Answer:
The object is moving at a constant speed.
The solution is as follows:
The problem would only need the information of 5,600 EJ for the known sources of methane. The molar mass of methane is 16 g/mol.
802 kJ/mol(1000 J/ 1 kJ)(1 mol/16 g)(1000 g/1 kg)(x kg) = 5,600 EJ(10¹⁸ J/1 EJ)
Solving for x,
<em>x = 1.18×10¹⁴ kg of natural gas or methane</em>
Answer:
Soil conservation is important because soil is crucial for many aspects of human life as it provides food, filters air and water and helps to decompose biological waste into nutrients for new plant life. Soil can be drained away or contaminated, destroying it for use. Soil conversation involves working to reduce contamination and depletion.

hope this helps, pls mark brainliest :D
What iron gives in its abundance, it takes away in it's inability to really conduct heat and electricity well. There is enough copper around, if we are careful in its use, to make copper bottomed pots and pans. Of the three best conductors in the world (silver, gold and copper) only copper has enough around and can be inexpensively mined that we make use of it.
If you google dr. copper, you will find he is an economist as well. Copper measures the wealth of an economy by how much is used. So iron might be cheaper and more abundant, but copper will save you much more in trying to do something with it.
