Answer:
The chemical equation needs to be balanced so that it follows the law of conservation of mass.
Explanation:
Create a hypothesis, design an experiment the list varies really
A mole of any chemical compound contains the same number of molecules - about 6.022 × 10²³ molecules.
So, 1 mole of H₂O₂, 1 mole of C₂H₂ and 1 mole of CO contain the same number of molecules.
Answer:
C.it has a lower melting temperature
Explanation:
A good way to solve this problem may be to think about a simple ionic compound, such as salt, NaCl:
- NaCl easily disolves in water, so options A and B are true about ionic compounds.
- Salt powder does not conduct electricity, however a concentrated solution of salt in water does. Meaning that option D is true as well.
- NaCl has a melting point of 801 °C, not particularly a low value. Thus the correct option is C.
