Answer is: <span>c.VIIA.
</span>In VIIA or group 17 (hologen elements) there are six elements: fluorine<span> (F), </span>chlorine<span> (Cl), </span>bromine<span> (Br), </span>iodine<span> (I), </span>astatine<span> (At).and </span>tennessin(<span>Ts).
</span><span>They have high electronegativity because they have seven valence electrons in their outermost energy level, so they can gain an electron to have the </span>octet rule<span>. </span>
Electronegativity<span> is
a chemical property that
describes the tendency of an atom to
attract a shared pair of electrons towards
itself.

Answer:
The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the products
Explanation:
The expression that best describes this reaction is that the same amount of carbon will be found in the reactants as in the products.
During the process of photosynthesis, carbon dioxide combines with water using solar energy to produce glucose and oxygen.
It can expressed as depicted below:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
To validate our choice;
This is a balanced chemical equation:
6 moles of carbon is found on the reactant side and also, 6 mole of carbon on the product side.
But Glucose is not found on both sides of the expression
the water wants to give the electricity to you because it doesn't want any more electrons it throws them away and gives them to your body
Answer:
Tincture of iodine, iodine tincture, or weak iodine solution is an antiseptic. It is usually 2–7% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water. Tincture solutions are characterized by the presence of alcohol.
