Answer:
The metallic elements have more metallic characteristcis.
Explanation:
- Metallic character is the name given to a set of common properties shared by the metallic elements.
- Metallic luster, high density, high electric and thermal conductivity are some physical properties associated with metallic characters.
- Malleability and ductility is also an important metallic characteristic.
- Generally the metals are hard and dense.
- The elements on the left hand side of the periodic table show metallic characteristics except hydrogen.
Answer:
A) vinegar-acidic Baking soda-basic Tomato juice-acidic Sugar-neutral.
Explanation:
Hello,
In this case, it is widely acknowledged that vinegar is a diluted and processed form of acetic acid which is of course acidic as well as tomato juice which has a pH of about 4.2. Baking soda, which is chemically known as sodium bicarbonate has a pH greater than 7, for that is reason it is basic. Finally, sugar, is known by its neutrality, for which its pH is about 7, for that reason it is neutral. In such a way, answer is A) vinegar-acidic Baking soda-basic Tomato juice-acidic Sugar-neutral.

You must first calculate the total weight of 1 mole of the substance. You do this by finding the molar weights on the periodic table of each of the elements in the compound:
So now we take the amount of each element that is given in the compound and divide it by the total mass of the compound:
Carbon: 96.08g
Carbon = 49.48%
Nitrogen: 56.028g
Nitrogen = 28.85%
Oxygen: 31.998g
Oxygen = 16.48%
Nickel and Phospherus . Compound name is Nickel Phosphate
Oxygen was first produced via photosynthesis as ocean microbes evolved in the event that was called the Great Oxidation Event. Therefore the correct answer is C
