Which sample would show stronger (intermolecular) attractive forces, the cold water or the hot water?

Answers

Answer:

Cold water

Explanation:

A simple way to solve this kind of problems is to keep in mind that:

Solids have stronger intermolecular attractive forces than liquids, and liquids have stronger forces than gases.

Cold water behaves more similarly to solids than hot water. Conversely, hot water behaves more similarly to gases than cold water. Thus, cold water has stronger intermolecular attractive forces than hot water.

You probably use the term heat many times a day. As an example, when you cook dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Why is heat the correct term to use in these examples?
A. They show that when objects are touching, they are the same temperature.
B. They show that heat flows from something warmer to something cooler.
C. They indicate that heat is created to raise the temperature of something.
D. They indicate that the kinetic energy of the particles decreases when something is heated.

Lithium and magnesium bromide react to produce lithium bromide and magnesium metal

Answers

Answer: [tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]

Explanation:

Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

A more reactive element is one which can easily lose or gain electrons as compared to the other element.

The balanced chemical equation is:

[tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]

Here Lithium being more reactive than magnesium, it can easily displace magnesium from its salt solution and form lithium bromide and magneium in elemental form.

* i think i am right and i really hope so but please dont

count it against me babe.

explanation:

Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix.

A hydrogen bond is formed when the positive end of one molecule is attracted to the negative end of another. The concept is similar to magnetic attraction where opposite poles attract. Hydrogen has one proton and one electron. This makes hydrogen an electrically positive atom because it has a deficiency of electrons.

A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even. Some chemical species, such as chains of carbon molecules, share electrons equally and are said to be nonpolar molecules

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

Part 3) What mass of H2 is produced? Answer in units of g.

Answers

Umm well this I do not know someone should know tho

Answer:

Part 1: 229.95g

Part 2: 598.5g

Part 3: 12.6g

Explanation:

Note: I learned this last week. Answer not sure.

Pls tell me if i got it right or wrong.

Mg + HCl - > MgCl2 + H2

First, balance the equation.

There is only 1 H and 1 Cl at the left side. BUT there are 2 Cl and 2 H at the right side. So you can add a 2 in front of HCl to balance it.

Mg + 2HCl - > MgCl2 + H2

Formula 1: (n= m/mr)

n = moles, m= mass, mr = molecular mass

Formula 2: (n= v/24)

v = volume

Part 1

What mass of HCl is consumed by the reaction of 3.15 mol of magnesium?

Ratio of

(look at the number in front of each)

2HCl : Mg

2 : 1

(3.15 x 2) : 3.15 moles

6.3 moles : 3.15 moles

So 2HCl has 6. 3 moles

Now use formula 1 (n = m/mr)

Calculate molecular mass of HCl

Check your periodic table

mr of HCl =(1 + 35.5) = 36.5

6.3 = m/36.5

m = 229. 95grams

Part 2

What mass of MgCl2 is produced? Answer in units of g.

Ratio of

2HCl : MgCl2

(1 +35.5) : (24+35.5x2)

36.5: 95

229.95g :?

229.95g : 598.5g

m = 598.5g

Part 3

What mass of H2 is produced? Answer in units of g.

2HCl : H2

36.5 : 2

229.95g :?

229.95g : 12.6g

m = 12.6g

What is the mass of 8.03 mole of NH3? (NH3 is 17g/mol)

Answers

Answer:

the mass of 8.03 mole of NH3 is 136.51 g

Explanation:

The computation of the mass is shown below:

As we know that

Mass = number of moles × molar mass

= 8.03 mol  × 17 g/mol

= 136.51 g

Hence, the mass of 8.03 mole of NH3 is 136.51 g

We simply multiplied the number of moles with the molar mass so that the mass could come
