Answer:

During a change in state, the motion of the particles changes. ... Particles in a liquid can side past each other, but particles in a solid can only move enough to vibrate. Removing energy from a liquid can cause it to change to a solid. Adding energy to a solid can cause it to change to a liquid.

Hope this helps! please give me brainliest!

God bless:)

Answer:

Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).

The noble-gas notation for tin (Sn) will contain the symbol Ar Kr Xe Rn

KIM [24]

Answer: Noble-gas notation of Sn contains Kr.

Explanation: Tin ( Sn) is an element having atomic number 50.

Nearest noble gas to this element is Krypton which has an atomic number 36.

Electronic configuration or noble-gas notation for Sn is written as :

$Sn=[Kr]4d^{10}5s^25p^2$

As seen from above, Noble gas Krypton having symbol 'Kr' is coming in the electronic configuration for Tin.

What rate of reaction can be measured in the dark by determining the amount of oxygen gas consumed in a period of time?

Hatshy [7]

The rate of reaction that can be measured in the dark by determining the amount of oxygen gas consumed in a period of time is the rate of respiration.

Why?

Plants can undergo two types of reactions involving oxygen:

Photosynthesis: In this type of reaction, plants use energy from light to synthesize glucose. The chemical reaction for photosynthesis is: 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂, and this reaction produces oxygen gas in the presence of light, that means that to measure the rate of photsynthesis, you'll need to measure the amount of oxgen gas produced in a period of time.
Respiration: In this type of reaction, plants convert the energy stored in the chemical bonds of molecules such as glucose to obtain energy. The chemical reaction for respiration is: C₆H₁₂O + 6O₂ → 6H₂O + 6CO₂, since this reaction consumes oxygen gas in the dark, that means that to measure the rate of respiration, you'll need to measure the amount of oxygen gas consumed in a period of time.

Have a nice day!
