The first artificial use of a PGR was to stimulate the production of flowers on pineapple plants. They are now used widely in agriculture. Plant hormones are also used in turf management to reduce the need to mow, to suppress seedheads, and to suppress other types of grass.
I am in fire / ems class does anyone know anything about firefighting please answer this question thanks
What are the five fire department notifications systems chapter 37 fire detection suppression and protection systems
In an acid-base titration, the neutralization reaction between the acid and base can be measured with either a color indicator or a pH meter. In this experiment, aphenolphthalein<span> color indicator will be </span>used<span>.
</span>Phenolphthalein<span> is colorless in acidic solutions and pink in basic solutions.
Hope this helped

Answer:
Answer B) 4.2x10^17
Explanation:
To produce the reaction 3 using reaction 1 and 2 we need to invert the order of the first reaction the second in the same order, as it's shown:


____________________________

Due to the inversion of the first equation, the equilibrium constant of the new reaction is K1'=1/K1.=2.4x10^30
Finally, the new equilibrium constant K3 is the product of the previous constants:
K3=K1'*K2=4.2x10^17
Solution:
mass of the cellulose in the mixture is 0.38g
total mass of the mixture is:
3.35+0.38+8.76
=12.4g
thus the percentage of the cellulose in the mixture is:
mass of the cellulose/total mass of the mixture*100%
0.38/12.4*100%
=3%
