Ludmilka [50]3 years ago
8 0

Answer:

a negative ion, and an isotope.

Explanation:

The perfect atom consists of an equal balance in all 3. If the neutrons are not even with the protons, it is an isotope since it is like another version of the so called (but not actually) 'perfect' atom. If there is more electrons, the charge is negative, making it an ion.

Elodia [21]

Crust

Core

Explanation:

For any terrestrial planet, the crust would be the coolest layer and the core would be the hottest layer.

Terrestrial planets or the inner planets made up rocky balls. They have layers that are differentiated.

Typically, they are made up of crust, mantle and the core.

The crust is the outermost layer.

The mantle is the middle layer and core is the inner most layer.

These planets are Mercury, Venus, Earth and Mars.

The outermost layer is usually the coldest part.

The innermost layer is the hottest part which is the core

A sample of 25.0 mL of 0.120 M Ca(OH)2(aq) is titrated with 0.150 M HCl(aq). What volume of HCl(aq) is needed to completely neut
stiv31 [10]

Answer:

V_{HCl}=48.0 mL

Explanation:

Hello!

In this case, since the reaction between calcium hydroxide and hydrochloric acid shows a 2:1 mole ratio between them:

2HCl+Ca(OH)_2\rightarrow CaCl_2+2H_2O

We need to use the following mole ratio:

2n_{Ca(OH)_2}=n_{HCl}

That can be written in volumes and concentrations:

2M_{Ca(OH)_2}V_{Ca(OH)_2}=M_{HCl}V_{HCl}

Thus, we solve for the volume of HCl as it is the unknown:

V_{HCl}=\frac{2M_{Ca(OH)_2}V_{Ca(OH)_2}}{M_{HCl}}

Therefore, we plug in to obtain:

V_{HCl}=\frac{2*0.120M*25.0mL}{0.150M} \\\\V_{HCl}=48.0 mL

Best regards!
