Adenosine triphosphate (is the answer) - It is a nucleotide, also called a nucleoside triphosphate, is a small molecule used in cells as a coenzyme. It is often called the "molecular unit of currency" of intracellular energy shift.

One problem with elimination reactions is that mixtures of products are often formed. For example, treatment of 2-bromo-2-methyl

NikAS [45]

Answer:

Structures are given below.

Explanation:

Treatment of 2-bromo-2-methylbutane with KOH in ethanol will give elimination of HBr through E2 mechanism.
H atoms adjacent to Br will be eliminated.
2-bromo-2-methylbutane has two possible adjacent H atoms that can be eliminated giving mixture of products.
Product of this elimination reaction is alkene. Here saytzeff fule is followed during elimination. So most substituted alkene will be major product.
Structure of alkenes are given below.

Equal molar quantities of Ca2 and EDTA (H4Y) are added to make a 0.010 M solution of CaY2- at pH 10. The formation constant for

abruzzese [7]

Answer:

the concentration of free Ca2⁺ in this solution is 7.559 × 10⁻⁷

Explanation:

Given the data in the question;

$Ca^{2+$ + $y^{4-$ ⇄ $CaY^{2-$

Formation constant Kf

Kf = $CaY^{2-$ / ( [ $Ca^{2+$ ][ $y^{4-$ ] ) = 5.0 × 10¹⁰

Now,

[ $y^{4-$ ] = $\alpha _4CH_4Y$ ; ∝₄ = 0.35

so the equilibrium is;

$Ca^{2+$ + $H_4Y$ ⇄ $CaY^{2-$ + 4H⁺

Given that; $CH_4Y$ = $Ca^{2+$ { 1 mol $Ca^{2+$ reacts with 1 mol $H_4Y$ }

so at equilibrium, $CH_4Y$ = $Ca^{2+$ = x

∴

$Ca^{2+$ + $y^{4-$ ⇄ $CaY^{2-$

x + x 0.010-x

since Kf is high, them x will be small so, 0.010-x is approximately 0.010

so;

Kf = $CaY^{2-$ / ( [ $Ca^{2+$ ][ $y^{4-$ ] ) = $CaY^{2-$ / ( [ $Ca^{2+$ ][ $\alpha _4CH_4Y$ ] ) = 5.0 × 10¹⁰

⇒ $CaY^{2-$ / ( [ $Ca^{2+$ ][ $\alpha _4CH_4Y$ ] ) = 5.0 × 10¹⁰

⇒ 0.010 / ( [x][ 0.35 × x] ) = 5.0 × 10¹⁰

⇒ 0.010 / 0.35x² = 5.0 × 10¹⁰

⇒ x² = 0.010 / ( 0.35 × 5.0 × 10¹⁰ )

⇒ x² = 0.010 / 1.75 × 10¹⁰

⇒ x² = 5.7142857 × 10⁻¹³

⇒ x = √(5.7142857 × 10⁻¹³)

⇒ x = 7.559 × 10⁻⁷

Therefore, the concentration of free Ca2⁺ in this solution is 7.559 × 10⁻⁷

In bullet points: explain the difference between thermal energy, heat and temperature.

sergeinik [125]

Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.
