what is known as electronegativity and mention how the electro negativity vary long the periods and down the groups..please i need answers quickly!
Answers
Answer:
Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.
See below and attached image fir answer
Explanation:
Before I go on, I want to bring up that it's not just electronegativity that is affected as you go across a period or up and down a group. Ionization energy and atomic radius also fluctuate.
Here's a diagram:

As you can see, electronegativity increases as you go across a period, while electronegativity decreases as you go down a group. However, if this is true (which it is), we can also say many other factors occur, such as:
As you go across a period from left to right, electronegativity increases, ionization energy increases, and atomic radius decreases. In order for energy to increase, radius must decrease.
As you go up and down a period, electronegativity decreases, ionization energy decreases, and atomic radius increases. In order for energy to decrease, radius must increase.
Electronegativity is the force/energy required to acquire electrons and form negative ions during chemical reactions. (definition credit: from my computers dictionary).
Ionization Energy is the complete opposite. Ionization is the force/energy required to remove electrons from an ion. These strive to make cations while electronegative ions usually involve anions (hence the phrase electronegativity).

Ingrid drew a diagram to compare two ways in which biodiversity can be protected.
Which label belongs in the area marked Y?
has the goal of releasing animals in the wild
is often done in nature preserves
usually protects entire ecosystems
focuses on increasing the population of a single species
Answers
Answer:
The answer is often done in nature preserves
Explanation:
The region Y in the diagram represents the action that is is often done in nature preserves. Hence, option b is correct.
What are the ways of biodiversity protection?Captive breeding and habitat preservation are two important ways to protect biodiversity. Captive breeding involves the capture and breeding of endangered species in a controlled environment to increase their population size.
This method is used for species that are in danger of extinction in the wild due to factors such as habitat destruction, poaching, and disease. By breeding the species in captivity, the population can be increased and eventually released back into the wild to help restore the species' population.
Habitat preservation, on the other hand, involves protecting natural habitats from human activities such as logging, mining, and urban development.
By preserving habitats, the native species that rely on these habitats can continue to live and thrive, maintaining a healthy ecosystem. This is crucial for the conservation of biodiversity, as many species are dependent on specific habitats for their survival.
Hence, option b is correct.

Which of the following best describes what must have happened in the past in an area with a large petroleum trap?
A.
Organic matter must have been buried and placed under intense heat and pressure until it became petroleum. Then, the petroleum must have collected inside an impermeable underground rock formation.
B.
Organic matter must have been exposed to intensely cold temperatures until it became petroleum. Then, the petroleum must have moved up to the Earth's surface through permeable underground rock formations.
C.
Permeable underground rock formations must have allowed the movement of organic matter deep into the Earth. Then, the organic matter must have been exposed to freezing temperatures until it formed petroleum.
D.
Impermeable underground rock formations must have blocked the movement of organic matter through the Earth's surface. Then, the organic matter must have decomposed to form petroleum inside the rock formations.

A. Adding another bulb will make the two of them light a little less brighter since the electrical flow is divided into two making them work.
B. There is a possibility that the flow of electricity maybe little due to the thickness of the wire. There could also be a rise in the temperature of the cell and the bulb.
C. The Bulb will shine brighter because of the extra power or electricity provided! Also, if the voltage is too much, expect the bulb to burn out or sadly, explode.

1. Breakfast Food Company A conducts a research experiment that shows that one of their products, Cereal A, is much healthier than cereals made by other companies. Is this an example confirmation bias? Why or why not?
2. John wants to test sports drinks to find the best one to drink during the soccer season. Every day after practice, John drinks a different sports drink and writes down how good it tastes. At the end of the week, he looks at his data and finds that Sports Drink A is the best. Is this confirmation bias? Why or why not?
Answers
Answer:
1. It is confirmation bias because the company conducted a research experiment on their on products. They could have implemented or changed variables that are part of the experiment in order to get the results they would want. It is best to have a third party that don’t work for the company in order to conduct the experiment without biases
2. For this one it could be both yes and no. It could be that John really enjoyed Sports Drink A, so he purposely wrote down the data for the other drink lower. Here he was bias towards what he wants to have a better outcome. Maybe the sport drink A is from a company he likes many of their products. In order to not have confirmation bias, john should get a friend to give him the drinks without the labels, and the drinks should be the same color. That way he only tests the taste and not the way it looks. Both packaging and the color of the drink.
