What container does liquid nitrogen need to be used for long-term storage?

Chemistry

Alex787 [66]2 years ago
6 0

Answer:

Impact resistant containers that can withstand the extremely low temperatures should be used. Materials such as carbon steel, plastic and rubber become brittle at these temperatures. Only store liquid nitrogen in containers with loose fitting lids (Never seal liquid nitrogen in a container).

Ans 1. Both

Ans 2. Once inside plants, carbon moves through food chains, where organisms become nutrients including herbivores, carnivores and ultimately, decomposers. Once buried in the soil, carbon can be converted into fossil fuels over long periods of time and then also reenter the atmosphere by combustion. The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law

Ans 3. Most of the chemical energy needed for life is stored in organic compounds as bonds between carbon atoms and other atoms. The law of conservation of energy states that energy can not be created or destroyed. Thus, just like matter energy is also conserved in the process.

Hope it helps

Answer:

c) Normal

Explanation:

Reflection is a phenomenon typical of light wave; it occurs when a ray of light hits the interface between two mediums, and bounces off back into the original medium, at a certain angle.

The direction of the reflected ray is determined by the law of reflection, which states that:

1) The incident ray and the reflected ray, together with the normal to the interface (the perpendicular to the interface), all lie within the same plane

2) The angle of incidence is equal to the angle of reflection:

\theta_i=\theta_r

where

\theta_i is measured as the angle between the incident ray and the normal to the interface

\theta_r is measured as the angle between the reflected ray and the normal to the interface

Answer:

The answer to your question is a balanced equation

Explanation:

Chemical formulas  are extremely useful in chemistry and these formulas follow the law of proportions but not the law of conservation of matter.

Coefficients  indicate that an equation is balanced if these numbers are in proportion but it is not the answer.

Balanced equation  is a feature of the law of conservation of matter.

Subscripts are necessary for chemical reactions but they are not a feature of the law of conservation of matter.
