Answer:
<h3>The answer is 12 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 8 cm³
density = 1.5 g/cm³
We have
mass = 8 × 1.5
We have the final answer as
<h3>12 g</h3>
Hope this helps you
empirical formula = when the percentage compositions by mass of elements in a compound are divided by their relative atomic masses.
from the obtained amount the smallest amount will divide all.
the answers can then be rounded off if in decimals or they can be multiplied by 2 if they have .5 decimals e.g 2.5 , 7.5 , etc.

The answer to your question is D. send the message underwater because a more dense medium produces a louder and faster sound.
The balanced net equation for
BaCl2 (aq) + H2SO4(aq) → BaSO4(s) + HCl (aq) is
Ba^2+(aq) +SO4^2- → BaSO4 (s)
<u><em>Explanation</em></u>
Ionic equation is a chemical equation in which electrolytes in aqueous solution are written as dissociated ions.
<u>ionic equation is written using the below steps</u>
Step 1: <em>write a balanced molecular equation</em>
BaCl2 (aq) +H2SO4 (aq)→ BaSO4(s) +2HCl (aq)
Step 2: <em>Break all soluble electrolytes in to ions</em>
= Ba^2+ (aq) + 2Cl^-(aq) + 2H^+(aq) + SO4^2-(aq)→ BaSO4(s) + 2H^+(aq) +2Cl^- (aq)
step 3: <em>cancel the spectator ions in both side of equation ( ions which do not take place in the reaction)</em>
<em> </em><em> =</em> 2Cl^- and 2H^+ ions
Step 4: <em>write the final net equation</em>
<em> Ba^2+(aq) + SO4^2-(aq)→ BaSO4(s</em><em>)</em>
