Describe two ways that climate change can degrade soil in 3-4 sentences.

1 answer:

8 0

The two ways that climate change can degrade soil are due to carbon dioxide content in soil and its effect on the ecosystem.

Explanation:

When the concentration of carbon dioxide in the atmosphere increases the organisms such as microbes in the soil break down the organic matter and causes even more increase in the carbon dioxide content. This leads to the release of greenhouse gases which further releases a large amount of methane which is harmful.

Secondly, there should always be a balance between the soil and the climate otherwise it would affect the natural and semi-natural ecosystems. When there are changes in the distribution of water to the plants it affects the hydro-logical cycle. Thus, climate change will naturally lead to changes in the functions of soil and degradation occurs.

The fact that HBO2, a reactive compound, was produced rather than the relatively inert B2O3 was a factor in the discontinuation

Reil [10]

Answer:

1027.62 g

Explanation:

For $B_2H_6$ :-

Mass of $B_2H_6$ = 296.1 g

Molar mass of $B_2H_6$ = 27.66 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{296.1\ g}{27.66\ g/mol}$

$Moles\ of\ B_2H_6= 10.705\ mol$

From the balanced reaction:-

$B_2H_6(g) + 3 O2_{(l)}\rightarrow 2 HBO_2_{(g)}+ 2 H_2O_{(l)}$

1 mole of $B_2H_6$ react with 3 moles of oxygen

Thus,

10.705 mole of $B_2H_6$ react with 3*10.705 moles of oxygen

Moles of oxygen = 32.115 moles

Molar mass of oxygen gas = 31.998 g/mol

<u>Mass = Moles * Molar mass = 32.115 * 31.998 g = 1027.62 g</u>

A 75.0 g sample of dinitrogen monoxide is confined in a 3.q L vessel. What is the pressure( in atm) at 115 celsius

Nonamiya [84]

Data Given:
Pressure = P = ?

Volume = V = 3.0 L

Temperature = T = 115 °C + 273 = 388 K

Mass = m = 75.0 g

M.mass = M = 44 g/mol

Solution:
Let suppose the Gas is acting Ideally. Then According to Ideal Gas Equation,
P V = n R T
Solving for P,
P = n R T / V ------ (1)
Calculating Moles,
n = m / M

n = 75.0 g / 44 g.mol⁻¹

n = 1.704 mol

Putting Values in Eq. 1,

P = (1.704 mol × 0.08205 atm.L.mol⁻¹.K⁻¹ × 388 K) ÷ 3.0 L

P = 18.08 atm
