A cloud forms around 45Á south latitude and is carried through the atmosphere on the Westerlies, as shown below. As the water mo

lecules in the cloud move through the atmosphere, which step in the water cycle is most likely to happen next?
The molecules cool and eventually condense.
The molecules break apart and eventually evaporate.
The molecules heat up and eventually rise as water vapor.
The molecules combine and eventually fall as precipitation.

Answer: fourth option: The molecules combine and eventually fall as precipitation.

In the cloud water is in the form of tiny, tiny drops. As the cloud gain more drops they will get in contact with each other, and due to the surface tension of water the drops will form bigger drops until the weight is too much and the drops fall as precipitation.

8. Based on the formula, predict whether each of the following compounds is primarily ionic or primarily covalent. a. sodium iod
Lina20 [59]

primarily ionic  include = sodium iodide( NaI) ,   calcium chloride  ( CaCl2)


primarily covalent    include  - Ammonia (NH3) , Methane ( CH4)  and  

                                                   Glucose  (C6H12O6)


Explanation

ionic  bond  is formed  when  there is complete transfer of electron between atoms. It occur  between metal  which  donate electrons and  a  non  metal which accept  electrons.

 for  example  in  formation  of CaCl2,   ca  donate  2 electron to 2  Cl atom, while  2 Cl atom accept the 2  electrons  to form ionic bond.

 Covalent bond  is formed  when two or  more  non  metal  form bond by sharing  electrons pairs.

For  example in NH3   3 pairs of electron are shared.  to form covalent bond.

The most probable mechanism of reactivity for the solvolysis of 2-chloro-norbornane is
velikii [3]

The rate determining step for the reactivity for the solvolysis of 2-chloro-norbornane depends only on the decomposition of a single molecular species which is the 2-chloro-norbornane itself. For unimolecular reactions, the mechanism pathway being followed is that of an SN1 mechanism.

Which of the following elements are already balanced in this equation? FeS₂ + Cl₂ → FeCl₃ + S₂ Cl₂
Anuta_ua [19.1K]

Fe and S are already balanced in this equation

<h3>Further explanation</h3>

Balanced indicates that the number of elements in question has the same number of atoms both on the left side (the number on the reactants side) and on the right side (the number on the product side)

Even though one of the elements is said to be balanced, the chemical equation as a whole cannot be said to be balanced, because the chemical equation has several components of the constituent elements.

To balance chemical equations, a coefficient in front of the compound is usually added either in the reactants or products

Reaction

FeS₂ + Cl₂ → FeCl₃ + S₂Cl₂

From this equation, it can be shown that: the Fe and S elements are balanced because the numbers are equal both on the left and right, while the Cl elements are not yet balanced

Fe, left=1, right=1 ⇒ balanced

S, left=2, right=1 ⇒ balanced

Cl, left=2, right=5⇒ not balanced

For balanced equations:

2FeS₂ + 5Cl₂ → 2FeCl₃ + 2S₂Cl₂

What are the molality and mole fraction of solute in a 22.3 percent by mass aqueous solution of formic acid (HCOOH)?
Vanyuwa [196]

Answer:

Mole fraction for solute = 0.1, or 10%

Molality = 6.24 mol/kg

Explanation:

22.3% by mass → In 100 g of solution, we have  22.3 g of HCOOH

Mass of solution = 100 g

Mass of solute = 22.3 g

Mass of solvent = 100 g - 22.3g = 77.7 g

Let's convert the mass to moles

22.3 g . 1mol/ 46 g = 0.485 moles

77.7 g. 1mol / 18 g = 4.32 moles

Total moles = 4.32 moles + 0.485 moles = 4.805 moles

Xm for solute = 0.485 / 4.805 = 0.100 → 10%

Molality → mol/ kg → we convert the mass of solvent to kg

77.7 g.  1 kg / 1000g = 0.0777 kg

0.485 mol / 0.0777 kg = 6.24 m
