Explanation:

The enthalpy of combustion of 1 mole of benzene is 3169 kJ/mol .

The first step in answering this question is to obtain the balanced thermochemical equation of the reaction. The thermochemical equation shows the amount of heat lost or gained.

The thermochemical equation for the combustion of benzene is;

2 C6H6(l) + 15 O2(g) → 12 CO2(g) + 6 H2O(g) ΔrH° = -3169 kJ/mol

We can see that 1 mole of benzene releases about 3169 kJ/mol of heat.

Answer:

option A it has equal numbers of electrons and protons

Explanation:

electrons are negatively charged and protons are positively charged, so if the numbers of each are equal, then the atom will be neutral.

Answer:

A. it has equal numbers of electrons and protons

Explanation:

The overall charge of every atoms is neutral because the number of electrons and protons is the same. Protons are positively charged while electrons are negatively charged and so they cancel out.

Answer:

The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. The max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. With 5 or 6 mentos the explosion went only 330 and 310 cm high.

Answer:

170 dm³ (2 significant figures)

Explanation:

CH₄ + 2O₂ → CO₂ + 2H₂O

We need to find how much 'volume' of O₂ is required to burn 56 g of CH₄.

Let's take the ratios of the two gases only.

CH₄ : 2O₂ (in terms of moles the ratio is 1:2)

56g : x dm³

Mr of CH₄ : Volume of oxygen at rtp

Find the Mr of CH₄.

Mr of CH₄ = 12 + (1 × 4) = 16

We know that 1 mole of any gas occupies 24 dm³ at room temperature and pressure (rtp). We have to find the volume of oxygen, there are 2 moles of oxygen, so 2 moles of gas will occupy:

2 × 24 = 48 dm³

56g : x dm³

  16 : 48 dm³

16x = 56 × 48

16x = 2688

x = [tex]\frac{2688}{16}[/tex]

x = 168 dm³

∴ the minimum volume of oxygen gas, at room temperature and pressure required to completely burn 56g of methane gas is 170 dm³

Answer:

The lack of accuracy and underestimation of absorbance readings obtained from the colorimeter can be contributed to many experimental factors. One plausible error is from the imperfection of the absorber, in that it may not completely absorb the stray light passing by the perimeters of the photoresistor.

Explanation:

In practice there are other sources of error, such as environmental effects on photometer and sample, temperature, line voltage fluctuations, vibrations, contamination, or heating of the sample by the photometer. All these factors may impair the measured result, and ways and means are known to test and eliminate them.

Explanation:

Explanation: In solids, particles are very closely packed in an orderly arrangement in a lattice and only vibrate in fixed positions. The forces of attraction between them are very strong. This allows them to overcome the forces of attraction that hold the other phases closer together

Answer:

75%

Explanation:

So, the reaction will consume 1 mole of hydrogen gas and produce

1mole H2⋅2 moles NH33moles H2=0.667 moles NH3

at 100% yield. This represents the reaction's theoretical yield.

Now, you know that the reaction produced 0.50 moles of ammonia. This represents the reaction's actual yield.

In order to find the percent yield, you need to figure out how many moles of ammonia are actually produced for every 100 moles of ammonia that could theoretically be produced.

You know that 0.667 moles will produce 0.50 moles, so you can say that

100moles NH3.in theory⋅0.50 moles NH3.actual0.667moles NH3.in theory=75 moles NH3.actual

Therefore, you can say that the reaction has a percent yield equal to

% yield = 75%

Answer:

1. Get the mass of each element by assuming a certain overall mass for the sample (100 g is a good mass to assume when working with percentages). ...

2. Convert the mass of each element to moles. ...

3. Find the ratio of the moles of each element. ..

4. Use the mole ratio to write the empirical fomula

Answer:

Multiply each result by the given mass.

Explanation:

Hi!

In order to find percent/mass composition you would

1. write the formula

2. calculate the molar mass for each equation

3. add all the masses to get the compound molar mass

4. divide each molar mass by the total mass

and then for mass composition, you would multiple eachy result by the given mass.

For example;

Calculate the number of grams of gold in 89.6 grams of gold(1) perchlorate.

Your formula would be AuClo4

Au : 196.96 x 1

Cl: 35.4 x 1

O: 16 x 4

Add the masses together to get 296.5 g/mol

Lets say we're looking for Oxygen. You would take what you got (16 x 4) and divide it by the total mass. 64/296.5

This would equal 0.215. Instead of multiplying this by 100 like you would for percent, for mass you would multiply by what is given. in this instance it is 89.6.

0.215 x 89.6 = 19

But the question is asking for gold,

197/296

= 0.664 x 89.6

= 59.5

Your answer would be 59.5 grams Au

They may be the same substance even though they have different volumes and masses.

Intensive properties are the properties are characteristic  a substance. Intensive properties are those properties of a substance that can be used to describe the substance.

We can see that the substances have similar reactivity and similar density. This means that they may be the same substance even though they have different volumes and masses.

The correct option is; "Yes, it is possible because they have similar intensive properties."
