Answer:
Astrology
Explanation:
One characteristic of science is that it must be reproducible. Other scientists must be able to repeat the original experiments and get the same result. That's what makes scientific claims reliable.
Astrology contends that the positions and motions of stars and planets can affect people and events on Earth. This has been disproved, so astrology is a pseudoscience
.
Biology, chemistry, and physics are sciences.

<u>We can use the </u><u>formula.</u><u> </u>
c1v1 =c2v2
<u>Where c1 is the concentration and v1 is volume of the concentrated </u><u>solution.</u><u> </u>
c2 is the concentration
and v2 is the volume of the diluted solution to be prepared
9.00 M x V1 = 2.75 M x 350 mL
V1 = 106.9 mL
<u>Volume of 106.9 mL from the concentrated solution should be taken and diluted to 350 </u><u>mL</u><u>.</u>

c</span>₀ = 0,050 M.
t = 55 s.
k = 6.96×10⁻³ s⁻¹.
Integrated second
order rate law is: 1/c₁ =
1/c₀<span> + k·t.
</span>1/c₁ = 1/0,050 M + 0,0069 s⁻¹ · 55 s.
1/c₁ = 20,38 1/M.
c₁ = 0,049 M.
In the diagram, an activity which is happening to the temperature at Point B is that: C. The temperature is not rising because the heat is being used to break the connections between the molecules.
<h3>What is matter?</h3>
Matter can be defined as any physical object or body that has both mass and takes up space. This ultimately implies that, the mass of a physical object measures the amount of matter the object contains.
<h3>What is heat?</h3>
In Science, heat is sometimes referred to as thermal energy and it can be defined as a form of energy that is transferred from a physical object (body) to another due to a difference in temperature.
By critically observing the diagram, we can reasonably infer and logically deduce that matter has dynamic states depending on the composition of its atoms and at point B the temperature remained constant (not rising) because the quantity of heat generated is used for breaking any form of connection between the molecules.

Answer : The volume of solution will be, 0.309 L
Explanation : Given,
Mass of = 449.4 g
Molar mass of = 132 g/mole
Concentration = 11 M
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the volume of solution will be, 0.309 L
