Its actually Q = 103.2 J
Explanation:
Theorists try to find ways to explain human behavior in rational ways. It seems irrational to break rules, if we want to maintain social order. We are largely constrained by the rules and obliged to behave in a particular way or to avoid certain behaviors. What motivates people to break social rules? Do you think powerful and famous people tend to break more rules? Is it worth breaking these rules? No Response(s) Be the first to respond to the Discussion topic!
Answer:
See explanation
Explanation:
According to Burgess (1996); 'We don't break rules because it 'doesn't feel right' to do so. Some elements of personality can determine whether we will break rules or not, particularly when the moral/social-conventional distinction is taken into consideration'.
If an individual has the urge to behave in a manner that transgresses social rules, personality characteristics now come into play here. Personality traits determines whether the individual considers him/herself as bound by the rules. Some people will follow the rules absolutely while some only follow rules that they consider important, a small proportion will not follow any rule that prevents them from achieving their set objectives.
Famous people become carried away with affluence and position and tend to break more rules since they believe that they will always get away with it because of whom they are.
Irrespective of the circumstances, it is never worth it to break a rule. We always have to see ourselves as bound by rules as part of our social responsibility.
What is true about the formation of a bond?
Answer:
There is an overall release of energy when bonds form.
Explanation:
There is a general release of energy when bonds form. This energy is called bond energy.
Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.
What is the significance of an electronegativity difference of 1.7 between 2
atoms?
O A. It tells which atoms form positive ions and which atoms form
negative ions.
OB. It represents the boundary between what is considered to be an
ionic or a covalent bond.
C. It determines if the 2 atoms will react to form a molecule.
D. It identifies which metal atoms will join together to form metallic
bonds
Am
B. It represents the boundary between what is considered to be an ionic or a covalent bond.
Further explanationElectronegativity is the ability of atoms to attract electrons, especially in covalent bonds (sharing of electron pairs)
In a periodic system, electronegativity increases in a group, from bottom to top, and in a period from left to right.
From this difference in electronegativity, we can determine the ionic compound, polar or non-polar
Pauling determined the electronegativity scale (based on bond energies), between 0.7 - 4 (Fluorine has the highest number of electronegativities: 4)
Polar covalent compounds have a large electronegativity difference, while nonpolar compounds have a small electronegativity difference.
We can use the difference in electronegativity between the 2 bonded atoms to determine their polarity
<0.5: covalent non polar 0.5- 1.7: covalent polar > 1.7 : ionExample
H₂OH = 2.1
O = 3.5
H₂O = 3.5-2.1 = 1.4 >> polar
O₂= 3.5-3.5 = 0 >> non polar
Calculate the enthalpy change to raise the temperature of 180.0 g of water from 10.0°C to 40.0°C. The molar heat capacity for water is 75.3 J/Kmol. a. What values have you been given? b. What value are you trying to find? c. Which heat equation do you need? d. Now solve the problem.
Answer:
22572J
Explanation:
a) The following values have been given:
Mass of water = 180.0g
Initial temperature = 10°C
Final temperature = 40°C
molar heat capacity for water = 75.3J/Kmol
To calculate the specific heat capacity of water (c), we divide the molar heat capacity by molar mass of water (18g/mol)
That is; 75.3/18
= 4.183 Jg/K
b) The enthalpy change denoted by ∆H is the value we are trying to find.
c) To find enthalpy change (∆H), we use the formula:
∆H = m × c × ∆T
Where; m= mass
c= specific heat capacity
∆T= change in temperature =
(final temp - initial temp)
∆H = m × c × ∆T
∆H = 180 × 4.18 × (40-10)
∆H = 180 × 4.18 × 30
∆H = 22572J
Question
What causes a water molecule to be polar?
A. The Oxygen atom is larger and stronger than the Hydrogen atoms so the electrons spend more of their time nearer the hydrogen
B. The Oxygen atom is smaller and weaker than the Hydrogen atoms so the electrons spend more of their time nearer the oxygen
C. The Oxygen atom is smaller and weaker than the Hydrogen atoms so the electrons spend more of their time nearer the hydrogen
D.The Oxygen atom is larger and stronger than the Hydrogen atoms so the electrons spend more of their time nearer the oxygen
Answer:
The correct option is D
Explanation:
Water molecules are polar because there structures are made up two sides; the positively charged side (the hydrogen side) and the negatively charged side (the oxygen side). The atoms in the water molecule are joined together by covalent bond - meaning there is sharing of electrons between the constituent atoms. The oxygen atom is bigger/larger (in size) and has a higher electronegativity (ability to attract electrons) hence, the electrons tend to spend more time around the oxygen than the hydrogen atom.
What does analyzing data involve?
A. Comparing trends or patterns that prove the hypothesis
B. Observing an experiment to collect data
C. Creating a hypothesis to answer a question
D. Forming a hypothesis to develop an experiment
Answer:
A. Comparing trends or patterns that prove the hypothesis
Explanation:
Analyzing data involves comparing trends or patterns that prove the hypothesis. Sometimes, the trend might invalidate the hypothesis.
Data analysis is a very important process in course of experimentation. It brings out the meaning of data and makes data useful. Analysis involves establishing patterns from a given set of data. The main aim of data analysis is to identify useful information. It usually entails cleansing and transforming data into a set that can be useful.Ernest Rutherford's discovery led to the understanding that atoms consist mostly of empty space with

How does density affect the water cycle
Explanation:
Biological in the ocean is affected by the water cycle via the Mixed Layer Depth and Run off from land. Salinity and temperature determine the density of ocean water, and density influences the circulation. E-P determines surface salinity of the ocean, which helps determine the stability of the water column.

Identify the property of the matter described below.
Alcohol floats on top of the water.
A-pH
B-conductivity
C-density
D-luster
Answer: C.
Explanation: Alcohol floats on oil and water sinks in oil. Water, alcohol, and oil layer well because of their densities, but also because the oil layer does not dissolve in either liquid. The oil keeps the water and alcohol separated so that they do not dissolve in one another. ... Water sinks because it is more dense than oil.

348 g of water starting at 4.0°Celsius is heated until his temperature is 37°Celsius. Calculate the amount of heat energy needed to cause this rise in temperature
STEP BY STEP EXPLANATION!!
Answer:
48.049 kJ or 48049 J
Explanation:
Hello again.
So we know the formula [tex]q = mc\Delta t[/tex]. c is the heat capacity but this time, it is not given. However, water has a very well known heat capacity which is 4.184 J/(g°C). This is in fact the number we refer to a calorie which is the amount of energy you burn that can raise the temperature of 1g of water by 1°C. So, plugging in values, you get the above. But double check if I am wrong.
The amount of heat energy needed to cause this rise in temperature is 48.049 kJ or 48049 J.
What is heat energy?Heat is the energy that moves from one body to another when temperatures are different. Heat passes from the hotter to the colder body when two bodies with different temperatures are brought together.
A given amount of matter's heat capacity is the amount of energy needed to raise its temperature by one degree Celsius.
The heat energy will be calculated by the formula
Q = m•C•ΔT
Where c is the heat capacity.
The m is the mass
T is the time
Mass is 348 grams
Temperature is 37°C
The change in temperature is 4.0°C to 37°C
The heat capacity of water is 4.184
Q = 348 x 4.184 x -33 = 48049.056.
Therefore, the amount of heat energy needed is 48.049 kJ or 48049 J.
