Answer:

B. an inner layer is needed because phospholipids always form bilayers.

Explanation:

Lipids are organic compounds which are not soluble in water but they are soluble in organic compounds. They are formed in body by combination of various molecules. The inner layer of phospholipids always form bilayers.

Explanation:

Answer:

A. There is more dissolved oxygen in colder waters than in warm water.

D. If ocean temperature rise, then the risk to the fish population increases.

Explanation:

Conclusion that can be drawn from the two facts stated above:

*Dissolved oxygen is essential nutrient for fish survival in their aquatic habitat.

*Dissolved oxygen would decrease as the temperature of aquatic habit rises, and vice versa.

*Fishes, therefore, would thrive best in colder waters than warmer waters.

The following are scenarios that can be explained by the facts given and conclusions arrived:

A. There is more dissolved oxygen in colder waters than in warm water (solubility of gases decreases with increase in temperature)

D. If ocean temperature rise, then the risk to the fish population increases (fishes will thrive best in colder waters where dissolved oxygen is readily available).

Answer:

solid is definite volume and shape

liquid is a definite volume but not a definite shape because it can move around and fit into different shapes, like on different water bottles.

gas is not a definite volume and not a definite shape because gas particles can expand and spread out which affects both volume and shape

Answer:

3.6 ×10^23

Explanation:

moles = mass/ molar mass

molar mass= (1×32) +(3×16)= 80

moles = 48/ 80

=0.6

moles = number of molecules/ 6×10^23

number of molecules = moles × 6×10^23

=0.6 × 6×10^23

=3.6 ×10^23

Answer:

(i) Protons, Neutrons

(ii) Mass number = 15

(iii) Atomic number = 12

(iv) Neutrons present in the atom = 17

(v) Nuclear symbol for the silicon isotope with mass number, A = 29 is ²⁹₁₄Si

Explanation:

(i) An atom is composed of three fundamental sub-particles: electrons, protons and neutrons. Electrons are found in orbits or energy levels some distance away from The nucleus of the atom. The nucleus of an atom contains the protons and neutrons which accounts for the mass of the atom.

(ii) The mass number of an atom of an element is the sum of the protons and neutrons present jn the nucleus of the atom.

The mass number of an atom of oxygen with proton or atomic number 8 and neutron number 7 is 8 + 7 = 15

(iii) Atomic number of an atom of an element is equal to the number of protons in the atom of the element.

Mass number = proton number + neutron number

Proton number = mass number - proton number

Proton number = 25 - 13 = 12

(iv) In the atom of sulfur represented bymthe symbol, the number in superscript is the mass number A, and the number in subscript is the atomic number Z.

Mass number = proton number + neutron number

Neutron number = Mass number - proton number

Neutron number = 33 - 16 = 17

(v) The nuclear symbol for the silicon isotope with mass number, A = 29 is ²⁹₁₄Si

Where the number in superscript is the mass number A, and the number in subscript is the atomic number Z.

Answer:

What happens when one adds (NH4)2S to a solution that contains Al3+?

Explanation:

The chemical equation for the reaction is shown below:

[tex]3(NH_{4})_{2} S(aq)+2 Al^{3+}(aq) -> Al_{2} S_3} (s) +3 NH_{4}^{+}[/tex]

Answer:

Temperature.

Explanation:

Kinetic molecular theory of gases states that gas particles exhibit a perfectly elastic collision and are constantly in motion.

According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on temperature.

This ultimately implies that, the average kinetic energy of gas particles is directly proportional to the absolute temperature of an ideal gas. Thus, an increase in the average kinetic energy of gas particles would cause an increase in the absolute temperature of an ideal gas.

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Answer:

The atoms present at the beginning of the reaction is equal to the atoms present at the end of the reaction. This is because matter can neither be created nor be destroyed in an ordinary chemical reaction.

Explanation:

During photosynthesis, 6 molecules of water react with 6 molecules of carbon dioxide to form 1 molecule of glucose and 6 molecules of oxygen. The equation for the photosynthesis reaction is

6CO2 + 6H2O --> C6H12O6 + 6O2

At the beginning of the reaction, there is 6 carbon atoms, 18 oxygen atoms and 12 hydrogen atoms while at the end of the reaction, there is 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms.  This is because according to the law of conservation of mass and matter, it can neither be created nor be destroyed in an ordinary chemical reaction. The number of atoms present at the beginning of the reaction must be equal to the number of atoms present at the end of the reaction.

