Answer:
<h2>It'll float</h2><h2>Less than 1g/cm3 it'll float in water </h2>
Answer:
Your question is not interpreted very well, but as regards what is observed, SO2 is not the formula for sulfur oxide, the formula for sulfur oxide is SO since the valence used in sulfur would be +2 and oxygen -2 therefore the sum of these valences would be equal to zero, therefore it would be the correct thing considering the true equation as SO
Explanation:
There are also sulfur dioxide, or sulfur trioxide, which is usually used in the formation of tertiary salts such as copper sulfate.
sulfur trioxide and sulfur dioxide are synonymous with sulfate or sulphite
Answer:
There is 17,114825 g of powdered drink mix needed
Explanation:
Step 1 : Calculate moles
As given, the concentration of the drink is 0.5 M, this means 0.5 mol / L
Since the volume is 100mL, we have to convert the concentration,
⇒0.5 / 1 = x /0.1 ⇒ 0.5* 0.1 = x = 0.05 M
This means there is 0.05 mol per 100mL
e
Step 2 : calculate mass of the powdered drink
here we use the formula n (mole) = m(mass) / M (Molar mass)
⇒ since powdered drink mix is usually made of sucrose (C12H22O11) and has a molar mass of 342.2965 g/mol.
0.05 mol = mass / 342.2965 g/mol
To find the mass, we isolate it ⇒0.05 mol * 342.2965 g/mol = 17,114825g
There is 17,114825 g of powdered drink mix needed
Answer:
2
Explanation:
The 1 & 2 are both signifigant becuase they are presented in scientific notation.
