The sun is beating down on the concrete. it's a hot day, and you're in the house where it's conditioned. Your feet are fairly cool. When you step outside on the concrete the coldness in your feet seep into the concrete, and the heat from the concrete takes the cold away. It's like when a pot is on the stove, the pan transfers all it's cold to the hot, and the fire replaces the cold. Hope this helps!
Answer:
A pure trait is also known as a homozygous trait. Homozygous traits are either a combination of the same two dominant alleles or the same two recessive alleles. A hybrid trait is also known as a heterozygous trait, and is the pairing of a dominant and recessive allele.
Explanation:each possible combo has a term for it. When we have two capital or two lowercase letters in the GENOTYPE
This is equivalent to having a standard enthalpy change of reaction equal to 10.611 kJ
<u>Explanation</u>:
The standard enthalpy change of reaction, Δ
H
∘
, is given to you in kilojoules per mole, which means that it corresponds to the formation of one mole of carbon dioxide.
C
(s] + O
2(g]

CO
2(g]
Remember, a negative enthalpy change of reaction tells you that heat is being given off, i.e. the reaction is exothermic.
First to convert grams of carbon into moles,
use carbon's molar mass(12.011 g).
Moles of C = mass in gram / molar mass
= 0.327 g / 12.011 g
Moles of C = 0.027 moles
Now, in order to determine how much heat is released by burning of 0.027 moles of carbon to form carbon-dioxide.
= 0.027 moles C
393 kJ
Heat released = 10.611 kJ.
So, when 0.027 moles of carbon react with enough oxygen gas, the reaction will give off 10.611 kJ of heat.
This is equivalent to having a standard enthalpy change of reaction equal to 10.611 kJ
Electrons uniting with electrons of another atom is the cause in this relationship. The effect is a chemical change.
