Juliet is using a paper towel to clean up a juice spill. The liquid sticks to the paper towel because of _____.adhesion
cohesion
specific heat
a neutral pH

Answers

Answer 1
Answer: When Juliet uses a paper towel to clean up a juice spill the liquid sticks to paper towels because of adhesion and absorption. Paper towels are made of cellulose fibres, which are made of sugar. Water molecules stick to the sugar.
Answer 2
Answer:

Answer: Option (a) is the correct answer.

Explanation:

When molecules of different substance stick together due to force of attraction then this property is known as adhesion.

In the given situation juice sticks to the paper towel due to adhesion as it gets absorbed by the towel.

Thus, we can conclude that out of the given options, the liquid sticks to the paper towel because of adhesion.

8. why the partial negative charge occurs in a molecule of water?

Answers

Answer:

Explanation:

The partial negative charge in a water molecule occurs because of differences in electronegativity between the atoms involved. A water molecule (H2O) consists of two hydrogen atoms and one oxygen atom. Oxygen is significantly more electronegative than hydrogen, which means it has a stronger attraction for electrons.

In a covalent bond between hydrogen and oxygen, such as in a water molecule, electrons are shared between the two atoms. However, because oxygen is more electronegative, it pulls the shared electrons closer to itself, creating an uneven distribution of electron density. This results in the oxygen atom having a partial negative charge (δ-) and the hydrogen atoms having partial positive charges (δ+).

The electronegativity difference between hydrogen and oxygen causes the electrons in the covalent bonds to spend more time around the oxygen atom, making it partially negatively charged. This partial negative charge on the oxygen atom and the partial positive charges on the hydrogen atoms give water its polar nature. This polarity plays a crucial role in various chemical and physical properties of water, such as its ability to form hydrogen bonds, its high surface tension, and its unique solvent properties.

In Ernest Rutherford's gold foil experiments, some alpha particles were deflected from their original paths, but most passed through the foil with no deflection. Which statement about gold atoms is supported by these experimental observations?Gold atoms consist mostly of empty space.

Gold atoms are similar to alpha particles.

Alpha particles and gold nuclei have opposite charges.

Alpha particles are less dense than gold atoms.

Answers

According to ErnestRutherford's gold foil tests, the true statement is that space makes up the majority of gold atoms. The correct option is A.

According to Rutherford's studies, the majority of the alphaparticles encountered free space inside the atom since they mostly went through the gold foil with little to no deflection.

This finding helped scientists comprehend that atoms have a small, compact nucleus at their center and are primarily made up of empty space elsewhere in the atom.

The nuclearmodel of the atom was created as a result of the deflection of several alpha particles, which showed that they came into contact with the positively charged atom's nucleus.

Thus, the correct option is A.

Which rigid cylinder contains the same number of gas molecules at STP as a 2.0-liter rigid cylinder containing H2(g) at STP?(1) 1.0-L cylinder of O2(g)
(2) 2.0-L cylinder of CH4(g)
(3) 1.5-L cylinder of NH3(g)
(4) 4.0-L cylinder of He(g)

Answers

When we say STP that means the system is at its standard temperature and pressure. Both systems is having the same condition hence temperature and pressure is constant. We then set the amount of gas in both cases to be equal. Hence from the ideal gas law, 
PV=nRT we can say that with everything constant, volume must also be constant. 

The answer is (2) 2 L of methane gas. 

2.0-L cylinder of CH₄ (g) contains the same number of gas molecules at STP as a 2.0-liter rigid cylinder containing H₂(g) at STP.

What is ideal gas equation?

It is a hypothetical approximation of the behavior of many gases under many condition, and expressed as PV = nRT.

As in the question it is given that rigid cylinder have the same temperature and pressure i.e. have a standard temperature and pressure. According to the Avogadro's Law, under the same temperature and pressure if equal amount of gas is taken then no. of moles of gases are same.

Ideal gas equation PV = nRT justifies the above statement.

So, from the given 2.0-L cylinder of CH₄ (g) contains the same number of gas molecules at STP.

Hence, option (2) is correct i.e. 2.0-L cylinder of CH₄ (g) contains the same number of gas molecules.
