Answer:
60%
Explanation:
M(NH4NO3) = 2*14 +4*1 +3*16 = 80 g/mol
M(3O) = 3*16 = 48 g/mol
(48/80) *100 % =60% oxygen by mass.
It would cause the whole food chain to collapse.
explanation: primary consumers or herbivores, which feed of producers would directly die off. Higher level consumers would suffer as organisms from lower tropic levels start to die off
Answer: 1
Explanation: C= 1 if you round 1.04 to a single digit the answer is 1
1. Soil serves as a:
medium for plant growth,
regulator of water supplies,
recycler of raw materials,
habitat for soil organisms, and.
landscaping and engineering medium.
2. Soil organisms, which range in size from microscopic cells that digest decaying organic material to small mammals that live primarily on other soil organisms, play an important role in maintaining fertility, structure, drainage, and aeration of soil.
3. Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
Answer:
d = 3.29 g/cm³
Explanation:
Given data:
Density of material = ?
Mass of material = 56.6 g
Volume of material = 17.2 cm³
Solution:
Formula;
d = m/v
d = density
m = mass
v = volume
by putting values,
d = 56.6 g/ 17.2 cm³
d = 3.29 g/cm³
