Answer:

An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.

Explanation:

There are several ways of measuring the rate of photosynthesis in the lab. These include:

the rate of oxygen output

the rate of carbon dioxide uptake

the rate of carbohydrate production

These are not perfect methods as the plant will also be respiring, which will use up some oxygen and carbohydrate and increase carbon dioxide output.

Several factors can affect the rate of photosynthesis:

light intensity

carbon dioxide concentration

temperature

The amount of chlorophyll also affects the rate of photosynthesis:

plants in lighting conditions unfavourable for photosynthesis may synthesise more chlorophyll, to absorb the light required

the effects of some plant diseases affect the amount of chlorophyll, and therefore the ability of a plant to photosynthesise

Calculate the ph of a 0.25M solution of monochloroacetic acid at 25 c

Phoenix [80]

<h3>Answer: <em>pH=2.25 </em></h3>

Explanation:

monochloroacetic acid also means: chloroacetic acid

pKa of monochloroacetic acid= 1.4 x 10^-3 (I believe this should have been given in the problem or perhaps in the textbook)

Formula: pH= pKa + log ( some number in M)

pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25

pH= 2.25

True or False : An object can be in motion and not in motion at the same time depending on which frame of reference you are comp

marshall27 [118]

Answer:

True

Explanation:

Yes I agree object can be in motion and in not motion at the same time for example there are two men travelling on the bus one person is A another person is B. the person be B rest so by seeing person be the person A also sits but the person see who saw the person be B move along with person C so the the person be B is in rest for person Abut is motion for a person C.

Hunter-Best [27]

Answer:

6792.1 g

Explanation:

Dimensional analysis:

376.92 mol H2 * (2 mol h2o / 2 mol h2) * (18.02g h2o / 1 mol h2o)

Gaseous chlorine dioxide (ClO2) is used in bleaching flour and municipal water treatment in

Taking into account the ideal gas law, the pressure is 2.52 atm.

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas are related by a simple formula called the ideal gas law. This equation relates the three variables if the amount of substance, number of moles n, remains constant. The universal constant of ideal gases R has the same value for all gaseous substances. The numerical value of R will depend on the units in which the other properties are worked.

P×V = n×R×T

In this case, you know:

P=?
V= 500 L
n= 52.1 moles
R= 0.082 $\frac{atmL}{molK}$
T= 22 C= 295 K (being 0 C=273 K)

Replacing in the ideal gas law:

P×500 L = 52.1 moles ×0.082 $\frac{atmL}{molK}$ ×295 K

Solving:

P= (52.1 moles ×0.082 $\frac{atmL}{molK}$ ×295 K)÷ 500 L

Finally, the pressure is 2.52 atm.
