View Available Hints

Answers

Answer:

1.45 x 10⁻² g CO₂

Explanation:

To find the mass of carbon dioxide, you need to (1) convert grams CH₄ to moles CH₄ (via molar mass), then (2) convert moles CH₄ to moles CO₂ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass). The final answer should have 3 sig figs to reflect the given value (5.30 x 10⁻³ g).

Molar Mass (CH₄): 12.011 g/mol + 4(1.008 g/mol)

Molar Mass (CH₄): 16.043 g/mol

Combustion of Methane:

1 CH₄ + 2 O₂ ---> 2 H₂O + 1 CO₂

Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)

Molar Mass (CO₂): 44.007 g/mol

5.30 x 10⁻³ g CH₄          1 mole              1 mole CO₂          44.007 g

When most fuels burn, water and carbon dioxide are the two main products. however, water and carbon dioxide are not the products of all combustion reactions. which will not form water and carbon dioxide when it burns?

Answers

Incomplete combustion does not form water and carbon dioxide when it burns.

There are two types of combustion:-1) Complete combustion:-

A fuel receives enough oxygen to complete combustion when it burns in a lot of air.

Fuels like gasoline and natural gas contain hydrocarbons. These are only hydrogen and carbon compounds. When they totally burn:

The hydrogen oxidizes to water while the carbon turns into carbon dioxide (remember that water, H2O, is an oxide of hydrogen)

for full combustion:

hydrocarbon + oxygen→Carbon dioxide + water

The following equations describe how propane, which is used in bottled gas, completely burns.

oxygen + propane→carbon dioxide + water

C3H8 + 5O2 → 3CO2 + 4H2O

2) Incomplete combustion:-

When there is insufficient air or oxygen present, incomplete combustion ensues. Carbon dioxide is still created, but it is replaced with carbon monoxide and carbon.

For incomplete combustion in general:

Hydrocarbon + Oxygen→ Carbon Monoxide + Carbon+ Water

incomplete propane combustion, which results in the production of carbon rather than carbon monoxide

oxygen + propane→carbon + water

C3H8 + 2O2 → 3C + 4H2O

How much heat is required to change 35.0 g of water from ice to liquid water?
The following information for water is given, but may or may not be useful:
C = 4.184 J/g°C
AHfus = 334 J/g
AHvap=2260J/g

Answers

Taking into account the definition of calorimetry and latent heat, 11,690 J is required to change 35 g of water from ice to liquid water.

Definition of calorimetry

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Definition of sensible heat

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

Definition of latent heat

Latent heat is defined as the energy required by a quantity of substance to change state.

When this change consists of changing from a solid to a liquid phase, it is called heat of fusion and when the change occurs from a liquid to a gaseous state, it is called heat of vaporization.

The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to

Q = m×L

where L is called the latent heat of the substance and depends on the type of phase change.

Heat to change water from ice to liquid water

In this case, you know:

Q= ?m= 35 gL= ΔHfus= 334 [tex]\frac{J}{g}[/tex] because the change consists of changing from a solid (ice) to a liquid phase (liquid water).

Replacing in the definition of latent heat:

Q = 35 g× 334 [tex]\frac{J}{g}[/tex]

Solving:

Q= 11,690 J

Finally, 11,690 J is required to change 35 g of water from ice to liquid water.

Answers

Explanation:

you need to leave some water to stop dehydration of substance

When preparing a pure and dry sample of ammonium chloride, we cannot dry the sample by evaporating it to dryness because ammonium chloride is a salt that decomposes upon heating.

When heated, ammonium chloride undergoes sublimation, which means it directly changes from a solid to a gas without passing through a liquid phase. This process would lead to the loss of the compound, and we would not be able to obtain a pure and dry sample.

Instead, other methods such as vacuum drying or desiccation are used to remove moisture from ammonium chloride without causing decomposition.

The formula for Hydroquinone is:
2. C6H6O2

Answer:

2.) C₆H₆O₂

Explanation:

(Step 1)

To find the molecular formula of hydroquinone, you need to first determine the molar mass of the empirical formula. The molar mass is a sum of the individual atomic weights of each element multiplied by their quantities (denoted by the subscripts).

Atomic Weights:

Carbon (C): 12.011 g/mol

Hydrogen (H): 1.008 g/mol

Oxygen (O): 15.998 g/mol

Molar Mass (C₃H₃O): 3(12.011 g/mol) + 3(1.008 g/mol) + 15.998 g/mol

Molar Mass (CHO): 55.055 g/mol

(Step 2)

As you can see, the molar mass of the empirical formula is not the same as the molar mass of the molecular formula. Rather, the empirical molar mass is approximately half of the molecular molar mass. Therefore, to make these masses equal, we need to double the empirical formula. This can be done by multiplying all of the subscripts by 2.

55.055 g/mol x 2 = 110.11 g/mol

110.11 g/mol = 110.108 g/mol

C₃ x 2 = C₆

H₃ x 2 = H₆

O x 2 = O₂

Therefore, the correct molecular formula of hydroquinone is C₆H₆O₂.

If the compound is 45.34% water by mass, what is the identity of element X?

Answers

The element X from the calculation is Cs.

What is the identity of element X?

We have in the question the percentage by mass of water as  45.34% thus we can write;

45.34% = 12(H20)/2(X) + Fe + 6(CN)

Hence;

45.34/100 = 12(18)/2X + 56 + 6(26)

0.45 = 216/2X + 56 + 156

0.45 = 216/2X + 212

0.45(2X + 212) = 216

0.9X + 95.4 = 216

X = 216 -  95.4/0.9

Answers

The graph of the heating of methanol has been attached.

The temperature at 170 K is approximately the melting point of methanol.

The temperature at 350 K is approximately the boiling point of methanol.

If we provide heat before 170 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in solid form.

If we provide heat at 170 K temperature then all the heat provided to the methanol will result in change in physical from of methanol from solid to liquid.

If we provide heat after 170 K temperature and before 350 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in liquid form.

If we provide heat at 340 K temperature then all the heat provided to the methanol will result in change in physical from of methanol from liquid to gas.

If we provide heat after 350 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in gas form.

Hope that helps!

#LearnwithBrainly

Answer:

D. found in nature.

Explanation:

Isotope is any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. There are 275 isotopes of the the 81 stable elements, in addition to over 800 radioactive isotopes, and every element has known isotopic forms. Isotopes of a single element possess almost identical properties.  An isotope of an element is just a version of that element with a particular number of neutrons. Some numbers are stable, some are not; the ones that aren't shoot particles out at extremely high speeds ("radiation").

Since radioisotopes generally have the same chemistry as their stable counterparts (since neutrons play almost no role in chemistry), they'll get wherever other atoms of that element would get. Iodine, for example, accumulates in your thyroid gland - so do radioactive forms of iodine, which can then cause thyroid cancer by irradiating it from the inside.

Also because they're chemically almost indistinguishable, they're almost impossible to separate out by any normal means. It's like giving someone a giant bin of golf balls, some of which are 1% heavier than the other golf balls but are otherwise exactly the same, and saying "okay, sort these". Except the golf balls are atoms and the bin is the size of a small country.
