Answer:

C) salt

Explanation:

  • Water is a very important component of life forms and is thus an essential factor for the individual as it is an important  factor that stretches further, as it tends to absorb the heat and give out the cooling effects.  
  • The more or high density of water is characterized by the presence of sea salts and thus the amount of freshness in water is dependent on their amount of salt concentration, the layer that represents this is called as halocline and this plays a big role in the regulating the temperature of the oceanic waters.
  • Warm water bodies are known to have a high amount of salt contents and thus dryness is generally associated with the topics as compared to cool and dense water of the polar areas.

How much heat energy is required to melt 75g of ice at 0°C?
Mnenie [13.5K]

The enthalpy change for melting ice is called the entlaphy of fusion. Its value is 6.02 kj/mol. This means for every mole of ice we melt we must apply 6.02 kj of heat. We can calculate the heat needed with the following equation:

Q = N x ΔH

where:

Q  = heat

N  = moles  

ΔH  = enthalpy

In this problem we would like to calculate the heat needed to melt 35 grams of ice at 0 °C. This problem can be broken into three steps:


1. Calculate moles of water

2. multiply by the enthalpy of fusion

3. Convert kJ to J.


Step 1 : Calculate moles of water

[ 75g ] x (\frac{1 mol}{18.02g} ) =

Step 2 : Multiply by enthalpy of fusion

Q = N × ΔH  = <em> [ Step 1 Answer ]</em> ×  6.02 =

Step 3 : Convert kJ to J

[ Step 2 Answer ] x (\frac{1000j}{1kJ} ) =

Finally rounding to 2 sig figs (since 34°C has two sig figs) we get

Arrange these molecules in order of decreasing mass: C​6​H​14​ , NO​2​ , Fe​2​O​3 ​, and CaCO​
Gennadij [26K]

The decreasing order of the mass of the molecules are:

Fe2O3>C6H14>CaCO>NO2

Explanation:

Let us calculate the atomic mass of the molecules given:

C6H14                                     Atomic mass of 1 carbon atom =12.01 amu

so, 6*12+1*14                                           Atomic mass of  hydrogen=1.007

= 86 g/mol

 

Atomic mass of NO2

  = 14+ (2*15.9)

   = 14+ 31.8

     = 45.8 g/mol

Atomic mass of Fe203

( 2*55.845)+ (3*15.9)

= 159.69 g/mol

Atomic mass of CaCO

40.07+12.0107+15.99

= 68.07g/mol

The decreasing order of the mass of the molecules are:

Fe2O3>C6H14>CaCO>NO2
