Luba_88 [7]

Complete Question

A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 74.0 wide. The biologist estimates she will need 2600 L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Round your answer to significant digits.

Answer:

The pressure required is $P_2= 12.2 \ atm$

Explanation:

Generally the volume of a sphere is mathematically denoted as

$V_s = \frac{4}{3} * \pi r^3$

Substituting $r = \frac{d}{2} = \frac{74}{2} = 37cm$

$V_s = \frac{4}{3} * 3.42 * (37)^2$

$V_s = 2.121746 *10^5 cm^3$

Converting to Liters

$V_s = \frac{2.121746 *10^5}{1000}$

$V_s= 212.1746L$

Assume that the pressure at which the air is given to the diver is 1 atm when the air was occupying a volume of 2600L

So

From Charles law

$P_1V_1 = P_2 V_s$

Substituting $V_1 =2600 L$ , $P_1 = 1 atm$ , $V_s =212.1746L$ , and making $P_2$ the subject we have

$P_2 = \frac{P_1 * V_1}{V_s}$

$= \frac{1 * 2600}{212.1746}$

$P_2= 12.2 atm$

In glycolysis, as in all the stages of cellular respiration, the transfer of electrons from electron donors to electron acceptor

Brums [2.3K]

Answer:

Oxidized,Reduced,reductant,oxidant, NAD+,NADH

Explanation:

1 when a compound donates electrons the compound becomes oxidized.such a compound is referred to as electron donor.

2 when a compound accept electron the compound becomes reduced such a compound often referred to as electron acceptor.

3 In glycolysis once the carbon containing compound that functions as electron donor is reductant.

4 once the electron donor in glycolysis gives up its electron ,it is oxidized to a compound called oxidant.

5 NAD+ is the compound that function as electron acceptor in glycolysis.

6 The reduced form of electron acceptor in glycolysis is NADH.
