According to the kinetic molecular theory, temperature is directly proportional

rjkz [21]

Answer:

According to Kinetic Molecular theory, Temperature is directly proportional to the Average Kinetic energy of a molecules.

Explanation:

If the mass of the particles in a container is constant, then its moving molecules cause the gas gets warmer. On collision of molecules, Kinetic energy of molecules get high, so as a result, temperature gets high.

Fast moving of particles increases the temperature.

Density is an intensive physical property that relates the mass of an object to its volume. Density, which is simply the mass of

xz_007 [3.2K]

Answer: 40731.8 grams of this gasoline would fill a 14.6gal tank

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given : Mass of gasoline = ?

Density of the gasoline = $0.737g/ml$

Volume of the gasoline = 14.6gal = 55267.01 ml (1gal=3785.41ml)

Putting in the values we get:

$0.737g/ml=\frac{mass}{55267.01ml}$

${\text {mass of gasoline}}=40731.8g$

Thus 40731.8 grams of this gasoline would fill a 14.6gal tank

How does skin protect the body from pathogens?

andreev551 [17]

Skin is a barrier that serves as one of the body's first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Yet the skin hosts diverse communities of beneficial bacteria, collectively known as the skin microbiota.

Predict the products of the reaction below. That is, complete the right hand side of the chemical equation. Be sure your equatio

pickupchik [31]

Answer:

2 HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + 2 H₂O

Explanation:

This is a double-displacement reaction. In these reactions, the cation of one molecule swaps with the cation of another.

In this case, the hydrogen cation (H⁺) from HClO₃ swaps with the calcium cation (Ca²⁺) of Ca(OH)₂. When writing the products, keep the charges of the ions in mind. The products must be neutral, so some will need to have more than 1 cation/anion.

The unbalanced equation:

HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + H₂O

Reactants: 3 hydrogen, 1 chlorine, 5 oxygen, 1 calcium

Products: 2 hydrogen, 2 chlorine, 7 oxygen, 1 calcium

The balanced equation:

2 HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + 2 H₂O

Reactants: 4 hydrogen, 2 chlorine, 8 oxygen, 1 calcium

Products: 4 hydrogen, 2 chlorine, 8 oxygen, 1 calcium
