Explanation:
systemic and pulmonary circulation differ from each other because the pulmonary circulation is part of the circulatory system responsible for forming a circuit of vessels that transport blood between the heart and lungs, and systemic circulation, on the other hand, forms a closed circuit between the heart and the rest of the body.
I hope this helped, and hopefully u give me brainliest, ask any questions if u need anything :)
Answer:
8 moles = 16 gm of H2 left over
Explanation:
The balanced equation is
2 H2 + O2 ===> 2 H2 O
20 g H2 = 20 g / 2 gm/mole = 10 moles of H2
32 g O2 = 32g / 32 g / mole = 1 mole O2
From the balanced equation, you can see each 2 moles of H2 requires 1 Mole of O2
you would need 20 moles of O 2 to react withe the 10 moles of H2
but you only have 1 mole of O2 so 8 moles of H2 will be left
Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.
Explanation:
If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.
If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.
If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.
The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of 
molecule is as follows.
As the electronegativity difference is 0 which is less than 0.4.
Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.
Answer:
White school glue is liquid because its long polymers can slide over and along one another. It does not flow easily, though; it is quite viscous. The addition of some chemicals—such as a borax solution (or sodium tetraborate decahydrate dissolved in water)—can cause cross-links to form between the polymers.
