Answer:

Explanation:

"The thermal energy moving from her coffee to the tongue" represent the heat.

Here coffee is at high temperature while tongue is at low temperature, when Ixchelt tongue make contact with coffee then thermal energy of coffee is absorbed by tongue and tongue gets burned.

As heat always from high Potential to low that is why heat is absorbed by tongue.

Which of the following represents energy in its most disordered form? Group of answer choices Chemical-bond energy Electromagnet

gavmur [86]

Answer: Heat Energy

Explanation:

Heat is energy in its most disordered form. heat energy is the random jostling of molecules and is therefore not organized. As cells perform the chemical reactions that generate order within, some energy is inevitably lost in the form of heat. Because the cell is not an isolated system, the heat energy produced by the cell is quickly dispersed into the cell's surroundings where it increases the intensity of the thermal motions of nearby molecules. This increases the entropy of the cell's environment and keeps the cell from violating the second law of thermodynamics.

One molecule of bromine (Br2) and two molecules of potassium chloride (KCI) combine in a reaction. How many atoms are in the pro

Liula [17]

In the reaction between 1 molecule of bromine and 2 molecules of potassium chloride, there are six atoms in the products.

Let's consider the balanced equation for the reaction between 1 molecule of bromine and 2 molecules of potassium chloride. This is a single replacement reaction.

Br₂ + 2 KCl ⇒ 2 KBr + Cl₂

We obtain as products, 2 molecules of potassium bromide and 1 molecule of chlorine.

1 molecule of KBr has 2 atoms, so 2 molecules contribute with 4 atoms.
1 molecule of Cl₂ has 2 atoms.
The 4 atoms from KBr and the 2 atoms from Cl₂ make a total of 6 atoms.

In the reaction between 1 molecule of bromine and 2 molecules of potassium chloride, there are six atoms in the products.

deff fn [24]

Answer:

the red sphere has a charge of 9.899 10⁻⁶ C and

the green sphere 0.101 10⁻⁶ C

Explanation:

For this exercise we will use coulomb's law

F = k q₁ q₂ / r²

where they indicate the value of the force F = 2.5 N, the distance between them r = 0.06 m

they also indicate the value of the total load

q₁ + q₂ = 10 10⁻⁶ C

we substitute the values

2.5 = 9 10⁹ q₁ q₂ / 0.06²

2.5 0.06 2/9 10⁹ = q₁ q₂

1 10⁻¹² = q₁ q₂

10 10⁻⁶= q₁ + q₂

we have two equations with two i unknowns, so the system can be solved.

q₁ = 1 10⁻¹² / q₂

we substitute in the other equation

10 10⁻⁶ = 10⁻¹² / q₂ + q₂

let's solve the equation

10 10⁻⁶ q₂ = 10⁻¹² + q₂²

q₂² - 10⁻⁵ q₂ + 10⁻¹² = 0

q₂ = [10⁻⁵ ± √(10⁻¹⁰ - 4 10⁻¹²)] / 2

q₂ = [10⁻⁵ + - 0.9798 10⁻⁵] / 2 = 10⁻⁵ (1 + - 0.9798) / 2

q₂ = 0.9899 10⁻⁵ C

q₂ = 0.0101 10⁻⁵ C

let's find the charge of the other sphere

q₂ = 0.9899 10⁻⁵ C

q₁ = 10⁻⁵ - q₂

q₁ = 10⁻⁵ - 0.9899 10⁻⁵

q₁ = 0.0101 10⁻⁵ C

therefore the red sphere has a charge of 9.899 10⁻⁶ C and

the green sphere 0.101 10⁻⁶ C
