Heredity refers to the passing of traits from parents to their offspring (either by asexual or sexual reproduction).
Answer:
1.15 g/mL
Explanation:
The following data were obtained from the question:
Mass (m) = 55.6 g
Volume (V) = 48.5 mL
Density (D) =?
Density is simply defined as the mass of the substance per unit volume of the substance. It is represented mathematically as:
Density (D) = mass (m) /volume (V)
D = m/V
With the above formula, we can obtain the density of the object as follow:
Mass (m) = 55.6 g
Volume (V) = 48.5 mL
Density (D) =?
D = m/V
D = 55.6/48.5
D = 1.15 g/mL
Therefore, the density of the object is 1.15 g/mL
Answer:
th mol
Explanation:
When you balance an equation, you can refer back to the coefficients when calcuating mol and molar mass from the given information about one reactant to antoher reactant ot product. you use the coeffiecients for mol-mol ratio.
for example. if you are given A +3 B -----> 6C + 5D, and you have 10 mol of A and you have to find how many mols of C with 10 mol of A. then you would ratio it as A: C = 10A: 10C= 10(1): 10(6)= 10:60. so with 10 mol A you can make 60 mol C.
Dalton's atomic theory was based on the law of conservation of mass which states that the matter can neither be created nor be destroyed but it can only transformed into one form or another. In a chemical reaction, total mass of the reactants will be equal to the total mass of the products.
Taking an example,
Mass of 
= 16g
Mass of 
= 
Total mass on reactant side = 
Total mass on reactant side = 80g
Mass of 
= 44g
Mass of 
Total mass on product side = 
Total mass on product side = 80g
It is seen from the above example that the
total mass on reactant side = total mass on product side.
Yes it is chemical because it's acid rain and other stuff that is warring it out
