The molecular formula of butane is C4H10. It is obtained from petroleum and is used commonly in LPG (Liquefied Petroleum Gas) cylinders (a common source of cooking gas). It has two arrangements of carbon atoms: a straight chain and a branched chain. Using this information, draw the structure of the tertiary butyl radical that will form upon removal of a hydrogen atom. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds).

Answer:oxygen and sugars

Explanation:

Answer:

Each carbon atom is tetrahedral

Explanation:

If we consider a model of ethane, we will quickly discover that all carbon atoms are bonded to four other atoms. This means that there are four regions of electron density around each carbon atom.

According to the valence shell electron pair repulsion theory, when a central atom has four regions of electron density on its outermost shell, the molecule must have a tetrahedral geometry.

Explanation:

Soil is composed of various substances in varying proportion.

An example of a heterogeneous mixture is soil as it composed of different phases while all the other 3 substances are composed of single phase.

Heterogeneous mixtures is defined as a type of mixture where in the composition is not uniform throughout the mixture.It consists as two or more phases. The phases are chemically distinct from each other.

As there are two or more phases present in heterogeneous mixtures they can be separated by solvent extraction where in one phase is miscible with the solvent and the other phase is immiscible.

Components of a heterogeneous mixtures are distinctly visible . There are two types of heterogeneous mixtures, the colloids and the suspensions.These two vary with each other with respect to particle size.

Answer:

216 square feet is the volume

Answer:

10%

Explanation:

I think you are looking for mass percent concentration so...

concentration = (mass of solute / total mass of solution) x 100

concentration = (10g of NaCl / (10g of NaCl + 90g of H2O) solution) x 100

concentration = 0.1 x 100

concentration = 10%

Answer:

Concentration of solution is 0.1.

Explanation:

Given data:

Mass of NaCl = 10 g

Mass of water = 90 g

Concentration of solution = ?

Solution:

Formula:

Concentration = mass of solute / total mass of solution

Now we will calculate the total mass of solution:

Total mass of solution = mass of solute + mass of solvent

Total mass of solute = 10 g + 90 g

Total mass of solute = 100 g

Now we will determine the concentration,

C = 10 g/100 g

C = 0.1

Answer:

[tex]V=0.137L[/tex]

Explanation:

Hello.

In this case, since the molarity is computed in terms of the moles of solute (acetic acid) and the volume of the solution in liters, we must first compute the moles of acetic acid by using its molar mass to subsequently compute the volume as follows:

[tex]n=12.35g*\frac{1mol}{60.05g}=0.2057mol[/tex]

[tex]M=\frac{n}{V}\\ \\V=\frac{n}{V}=\frac{0.2057mol}{1.5mol/L}\\ \\V=0.137L[/tex]

Answer:

CaCO3: empirical.

C6H12O6: not empirical.

NaMnO4: empirical.

Ba3(PO4)2: empirical.

K2C2O4: not empirical.

Explanation:

Hello.

In this case, since the empirical formula of a chemical compound is the smallest whole number ratio of atoms of each element in the compound, for each compound we proceed as follows:

CaCO3: it is empirical since the subscripts there cannot be reduced anymore.

C6H12O6: not empirical since the smallest whole number ratio of atoms would be CH2O.

NaMnO4: it is empirical since the subscripts there cannot be reduced anymore.

Ba3(PO4)2: it is empirical since the subscripts there cannot be reduced anymore.

K2C2O4: not empirical since the smallest whole number ratio of atoms would be KCO2.

Best regards.

The chemical formula that are empirical and not empirical are:

A chemical compound's empirical formula is the smallest whole-number ratio of atoms of each element in the compound.

[tex]CaCO_3[/tex]: it is empirical since the subscripts there cannot be reduced anymore.

[tex]C_6H_{12} O_6[/tex]: not empirical since the smallest whole number ratio of atoms would be [tex]CH_2O[/tex]

Answer:

d

Explanation:

the endothermic reaction absorbs heat and exothermic emits heat. If we think of this from increasing the temperature, exothermic already emits heat so it would favor an endothermic reaction. In this instance, a decrease in temperature would do the opposite, which would favor the exothermic reaction.

We define science as the knowledge that seeks to understand truths or natural laws to explain .

In the most specific sense of the word, science is that type of knowledge that seeks to understand truths or natural laws to explain the functioning of things and the universe in general.

The concept of science can be defined as a body of systematized knowledge acquired through observation, identification, research and explanation of certain categories of phenomena and facts, and formulated methodically and rationally.

Answer:

Option B. 4.38 g

Explanation:

The following data were obtained from the question:

Half life (t½) = 20 mins

Original amount (N₀) = 70 g

Time (t) = 80 mins

Amount remaining (N) =.?

Next, we shall determine the decay constant. This can be obtained as illustrated below:

Half life (t½) = 20 mins

Decay constant (K) =.?

Decay constant (K) = 0.693/ half life (t½)

K = 0.693/20

K = 0.03465 min¯¹

Finally, we shall determine the amount remaining after 80 mins as follow:

Original amount (N₀) = 70 g

Time (t) = 80 mins

Decay constant (K) = 0.03465 min¯¹

Amount remaining (N) =.?

Log (N₀/N) = kt/2.303

Log (70/N) = (0.03465 × 80)/2.303

Log (70/N) = 2.772/2.303

Log (70/N) = 1.2036

Take the anti log of 1.2036

70/N = antilog (1.2036)

70/N = 15.98

Cross multiply

70 = N × 15.98

Divide both side by 15.98

N = 70/15.98

N = 4.38 g

Therefore, the amount of the isotope remaining after 80 mins is 4.38 g

-- At any given time, different parts of Earth experience different seasons.

-- At any given time, all parts of Earth experience the same season.  NOT

-- Summer occurs when sunlight reaches the northern or the southern hemisphere directly.

-- Summer Occurs when sunlight reaches the northern or the southern hemisphere indirectly.   NOT

-- When the southern hemisphere is tilted towards the sun, it receives more sunlight, so southern hemisphere experiences summer.

-- Winter occurs when sunlight reaches the northern or the southern hemisphere directly.  NOT

In other words, December in Australia is like June in the central and south USA, Mexico, Guatemala, Nicaragua, El Salvador, Honduras, and Costa Rica.

Different parts of the earth experience different seasons, and the summers are due to the tilt of the axis that causes sunlight to reach the hemisphere.

Seasons are the climatic variation due to the tilted axis of the planet that results in different amounts of sunlight reaching the planet.

The region facing and tilted towards the sun experiences summers as the sun rays are direct towards that region.

As the axis is tilted towards the southern hemisphere then the region will experience the summers season, unlike the northern hemisphere.

Therefore, different parts of the earth undergo different seasons.

Answer:

Electrons fill orbitals in order of increasing orbital energy

Explanation:

Apex

The periodic table consists of elements placed in increasing order of atomic numbers. In the table, electrons fill orbitals in increasing orbital energy. Thus, option A is correct.

The Aufbau principle states the filling of the orbitals and subshells of the atom with the electrons based on the energy levels. The electron occupies the lowest energy level.

The filling of the electron proceeds with an increase in the energy levels or the orbitals that in a periodic table increases from left to right across a horizontal row.

In a period, the number of the subshell or orbitals increases with an increase in the atomic number. The electron fills the higher energy levels after they have completely occupied the low energy levels.

Therefore, in option A. the electrons fill from an increasing order of energy levels.
