* Clopyralid is a broadleaf herbicide in the pyridine group, used mainly in turf, rangeland, and for control of noxious thistles.

Clopyralid is in the pyridine family of herbicides, which also includes picloram, triclopyr, and several less common herbicides.

Clopyralid is notorious for its ability to persist in dead plants and compost, and has accumulated to phytotoxic levels in finished compost in a few highly publicized cases.

Clopyralid is licensed for lawn use in France and under the following names:

Clopyralid is more selective for controlling plants in the Asteraceae family, but will also injure or kill legumes.

Triclopyr has also been described as effective, and Clopyralid, MCPP, and quinclorac as ineffective.

An Arrhenius acid is a substance that increases the concentration of the hydronium ion, H < sub > 3 </ sub > O < sup >+</ sup >, when dissolved in water.

Consider the following reactions of acetic acid ( CH < sub > 3 </ sub > COOH ), the organic acid that gives vinegar its characteristic taste:

Both theories easily describe the first reaction: CH < sub > 3 </ sub > COOH acts as an Arrhenius acid because it acts as a source of H < sub > 3 </ sub > O < sup >+</ sup > when dissolved in water, and it acts as a Brønsted acid by donating a proton to water.

In the second example CH < sub > 3 </ sub > COOH undergoes the same transformation, in this case donating a proton to ammonia ( NH < sub > 3 </ sub >), but cannot be described using the Arrhenius definition of an acid because the reaction does not produce hydronium.

BF < sub > 3 </ sub > is a Lewis acid because it accepts the electron pair from fluoride.

The species that gains the electron pair is the Lewis acid ; for example, the oxygen atom in H < sub > 3 </ sub > O < sup >+</ sup > gains a pair of electrons when one of the H — O bonds is broken and the electrons shared in the bond become localized on oxygen.

Although it is generally harmless to plant growth in pH-neutral soils, the concentration in acid soils of toxic Al < sup > 3 +</ sup > cations increases and disturbs root growth and function.

Carboxylic acid groups (− CO < sub > 2 </ sub > H ) can be deprotonated to become negative carboxylates (− CO < sub > 2 </ sub >< sup >−</ sup > ), and α-amino groups ( NH < sub > 2 </ sub >−) can be protonated to become positive α-ammonium groups (< sup >+</ sup > NH < sub > 3 </ sub >−).

Baltic amber yields on dry distillation succinic acid, the proportion varying from about 3 % to 8 %, and being greatest in the pale opaque or bony varieties.

* Eno-NaHCO < sub > 3 </ sub >, Citric acid, Na < sub > 2 </ sub > CO < sub > 3 </ sub >

In the presence of water, sulfur trioxide ( SO < sub > 3 </ sub >) is converted rapidly to sulfuric acid:

Further separation was carried out in the presence of a citric acid / ammonium buffer solution in a weakly acidic medium ( pH ≈ 3. 5 ), using ion exchange at elevated temperature.

Enthalpy of dissolution in hydrochloric acid at standard conditions is − 600 kJ / mol < sup >− 1 </ sup >, from which the standard enthalpy change of formation ( Δ < sub > f </ sub > H °) of aqueous Bk < sup > 3 +</ sup > ions is obtained as − 601 kJ / mol < sup >− 1 </ sup >.

One is an amino group, — NH < sub > 2 </ sub >, and one is a carboxylic acid group, — COOH ( although these exist as — NH < sub > 3 </ sub >< sup >+</ sup > and — COO < sup >−</ sup > under physiologic conditions ).

The convention for a nucleic acid sequence is to list the nucleotides as they occur from the 5 ' end to the 3 ' end of the polymer chain, where 5 ' and 3 ' refer to the numbering of carbons around the ribose ring which participate in forming the phosphate diester linkages of the chain.

Hydrochloric acid, sulfuric acid and nitric acid dissolve cadmium by forming cadmium chloride ( CdCl < sub > 2 </ sub >), cadmium sulfate ( CdSO < sub > 4 </ sub >), or cadmium nitrate ( Cd ( NO < sub > 3 </ sub >)< sub > 2 </ sub >).

In the extreme and oversimplified example suggested in Figure 3, the organization is more easily understood and more predictable in behavior.

The assumptions upon which the example shown in Figure 3 is based are: ( A ) One man can direct about six subordinates if the subordinates are chosen carefully so that they do not need too much personal coaching, indoctrinating, etc..

Furthermore, the network in Figure 3 is only the basic net through which other networks pertaining to logistics and the like are interlaced.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That the Act of July 3, 1952 ( 66 Stat. 328 ) as amended ( 42 U.S.C. 1952-1958 ), is further amended to read as follows: Section 1.

in the case of a partnership or corporation, the existence of which has been terminated and on behalf of which an award is made, payment shall be made, except as provided in paragraphs ( 3 ) and ( 4 ), to the person or persons found by the Comptroller General of the United States to be entitled thereto ; ;

Research, development test and evaluation funds, devoted to missiles in 1960 were 3 to 4 times as large as those devoted to aircraft, and actual missile procurement is expected to exceed aircraft procurement by 1963.

Tanker T., 3, 2:05.3 is now wearing hopples and has trained in 2:19 ; ;

This covered, wooden bridge is so closely identified with the first action in the early morning of June 3, 1861, and with subsequent troop movements of both armies in the Philippi area that it has become a part and parcel of the war story.

The observed intensity of the radio emission of Venus is much higher than the expected thermal intensity, although the spectrum indicated by measurements at wave lengths near 3 cm and 10 cm is like that of a black body at about 600-degrees.

Another anode holder used in the experiments is shown in figure 3.

A randomization of `` ups '' and `` downs '' is more likely than ordered `` ups '' and `` downs '' in position ( 3 ) since the hydrogen atoms are well separated and so the position of one could hardly affect the position of another, and also since ordered `` up '' and `` down '' implies a larger unit cell, for which no evidence exists.

Lung type 3 ( ( fig. 3 ) is to some degree a composite of types 1, and 2.

Arterial supply to the pleura in types 1 and 3 is provided by the bronchial artery, and in type 2, by the pulmonary artery.

In type 3, this general relationship is maintained peripherally but not centrally where the pulmonary vein follows a more independent path to the hilum as is the case throughout the lung in type 2.

For example, arrow 17 in Figure 3 portrays the proximal radial epiphysis for boy 34, whereas the same epiphysis for girl 2 is portrayed by arrow 18 in Figure 4.

The nuclei of these fibers, as is shown in Figures 3 and 4, showed remarkable proliferation and were closely approximated, forming a chainlike structure at either the center or the periphery of the fiber.

When three dice are tossed repeatedly, what is the probability that the number of aces is 0 ( or 1, or 2, or 3 )??

Considering only these Fridays, what is the probability that the coach had drivers all 3 times??

For example, the marksman gets 5 shots, but we take his score to be the number of shots before his first bull's-eye, that is, 0, 1, 2, 3, 4 ( or 5, if he gets no bull's-eye ).

During the first pass of Phase 3,, references to the actual addresses of index words and electronic switches are collected and the availability table is updated.

The one- or two-digit number of the index word or electronic switch was used in the operand of a symbolic machine instruction to specify indexing or as a parameter which is always an index word or electronic switch, e.g., 3.
