Answer:

1: The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. 2: The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.

Answer:

1. D

2. C

Explanation:

1. Although now accepted, the theory of continental drift was rejected for many years, with evidence in its favor considered insufficient. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year, was implausibly high.

2.The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.

Answer:

As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

Answer:

Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Answer:

A has 3 electrons in outermost orbit and B has 6 electrons in its outermost orbits. So A can give three electrons to complete its octet and B need 2 electrons to complete its octet. so 2 atoms of A will release 6 electrons and 3 atoms of B will need six electrons to complete their octet So, the formula will be A2 B3.

The chemical formula of the ionic compound formed by these elements when they react together is X₂⁺Y₃⁻.

A compound's makeup is symbolically represented by its chemical formula. It contains charges, ions, etc.

X has 3 electrons in its furthest outer orbit, while Y has 6 electrons there. In order to complete its octet, X can contribute three electrons, but Y requires two electrons.

So, three atoms of Y will require six electrons to complete their octet, while two atoms of X will release six electrons.

Here, the chemical formula is X₂⁺Y₃⁻, as X is donating an electron so it will gain a positive charge, and Y is gaining an electron, so it will gain a negative charge.

Thus, the chemical formula of the ionic compound is X₂⁺Y₃⁻.

ANSWER:

Fe(OH)2

Explanation:

Fe(OH)2

The highest iron content.

A compound is a substance that consists of the atoms or the ions of the two or more different elements that are joined by a chemical bond and can't be separated by any physical means. Like water is a compound of oxygen and hydrogen.

The density of an  object ρ = 24 g/ml

Given

mass of an object = 120 g

volume = 5 ml

Required

The density

Solution

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]

ρ = density  

m = mass  

v = volume  

Input the value :

ρ = 120 g : 5 ml

ρ = 24 g/ml

Answer:

367.1 cm³

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 300 cm³

Initial temperature (T₁) = 40 °C

Final temperature (T₂) = 110 °C

Final volume (V₂) =?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273.15

Initial temperature (T₁) = 40 °C

Initial temperature (T₁) = 40 °C + 273.15

Initial temperature (T₁) = 313.15 K

Final temperature (T₂) = 110 °C

Final temperature (T₂) = 110 °C + 273.15

Final temperature (T₂) = 383.15 K

Finally, we shall determine the final volume (i.e the new volume) of the balloon. This can be obtained by using the Charles' law equation as illustrated below:

Initial volume (V₁) = 300 cm³

Initial temperature (T₁) = 313.15 K

Final temperature (T₂) = 383.15 K

Final volume (V₂) =?

V₁/T₁ = V₂/T₂

300 / 313.15 = V₂ / 383.15

Cross multiply

313.15 × V₂ = 300 × 383.15

313.15 × V₂ = 114945

Divide both side by 313.15

V₂ = 114945 / 313.15

V₂ = 367.1 cm³

Therefore, the new volume of the balloon is 367.1 cm³

Answer:

The added salt will sink to the bottom

Explanation:

A saturated solution is that solution that contains the maximum amount of solute it can dissolve and ,hence, will no longer dissolve any more solute. This question is describing a water solution that is "saturated", this means that water can no longer dissolve any more solute because it has reached the maximum solute limit it can contain.

Hence, adding more solute to a saturated solution like the WATER being described in this question will result in the solute forming a PRECIPITATE at the bottom of the solution. Hence, in this water solution, adding salt to the saturated water solution will result in the added salt sinking to the bottom.
