What is a solution in chemistry

1 answer:

4 0

Solutions are a type of mixture.

A solution is a homogeneous mixture of particles so small that they cannot be seen and cannot be filtered out.

Definition: Homogeneous mixture looks the same.

I grabbed these from my science notes, hope this helps.

How many protons, electrons, and neutrons does 1 H+ isotope contain

nlexa [21]

<h3>Answer:</h3>

H+ contains 1 proton, 0 neutrons, 0 electrons.

<h3>Explanation:</h3>

An atom is the smallest particle of an element that can take part in a chemical reaction.
Atoms are made of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
A hydrogen atom contains 1 proton and 0 neutrons in the nucleus and 1 electron in the energy levels.
A hydrogen atom loses an electron to form an ion with 1 proton, 0 neutron and 0 electron.

How do protons electrons and neutrons differ in charge and location in the atom?

dlinn [17]

Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.

A hot air balloon can have a volume of 2950 cubic meters (2.95 ✕ 106 liters) and operate at temperatures up to 250°F (121°C). As

Answer:

2.64 × 10⁶ g

Explanation:

We can find the mass of air using the ideal gas equation.

$P.V=n.R.T=\frac{m}{M} .R.T$

where,

P is the pressure (P = 1.00 atm)

V is the volume (V = 2.95 × 10⁶ L)

n is the number of moles

R is the ideal gas constant (0.08206atm.L/mol.K)

T is the absolute temperature (121°C + 273 = 394 K)

m is the mass

M is the molar mass (28.09 g/mol)

$m=\frac{P.V.M}{R.T} =\frac{1.00atm \times 2.95 \times 10^{6} L \times 28.97g/mol}{(0.08206atm.L/mol.K) \times 394 K } =2.64 \times 10^{6} g$
