The correct answer of the given question above would be option B. The one that is responsible for capillary action which is a property of liquids is called the cohesive forces. By definition, cohesive force is the intermolecular bonding of a substance where its mutual attractiveness forces them to maintain a certain shape of the liquid. Hope this answer helps.

Answer:

e. two of these choices are correct (b) cohesive and c) adhesive)

Explanation:

Capillary action is essentially the rise of liquids through a narrow tube (region) called as a capillary. There are several forces that come into play in the context of capillary action.

If we consider a liquid like for example, water, then the cohesive forces are responsible for holding the water molecules together (intermolecular attractive force) while the adhesive forces acts between the water molecule and the walls of the capillary (force of attraction between unlike molecules). Surface tension can be defined as the energy required to increase the surface area of a liquid due to the cohesive forces. When adhesive forces become greater than the cohesive forces, the liquid tends to rise up a narrow tube . Thus, both adhesive and cohesive forces are responsible for capillary action.

Where is the ion charge located in the isotope symbol

Juliette [100K]

The ion charge located in the isotope symbol on the top right corner. The number part of an isotope's name is the Mass Number (P + N). A negativelycharged ion (anion) will have more Electrons than Protons. Cl 1- has one more electron than proton; 18 electrons, 17 protons. That's why its charge is 1-.

Since the number of atoms in a substance is so large , a unit to count them was created. This unit is the number of atoms in 12

larisa86 [58]

The number of atoms in one mole of any substance is measured by Avogadro's number. The value of Avogadro's number is 6.023 x 10 ^23. It is named after scientist Avogadro who proposed this number. 12 grams of carbon-12 represents 1 mole of carbon-12. For this reason, the number of atoms present in 1 mole of any substance is 6.023 x 10 ^23. Therefore, the number of atoms present in 1 mole carbon-12 is 6.023 x 10^23.

(Answer) This unit is the number of atoms in 12 grams of carbon-12 and known as Avogadro's number.

Jack is playing with a Newton's cradle. As he lifts one ball to position A and drops it, it impacts the other balls at position

svetlana [45]

Answer:

Newton's Cradle is a neat way to demonstrate the principle of the CONSERVATION OF MOMENTUM.

What happens here is when the ball on one end of the cradle is swung and it hits the other balls that are motionless, or stationary, the momentum of the swinging ball is transferred to the next ball upon impact.

Momentum is not lost in this action, what happens when it hits the next ball, the momentum is transferred to the next one, and then the next, and the the next, till it reaches the last ball on the other end. Since nothing is next to the last ball, it pushes the ball upwards, which will swing down and repeat the process going the other way.

This also demonstrates the CONSERVATION OF ENERGY. As you will see, the energy continues to move through the other balls, passing it from one ball to the other, which keeps this constantly moving.

Which atom gives up its electrons most easily? THE ANSWER IS “Rb”

Sedbober [7]

Answer:

cesium

In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron
