Liquid. It's volume stays the same but liquid changes shape based on what it's contained in

Answer:

Explanation:

1) For every 2 moles of methane consumed, 8 moles of carbon dioxide are produced. This means that if 4 moles of methane are consumed, the reaction can occur twice, meaning 8(2)=16 moles of carbon dioxide will be produced.

2) For every 2 moles of methane consumed, 10 moles of water are produced. This means that the reaction can occur twice, and hence 10(2)=20 moles of water will be produced.

3) For every 10 moles of water produced, 13 moles of oxygen gas are consumed. This means that if we want 126 moles of water, we need the reaction to occur 12.6 times, and thus 13(12.6)=163.8 moles of oxygen gas will be consumed.

Deposition

Explanation:

Deposition: The gaseous substance turns directly into a solid without undergoing the liquid phase

The time in years taken for the sample to be reduced to 1.00 mg of Rn-222 from 36g is 0.57 years.

Total time for the decomposition of any element will be calculated by using the following equation as:
T = (t)ⁿ, where

t = half life time = 3.80 days

n = number of half lives

Let we calculate number of half lives as:
1- 36 → 18

2- 18 → 9

3- 9 → 3

4- 3 → 1.5

Almost 4 half lives are required, on putting values on the above equation, we get

T = (3.80)⁴

T = 208.51 = 208 days (approx) = 0.569 = 0.57 years. (1 yr = 365 days)

Hnece reqiuired time is 0.57 years (approx).

A 50 L baby pool has a chlorine concentration of 0.200 M. If 20 L of water evaporated on a hot summer day, 3333 M is the final concentration of the pool.

Molarity is defined as the moles of a solute per litres of a solution.

Molarity is also known as the molar concentration of a solution.

A 50 L baby pool has a chlorine concentration of 0.200 M.

So, the volume of the baby pool is 50L with a concentration of 0.200 M.

[tex]V_1[/tex]=50 L

[tex]M_1[/tex]=0.200 M

If 20 L of water evaporated on a hot summer day, the volume of the baby pool will be 30L and we have to find the concentration of the baby pool after evaporation.

[tex]V_2[/tex]=30 L

[tex]M_2[/tex]=?

Apply the formula,

[tex]M_1V_1[/tex]=[tex]M_2V_2[/tex]

50 L X 0.200 M1 = 30 L X M2

Explanation:

From the calculation as shpwn in the procedure below, the equilibrium constant of the substance is 6.9 * 10^-15.

The equilibrium constant for the solubility of aa solid in solution is called the solubility product Ksp. The Ksp shows the extent to which a solid is dissolved in solution.

Given that;

Fe(OH)2 ⇄Fe^2+ + 2(OH)^-

Ksp = s(2s)^2

We have s as 1.2 x 10^-5 M

So

Ksp = 4s^3

Ksp = 4( 1.2 x 10^-5 )^3

Explanation:

Alfred Wegener was the one who proposed the idea although he wasn't believed until after he died

The scientist who presented the theory of Continental Drift is Alfred Wegener. The correct option is D.

The continental drift idea provided an explanation for why the continents had moved from their original places. Once linked as a single entity, called a "Subcontinent."

Since continental rocks are too light to sink to the ocean floor, the common belief that mountains were to blame for their sinking was later disproved.

Alfred Lothar Wegener is a climatologist. He discovered the continental drift theory. The science of plate tectonics has now supplanted the theory of continental drift. The scientist Alfred Wegener is most closely identified with the hypothesis of continental drift. He referred to it as continental drift.

Taking into account the definition of calorimetry, the heat change that would take place as 25.7 g of liquid Ethyl alcohol are cooled from 55.2 °C to 30 °C is -1554.336 J.

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

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

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

Replacing in the expression to calculate heat exchanges:

Q= 2.40 [tex]\frac{J}{gC}[/tex]× 25.7 g× (30 °C - 55.2 °C)

Solving:

Q= -1554.336 J

Finally, the heat change that would take place as 25.7 g of liquid Ethyl alcohol are cooled from 55.2 °C to 30 °C is -1554.336 J.

