Answer:
The amount of movement of tectonic plates in the area
Explanation:
The population density vary across the countries
Japan(127m), Philippines ( 103m), Indonesia (267m).
The volcanoes in Indonesia are among the most active of the pacific Ring of Fire along the north east island
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
these are the definitions so hope it helps you:
<u><em>carbon cycle</em></u><em> - Pathways through which carbon is recycled through the biosphere.
</em>
<u><em>cellular respiration</em></u><em> - Process of breaking down glucose to obtain energy in the form of ATP.
</em>
<u><em>photosynthesis</em></u><em> - Process by which specific organisms (including all plants) use the sun's energy to make their own food from carbon dioxide and water; process that converts the energy of the sun, or solar energy, into carbohydrates, a type of chemical energy.

The mass of NaN3 needed to produce 17.2 L nitrogen at STP is calculated as follows
find the moles of N2 produced at STP
At STP 1mole of gas = 22.4 L , what about 17.2 L of nitrogen
by cross multiplication
= (1 mole x17.2 L)/ 22.4 L= 0.768 moles
2NaN3 =2Na +3 N2
by use of mole ratio between NaN3 to N2 (2:3) the moles of NaN3 = 0.768 x2/3 = 0.512 moles of NaN3
mass of NaN3 is therefore =moles of NaN3 xmolar mass of NaN3
=0.512moles x 65 g/mol =33.28 grams of NaN3
Answer:
If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
