Answer:

chloroplast

Explanation:

The mass of one electron : 9.103 x 10⁻²⁸ g

Electrons are a part of the atomic nucleus particles (including protons and neutrons), and are negatively charged (-1)

An electron has the charge of  -1.6022 x 10⁻¹⁹C

1 g =  -1.76 x 10⁸ C

so the mass of one electron :

[tex]\tt \dfrac{1.6022\times 10^{-19}}{1.76\times 10^8}=9.103\times 10^{-28}~g[/tex]

Answer:

Electrons

Explanation:

When determining the chemical properties of elements, the most important subatomic particle to consider is the electrons.

Electrons are negatively charged particles that orbits an atom. They occupy the extranuclear space of an atom.

These electrons determines the chemical properties of each atom. Most especially, the valence ones. All elements wants to resemble the noble gases, so they alter their number of electrons in order to attain this stable state.

A) 4400 kj of heat released into surroundings

Reaction

C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O, the ∆H is –2200 kJ

Reaction exothermic( ∆H=-, released heat to surrounding) and for combustion of 1 mole of C3H8

So for two moles of C3H8, the enthalpy :

[tex]\tt -2200\times 2=-4400~kJ[/tex]

Answer:

Answer:

when elements from A bond with elements from B

Explanation:

The elements in part A are metals and that of B are non-metals. Ionic bonds are formed between metals and non-metals. Thus option b is correct.

An ionic bond is  formed between a metal and non-metal through loss of electron from the metal to the non-metal. Metals are electron rich and easily loss electrons.

Non-metals are electronegative and they are electron -deficient. They need to gain electrons to attain stability. Therefore non-metals such as oxygen, nitrogen, carbon etc. bonds with metals by gaining electrons from metals.

The positive charge of metal acquired by loss of electron and negative charge of nonmetals acquired by gain of electron attracts electrostatically and form the ionic bond.

The elements from A thus bonds ionically with elements from B.

Answer:

C

Explanation:

Answer:

The final temperature of the water = 45°C

Explanation:

Heat lost = heat gained

Heat lost by water at 60°C = m₁CΔT₁

Heat gained by water at 25°C = m₂CΔT₂

where m₁ is mass of water at 60°C  = 100.0 g; m₂ is mass of water at 25°C = 75.0 g

C, specific heat capacity of water = 4.18 J/g°C

ΔT₁ = (60 - T); ΔT₂ = (T - 25); T = final temperature of the water

m₁CΔT₁ = m₂CΔT₂

100 * C * (60 - T) = 75 * C * (T - 25)

-100T + 6000 = 75T - 1875

-(100T + 75T) = -(6000 + 1875)

175T = 7875

T = 45°C

Therefore, final temperature of the water = 45°C

Answer:

121.8bar

Explanation:

The partial pressure is the pressure a gas would exert if it were alone in the volume of the gas mixture;

 Given parameters:

  Total pressure  = 2558psi

   Partial pressure of carbon dioxide  = 54.6bar

Unknown:

Partial pressure of nitrogen dioxide gas  = ?

Solution:

  Total pressure = partial pressure of carbon dioxide + partial pressure of nitrogen dioxide gas

Let us convert from psi to bar;

           14.504psi  = 1 bar

           2558psi  = [tex]\frac{2558}{14.504}[/tex]   = 176.37bar

Now;

Partial pressure of nitrogen oxide = 176.37bar  - 54.6bar  = 121.8bar

Answer:

1766 psi

Explanation:

The first step is to convert 54.6 bar into psi units, which is aproximately 791.9 psi. Next, subtract that from 2558 psi and you will get about 1766 psi.

Given parameters:

Molarity of KCN  = 0.025M

Number of moles  = 8.84 x 10⁻³mol

Unknown:

Volume of KCN  = ?

