The part of the process that requires greater energy is the breaking of bonds between oxygen and hydrogen atoms
What is a chemical reaction?A chemical reaction is said to occur when the chemical bonds in substances break and new bonds are formed. Hence, a chemical reaction involves the breaking and forming of bonds.
We can see that the part of the process that requires greater energy is the breaking of bonds between oxygen and hydrogen atoms because energy in the form of heat had to be supplied for that to happen.

Answer:
This reaction is a chemical reaction because it involves the forming and breaking of bonds. The part of the reaction that is higher in energy is breaking the bond between oxygen and hydrogen atoms. This is because energy is supplied being in the form of heat which requires more energy.
Explanation:
Why does the color absorded by a solution differ from the color of the solution.
Answer:
The size of the particle has a color effect in Rayleigh scatter, but that is unrelated to your question. In the visible spectrum, the main factor determining the color is electronic transitions in the atoms and molecules which make up the substances.
For very simple compounds, it is relatively easy to determine the absorption bands. The bands could possibly change in solution because the electrical environment of the compound’s molecules could change while in solution with water’s polar molecules. However, in many cases, the bands only change slightly so that a purple crystal for example might remain a purple color in aqueous solution.
Some compounds are very sensitive to ionization and to the pH of the aqueous solution, and for these compounds you may see large color shifts as they go into solution.

what is that abbreviated electron configuration for cobalt?
Answer:
[Ar][tex]4s^{2}3d^{7}[/tex]
Explanation:
To write abbreviated electron configurations, begin with the element of interest and work your way down in atomic numbers to the next smallest noble gas.
Write the noble gas symbol in [brackets] and then write the electron configuration as you would normally.

What is the number of moles of kf in a 29-gram sample of the compound.
Given
Weight of pottasium fluoride (KF) = 29 gms
To find
Number of moles of pottasium fluoride = ?
Solution
we know that molar mass of KF = 58.0967 g
Now,
[tex]number \: of \: moles = \ \\ \frac{given \: weight \: of \: subtance}{molar \: mass} [/tex]
Number of moles = 29/58 = 0.5 moles

Which heats up the fastest? treated glass, aluminum, stainless steel, or copper?
Answer:
stainless steel
Explanation:
stainless steel would heat up fast because it is made of metal
101. During the making of steel, iron(II) oxide is reduced to metallic iron by treatment with carbon monoxide gas.
FeO (s) + CO (g) Fe ( s)
Suppose 1.45 kg of Fe reacts. What volume of CO(g) is required, and what volume of CO2(9) is produced, each measured at STP?'
Explanation:
At a certain temperature, iron (II) oxide, FeO, can react with carbon monoxide, CO, to form elemental iron, Fe, and carbon dioxide, CO2. The value of Kp at that temperature is 0.242. What is the pressure of CO2 at equilibrium if a sample of FeO was initially in a container with CO at a pressure of 0.95 atm? The chemical reaction involved in this process is: FeO(s) + CO(g) ⟷ Fe(s) + CO2(
A 350. mL air sample collected at 35°C has a pressure of 550. torr.
What pressure will the air exert if it is allowed to expand to 425 mL at 57°C?
[tex]\tt \dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}[/tex]
T₁ = 35 + 273 =308 K

How many moles of carbon tetrachloride are produced when 4.63 mol of carbon reacts with
excess chlorine? Complete and balance the equation for this chemical reaction first.
Answer:
4.63 moles of CCl4
Explanation:
C + 2Cl2 = CCl4
The balanced equation tells us that we'll obtain 1 mole of CCl4 for every 1 mole of C, assuming we have 2 or more moles of Cl2 (which we do in this problem).
Therefore, if we start with 4.63 moles of C, we'll produce 4.63 moles of CCl4

2. If you are given the mass of a reactant in grams and want to calculate the mass of
a product in grams, what are the three steps of the calculation you must perform?
Answer:
1. Convert given mass of reactant to moles.
2. Convert moles of reactant to moles of product using the coefficients in the balanced equation.
3. Convert moles of product back to grams of product
Explanation:
In order to find out the mass of a given product in grams you would have to convert the grams into moles by multiplying 1 mole over the given mass of the reactant. Then, you would convert the moles of the reactant into moles of the product using mole ratio. And lastly, you would multiply by the mass of the product to calculate the mass back to grams.
