The law which this student is thinking of is the law of conservation of mass (LOCOM).

<h3>What is LOCOM?</h3>

LOCOM is an abbreviation for the law of conservation of mass and it states that mass is neither created nor destroyed in any chemical reaction.

This ultimately implies that, the mass of any substance in a balanced chemical equation or chemical reaction would remain the same at the end.

According to the law of conservation of mass (LOCOM), the mass of all the reacting chemical elements of any substance must be equal (remain the same) to the mass of the product formed during a chemical reaction.

What are the magnetic quantum numbers possible for a 6s subshell and for a 4f subshell? Drag the correct numbers into each of th
trapecia [35]

For the 6s subshell, the magnetic quantum number is zero while for the 4f subshell we have -3, -2, -1, 0, 1, 2, 3.

<h3>What is the magnetic quantum number?</h3>

The magnetic quantum number takes on values between 0 to (n - l). It gives the orientations of the sublevels. The four types of quantum numbers are;

  • Principal quantum number
  • Azimuthal quantum number
  • Magnetic quantum number
  • Spin quantum number

For the 6s subshell, the magnetic quantum number is zero while for the 4f subshell we have -3, -2, -1, 0, 1, 2, 3.

Rank the states of matter from the LEAST amount of energy to MOST
nataly862011 [7]

Answer:

The ranking of matter from the LEAST amount of energy to MOST amount of energy is;

B. Solid, Liquid, Gas

Explanation:

The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating

Solid state (Least amount of energy)

In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer

Liquid state (Intermediate amount of energy)

As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state

Upon further heating the particles in the liquid acquire more energy and are  and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form

Gaseous state (Most amount of energy)

From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed

Therefore, the correct option is Solid, Liquid, Gas.

A book club wants to raise $5,000 during a dinner fundraiser. The club members have sold 323 adult dinners at $10. 75 each. The
mina [271]

323 * $10.75 = $3472.25 → money raised from adult dinners

$5000 - $3472.25 = $1527.75 → money needed to reach $5000

$1527.75/$5.50 = 277.77 → 278 child dinners
