It's particles are proton , electron and neutron.
Answer:
The correct formula is the first one.
Explanation:
Copper has two valences I and II, in this example, it's mentioned that copper's valence is I.
Then we have to look in all the formulas for one formula where copper has that valence, and that valence is in formula 1 and 3. Number 4 is discarted that formula is incorrect, that formula doesn't exist.
Number 2 is also discarted because in this formula Cu has a valence of 2.
Number three is discarted because here Bromide has a valence of 2 and that is incorrect, Bromide's valence is 1.
Answer: Blood primarily moves in the veins by the rhythmic movement of smooth muscle in the vessel wall and by the action of the skeletal muscle as the body moves. Because most veins must move blood against the pull of gravity, blood is prevented from flowing backward in the veins by one-way valves.
Good luck !

Explanation:
Density is a property of an object or substance that can be described through the correlation of the mass of an object over its volume.
Mathematically, density = mass / volume.
In description, the relationship of density and mass is positively correlated and with volume, inversely.
Since density and mass is positively correlated then if you increase the mass, the density of the object will also increase leaving density and volume the same.
Example:
Mass = 10 g changes to 20
Volume = 5 cm3
Density =?
1. D = m / v
2. D = 10 g / 5 cm3
3. D = 2 g / cm3
4. D = 20 g / 5 cm3
5. D = 4g/cm3
