In plant cells, how are chloroplasts and mitochondria related?
Answer:
Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.
How did mitochondria
become part of the cell?
Answer: The mitochondria, as bacteria, only wanted to rob the host cells of their energy and then leave them to die. But the bacteria soon realized the benefit of working together with simple cells. The simple cells provide them with antioxidants to protect them from free radicals and toxic reactive oxygen species that the mitochondria generate as a byproduct of energy production.

Convert 300K to degrees Celsius.
Explain the role light plays on the rate
of photosynthesis.
Answer:
The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
What is radiation exactly
radiation is energy that comes from a source. (travels through the speed of light)
Will there ever be grams of a limiting reactant remaining after a reaction has stopped? Why or why not?
Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

what volume is needed to make a 2.45 M solution of KCl using 0.50 mol of KCl
The molarity of a substance is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
[tex]Molarity = \frac{mole}{volume }[/tex]
From the question given above, the following data were obtained:
Molarity of KCl = 2.45 M
Mole of KCl = 0.5 mole
Volume =?The volume of KCl needed can be obtained as follow:
[tex]Molarity = \frac{mole}{volume }\\\\2.45 = \frac{0.5}{Volume }[/tex]
Cross multiply
2.45 × Volume = 0.5
Divide both side by 2.45
[tex]Volume = \frac{0.5}{2.45}\\[/tex]
Volume = 0.20 LTherefore, 0.20 L is needed to make the solution.

A. How many bonds are between hydrogen and chlorine?
Explanation:
yes, chlorine and hydrogen form a polar covalent bond. Chlorine has a quantity of 7 electrons and hydrogen has only 1 electron, for this reason an unequal bond will form, that is, it will be uneven in distribution.

its temperature
its color
its ability to decompose into hydrogen and oxygen
its state
Answer:
At 4°C what is not able to decompose into hydrogen and oxygen chemical changes cannot be reverted, in this case it can. It will not change color, because water is always clear, and won't at this state turn into ice. though it can be reverted.

89. What is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C?
0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.
What is an ideal gas equation?The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
According to Ideal Gas Equation,
PV = nRT
Therefore, P ∝ T
P₁T₂ = P₂T₁
Given :
P₁ = ?
P₂ = 1.11 atm
T₁ = 30.0 C
T₂ = 15 C
Solving :
P₁ x 30 = 1.11 x 15
P₂ = 0.555 atm
Hence, 0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.

Which mass is made up of 6.02x10^23 atoms? none of these 23 g sodium 42 g krypton 24 g carbon 78 g potassium
Answer:
23 g sodium
Explanation:
In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).
According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23
Using the formula; mole = mass/molar mass
- Sodium = 23g/23g/mol = 1mol
- Krypton = 42g/84g/mol = 0.5mol
- Carbon = 24g/12g/mol = 2mol
- Pottasium = 78g/39g/mol = 2mol
Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

how many kg of solvent would contain 130 grams of ZnBr2 if the solution was 0.950 grams
Answer:
0.00731 kg
Explanation:
Given that solution is a product of solute and solvent.
Hence, solution = solute * solvent
In this case, the solution is given as 0.950 grams = 0.00095 kilograms
solute is given as 130 grams = 0.13 kilograms
Hence to get the amount of solvent in kilograms, we have
Solution ÷ Solute => 0.00095 ÷ 0.13
= 0.0073076923
=> 0.00731 kilograms

if you had to explain to a friend how to balance a chemical equation, what
would you say to them?
Answer:
make sure that the number of atoms on the left side of the equation equals the number of atoms on the right.
Explanation:
A chemical reaction can be balanced by multiplying each side with suitable integers such that the number of each element in the reaction must be equal number on both side.
What is a balanced chemical equation?According to the law of conservation of mass for a chemical reaction, the total mass in the reactant side is equal to the total mass in the product side. Thus, a balanced chemical equation represents the perfect stoichiometry for each reactants and products.
The number of each elements in both side have to be equal in number. If they are unequal on both side, we can balance the reaction by multiplying with suitable integers.
Lets have one example. Consider the given reaction.
[tex]\rm CH_{4} + O_{2} \rightarrow H_{2}O + CO_{2}[/tex]
Here, 4 H are in left side and only 2 in right side. Similarly number of oxygen also not balanced.
The balanced equation requires a coefficient of 2 for water and 2 for oxygen in reactant thus, it can be written as:
[tex]\rm CH_{4} + 2O_{2} \rightarrow 2H_{2}O + CO_{2}[/tex]

This question is about iron three of the raw material added to a blast furnace used to extract iron from henatite are coke hematite and limestone name one other raw material added to the blast furnace
Answer: The fourth material that is added to the blast furnace is HOT AIR which provides OXYGEN for used for combustion of carbon (Coke).
Explanation:
Iron is the second most abundant metal found in the earth's crust after aluminium. It is not found in the free metallic state but are extracted from rocks which are rich in iron that contains other materials. These are known are iron ores and the most common iron ores are haematite ( Fe2O3).
Iron can be extracted from its ore with the used of blast furnace. The materials used for extraction of iron includes:
--> Coke
--> haematite( iron ore)
--> limestone and
--> Hot air.
The iron ore is first roasted in air so that iron(III)oxide is produced. The iron(III)oxide is then mixed with coke and limestone and heated to a very high temperature. Hot air is introduced into it from the bottom of the furnace. The coke is oxidizes the the oxygen in the hot air blast to liberate carbondioxide.
