Has anyone ever done this atom escape room thing

Chemistry
1 answer:
SVEN [57.7K]3 years ago
4 0

Answer:

1.  negative

2.  positive

3.  neutral

Explanation:

Ok so it looks like they are asking for the charge (positive, negative, or neutral) of each thing

So for 1, it would be negative, because it's pointing to an electron.  Electrons always have a negative charge.

So for 2, it would be positive, because it's pointing to a proton.  Protons always have a positive charge

So for 3, it would be neutral, because it's pointing to a neutron.  Neutrons always have a neutral charge.

What would you do to change a saturated solid/liquid solution to an unsaturated solution
Semenov [28]

Explanation:

Saturated solid/liquid solution is changed to an unsaturated solution by the dilution process.

When the saturated solution is diluted by addition large quantity of solvent it changed to an unsaturated solution.

Saturated solid/liquid solution can also be changed to an unsaturated solution by increasing the temperature or heating the solution.

A saturated solution is a solution where further solute will not dissolve in the solvent.

An unsaturated solution is a solution in which has the ability to dissolve more solute.

Balance the following reaction: AL2O3 + HCI ⇒ ALCI3 + H2O
Anastaziya [24]
To balance the following chemical equation, make a tally or a count of each of the atoms on both sides of the reaction, and make sure that those atoms are equal on both the reactant and product side.

AL2O3 + HCl => ALCl3 + H2O

Left side. Right side
AL = 2. AL = 1
O = 3 Cl = 3
H = 1. H = 2
Cl = 1. O = 1

First balance the metal atoms, aluminum, then hydrogen and then oxygen.

Balanced equation :
AL2O3 + 6HCl => 2ALCl3 + 3H2O.

Left side. Right side
AL = 2 AL = 2
O = 3 Cl = 6
H = 6 H = 6
Cl = 6 O = 3.

What is the concentration of a solution with a volume of 660L that contains 33.4g of AlCO3?
lana [24]

Answer:

The concentration of the solution is 5.8168 × 10^{-4} mol.dm^{-3}

Explanation:

Here, we want to calculate the concentration of the solution.

The unit of this is mol/dm^3

So the first thing to do here is to calculate the number of moles of the solute present, which is the number of moles of AlCO3

The number of moles = mass/molar mass

molar mass of AlCO3 = 27 + 12 + 3(16)  = 27 + 12 + 48 = 87g/mol

Number of moles = 33.4/87 = 0.384 moles

This 0.384 moles is present in 660 L

x moles will be present in 1 dm^3

Recall 1 dm^3 = 1L

x * 660 = 0.384 * 1

x = 0.384/660 = 0.00058168 = 5.8168 * 10^-4 mol/dm^3
