Answer:

The correct answer is "more fluid bilayers".

Explanation:

A fatty acid is a biomolecule of lipidic nature formed by a long hydrocarbon chain of different lengths at the end of which there is a carboxyl group.

The wall of the gallbladder consists of three main layers of tissue: The mucosa covers the wall of the gallbladder. The muscular layer of smooth muscle. The serosa, which is the outer layer.

By decreasing the saturation of the fatty acid chains in phospholipids, the bile layers would reduce their thickness and become more fluid.

KHP reacts with Ba(OH)2 as follows:

2KHP + Ba(OH)2 → 2H2O + Ba²⁺ + 2K⁺ + 2P²⁻

<em>Where 2 moles of KHP reacts per mole of barium hydroxide</em>

<em />

To solve this question we must find the moles of KHP in 1.37g. With these moles and the reaction we can find the moles of Ba(OH)2 and its molarity using the volume of the solution (31.0mL = 0.0310L) as follows:

<em>Moles KHP -Molar mass: 204.22g/mol-</em>

1.37g * (1mol / 204.22g) = 0.006708 moles KHP

<em>Moles Ba(OH)2:</em>

0.006708 moles KHP * (1mol Ba(OH)2 / 2mol KHP) =

0.003354 moles Ba(OH)2

<em>Molarity:</em>

0.003354 moles Ba(OH)2 / 0.0310L =

A catalyst decreases the activation energy of a particular exothermic reaction by 56 kJ/mol, to 35 kJ/mol. Assuming that the mec

-Dominant- [34]

Answer:

Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol

Explanation:

Activation energy decreases from = 56 kj/mol to 35 kj/mol

products = 78 KJ lower in energy than reactants

Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol

attached below are the sketches of approximate energy-level for both catalyzed and uncatalyzed reactions

3- Gas in a piston has a volume of 6.6 L, a temperature of 115 °C. If the final

Maru [420]

Answer:

d- 7.58 L

Explanation:

According to Charles's law, the temperature in Kelvin is proportional to the volume of a dry gas when the pressure is constant.

Mathematically, V1/T1 = V2/ T2

V1= initial volume= 6.6 L

T1= Initial temperature= 115 °C= (115 °C +273)=388K

V2= final volume

T2= final temperature= 173 °C= ( 173 °C+ 273)= 446K

Substitute the values,

V2=( V1 × T2)/ T1

= (6.6×446)/388

= 2943.6/388

= 7.6L

Balance the following equation __N2+__O2→__N2O

fenix001 [56]

Answer:

2N₂ + O₂ → 2N₂O

Explanation:

Given equation:

N₂ + O₂ → N₂O

In balancing a chemical equation, the number of atoms on both sides of the expression must be the same.

To solve this problem, we use a simple mathematical approach;

put coefficients a,b and c

aN₂ + bO₂ → cN₂O

Conserving N;

2a = 2c

Conserving O:

2b = c

Let a = 1, c = 1 , b = $\frac{1}{2}$

multiply through by 4

a = 2, b = 1 and c = 2

Balanced equation is;

2N₂ + O₂ → 2N₂O
