In terms of energy what kind of system is a sealed glass terrarium on a windsill?

2 answers:

6 0

If the sealed glass is permeable to sunlight or to transfer of heat will be an open system, but if the sealed glass is a thermic glass and doesn't allow exchange of heat and exchange of solar energy (for example a mirrored glass that reflect the sunlight) and the terrarium is not exchanging energy with the surroundings will be a closed system. It is a question that doesn't specify too many details about the system in the study. It is hard to give a final answer without making some assumptions.

zavuch27 [327]

A chemical engineer has determined by measurements that there are 7.0 moles of carbon in a sample of nickel tetracarbonyl. 7 moles of oxygen are in the sample.

<h3>What is Stoichiometry ?</h3>

Stoichiometry helps us use the balanced chemical equation to measure quantitative relationships and it is to calculate the amounts of products and reactants that are given in a reaction.

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

According to Stoichiometry

$7\ \text{mol C} \times \frac{1\ \text{mol O}}{1\ \text{mol C}}$

= 7 mol O

Thus from the above conclusion we can say that A chemical engineer has determined by measurements that there are 7.0 moles of carbon in a sample of nickel tetracarbonyl. 7 moles of oxygen are in the sample.

poizon [28]

Answer:

Ionic Compound

Not the answer:

Metallic compounds are just made of one or more than one metal.

Ex. Chloride, Sodium Chloride

Covalent compounds only form between nonmetallic elements because these elements have the same or similar electronegativity values.

Ex. Water, Hydrogen

How does heat transfer takes place between any two systems?

ikadub [295]

Explanation:

For transfer of heat between any two substances or matter can be occurred by conduction or convection process.

Conduction is a process in which two objects of different temperature are placed in contact with each other. Therefore, heat transfers from hotter object to colder object until the temperature of both objects becomes equal.

For example, a metal spoon placed in a hot cup of tea.

Convection is a process in which a fluid generally liquid or gas is heated and denser material (colder) sinks at the bottom whereas less denser material (hotter) rises at the top. This causes conventional currents in the fluid.

For example, heating rice in a pot full of water.
