The melting point of ice is 0 degrees Celcius, which means it exists as a liquid for any temperatures above 0 degrees. The melting point of salt is approximately 800 degrees Celcius, which is way greater than the melting point of ice. This means that for temperatures below 800 degrees, salt exists as a solid.
The temperature of the area where they were placed we can assume was somewhere between 0 and 800 degrees, greater than the melting point of ice but less than the melting point of salt. This why the ice melted but the salt did not.
I hope this helps!
The theory of blending inheritance was used to describe an actual blending of our alleles, that together would form a new allele. For example, skin color and height would be the result of the blend of the parent's alleles.
This theory doesn't explain why some traits disapear or are discrete.
On the other hand, Mendel's experiments with seed colors explains it. He demonstrated that genes are inherited in pairs and that in hybrid organisms, dominant versions of that gene, could hide the presence of a recessive version of that same gene.
Answer:
The correct answer is B. and C. according to me!
Answer:
it is released as lower energy
Answer:
True
Explanation:
Limiting reagent is the reactant that determines the progress of the reaction. It determines how much of the product is formed.
The equation for this reaction is;
NaCl (aq) + NH4HCO3 (aq) → NaHCO3 (aq) + NH4Cl (aq)
From the reaction, 1 mol of NaCl reacts with 1 mol of NH4HCO3 to produce 1 mol of NaHCO3
Converting to masses using; Mass = Number of moles * Molar mass
58.44g of NaCl reacts with 79.056g of NH4HCO3
If we were to sue the whole 1.2 g of NH4HCO3 we would require xg of NaCl
58.44 = 79.056
x = 1.2
x = 0.887g
The fact that 1.2g of NH4HCO3 requires 0.887g of NaCl (which is less than the available 0.75g) means that NaCl is the limiting reagent.
