Answer:
<h2>Density = 12.5 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 52.5 g
volume = 4.2 mL
Substitute the values into the above formula and solve for the density
We have
We have the final answer as
<h3>Density = 12.5 g/mL</h3>Hope this helps you
Answer:
The correct answer is option c.
Explanation:
Alkanes with higher molecular mass has higher boiling point.
Thisis because when the molar mass of the alkanes increases the the surface area increases with which van der Waals forces between the molecules of alkane also increase which increases the association of the molecules of with each other which results in increase in boiling point is observed.
The increasing order of the molar mass of the given alkanes;
So out of ethane, pentane and heptane . Heptane has highest molecular mass with higher boiling point value. Where as ethane have the lowest value of boiling point.
The reactants of photosynthesis are represented by and
.
It is a reaction through which green plants make use of inorganic products such as water and carbon dioxide in the presence of solar radiation to make sugar. Oxygen is liberated as a by-product.
The equation of the reaction is represented by:
Thus, the reactants are represented by and
respectively.
