The greater concentration of H+ in the intermembrane space of the mitochondria more will be the more ATP production by ATP synthetase.
The high external H+ ions concentration influences concentration within intermembrane space, which increases the amount of ATP produced by ATP synthase. The functioning of ATP synthase solely depend on the gradient of H+ ion concenteration. This gradient must have a high concentration in the intermembrane space and a low concentration in the matrix. H+ cannot flow through the outer membrane of the mitochondria but can do so through the inner membrane. By putting mitochondria in a low pH buffer, an H+ gradient is created, which ATP synthase can use to synthesize ATP.
Hence, movement of H + across ATP synthase generates ATP.

Answer:
Explanation: Q1 = mc(ice) ΔT (ice warms)
Q2 = ms (ice melts)
Q3 = mc((water) ΔT (water warms)
Q4 = mr (water boils)
Q5 = mc(vapour)ΔT
in an electroplating apparatus, where does the oxidation reaction occur?
a. on the surface of the battery
b. on the surface of the cathode
c. in the solution
d. on the surface of the anode
Answer:
I believe it’s on the surface of the anode!
Explanation:
Electroplating apparatuses are the devices used in the electroplating of metals. The oxidation reaction occurs on the anode of the plate. Thus, option d is correct.
What is oxidation?Oxidation is the process of the redox reaction in which the atoms or the ions lose their electron to the positive anode. The negative of the ionic species gets attracted to the positive of the anode.
The negative ions act as charges deposited on the positively charged anode and conduct electric current. The oxidation of the species will always occur at the anode of the electrochemical cell.
Therefore, option d. oxidation occurs at the surface of the anode.

what happens when a species is moved from its natural environment?
Answer:
What may happen is everything where they used to live may change. Like The food cycle or the ecosystem. Here's a example. We took wolves from their natural environment and there was a big impact on what they did. Elks is what they ate all the time and kept their population low enough to where the environment can thrive but when they took the wolves the elks started to eat the berries in which Grizzly Bears need to feast on for their hibernation and they ate shrubs and other plant like stuff to which stuff couldn't grow anymore. The Elk population when from 5000 to 30000 from when they took the wolves that day. Another thing is how beavers build dams to keep water from going to certain places which help humans out too, but all the time the Elks would drink water and leave waste inside the water to where fish and other species inside the water started dying out. So beavers couldn't build. So this is my example of what may happen if a species is moved from their natural ground cause they could also ruin a food chain somewhere else.

Examine the structure of glucose and galactose which oh group determines that they both are the d isomers
Answer:
See Explanation
Explanation:
Stereoisomers are isomers that have the same atom to atom connectivity but differ in the arrangement of atoms or groups in space.
Glucose and galactose are stereoisomers that have more than one stereogenic center but differ in the configuration of atoms and groups about one of the stereogenic centers. This kind of stereoisomers are also called epimers.
Glucose and galactose differ in the orientation of -H and -OH at carbon-4.

Which statement describes sunspots? A.Sunspots have a bright white appearance. B.Sunspots occur in the radiative zone of the sun. C.Sunspots occur in areas of extremely low magnetic fields. D.Sunspots have lower temperatures than their surroundings.
Answer:
The statements that describe sunspots is;
D. Sunspots have lower temperatures than their surroundings
Explanation:
Sunspots is a phenomenon that involves temporary appearance of dark areas on the Sun's surface, which are regions of concentrated magnetic field flux which inhibit heat transfer by convection and are therefore cooler than other parts of the Sun. Due to the presence of magnetic field magnetic
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Opposite magnetic polarity sunspots usually appear as a pair.
Therefore, the statement that best describe sunspots is that a sunspot is a region of reduced temperature compared to surrounding areas on the Sun's surface.

What volume, in liters, of 0.500 M HNO3 is necessary to react with 25.0 mL of 0.0500 M Ca(OH)2 solution to the endpoint? HNO3 + Ca(OH)2. --> Ca(NO3)2 + H2O
Answer:
0.00500L are necessaries
Explanation:
Based on the balanced chemical reaction:
2HNO3 + Ca(OH)2. --> Ca(NO3)2 + 2H2O
2 moles of nitric acid react with 1 mole of calcium hydroxide
To solve this question we must find the moles of Ca(OH)2. Then, convert this moles to moles of HNO3 using the chemical reaction and to liters:
Moles Ca(OH)2:
0.025L * (0.0500mol / L) = 0.00125 moles Ca(OH)2
Moles HNO3:
0.00125 moles Ca(OH)2 * (2 moles HNO3 / 1mol Ca(OH)2) = 0.0025 moles HNO3
Liters HNO3:
0.0025 moles HNO3 * (1L / 0.500moles) = 0.00500L are necessaries

How to determine the relative rates of reactant disappearance and product appearance using reaction stoichiometry
Answer:
For example, the relative rate of a reaction at 20 seconds will be 1/20 or 0.05 s -1, while the average rate of reaction over the first 20 seconds will be the change in mass over that period, divided by the change in time.
