CO2 dissolves in water and reacts with the water molecules. Carbonic acid or H2CO3 is formed as a result of when the two react together.

When mixed, you get carbonated water

What mass of the protein gelatin is needed to make 0.5 L of a 3 g/L gelatin solution? Show your work.

REY [17]

Answer:

m = 1.5 gram

Explanation:

Given that,

Density of protein gelatin, d = 3 g/L

The volume of protein gelatin, V = 0.5 L

We need to find the mass of the protein gelatin. The density of an object is given by :

d = m/V

Where

m is mass

$m=d\times V\\\\m=3\ g/L\times 0.5\ L\\\\m=1.5\ g$

So, the required mass is 1.5 gram.

Which part of the mantle is still solid but flows like a heavy liquid

topjm [15]

The Earth is composed of four different layers. Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top. Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy metals (nickel and iron).

<span>The crust is the layer that you live on, and it is the most widely studied and understood. The mantle is much hotter and has the ability to flow. The Outer and Inner Cores are hotter still with pressures so great that you would be squeezed into a ball smaller than a marble if you were able to go to the center of the Earth!!!!!!</span>

Draw a diagram using H+ signs and OH- symbols of a solution that is acidic. Hint: Use the

Dimas [21]

More positive ions shows acidic whereas more negative ions indicates basic solution.

<h3>Which charge show acidic solution?</h3>

That side which has more positive charges is considered as acidic solution while on the other hand, that region where negative charges are present in large number as compared to positive charges is considered as basic or alkaline solution.

So we can conclude that more positive ions shows acidic whereas more negative ions indicates basic solution.
