$speed = \frac{distance}{time}$

$distance = speed \times time$

$distance = 80 \times 5 = 400m$

Time=5s
Speed=80m/s

$\\ \sf\longmapsto Distance=Speed(Time)$

$\\ \sf\longmapsto Distance=5(80)$

$\\ \sf\longmapsto Distance=400m$

If 0.089 grams of KI is dissolved in 500g of H2O, what is the concentration of the resulting solution in parts per million?

frez [133]

Answer:

The concentration of the resulting solution in parts per million is 177.97

Explanation:

Parts per million (ppm), is a unit of measure for concentration that refers to the number of units of the substance per million units of the set.

The concentration in parts per million expressed in mass / mass is calculated by dividing the mass of the solute (ms) by the mass of the solution (md, sum of the mass of the solute and the mass of the solvent), both expressed in the same unit and multiplied by 10⁶ (1 million).

$ppm=\frac{ms}{md} *10^{6}$

So, being:

ms: 0.089 grams of KI

md: 0.089 grams of KI + 500 grams of H₂O= 500.089 grams

Replacing:

$ppm=\frac{0.089 grams}{500.089 grams}*10^{6}$

ppm= 177.97

The concentration of the resulting solution in parts per million is 177.97

If a graduated cylinder has 28ml of water in it and you add an object which causes the water level to rise to 47ml, what is the

grin007 [14]

Answer:

The object placed in the water has a volume of 19 cm³

Explanation:

Step 1: Data given

volume of the cylinder before adding the object = 28 mL = 28 cm³

After adding an object with volume X the volume rises to 47 mL = 47 cm³

Step 2: Calculate the volume of the object

Volume of the object = Final volume - initial volume

Volume of the object = 47 cm³ (or 47 mL) - 28 cm³ ( or 28 mL) = 19 cm³ (or 19 mL)

The object placed in the water has a volume of 19 cm³

When sulfuric acid and potassium hydroxide neutralize each other to make water and potassium sulfate, how is water formed?

statuscvo [17]

It's formed by the hydrogen ion of the acid and the hydroxide of the base.

$H_{2} SO_{4} + 2KOH --\ \textgreater \ K_{2} SO_{4} + 2H_{2}O$
Sulfuric Acid + potassium superoxide --> Potassium Sulfate + Heavy Water

Hope this Helps :)
