Answer:
To balance the chemical equation, I'll assume the reaction is carried out under standard conditions. Here's the balanced equation:
2 N2 (g) + 5 O2 (g) → 4 H2O (l) + 4 NO3- (aq)
Explanation:
To balance the number of nitrogen (N) atoms, we need 2 nitrogen molecules (N2) on the left side. This gives us a total of 4 nitrogen atoms on the left side.
To balance the number of oxygen (O) atoms, we need 5 oxygen molecules (O2) on the left side. This gives us a total of 10 oxygen atoms on the left side.
On the right side, we need 4 water molecules (H2O) to balance the hydrogen (H) atoms. This gives us a total of 8 hydrogen atoms on the right side.
Finally, to balance the oxygen (O) atoms on the right side, we need 4 nitrate ions (NO3-) since each nitrate ion contains one nitrogen and three oxygen atoms. This gives us a total of 12 oxygen atoms on the right side.
Now the equation is balanced with 4 nitrogen atoms, 10 oxygen atoms, 8 hydrogen atoms, and 4 nitrate ions on both sides.

Is correct! It should be answer(4) or (D)
Answer:
The correct answer is C: A triglyceride
Explanation:
A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms. A carbohydrate is is a synonym of saccharide.
A triglyceride is an ester derived from glycerol and three fatty acids. So not a saccharide. The other 3 options all are saccharides. Triglycerides are the main constituents of body fat.
Triglyceride is not a type of carbohydrate molecule. It's a type of fat found in the blood, while disaccharides, glucose molecules and polysaccharides represent different types of carbohydrates.
Among the choices A. A disaccharide, B. A glucose molecule, C. A triglyceride, and D. A polysaccharide, option C. A triglyceride is NOT a type of carbohydrate molecule. Instead, triglycerides are a type of fat found in the blood. A person's body converts calories it doesn't need for energy into triglycerides. On the other hand, disaccharides, glucose molecules and polysaccharides are all different types of carbohydrates, which are molecules consisting of carbon, hydrogen, and oxygen atoms.

b. follow the instructions on the label
c. keep materials in unlabeled containers
d. use chemicals in well ventilated areas
Answer: C
Explanation:
Keep materials in unlabeled containers
in the atom.
B. Electronegativity increases because there are more valence
electrons in the atom.
C. Electronegativity decreases because the valence electrons are
farther from the nucleus.
D. Electronegativity decreases because the size of the nucleus is
bigger.
Electronegativity decreases because the valence electrons are farther from the nucleus. Hence, option C is correct.
Electronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons toward itself.
From top to bottom down a group, electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.
Important exceptions to the above rules include the noble gases, lanthanides, and actinides.
Electronegativity decreases because the valence electrons are farther from the nucleus. Hence, option C is correct.

B. The nucleus contains protons and neutrons and is orbited by electrons.
C. Protons, neutrons, and electrons occupy the same spaces within the atom.
D. Protons occupy the center of an atom, with neutrons and electrons circling.
Answer:
Explanation:
-Octet forms when the valence electrons are gained, lost or shared.
-In order to become stable, which has 8 valence electrons (octet), nonmetal groups such as group 17, needs to gain 1 more electron to become 8/ octet.
When gaining that 1 electron, group 17 elements become negative ion or anions
-For metal groups such as group 1, they need to lose that 1 electron to become stable. When they lose that 1 electron, they become positive ion which is cation.
Hope this helps
