Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection
Answer:
0.96 g/cm
Explanation:
Density = Mass / volume
mass = 48 grams
Volume = l x h x w --> 5 x 2 x 5 = 50 cm
48 grams / 50 cm = 0.96 g/cm
Answer: The main difference between amylopectin and glycogen is that amylopectin is an insoluble form whereas glycogen is a soluble form. The 1,4-alpha glycosidic bonds form the linear chain of both amylopectin and glycogen while 1,6-alpha glycosidic bonds form the branches.
Explanation:
As the air molecules move through the valve they have friction as they hit the walls, and its this friction that causes it to heat up.
Decomposition reaction results in the formation of the products by splitting the reactants. Moles of mercury(ii) oxide needed are 15.63 moles.
<h3>What are moles?</h3>
Moles are the ratio of mass and the molar mass of the compound or the molecule.
Moles of oxygen are calculated as:
The balanced chemical reaction can be shown as,
From the reaction, it can be said that 1 mole of oxygen requires 2 moles of mercury oxide.
Moles of mercury oxide are calculated as:
Therefore, option C. 15.63 moles of mercury (II) oxide is needed.
