What's up ? ! ? You should know most of these.

RbOH is a base because its PH is greater than 7.

Sulfur trioxide is SO₃ .

Mixtures B, C, and D can be separated by distillation.
Pebbles and sand can't.

If some salt is dissolved in a beaker of water, then
the salt is the solute and the water is the solvent.

The equation is not balanced because the number of atoms
of each element on the left is not equal to the number of atoms
of that element on the right.
In fact, the total number of all atoms on the left (8) is not even
equal to the total number of all atoms on the right (10).

How do i find the number of leptons in an atom??

Serjik [45]

Answer:

In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions.[1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.

A rock is dropped from a bridge to the water below. It takes 2.40 s for the rock to hit the water (a) find the speed in m/s of t

Artyom0805 [142]

Answer: I think Its the Height is 11.76 Meters (38.582677 Feet) between the bridge and the ground

Explanation: Supposing that where not counting air resistance in the equation, the equation $D = ut+\frac{1}{2} at^{2}$ states that 1/2 multiplied by earths gravitational acceleration multiplied by the amount of time to reach the bottom: 2.4 seconds equals 11.76 meters of height between the bridge and the ground.
