A suspension is a heterogeneous mixture of a finely distributed solid in a liquid. The solid is not dissolved in the liquid, as is the case with a mixture of salt and water.

puteri [66]

To identify in what beakers will a reaction occur, we need to know what aqueous solution is in the four beakers. Then, we also need to know what metals are placed inside those beakers. Now, we can analyze which metals might or will react to the solution in the beakers.

The prefix 'kilo-' means a thousand. So a kilo-gram is a thousand grams. 1 kilogram=1,000 grams How many kilograms is 1,008 gram

lesantik [10]

Answer: 1.0 kilograms.

Explanation:

One kilogram is equal to a thousand grams.

Supposing x to be the number of kilograms equal to one thousand and eight grams, we can write it as:

1 kg = 1000 grams

x kg = 1008 grams

To solve for x, we can simply divide 1008 grams by 1000 thousand grams to get the answer.

x = 1008 / 1000

x = 1.008

Rounding this value to the nearest tenth, it will become 1.0 kilograms.

how much sodium chloride must be added to 100 mL of water so that its concentration is 20 parts per million assume that the dens

OlgaM077 [116]

Answer: 2mg

Part per million is unit that equal to mg/kg of water or simply $10^{-6}$ . In this case, you asked how much NaCl needed and know the volume of water(100mL), concentration(20ppm or 20 mg/kg) and water density.
Then, the equation would be

concentration = NaCl weight/ water weight
20 x $10^{-6}$ mg= NaCl weight/ (100ml x 1g/ml)
NaCl weight= 20x $10^{-6}$ mg/kg x 100g
NaCl weight= 2000 x $10^{-6}$ g
NaCl weight= 2x $10^{-3}$ g = 2mg
