Answer:
2.5.2 Atomistic Configurations of Oxygen in Silicon Crystals
Oxygen atoms are incorporated in the silicon lattice on an interstitial position (denoted by Oi), where the oxygen atom sits in an almost bond-centered position between two adjacent Si atoms [101]. Several of the local vibration modes are infrared (IR) active. The predominant IR line at 1104/cm (at room temperature) was calibrated with respect to other analytical methods, such as gas fusion and several radioactive techniques, and is used as the standard method for the quantitative determination of the oxygen content in as-grown silicon crystals (as-grown silicon usually contains only a negligible amount of precipitated oxygen).
<span>Sue added salt to water in order to make a salt solution, the original amount of water is 400 grams. In order for Sue to obtain 405 grams of salt solution using 400 grams of water, 5 grams of salt must be added.</span>
Answer:
Both answer choice 2 and answer choice 3 are correct choices.
Explanation:
Biotic factors are living components in an ecosystem. They are living organisms which affect another living component in an ecosystem.
Antibiotic factors are non living components of an ecosystem. They are chemicals which affect living organisms.
The choice 2 is correct. The seeds spread out by mice is a biotic factor interacting with an antibiotic factor
Choice 3 is correct. The seeds in the soil grow into new trees are biotic factors interacting with an antibiotic factor
Answer: The pressure of the gas in atmospheres is 1.76
Explanation:
According to ideal gas equation:

P = pressure of gas = ?
V = Volume of gas = 70.0 L
n = number of moles = 
R = gas constant =
T =temperature =


Thus the pressure of the gas in atmospheres is 1.76
