Answer: chemical change because the atoms in wood and oxygen are rearranged.

Explanation: The chemical composition of wood varies from species to species, but is approximately 50% carbon, 42% oxygen, 6% hydrogen, 1% nitrogen, and 1% other elements.

When wood is being combusted in air(oxygen being the gas that rekindles the glowing splint), the chemicals are rearranged. Since about 50% of wood is carbon, C, the main chemical reaction going on here is C + O2 --> CO2. Of course, there are other chemical reactions too. But the formation of CO2 is the most common.

4.2 L of a gas has a pressure of 560mmHg at 72⁰F. What is the temperature at760mmHg if the volume is still 4.2 L? (5 pts)
IgorLugansk [536]

Answer:

The temperature at 760mmHg if the volume is still 4.2 L is 400.862 K

Explanation:

Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law can be expressed mathematically as follows:

\frac{P}{T} =k

Having an initial state 1 and a final state 2, the following is true:

\frac{P1}{T1} =\frac{P2}{T2}

In this case:

  • P1= 560 mmHg
  • T1= 72 F= 295.372 K (being 32 F= 273.15 K)
  • P2= 760 mmHg
  • T2= ?

Replacing:

\frac{560 mmHg}{295.372 K} =\frac{760 mmHg}{T2}

Solving:

T2= 760 mmHg*\frac{295.372 K}{560 mmHg}

T2= 400.862 K

What do most decomposition reactions require
NikAS [45]

Answer: Most decomposition reactions require an input of energy in the form of heat, light, or electricity. Binary compounds are compounds composed of just two elements. The simplest kind of decomposition reaction is when a binary compound decomposes into its elements.
