Answer:
Mass is a measure of how much matter an object contains, while weight is a measure of the force of gravity on the object. An object has the same composition, and therefore mass, regardless of its location.
Explanation:
<span>its because they're both structured the same way. for example the sun and the nucleus are the same (in the centre) and the electrons and planets orbiting are the same</span>
The answer is C) because,
Not all of them are gases, only dust and smoke are
They do not all make up water, smoke comes from fire
You can find dust is musky air as well
So the answer is C) They are particles in the air
Answer:
A) Network covalent
B) Molecular
C) Ionic
Explanation:
A) Network covalent
This compouds are characterized by having atoms bonded each other by covalent union like a network that extends to all the structure (macromolecule). They have high melting points and low conductivity. A good example of this is diamond.
B) Metallic and network covalent compounds are insoluble in water. Also, ionic compounds that are soluble in water dissociate and conduct electricity.
So, in this case we are talking about a molecular substance in particular, a polar substance.
C) Ionic
This substances dissolved in water conduct electricity. Also they have high boiling points
Answer:
Ca(OH)2 + 2HNO3, → 2H2O+ Ca(NO3)2
