Answer:

in monoculture farming , we produce a single species of a livestock or plant in large quantity.

Even though it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)

which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization

Answer:

People could choose to practice organic farming, heirloom plants, or use GMOs.

Governments could pass laws to limit the use of monoculture farming.

Governments could pass laws requiring people to use alternate farming methods.

If the two atoms participating in a bond have an electron negativity difference of 1.9 , what type of of bond would they be part
brilliants [131]

Answer:

Polar covalent bond.

Explanation:

When the bond is formed between the atoms by sharing the electrons the bond thus have covalent character.   The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.  When the electronegativity difference is less than 0.4 the bond is non polar covalent.

When bonded atoms have greater electronegativity difference i.e 2 or greater than two the bond is ionic because electron is transfer from low electronegative atom to highest electronegative atom.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.

In case of H₂, Cl₂, Br₂ the bond has very high covalent character because of zero electronegativity difference.

How many moles are in 458 grams of na2so4
shtirl [24]

# moles = mass (g) / Mr (relative atomic mass)

# moles = 458 / ((23*2)+32+(16*4)

# moles= 458 /  142 = 3.2253521126760...

= 3.23 moles

A sample of gas has a density of 0.53 g/L at 225 K and under a pressure of 108.8 kPa. Find the density of the gas at 345 K under
sukhopar [10]

Answer:

\rho _2=0.22g/L

Explanation:

Hello!

In this case, since we are considering an gas, which can be considered as idea, we can write the ideal gas equation in order to write it in terms of density rather than moles and volume:

PV=nRT\\\\PV=\frac{m}{MM} RT\\\\P*MM=\frac{m}{V} RT\\\\P*MM=\rho RT

Whereas MM is the molar mass of the gas. Now, since we can identify the initial and final states, we can cancel out R and MM since they remain the same:

\frac{P_1*MM}{P_2*MM} =\frac{\rho _1RT_1}{\rho _2RT_2} \\\\\frac{P_1}{P_2} =\frac{\rho _1T_1}{\rho _2T_2}

It means we can compute the final density as shown below:

\rho _2=\frac{\rho _1T_1P_2}{P_1T_2}

Now, we plug in to obtain:

\rho _2=\frac{0.53g/L*225K*68.3kPa}{345K*108.8kPa}\\\\\rho _2=0.22g/L

Regards!
