which contains more moles of material: 80 grams of helium gas (he, having atomic weight 4.0 g/mol) or 400 grams of argon gas (ar, having atomic weight 40 g/mol)?

Answers

Answer 1

More material per mole can be found in helium.

The unit of measurement for quantity is the mole. Things react in straightforward mole ratios. However, as balances do not provide readings in moles, you must convert them into grams when comparing the amount of one material to another using moles.

To convert molecular weights to grams, follow these three procedures.

1. Determine the number of moles mentioned in the question.

2. Determine the substance's molar mass.

3. Multiply the two figures.

Avogadro's number of atoms makes up one mole. The amount of a mole can be translated to grams if you know how many there are, and vice versa.

80g/4g/mol helium = 20 Mol

400g/40g/mol of argon = 10 mol

a metal crystal is made up of metal ions held together by an ""electron sea"" of valence electrons. why does this configuration make metals good electrical conductors?

Answers

The electrical conduction is due to movement of free electron sea.

The valence electrons of metals that are close to one another do not only stay on their own atom, they move freely across the entire metal complex. Like a single water molecule floating freely in the sea, they appear to be floating through an ocean of electrons. It is known as the electron sea model for this reason.

Since each metal atom is free to move around, these atoms develop into positively charged cations. These cations are surrounded by a sea of negatively charged electrons, making them resemble a positively charged island. Metal is a good conductor of electricity because of these free-moving electrons.

A multiple dilution is a process of diluting a sample with a known concentration to create a series of dilutions that can be tested further. In this case, a sample with an initial concentration of 1650 mg/dl is to be diluted in five tubes. The dilution concentrations are 1/5 (tube 1), 1/2 (tube 2), 1/4 (tube 3), 1/5 (tube 4), and 1/10 (tube 5).

To calculate the diluted concentration in each tube, the initial concentration must be multiplied by the dilution factor. The dilution factor is the inverse of the dilution ratio. For example, for a 1/5 dilution, the dilution factor is 5.

The diluted concentration in each tube is then as follows:

Tube 1: 1650 mg/dl x 1/5 = 330 mg/dl

Tube 2: 1650 mg/dl x 1/2 = 825 mg/dl

Tube 3: 1650 mg/dl x 1/4 = 412.5 mg/dl

Tube 4: 1650 mg/dl x 1/5 = 330 mg/dl

Tube 5: 1650 mg/dl x 1/10 = 165 mg/dl

When 50.0 g of water decompose, how many grams of hydrogen are produced?

This question is driving me mad-

Answers

44.44 grams of hydrogen are produced in this equation

This can be shown as :

Let's start by balancing the equation.

We can see that, as written, we have one oxygen coming in, but two (O2) on the product side.  

H2O →  H2 + O2

Let's try making it 2 H2O and see what happens:

2H2O →  H2 + O2

That took care of the O's, but now we have two extra H's coming in.  So let's add a "2" to the H2 on the product side:

2H2O →  2H2 + O2

Now it is balanced.  4 hydrogens and 2 oxygens coming in, and 4 hydrogens and 2 oxygens going out.

Now we can calculate the amounts of both products.

We need to find the percent by mass of both hydrogen and oxygen in the water.

Since the formula for water is H2O, take the masses off of the periodic table: 2x1g for hydrogen (because there are 2 H in the formula); 1x 16g for oxygen (because there is 1 O in the formula), added together for a total of 18g.

Hydrogen’s Percentage is :

2g/18g x 50 = 5.56

Oxygen's Percentage is :

16g/18g x 50 = 44.44

why do acids react with carbonates?

Answers

Answer:

This is because the carbonate ion (CO32-) is a base, and when it reacts with an acid, it neutralizes the acid and forms a salt. The carbon dioxide that is produced is a byproduct of this reaction.

Explanation:

The reaction between an acid and a carbonate can be represented by the following general equation:

Acid + Carbonate --> Salt + Water + Carbon Dioxide

For example, the reaction between hydrochloric acid (HCl) and sodium carbonate (Na2CO3) can be written as:

HCl + Na2CO3 --> 2NaCl + H2O + CO2

In this equation, hydrochloric acid and sodium carbonate react to form sodium chloride (table salt), water, and carbon dioxide.

It's important to note that not all acids will react with carbonates. For example, sulfuric acid (H2SO4) is a strong acid, but it does not react with carbonates. This is because sulfuric acid is a strong dehydrating agent and will remove water from the reaction, preventing the formation of carbon dioxide.

Hg2+ is Lewis Acid.

According to the Lewis definition, a species that donates a lone pair of electrons acts as a Lewis base, and a species that accepts a lone pair of electrons acts as a Lewis acid.

In other words, a neutral or negatively charged species with a lone pair of electrons can act as a Lewis base, and a species with an empty orbital (an incomplete octet) which can acquire a lone pair of electrons are Lewis acid.

In case of the following reaction: hg2+(aq)+4cn−(aq)⇌hg(cn)42−(aq)

Here, the Hg2+ ion receives four pairs of electrons from the CN- ions because it possesses vacant orbitals.

So, Hg2+ is Lewis acid here.