Answer:

Iodine has an atomic number of 53 meaning 53 electrons and it gain 1 electron when reacting with a metal. We know the element is a non metal as is gains an electron

Ion is fluoride (F⁻), gaining 1 electron for a stable electron structure like noble gas neon (Ne).

Fluorine (F) is an element with 9 electrons in its neutral state. By gaining 1 electron, it forms the fluoride ion (F⁻) with 10 electrons. This allows the ion to achieve a stable electron configuration, following the octet rule.

Fluoride ions are highly reactive due to their electron configuration and tend to form ionic compounds. They play essential roles in various chemical and biological processes, such as dental health, where fluoride compounds are added to prevent tooth decay.

Fluoride ions' stability and reactivity make them important in various industrial and scientific applications, including the production of fluorine-containing compounds used in refrigerants, plastics, and pharmaceuticals.

Answer:

Answer:

Explanation:

Methanes boiling point would be higher than water's

Water is a liquid because particles are held close to one another by hydrogen bonds, whereas methane is a gas because the weak IMF lets particles to spread out.

Hydrocarbon methane ( CH4 ) is a main constituent of natural gas. Because methane is a greenhouse gas (GHG), its presence in the atmosphere has an impact on the planet's climate and temperature.

A range of anthropogenic (influenced by humans) and natural sources release methane into the atmosphere.

The significant difference in polarity between oxygen and hydrogen causes the water molecules to be dipolar. As a result, a strong hydrogen bond forms between the H and O of nearby water molecules, packing the water molecules so closely together that water is a liquid at ambient temperature.

Thus, water is a liquid because particles are held close to one another by hydrogen bonds, whereas methane is a gas because the weak IMF lets particles to spread out.

Salt

Explanation:

Substances can be classified into elements, compounds or mixtures in chemistry.

Elements are simple substances which cannot be broken down any further. Elements can be found in the periodic table of elements.

On the other hand, compounds and mixtures are made up of two or more elements.

When the atoms of different elements are chemically combined, they are known as compounds. The different components of a mixture can be separated by physical means, such as filtration.

For example, sodium and chlorine are elements. When chemically combined, the compound is known as sodium chloride. An example of a mixture would be sand in water.

Gold, nitrogen and carbon are elements which can be found in the periodic table as Au, N, and C respectively. Whether the element is shiny, found in the atmosphere or found in different molecules does not change the fact that they are only made of one type of atom and are thus elements.

Salt is indeed made up of two types of elements, and they are chemically combined. Table salt is known as sodium chloride (NaCl) and the 2 elements are sodium and chlorine.

Answer:

0.025 L KOH

Explanation:

Because you gave molarity and moles, I am assuming that you are looking for volume via the molarity equation. I simply plugged the given values into the molarity equation and rearranged to isolate the liters variable.

Molarity (M): 0.1 M

Moles: 0.0025 moles

Volume (L): ? L

Molarity (M) = moles / liters (L)

0.1 M KOH = (0.0025 moles KOH) / (? L KOH)

(0.1 M KOH) x (? L KOH) = 0.0025 moles KOH

? L KOH = (0.0025 moles KOH) / (0.1 M KOH)

? L KOH = 0.025 L KOH

Answer:

153 g CO₂

Explanation:

To begin, the reaction is not in its simplest form. The coefficients can be divided by two. However, this will not change the answer.

CH₄ + 2 O₂ --> CO₂ + 2 H₂O

You can find the grams of CO₂ by taking the moles of O₂, using the mole to mole ratio of O₂ to CO₂ (via the coefficients), then converting moles of CO₂ to grams. You will need the molar mass of CO₂ since you want to convert it from moles to grams. This is calculated using the values on the periodic table. The ratios should be written in a manner that allows for the cancellation of units. The answer should have 3 sig figs.

12.011 g/mol + 2(15.998 g/mol) = 44.007 g/mol CO₂