Solution:

The molarity of a substance is expressed as;

       Molarity  = [tex]\frac{number of moles }{volume }[/tex]  

 Volume of KCN   = [tex]\frac{number of moles }{molarity}[/tex]

Now insert the parameters and solve;

  Volume of KCN  = [tex]\frac{0.00884}{0.025}[/tex]   = 0.354L

Answer:

The time of heating

Explanation:

Let us analyse the experiment closely; the temperature of the liquid increases as the time of heating increases. This implies that the temperature of the liquid is dependent on the time of heating of the liquid. The longer the time of heating, the greater the increase in temperature until the boiling temperature is eventually attained.

Hence, the temperature of the liquid is the dependent variable, the time of heating is the independent variable when the heating rate is held constant.

Answer:

T(K) = 373.15 K

Explanation:

The kelvin is the base unit of temperature in the International System of Units (SI). The symbol used to express temperature in kelvins is K.

The temperature of zero kelvins is called the absolute zero. It is considered to be the lowest possible temperature, although nothing has reached it. The absolute zero (0K) is - 273.15 degrees Celsius.

This is the equation we can use to solve this question:

 [tex]T(K) = T(C) + 273.15[/tex]

We have 100*C.

[tex]T(C) = 100 C[/tex]

[tex]T(K) = 100C + 273.15[/tex]

[tex]T(K) = 373.15 K[/tex]

Explanation:

Many of the properties of organic molecules can be predicted based on the strength of their cohesive molecule-molecule interactions (i.e. how much the molecules want to stick together).  The boiling point (BP) and melting point (MP) of an organic molecule is related to: 1) the molecular weight of the molecule and 2) the "stickiness" of individual molecules for their neighbors.  

   For example, molecules in a liquid are held together by attractive interactions between molecules.  These interactions must be broken (by adding heat) in order to transition into the gas.  The stronger the cohesive interactions, the more heat that is necessary for the liquid-to-gas phase transition.  These same attractive molecule-molecule interactions have to be broken for a solid to liquid phase change.

Examples: (Rank the following molecules in terms of MP and BP.)

Introduction to intermolecular forces:

All of the attractive intermolecular forces are based on the electrostatic attraction of positive charges on one molecule with negative changes.  The stronger the charges, the stronger the attraction between molecules.

How to:

In general, comparisons can only be made between molecules with similar formulas or molecular weights.*  First, identify the functional groups in the molecules being compared.  Each functional group can form different types of intermolecular interactions (see the chart above).  Interactions higher up on the chart form stronger cohesive interactions and will have higher boiling points and melting points.

* Note that larger molecules usually have higher boiling points and melting points.  This is not because of their higher molecular weights but because they usually have greater surface areas with which to form more intermolecular interactions.  This is also why linear molecules tend to have higher MPs and BPs than branched (or more spherically shaped) molecules.  Linear molecules will have more surface area than a more spherically shaped molecule.

All three molecules have approximately the same molecular formula and molecular weights.  Only molecule A contains a strongly polarized or ionic functional group: an aldehyde.  The C=O group in aldehydes generate a strong molecular dipole (partial + and - charges).  Thus, it can form weak attractive dipole-dipole interactions, and A will have the highest boiling point and highest melting point in this series of compounds.

Molecules B and C are alkanes.  They can only form the weakest attractive dispersion interactions between their molecular surfaces.  Due to its long-thin shape, B will have a greater surface area and can form more dispersion interactions than the rounder C.  Therefore, B will have a higher boiling point and melting point than C.

Molecule A is ionic (it has charges).  Therefore, it can form the strongest ion-ion interactions and will have the highest boiling point and melting point.

Molecule B is a carboxylic acid with an acidic proton and basic lone pairs.  Therefore, it can form medium strength hydrogen bonding interactions, and it will have the next highest boiling point and melting point.

Molecule C is a carboxylic ester, which is a polar functional group.  However, it does not have an acidic proton.  Therefore, esters cannot form hydrogen bonds with themselves.  Instead, they can only form weak dipole-dipole interactions and will have the lowest boiling point and melting point in this series of compounds.

Answer:

Explanation:

By thinking about non covalent intermolecular interactions, we can also predict relative melting points. All of the same principles apply: stronger intermolecular interactions result in a higher melting point.
