What happens if you overmix muffins?
Answer: When you overmix the muffin batter, it crushes the air bubbles and ruins the fluffy texture.
Explanation: → Follow this tip: To ensure a batch of light, fluffy muffins, mix the dry ingredients with the wet ingredients until just barely combined, and no more dry flour is visible.
What is differentiation
Answer:
The Definition of Differentiation
The derivative is the instantaneous rate of change of a function with respect to one of its variables. This is equivalent to finding the slope of the tangent line to the function at a point

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.

radiation and reflection
Answer:
radiation and reflection
Explanation:
Energy is send from space to earth by radiation and reflection. The most predominant way in which heat is transferred from earth to space is by radiation.
The source of energy for the earth is heat from the sun. This heat can be sent back to space when they are reflected back from the earth and radiated into space.Answer:

Which of the following are reactants in the equation below? Select all that apply.
Zn(s) + CuSO4(aq) = ZnSO4(aq) + Cu(s)
Select all that apply:
A) Zinc
B) Copper
C) Copper (ll) sulfate
D) Zinc sulfate
Answer:
Zinc, copper sulfate
Explanation:
The reactants are the ones on the left side
In the given reaction, it is clearly visible that Zinc and Copper (II) sulfate are the reactants in the equation below. Thus, the correct options are A and C.
What are Reactants?Reactants may be defined as substances or compounds that undergo chemical reactions and have been altered during the course of an incident. Such compounds or substances most of the time are catalyzed by numerous catalysts in order to accomplish the conversion of reactancts substances faster.
The given reaction illustrates an example of a displacement reaction. During this reaction, when zinc is added to copper sulfate solution, zinc displaces copper and forms zinc sulfate solution. It will demonstrate a type of redox reaction.
This happens because on the basis of the reactivity series which determines that zinc is considered to be more reactive than copper.
Therefore, in the given reaction, it is clearly visible that Zinc and Copper (II) sulfate are the reactants in the equation below. Thus, the correct options are A and C.

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.

The concept of continental drift was developed by Alfred Wegener. Which of the following pieces of evidence does NOT support Wegener's hypothesis?
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.
The shapes of the continents fit together like pieces of a jigsaw puzzle
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:

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.