Answer: The pH of the solution is 13.

Explanation:

pOH is defined as the negative logarithm of hydroxide ion concentration present in the solution.

[tex]pOH=-\log [OH^-][/tex]

We are given:

Concentration of [tex]Ca(OH)_2=0.05mol/dm^3=0.5mol/L[/tex]          (Conversion factor: [tex]1L = 1dm^3[/tex] )

1 mole of calcium hydroxide produces 1 mole of calcium ions and 2 moles of hydroxide ions

Concentration of [tex]OH^-=(2\times 0.05)=0.1mol/L[/tex]

Putting values in above equation, we get:

[tex]pOH=-\log (0.1)\\\\pOH=1[/tex]

We know:

[tex]pH+pOH=14\\\\pH=14-1\\\\pH=13[/tex]

Hence, the pH of the solution is 13.

Answer: b

Explanation:

I took the test

The correct answer is LiOH and Li2SO4.

A strong acid is neutralized by a strong base to yield a normal salt.

A neutralization reaction is a reaction between an acid and a base to yield salt and water only.

An acid can be strong or weak. A base can also be strong or weak.  "Strong" or "weak" has to do with the extent of ionization of the acid or base in water. Usually, a strong acid is neutralized by a strong base.

Since H2SO4 is a strong acid, it will require a strong base such as LiOH to neutralize it and the product will be the normal salt Li2SO4.

Answer:

[tex] 0.03 g_{acid}/g_{charcoal} [/tex]

Explanation:

The amount adsorbed (solute) is the acetic acid, and the adsorbent is the activated charcoal. The mass of the adsorbent is 10 g.

So, we need to calculate the mass of the acetic acid as follows:

[tex] m = n*M = C*V*M [/tex]

Where:

n: is the number of moles = C*V

M: is the molecular mass =  60.052 g/mol

C: is the final concentration of the acid = 0.5*0.2 mol/L = 0.10 mol/L

V: is the volume = 50 ml = 0.050 L

[tex] m_{acid} = C*V*M = 0.10 mol/L*0.050 L*60.052 g/mol = 0.30 g [/tex]

Now, the amount of solute adsorbed per gram of the adsorbent is:

[tex] \frac{m_{acid}}{m_{charcoal}} = \frac{0.30 g}{10 g} = 0.03 g_{acid}/g_{charcoal} [/tex]

Therefore, the amount of solute adsorbed per gram of the adsorbent is 0.03 g/g.

b. Al(s) + Cl₂(g) → AICI₃(s)

1. We will balance Cl atoms by multiplying Cl₂ by 3/2.

Al(s) + 3/2 Cl₂(g) → AICI₃(s)

c. NaOH(s) + H₂SO₄(ac) → Na₂SO₄(ac) + H₂O(l)

1. We will balance Na atoms by multiplying NaOH by 2.

2. We will balance H and O atoms by multiplying H₂O by 2.

2 NaOH(s) + H₂SO₄(ac) → Na₂SO₄(ac) + 2 H₂O(l)

d. C₃H₈(g) + O₂(g) → CO₂(g) +  H₂O(g)

1. We will balance C atoms by multiplying CO₂ by 3.

2. We will balance H atoms by multiplying H₂O by 4.

3. We will balance O atoms by multiplying O₂ by 5.

C₃H₈(g) + 5 O₂(g) → 3 CO₂(g) +  4 H₂O(g)

Answer:

CH3CH2CH2CH3

Explanation:

The boiling point of a compound depends on the nature of intermolecular interaction between the molecules of the compound.

If a molecule is nonpolar and has a low molecular mass, then its molecules are most likely held together only by weak intermolecular bonds such as dispersion forces. These forces are easily broken and the molecules move apart hence the molecule possess a low boiling point.

Polar molecules and molecules having higher molecular mass tend to have higher boiling points.

Among all the compounds listed, CH3CH2CH2CH3 is non polar and has the lowest molecular mass hence it exhibits the least boiling point.
