T or F
which atom in each pair that has the largest atomic radius.
a. Al or B
b. Na or AI
c. S or o
d. O or F
e. Br or CI
f. Mg or ca
According to the electronic configuration and trends in the periodic table,atom which has largest atomic radius in each pair are Al,Na,S,O,Cl,Ca respectively.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

A student’s experiment showed that her egg gained mass overnight with the vinegar and distilled water. She had about a +1% change for distilled water. She had hypothesized that the egg’s mass would not change significantly with vinegar. She concluded that her hypothesis about vinegar was not supported because it did change in mass. Her teacher told her that the data indicated that her hypothesis was supported, especially with the 10% change for the distilled water. What did the teacher mean?
Answer:
the teacher means that if she had done more research she wouldve had a better result

Which example shows an interaction between the urinary system and the circulatory system?
A. a break in a bone
B. the inhalation of air
C. a bee stinging the skin D. the blood flowing to the kidneys
The blood flowing to the kidneys is an example of interaction between urinary and circulatory system.
What is circulatory system?Circulatory system is a system which consists of heart, blood vessels and blood which is circulated throughout the entire human body. It also includes the cardiovascular system or the vascular system comprising of the heart and blood vessels.
The circulatory system has two divisions :1) systemic circulation 2) pulmonary circulation. The network of blood vessels are large elastic arteries and large veins.Blood is a fluid which consists of plasma ,red blood cells ,white blood cells and platelets which are circulated around the body.
This way oxygen and nutrients are circulated to the tissues. The circulated nutrients include proteins and minerals and gases such as oxygen ,carbon dioxide hormones and hemoglobin which provides nourishment.
It also helps the immune system to fight against diseases and maintain homeostasis by maintaining temperature and pH.

a. _______________________________ at spreading ridges.
b. _______________________________ at convergent margins.
c. _______________________________ at transform faults.
Plates are thin at spreading ridges, plates sink at convergent margins, and plates slide past one another at transform faults. Plate boundaries are borders where two tectonic plates interact with each other.
What are plate boundaries?Plate boundaries can be defined as the borders where two tectonic plates meet and interact with each other.
Geologic activity (e.g., volcanic activity) always occurs at the plate boundaries.
Convergent plate boundaries refer to the place where plates are moving towards one another.
Transform plate boundaries refer to boundaries where the motion is predominantly horizontal.

ok yall l have to write a essay about Pretend that you are the moon. What would you say? Describe yourself to others based on what you have learned about the moon in class. How does your surface reflect light? Do you always look the same? How long does it take you to revolve around the Earth? Do you have an axis like the Earth? Where do you go during the day? What would you see in space?
can yall do it for me
Answer:
If I was the moon, I would say that space is amazing. Past the years, I had been walked on by many people. I think they are called astronauts. The first person that put their feet on me was Neil Armstrong. He had a white thick coat and a helmet. I had been flagged by Buzz Aldrin but, the flag been flat on the ground since the moment Aldrin and Neil Armstrong lifted off. I couldn't do anything about it but, that flag made me feel special. I remember that the flag had about 50 white stars on the corner, in the corner was filled with blue where the stars were, red, white stripes. I shine because my surface reflects light from my friend, the sun. Many people ask me, "Do you always look the same?" No, everyone sees the same phases of me, the moon. I go through a process called moon phases. They are first Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent, New Moon. I rotate on my axis. One rotation takes nearly as much time as one revolution around Earth I believe. During the day, I go the the other side of the earth, where the Earth's shadow is. Honestly, I enjoy being the moon. It's fun and I enjoy the white little twinkling stars beside me. I like seeing that little world move.

which atom in each pair that has the greater electronegativity.
a. Ca or Ga
b. Br or As
c. Li or O
d. Ba or Sr
e. Cl or S
f. O or s
Answer:
A)Ga b)Br c)O d)Sr e)Cl f)O
Explanation:
Electronegativity will decrease the further you go down the periodic table and will increase from left to right. This makes fluorine the most electronegative just for reference.
Ex: Ca and Ga are on the same period but Ga is closer to the right so it’s the most electronegative

Ocean water becomes denser as its salinity increases or its temperature decreases.
In an ecosystem comprising of the oceans, the fact the ocean is a major resource of nutrients is that 100 ml of ocean water contains millions of bacteria and hundreds of thousands of phytoplankton.
What is an ecosystem?
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
