The answer is volume, in gasses, volume depends on the matter, but in solids, volume can be measured.
The ph value of water is 7 but a salt which is derived from a weak acid will be less than 7 and a salt which is derived from a base will be above 7.
Answer:
Soil provides nutrients, water, and minerals for plants and trees, stores carbon, and is home to billions of insects, small animals, bacteria, and many other microorganisms.
Answer:
A - NaCl is a product
D - Cl2 is a gas
Explanation:
Based on the chemical reaction;
2Na(s) + Cl2(g) → 2NaCl2
- Sodium metal reacts with chlorine gas to form sodium chloride. Sodium is in solid state, chlorine is in gaseous state and Sodium chloride is in solid state.
- In the chemical reaction, sodium and chlorine are reactants while sodium chloride is the product.
- Additionally the chemical reaction above is balanced so as to obey the law of conservation of mass.
The answer is , C. Both the atomic mass and the atomic number increase from left to right .
