Please do not ignore, I don’t know how to find the last part so can you please explain it to me? I’m having trouble with that
Answer:
Neutral
Explanation:
U need to count the number of protons and electrons and see which has more...
Here the atom is neutral cause the electrons and protons are equal and cancell each other out.
I hope im right!!
Answer:
To find the overall charge subtract electrons from protons
So in this example its 0
Explanation:
4 Protons
4 electrons
so basically
+4-4=0

Answer:
In algae or any other photosynthetic organism, there is the internalization of carbon dioxide gas in the reaction with water in the presence of sunlight to produce sugar molecules and oxygen gas in the atmosphere. So, photosynthesis is the process that releases or produces oxygen gas.
In cellular respiration (aerobic) the product of photosynthesis, glucose molecules, and oxygen react to produce the energy and releases carbon dioxide and water as byproducts.
The given question is incomplete, it lacks the diagrams (choices), however, the correct choices are attached as image:
The diagrams accurately represent the use of gases in both cellular respiration and photosynthesis is - diagram d. (check image)
CELLULAR RESPIRATION:
is the process in which living organisms obtain energy (ATP) by breaking down food molecules in their cells. It combines glucose and oxygen to produce carbon dioxide (CO2) and water (H2O) as follows: C6H12O6 + 6O2 = 6CO2 + 6H2OPHOTOSYNTHESIS
is the process in which green plants manufacture their own food using energy from sunlight. It combines carbon dioxide (CO2) and water (H2O) to produce glucose and oxygen (O2) as follows:6CO2 + 6H2O = C6H12O6 + 6O2
Thus, The correct choice of the diagram is - diagram d.

PLEASE MARK AS BRAINLIESTHow acidic buffer resist change in pH on addition of acid and base.
Answer:
Buffers are solutions that resist changes in pH, upon addition of small amounts of acid or base. The can do this because they contain an acidic component, HA, to neutralize OH- ions, and a basic component, A-, to neutralize H+ ions. Since Ka is a constant, the [H+] will depend directly on the ratio of [HA]/[A-].

Scientists are unable to research the organs, tissues, and cells of early organisms as these parts are rarely fossilized. Which is one reason for the lack of these fossilized parts?
Answer:
A. These parts quickly decompose.
Explanation: This is because organs are made of tissues that decompose more quickly than bone. Animals mainly eat the organs and tissues of another, not the bones. This results in quick destruction of these parts that are left behind.
Have a blessed day/night! Please mark brainliest if correct! <3
The reason for the lack of these fossilized parts is that these part quickly decompose. Hence option A is correct.
What is fossilization?Fossilization is defined as the mechanisms that are physical, chemical, and biological that result in the long-term preservation of plant and animal remnants. Fossilization is a negative representation of the creature preserved in the substrate as a fossil. Any preserved remains, impression, or trace of a once-living thing from a previous geological age is referred to as a fossil.
Decomposition is defined as the method through which decomposing organic matter yields more basic organic or inorganic elements . The process of recycling nutrients that have been consumed by an organism to create its body begins with decomposition. It is the process through which the dead tissues disintegrate and change into more basic organic forms.
Thus, the reason for the lack of these fossilized parts is that these part quickly decompose. Hence option A is correct.

A chemical reaction produces 138 mol of HBr gas. What volume will that gas occupy at STP?
3.09E3 L
3.09E4L
22.4L
3.25E2L
The chemical reaction at STP results in a volume of HBr gas that is roughly 3.09E3 L.
An example of a chemical reactionIn a chemical reaction, reactants undergo a chemical reaction and transform into products through a chemical process. For instance, when humans breathe in oxygen, it combines with glucose to create carbon dioxide, water, and energy.
The temperature is 273.15 K and the pressure is 1 atm at STP (standard temperature and pressure).
The ideal gas law can be rearranged to account for V:
V = (nRT) / P
Substituting the values we are aware of:
n = 138 mol
R = 0.0821 L·atm/(mol·K)
T = 273.15 K
P = 1 atm
V = (138 mol * 0.0821 L·atm/(mol·K) * 273.15 K) / 1 atm
V = 3,092.1 L

what is the difference between evaporation and boiling
Answer/Explanation:
Let's define both terms
Boiling: is defined as a process whereby the liquid state is turned into gaseous state at a specific boiling point. And it is a fast process.
Evaporation: is defined as a process whereby a natural process in which the increase in temperature or pressure causes liquid to change into gas.
Difference between boiling and evaporation
In boiling, temperature of the liquid remains constant. While in evaporation, temperature of the liquid reduces
In boiling, temperature is required only at boiling point while in evaporation, temperature occurs at any given temperature.
In boiling, bubbles are formed while in evaporation, bubbles are not formed.
In boiling, a source of energy is required while in evaporation, the surrounding supplies the energy required.
Boiling produces heat and does not lead to liquid cooling, evaporation leads to liquid cooling.
The molecules of the liquid move faster in boiling than in evaporation
