Answer:

The correct answer will be option-The bond holding the last phosphate group breaks.

Explanation:

Adenosine triphosphate or ATP is the energy molecule of the organism as it provides energy to the cell during the metabolic reaction.

The energy is stored in the phosphodiester bonds between the three phosphate molecules in the ATP molecule. The energy is released when the ATP molecule breaks down to ADP and AMP and the phosphate group is released from the molecule.

This release in the energy is used during the metabolic reactions and thus The bond holding the last phosphate group breaks is the correct answer.

The following thermochemical equation is for the reaction of nitrogen(g) with oxygen(g) to form nitrogen dioxide(g). N2(g) + 2O2

Rzqust [24]

Answer: The mass of nitrogen gas reacted to produce given amount of energy is 5.99 grams.

Explanation:

The given chemical reaction follows:

$N_2(g)+2O_2(g)\rightarrow 2NO_2(g);\Delta H=66.4kJ$

We know that:

Molar mass of nitrogen gas = 28 g/mol

We are given:

Enthalpy change of the reaction = 14.2 kJ

To calculate the mass of nitrogen gas reacted, we use unitary method:

When enthalpy change of the reaction is 66.4 kJ, the mass of nitrogen gas reacted is 28 grams.

So, when enthalpy change of the reaction is 14.2 kJ, the mass of nitrogen gas reacted will be = $\frac{28}{66.4}\times 14.2=5.99g$

Hence, the mass of nitrogen gas reacted to produce given amount of energy is 5.99 grams.

A 15.0 L tank of gas is contained at a high pressure of 8.20 x 10^4 torr. The tank is opened and the gas expands into an empty c

Inga [223]

Answer:

20.5torr

Explanation:

Given parameters:

V₁ = 15L

P₁ = 8.2 x 10⁴torr

V₂ = 6 x 10⁴L

Unknown:

P₂ = ?

Solution:

To solve this problem we have to apply the claims of Boyle's law.

Boyle's law is given mathematically as;

P₁ V₁ = P₂V₂

where P₁ is the initial pressure

V₁ is the initial volume

P₂ is final pressure

V₂ is final volume

8.2 x 10⁴ x 15 = P₂ x 6 x 10⁴

P₂ = 20.5torr
