A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
Examples of chemical changes are burning, cooking, rusting, and rotting.
Examples of physical changes are boiling, melting, freezing, and shredding.
Answer:
Explanation:
A) Reactant that can produce more of the product
Excess reactant:
In a given reaction, the reactant that is in excess supply is the excess reactant. If the amount of the excess reactant is match, more of the product will be produced.
B) Reactant that can produce a lesser amount of the product
Limiting reactant
The limiting reactant restricts the progress of the reaction. It determines the amount of product that can be formed.
C) Amount of product predicted to be produced by the given reactants
Theoretical yield
For a given amount of reactants, the theoretical yield determines the amount of products that can be produced.
Hey there! :D
This is a true statement. Gamma radiation comes from electromagnetic energy from radioactive decay. This decay has the shortest electromagnetic wave lengths and therefore has the highest photon energy. It is extremely dangerous. Radiation in general is something to be cautious of!
I hope this helps!

Answer:
334 J
Explanation:
Cuando se comprime un gas, el trabajo se realiza en el gas, por lo que el trabajo realizado es positivo.
El sistema pierde calor, por lo que el calor es negativo.
De la primera ley de la termodinámica;
E = w + q
Dónde;
w = trabajo realizado
q = calor
E = 462 J - 128 J
E = 334 J
Humans directly impacted the environment by destroying of the habitat of the other plants. Hence, option B is correct.
<h3>What is Kudzu plant?</h3>
Kudzu vine is known as a fast-growing plant since the '30s and 40's when the Soil Conservation Service paid about 8$ to every farmer who can plant an acre with this plant.
Kudzu overgrows and crowds out native plant population, for sunlight and nutrients. Therefore, it's considered 'invasive'.
It grows so quickly that it cannot be controlled and disturb other habitats of plants. Hence, option B is correct.
