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
(I accidentally posted in comments first so ignore that)
To find S, the number of shared
electrons, recall that
S = N-A
What is S for silicon
tetrachloride, SiCl4?
Answer:
I'm rly confused but Si stands for silicon in the compound if that's what ur asking
hope it helps tho
How can a large body of water, such as an ocean, influence climate?
There is no influence on climate from an ocean.
Ocean winds can carry moisture with them and can bring rain and fog over inland areas.
Warm ocean air causes a dry climate.
Rushing water from tides cools the land.

how does the respiratory system aid the digestive system
a. the lungs take in oxygen to aid in food digestion
b.the lungs take in carbon dioxide to aid in food digestion
c. the expand the diaphragm, which helps to push the stomach during digestion
d. the lungs contract the diaphragm, which helps to push the stomach during digestion
PLEASE HELP ASAP ! :)
Answer:
The respiratory and digestive systems work together to power the body. A properly functioning respiratory system delivers adequate oxygen to the blood. Because the digestive system breaks down food and uses muscular contractions to move food through the digestive tract, it needs oxygen to function properly.

Please help me out with this question if you help me I will give you the brain thing and extra points. 5/9 image below.
Answer:
Third Law of motion. (answer C)
Explanation:
This is an example of Newton's Third Law of motion which normally translates into Action/Reaction. That is : the expelled air exerts a force in the direction opposite to that of the motion of the air that goes out. It is the same as propulsion in a rocket.

What three things happen to plates at the plate boundaries (where two or more plates come together)?
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.

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.

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.
