tankabanditka [31]

Answer: Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move. They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called amoeboids.

An acetylene tank has a volume of 390.0 L. It is stored at a temperature of 23.5 °C and has a

Considering the ideal gas law, there are 279.42 moles of acetylene in the tank.

<h3>Definition of ideal gas</h3>

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

<h3>Ideal gas law</h3>

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of gases:

P×V = n×R×T

<h3>Moles of acetylene</h3>

In this case, you know:

P= 1765 kPa= 17.4192 atm (being 101.325 kPa= 1 atm)
V= 390 L
n= ?
R= 0.082 $\frac{atmL}{molK}$
T= 23.5 °C= 296.5 K (being 0 °C= 273 K)

Replacing in the ideal gas law:

17.4192 atm× 390 L = n×0.082 $\frac{atmL}{molK}$ × 296.5 K

Solving:

$n=\frac{17.4192 atmx 390 L}{0.082 \frac{atmL}{molK}x296.5 L}$

<u><em>n= 279.42 moles</em></u>

Finally, there are 279.42 moles of acetylene in the tank.

Observation or inference<br> The container is filled to the 350 ml mark with water

Luba_88 [7]

Observation is acknowledging and noting some facts from the surroundings or the environment. Usually, observation is done using the five senses of human such as the sense of sight, sense of smell, sense of touch, sense of hearing and sense of tasting. It can also be qualitative and quantitative. Qualitative observations are those who use non-numeric forms in expressing the observation however quantitative uses numeric forms in presenting the observation. Inference on the other hand is the probable explanation or interpretation based on the observation given. Therefore, the statement "The container is filled to the 350 ml mark with water " is an observation.
