Answer:
The surface tension of the water
Explanation:
The surface of the water curves down twords the edge of the coin.
Answer:
0.857 atm
Explanation:
The nitrogen stops owing when it fulfills both of the tanks (the gas molecules intend to fulfill all the space they are). So the tanks will have the same pressure, and the final volume will be the volume of the two tanks.
For Boyle's law:
P1*V1 = P2*V2
Where P1 is the initial pressure (3.00 atm), V1 is the initial volume(2.00 L), P2 is the final pressure, and V2 is the final volume (2.00 + 5.00 = 7.00 L).
3.00*2.00 = P2*7.00
7.00P2 = 6.00
P2 = 0.857 atm
We know that the equation for density is:
where D is the density, m is the mass in grams, and V is the volume.
Given two of the variables, we can then solve for density:
Therefore, we now know that the density of the gasoline is 0.833g/mL.
The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties. It also depends on what your doing to the soap
Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water. things burning or exploding. Would be chemical reactions Examples of physical changes include crushing a can, melting an ice cube, and breaking a bottle.
Answer:
1.KCl is answer
Explanation:
when potassium chloride KCl is dissolved in water,it will dissociate to form k+ and cl- .thus,the solute must be k+Cl- .
