6CO2 + 6H20 → C,H120, + 602

Chemistry
1 answer:
tatyana61 [14]2 years ago
7 0

Explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 6O2

How many molecules of CO2 are present?

6 moles

How many atoms of oxygen are present in the reactants?

(6 * 2) + (6 * 1 ) = 12 + 6 = 18

How many atoms of carbon are present in the products?

(6 * 1 ) = 6

How many total atoms are present in C6H12O6?

6 + 12 + 6 = 24 atoms

Is the equation above balanced or unbalanced?

This is a balanced equation since the number of atoms of the elements is the same in the reactant and products.

A hot metal plate at 150°C has been placed in air at room temperature. Which event would most likely take place over the next fe
Fantom [35]

Answer:

A

Explanation:

The molecules in both metal and surrounding air will start moving slower because of the sudden decrease in environment tmeperature. The thermal energy around the metal plate decreases, also decreasing the kinetic energy.

What is the pH of a solution that is 0.40 M NaBrO and 0.50 M HBrO (hypobromous acid) (Ka for HBrO = 2.3 x 10^-9)
Pie

Answer

pH=8.5414

Procedure

The Henderson–Hasselbalch equation relates the pH of a chemical solution of a weak acid to the numerical value of the acid dissociation constant, Kₐ. In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid-base pair used to create the buffer solution.

pH = pKa + log₁₀ ([A⁻] / [HA])

Where

pH = acidity of a buffer solution

pKa = negative logarithm of Ka

Ka =acid disassociation constant

[HA]= concentration of an acid

[A⁻]= concentration of conjugate base

First, calculate the pKa

pKa=-log₁₀(Ka)= 8.6383

Then use the equation to get the pH (in this case the acid is HBrO)

pH=8.6383+\log_{10}(\frac{0.40\text{ M}}{0.50\text{ M}})=8.5414

Compare the three atom diagrams. which one shows the electron with the highest potential energy
lara31 [8.8K]

Answer : The one diagram which shows the electron with the highest potential energy is attached below.

Explanation : One can easily find the highest potential energy of the atom just by looking at the diagram, the electron which is from farthest distance from the atomic nucleus will have the highest potential energy in the electron.

If 50% of a radioactive element remains after 4000 years, what is the half-life?
ANTONII [103]

Hey there!

A half-life means after a certain amount of time, half of that substance will be gone/changed after that time.

If 50%, or half, of the element remains after 4000 years, that means the half life must be 4000 years.

Hope this helps!
