Why is soil conversation important

Chemistry
1 answer:
Vinvika [58]2 years ago
4 0

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.

What is the final temperature when 625 grams of water at 75.0 C loses 7.96 x 10 to the fourth power J ? The specific heat of wat
IgorLugansk [536]

The final temperature : 44.5 °C

<h3>Further explanation</h3>

Heat can be formulated :

Q = m . c .Δt

Q = heat, J

m = mass, g

c = specific heat, J/gC

Δt= temperature

m= 625 g

Q=7.96 x 10⁴ J

c = 4.18 j/gC

t₁=75 C

\tt Q=m.c.\Delta t\\\\7.96\times 10^4=625\times 4.18\times (75-t_2)\\\\75-t_2=30.5\\\\t_2=44.5^oC

Answer:

c.boron-11

Explanation:

The atomic mass of boron is 10.81 u.

And 10.81 u is a lot closer to 11u than it is to 10u, so there must be more of boron-11.

To convince you fully, we can also do a simple calculation to find the exact proportion of boron-11 using the following formula:

(10u)(x)+(11u)(1−x)100%=10.81u

Where u is the unit for atomic mass and x is the proportion of boron-10 out of the total boron abundance which is 100%.

Solving for x we get:

11u−ux=10.81u

0.19u=ux

x=0.19

1−x=0.81

And thus the abundance of boron-11 is roughly 81%.
