Answer:
<h2>The answer is option D</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

We have the final answer as
<h3>1.20 moles</h3>
Hope this helps you
Answer:
Approximately 53.3 %.
Explanation:
Molar mass of C2H4O2
= 2 * 12.011 + 4 * 1.008 + 2 * 15.999
= 60.052
% oxygen = (31.998* 100) / 60.052 = 53.28 %
Explanation:
The roots of trees in a forest are colonized by symbiotic fungi called mycorrhizae. These fungi are significant nitrogen fixers because they harbor nitrogen-fixing bacteria. They convert atmospheric nitrogen into nitrates and nitrites that can be absorbed by plants. The plants use these forms of nitrogen to build biomolecules such as DNA and amino acids.This nitrogen is transferred up the food chain. Eventually the nitrogen is again recycled by denitrifiers when the organisms die.
Removing trees will disrupt the symbiotic relationship with mycorrhizae, stime the nitrogen cycle in the forest.
