Cu + Cl2 → CuCl
copper+chloride →copper(ll)chloride
<span>The answer is A. The pump and the plastic are the only ones that create pressure compared to the other choices.
When you exert a force on the pump to a closed object such as plastic, the pressure inside the pump that it gives off makes the plastic full of air. Pressure is defined to be the force per unit area or the stress within a fluid. </span>
Answer:
a.
b.
Explanation:
Hello,
a. In this case, we use the Boyle's law as en inversely proportional relationship between pressure and volume:
Thus, for the given conditions, one computes the new pressure as shown below:
b. Now, we should find the final volume for a new pressure of 10 atm:
Best regards.
The circumstances when scientists use observational research and opinion based research is when they include animals or things that cannot control for a product. Observational research is a type of research which only observes ongoing behavior and studies about it and the results only rely on the behavior observed.
Vacuoles
➡️Plants have single large vacoule as compared to the animals which have many small vacuoles.✔️
➡️The main reason behind this fact are as follows:✔️
Storage:
➡️Plants form the base of the food chain.✔️
➡️They are capable of converting inorganic matter to organic matter.✔️
➡️To store these inorganic ions they are provided with the large vacuoles.✔️
➡️Moreover, plants can not move from one place to another.✔️
➡️So, it is very
easy for a plant to be able to store extra nutrients when they are around for use later when nutrients may not be available✔️
Growth:
➡️Plant cells grow by swelling.✔️
➡️They are provided with a rigid cell wall.✔️
➡️To make this wall expand, plant cells fill their vacuoles to exert pressure from inside.✔️
