Answer 1

Answer:

A wave is phenomenon that transfers energy from one point to another through a disturbance without affecting the matter.

Explanation:

A wave is phenomenon that transfers energy from one point to another through a disturbance without affecting the matter.

There are two main types of waves Longitudinal waves travels parallel to their source. For example, sound waves. Through a series of rarefactions and compressions, longitudinal waves are propagated. Transverse waves travel perpendicular to their source.

Answer:

B. A few positive particles bounced back because they were pushed away from the positive center.

Explanation:

The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.

This is the central theme of Rutherford's experiment on a thin gold foil.

In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.

choose the letter that best describes the behavior of a substance during a phase change:

/A/ neither absorbs or releases energy

/B/ always absorbs energy

/C/ always releases energy

/D/ either absorbs or releases energy

Answers

Answer:

/D/ either absorbs or releases energy

Explanation:

During a phase change energy is either absorbed or released.

A phase change is a reversible process which occurs when a substance changes is its state from one form to another.

Phase changes are used to delineate physical changes.

A phase diagram provides a graphic representation of the change. The diagram can be 2 dimensional or 3 dimensional.

25 cm of liquid 'A' and 20 cm of liquid
'B' are mixed at 25°C and the volume of
solution was measured to be 44.8 cm3
then correct reaction is
(A) A Hmix = 0, solution shows
ideal

Answers

Answer:

The correct option is;

(B) [tex]\Delta H_{mix} < 0[/tex], solution shows negative deviation

Explanation:

The given parameters are;

The available volume of liquid A = 25 cm³

The available volume of liquid B = 20 cm³

The volume of the solution (mixture) = 44.8 cm³

Therefore, we have;

[tex]\Delta _{mix} V < 0[/tex]

Which is one of the prerequisite for the formation of negative deviation

When a non-ideal solution shows negative deviation according to Raoult's Law, we have;

[tex]\Delta _{mix} H < 0[/tex], we have more heat released due to new molecular interactions.

Which of the following is the correct model of C7H16?
A.
B.
C.
D.

Answers

Answer:

D

Explanation:

Option D gives the correct model of C7H16. From the option, one will discover that the model has 7 carbons in the backbone. If you count the attached hydrogen, you will discover that the hydrogen is 16 in total.

This model or skeletal structure of this element represents heptane. Heptane or n-heptane is known to be a straight-chain compound and an alkane. It's chemical formula can also be written as: H₃C(CH₂)₅CH₃ or C₇H₁₆.
