Alex Ar [27]

Answer:

NiS insoluble

Mg₃(PO₄)₂ insoluble

Li₂CO₃ soluble

NH₄Cl soluble

C₁₂H₂₂O₁₁ molecules

Explanation:

<em>Predict whether the following compounds are soluble or insoluble in water.</em>

Based on the solubility rules we can say:

  • NiS: Sulfides of transition metals are highly insoluble.
  • Mg₃(PO₄)₂: All phosphates (except those with metals of Group 1) are insoluble so Mg₃(PO₄)₂ is insoluble.
  • Li₂CO₃: all salts of metals of Group 1 are soluble so Li₂CO₃ is soluble.
  • NH₄Cl: all salts of ammonium are soluble so NH₄Cl is soluble.

<em>Which of the following best describes the solute in an aqueous solution of sucrose or C₁₂H₂₂O₁₁(aq)?</em>

Sucrose is a molecular compound in which atoms are linked through covalent bonds. Thus, it does not ionize in water (is a non-electrolyte) and when it dissolves it exists as C₁₂H₂₂O₁₁ molecules.

2. How many grams of water can be warmed from 25.0°C to 37.0°C by the addition of 8,064 calories?
sertanlavr [38]

Answer:

672 g

Explanation:

We can calculate the mass of water that can be warmed from 25.0°C to 37.0°C by the addition of 8,064 calories using the following expression.

Q = c \times m \times \Delta T

where,

c: specific heat of the water

m: mass

ΔT: change in the temperature

m = \frac{Q}{c \times \Delta T  }  = \frac{8,064cal}{(1cal/g. \° C) \times (37.0 \° C - 25.0 \° C)  } = 672 g

The mass of water that can be warmed under these conditions is 672 grams.

How might scientific knowledge about monoculture farming affect societal decisions? Please be sure to answer in complete sentenc
alisha [4.7K]

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
