(16) = 1 + 14 + 48 = 63 g/mol144.1 g HNO3  x   1 mol HNO3     =  2.287 mol HNO3                              63 g HNO3Now that you know how many moles of HNO3  you're starting with, use the ratio of moles in the equation to find the moles of H2O produced. The coefficient of HNO3 is 8, and H2O is 42.287 mol HNO3  x    4 mol H2O     =  1.144 mol H2O                               8 mol HNO3

Which of the following has the shortest bond lenght Options A). H2 B).N2 C).O2 D).F2
hammer [34]

Answer:

B. N2

Explanation:

The triple bonds pull the atoms closer together, and since N2 is the only molecule with the triple bond, it is the shortest bond length.

An inhibitor is added to an enzyme-catalyzed reaction at a concentration of 26.7 μM. The Vmax remains constant at 50.0 μM/s, but
fomenos

Using the Michaelis-Menten equation competitive inhibition, the Inhibition constant, Ki of the inhibitor is 53.4 μM.

<h3>What is the Ki for the inhibitor?</h3>

The Ki of an inhibitor is known as the inhibition constant.

The inhibition is a competitive inhibition as the Vmax is unchanged but Km changes.

Using the Michaelis-Menten equation for inhibition:

  • Kma = Km/(1 + [I]/Ki)

Making Ki subject of the formula:

  • Ki = [I]/{(Kma/Km) - 1}

where:

  • Kma is the apparent Km due to inhibitor
  • Km is the Km of the enzyme-catalyzed reaction
  • [I] is the concentration of the inhibitor

Solving for Ki:

where

[I] = 26.7 μM

Km = 1.0

Kma = (150% × 1 ) + 1 = 2.5

Ki = 26.7 μM/{(2.5/1) - 1)

Ki = 53.4 μM

Therefore, the Inhibition constant, Ki of the inhibitor is 53.4 μM.

Which element in Group 17 is the most active nonmetal? (1) Br (2) I (3) Cl (4) F
Maksim231197 [3]

The element of the group 17 that is most active non metal is fluorine.

The group 17 of the periodic table contains bromine(Br), iodine(I), Chlorine(Cl) and fluorine(F).

Among all the elements of the group 17. Fluorine is the smallest in size.

Because of the small size of fluorine it has the highest electronegativity in group 17.

This high electronegativity makes it a very active non metal. It provides a very high oxidizing power and low dissociation energy to the fluorine atom.

Also because of the very small size the source of attraction between the nucleus and the electrons is very high in floor in atom.

It reacts readily to form oxides and hydroxides.

So, we can conclude here that fluorine is the most active non metal of group 17.
