Group of answer choices
Fossils of the same organisms are found on different continents.
Similar glacial sediments are found in different parts of the world.

Climates at different latitudes are similar to one another.
Answer:
Climates at different latitudes are similar to one another.
Explanation:
The choice that is not a proof of Wegener's concept of concept of continental drift is that climates at different latitudes ae similar to one another.
Wegener did not use climatic evidence to proof continental drift. He did use fossils found on different continents such as the mesosaurus to propose the theory of continental drift. Wegener also used evidence of glacial sediments to justify his claims. He also fitted the earth into a giant puzzle.Answer:
Climates at different latitudes are similar to one another.

Why does the salt reappear when the water evaporates??
Answer:
Salt particles move about the water. Each particle is surrounded by water molecules.The water particles (molecules) keep the salt particles from rearranging themselves back into a salt crystal. Salt particles are carried throughout the solution surrounded by water particles.
As the water evaporates less and less water molecules are present to keep the salt particles apart. The salt therefore recrystalises and can be collected.

Answer:
2.14 x 10²⁴ formula units
Explanation:
Given parameters:
Number of moles of NaCl = 3.55moles
Unknown:
Formula units of NaCl = ?
Solution:
A mole of substance contains the avogadro's number of particles. The number of particles could be protons, atoms, neutrons, formula units etc.
1 mole of substance = 6.02 x 10²³ formula units
3.55 mole of NaCl = 3.55 x 6.02 x 10²³

a graduated cylinder begins with a volume of 30.0ml. If a rock is added to the graduated cylinder, the water level rises to 75ml. The mass of the rock is 55.0g. What is the density of the rock?
Initial volume of graduated cylinder = 30.0 mL
Final volume of graduated cylinder after adding rock = 75.0 mL
Volume of the rock = Final volume of graduated cylinder after adding rock - Initial volume of graduated cylinder
= (75.0 - 30.0) mL
= 45.0 mL
Mass of the rock = 55.0 g
[tex] \rm Density = \dfrac{Mass}{Volume} \\ \\ \rm = \dfrac{55}{45} \\ \\ \rm = 1.23 \: g/mL[/tex]

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?
Given:
The overall average speed = 25 cm/s.
The overall average speed increased by 10%.
To find:
The new overall average speed.
Solution:
We have,
Overall average speed = 25 cm/s.
The overall average speed increased by 10%. So, the new average speed is
New overall average speed = Initial average speed + 10% of initial overall average speed
[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]
[tex]\text{New overall average speed}=25+2.5[/tex]
[tex]\text{New overall average speed}=27.5[/tex]
Therefore, the new overall average speed is 27.5 cm/s.

What is a limiting reagent? A.) The reactant that is used up first in a reaction B.) The reactant that is used the least reactive in a reaction C.) the reactant with the smallest coefficient in the equation D.) the reactant with the largest coefficient in the equation
Answer: A.) The reactant that is used up first in a reaction
The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. A limiting reagent is the reactant that is used up first in a reaction. Therefore, option A is correct.
What is a limiting reagent?A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
The terms limiting reagent and limiting agent may also be used to describe the limiting reactant.
Thus, option A is correct.

What ion will be formed by the selenium atom shown below when it has a stable set of valence electrons?
Selenium atom
A. Se6+
B. Se2+
C. Se6-
D. Se2-
Answer:
Explanation:
D. Se2−
Selenium is in Group 16 of the periodic table, and it typically has 6 valence electrons. To achieve a stable set of valence electrons, it will either try to gain two more electrons to form Se²⁻or lose six electrons to form Se⁶⁺. Therefore, the correct option is option D.
An ion is an atom or a molecule that has gained or lost one or more electrons, resulting in an unequal number of protons and electrons. When an atom gains electrons, it becomes negatively charged and is called an anion. Conversely, when an atom loses electrons, it becomes positively charged and is called a cation.
Ions play a crucial role in chemical reactions and the formation of chemical compounds, as they are attracted to one another based on their opposite charges. This process helps stabilize the electron configuration and achieve a more stable, lower-energy state.
Thus, the ideal selection is option D.

A large balloon contains 233 L of neon at 22.0C and 760. Torr. If the balloon ascends to an altitude where the temperature is - 52.0C and the pressure is 511 torr, what is the volume in the balloon at the higher altitude?
Answer: The volume in the balloon at the higher altitude is 260 L
Explanation:
The combined gas equation is,
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 760 torr
[tex]P_2[/tex] = final pressure of gas = 511 torr
[tex]V_1[/tex] = initial volume of gas = 233 L
[tex]V_2[/tex] = final volume of gas = ?
[tex]T_1[/tex] = initial temperature of gas = [tex]22.0^0C=(22.0+273)K=295K[/tex]
[tex]T_2[/tex] = final temperature of gas = [tex]-52.0^0C=(-52.0+273)K=221K[/tex]
Now put all the given values in the above equation, we get:
[tex]\frac{760\times 233}{295}=\frac{511\times V_2}{221}[/tex]
[tex]V_2=260L[/tex]
The volume in the balloon at the higher altitude is 260 L
