Stating the difference between covalent and ionic bonding....

ionic bonds consist of the transfer of electrons, and covalent consists of the sharing of electrons.

This being said..answer choices A and B are out of the picture.

Thus, answer choice C is your answer.

Involve the attraction of opposite charges;require same amount of energy to break their bonds.

Leah is trying to determine how music affects the growth of plants. She hypothesizes that classical music will cause a plant to
Pani-rosa [81]
Leah's experiment:
A. Takes careful and regular measurements (she measures the growth every day)
B. Has a specific hypothesis and a controlled experiment (the music is the only changing variable, the growth conditions are identical, and this is what she wants to test in her hypothesis)
C. Experimental data that can be recorded and analyzed (measuring the growth of plant fits this)

So the answer must be D, since there is no mention of past research that scientists have found on this topic.

Calculate the work (kJ) done during a reaction in which the internal volume expands from 20 L to 43 L against an outside pressur
Alenkinab [10]

Answer:

\large \boxed{\text{-10.0 kJ}}

Explanation:

1. Calculate the work

w = - pΔV = -4.3 atm × (43 L - 20 L) = -4.3 × 23 L·atm = -98.9 L·atm

2. Convert litre-atmospheres to joules

w = \text{-98.9 L\cdot$atm } \times \dfrac{\text{101.3 J}}{\text{1 L$\cdot$atm }} = \text{-10000 J} = \textbf{-10.0 kJ}\\\\\text{The work done is $\large \boxed{\textbf{-10.0 kJ}}$}

The negative sign indicates that the work was done against the surroundings.

How many liters of water can be formed if 1.65 liters of ethylene are consumed
alexandr1967 [171]
Ethylene Burns in the presence of O₂ to produce CO₂ and H₂O vapors;

                               C₂H₄  +  3 O₂   →   2 CO₂  +  2 H₂O

According to equation, 

22.4 L (1 mole) C₂H₄ reacts completely to produce  =  44.8 L (2 moles) of H₂O

So, 

1.65 L of C₂H₄ on complete reaction will produce  =  X L of H₂O

Solving for X,

                                  X  =  (1.65 L × 44.8 L) ÷ 22.4 L

                                  X  =  3.3 L of H₂O

Rank the following in order of decreasing acid strength in aqueous solution: HCl, HOCl, HOBr,HOI.
I am Lyosha [343]

Answer:

A) HCl > HClO > HBrO > HIO

Explanation:

The strength of an acid is related to the acid dissociation constant (Ka). This is the equilibrium constant for an acid. The higher the Ka, the stronger the acid.

An easier way to compare the strength of acids is through their pKa, where

pKa = -log Ka

The lower the pKa, the stronger the acid.

Let's consider the following acids and their pKa values:

HCl      -7

HClO   7.54

HBrO   8.62

HIO      10.64

The order of decreasing acid strength is:

A) HCl > HClO > HBrO > HIO
