Answer:
A molecule of water has two hydrogen atoms. Both of these atoms can form a hydrogen bond with oxygen atoms of different water molecules. Every water molecule can be hydrogen bonded with up to three other water molecules
Answer:
0.158L
Explanation:
From the question, we obtained the following information:
C1 = 6.84 M
V1 =?
C2 = 1.84 M
V2 = 588 mL = 588/1000 = 0.588L
Using the dilution formula C1V1 = C2V2. The original volume can calculated for as follows:
C1V1 = C2V2
6.84 x V1 = 1.84 x 0.588
Divide both side by 6.84
V1 =(1.84 x 0.588) / 6.84
V1 = 0.158L
Answer:
This study is an overview of previous studies on lime (quick and hydrated) -treated soil. Lime is the oldest traditional stabilizer used for soil stabilization. The mechanism of soil-lime treatment involves cation exchange, which leads to the flocculation and agglomeration of soil particles. The high pH environment then causes a pozzolanic reaction between the free Ca+2 cations and the dissolved silica and alumina. Lime-treated soil effectively increases the strength, durability and workability of the soil. Such treatment also improves soil compressibility. A fluctuation behavior was observed on the influence of lime on soil permeability. However, the factors affecting the permeability of the soil-lime mixture should be extensively studied. Nonetheless, lime treatment has a number of inherent disadvantages, such as carbonation, sulfate attack and environment impact. Magnesium oxide/hydroxide are thus proposed as a suitable alternative stabilizer to overcome at least some of the disadvantages of using lime in soil stabilization.

Actually I have a pdf on it to explain more if you want but how to get it to you is the issue. well I'm guessing the one I've put out should be very much okay, I hope so .

Answer:
The evidence that is most likely to support the idea that dinosaurs and their ancestors could have coexisted for millions of years is bones of three different species were found in the same rock layer (option D).
Explanation:
Fossils have been the strongest evidence of the existence of extinct species in the remote past. The discovery of some species and their possible ancestors in the same layer of rocks confirms the possibility of the coexistence of evolutionary forms of the same species, for a great period of time.
Once the fossils have been found, paleontologists use molecular genetic techniques to identify the fossils and their relationship with others found in the same place.
The approach suggests that it is not necessary for a species to become extinct in order for its evolutionary descendant to appear, considering coexistence for thousands or even millions of years.
The other options do not provide solid evidence to support this approach.
<em>A. Fewer fossils were found of amphibians than of dinosaurs, which does not specify an evolutionary relationship.</em>
<em>B. More fossils found were of larger organisms than of dinosaurs, which is not true, because species descended from dinosaurs tend to be smaller.</em>
<em>C. Herbivore bones were found in each rock layer, not related to the approach.</em>
