This problem is describing a combustion chemical reaction between wood and oxygen which produces carbon dioxide, water, ash and char. Thus, the best conclusion about the chemical reaction is required, considering the given choices. At the end, the answer is C. "the total mass of the reaction remains the same but mass leaves the wood as smoke", according to:

<h3>Chemical reactions: </h3><h3 />

In chemistry, chemical reactions are the way we understand chemical changes, in which the composition of matter changes. However, we must keep in mind that the law of conservation of mass always takes place as matter cannot be neither created nor destroyed.

In such a way, no matter how much wood is burnt, the total mass of the reaction always remain the same, the thing is, the ash and char won't have the same mass of the wood because carbon dioxide and probably water vapors are given off towards the air.

Thereby, the answer must be C. "the total mass of the reaction remains the same but mass leaves the wood as smoke".

If a mixture looks smooth and the same throughout it is probably what

gulaghasi [49]

Answer:
<span>If a mixture looks smooth and the same throughout it is probably <u>Homogeneous</u>.

Explanation:
Mixture is the combination of different compounds which are unreactive to each other.

Mixture are classified as ...

Solutions; in which the mixed compounds are thoroughly mixed and cannot be distinguished from each other and are said to be homogeneous. In solutions the size of solute is very small (i.e. Less than 1 nm).

Colloids; in which the solute is homogeneous visually but heterogeneous microscopically. The size of particles in this case is between 1 nm to 1 </span>μm.

Suspensions; in which the mixture is heterogeneous, the particle size is greater than 1 μm and settles down (precipitation) under the influence of gravity.

An experimenter performs a RICS experiment using a mixture (mixture 1:1 of monomers and tetramers, with a total concentration of

ICE Princess25 [194]

Answer:

Raster Image Correlation Spectroscopy (RICS) is a novel new technique for measuring molecular dynamics and confocal fluorescence imaging concentrations. RICS technique extracts information on molecular dynamics and concentrations of live cell images taken in commercial confocal systems

Explanation:

RICS analysis must be performed on images acquired through raster scanning. Laser scanning microscopes generate images by measuring the fluorescence intensity in one area of a pixel at a time (a 'pixel' in this context does not have the same definition as a pixel in computer graphics, but refers to a measurement of localized intensity). The value of a pixel is obtained by illuminating a region of the sample with the focal volume of a laser beam and measuring the intensity of the fluorescence emitted. The laser beam moves to a new location and a new pixel is recorded. Each pixel can be considered to correspond to a region of the sample, with its width (called pixel size) defined by the distance the beam moves between measurements. This means that the size of a pixel is separate and independent from the size of the focal volume of the laser beam.

Covalent bonds usually occur between atoms that have

marta [7]

Answer: A: high ionization energies; high electron affinitlies.

Explanation: Covalent bonds are basically about sharing of electrons between two atoms to achieve that stable structure. They are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or fairly similar ionization energies and electron affinities). Covalent bonding usually occurs between two non-metals.

For effective and proper bonding, the two atoms involved in the covalent bonding exercise should be small and hungry for electrons. This is to enable the nuclei of both atoms to effectively attract and hold the shared electron(s) in place; hence, the need for high ionization energies & high electron affinities for a more effective covalent bonding.

In humans, infections by fungi and protists are usually more difficult to treat than bacteria infections. Suggest an explanation

Basile [38]

<span>Fungal diseases are difficult to treat mainly because they are eukaryotic organisms just like us humans, and therefore have less differences for drugs to target without harming the human body as well. Most antibiotics target e.g. the peptidoglycan layer in the bacterial (a prokaryote) cell wall, which is a safe target since eukaryotic cells do not have equivalent structures. Similarly many differences in metabolic pathways between humans and prokaryotes is often targeted by antibiotics, but metabolism of fungi and humans is much more uniform, and hence it is difficult to exclusively target the fungi only.
