Answer:

Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost

Is the water found in the watershed clean and safe for drinking?

Dafna11 [192]

I heard that most of the time water found in watersheds aren’t usually clean nor safe for drinking, but i know that there are very few that are somewhat safe for drinking. It’s just not usually common to find clean and healthy watersheds though.

How many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?

Crank

Answer:

The answer is " $\bold{6.26 \times 10^{24} \ molecules \ NH_3}\\\\$ "

Explanation:

1-mole molecules as per Avogadro number $= 6.02 \times 10^{23} \ molecules\\\\$

1-mole $NH_3 \to 6.02 \times 10^{23} \ molecules\\\\$

$10.4 \ moles \ of \ \ NH_3 :$

$\to \frac{ 6.02 \times 10^{23} \ molecules }{ 1 \ mole\ NH_3} \times 10.4 \ mole \ NH_3\\\\ \to 6.02 \times 10^{23} \ molecules \times 10.4\\\\\to 62.608 \times 10^{23} \ molecules \\\\\to 6.26 \times 10^{24} \ molecules \ NH_3\\\\$

if the waste you have contains 100.0 grams of silver nitrate, how many mols of silver nitrate is this? (Use the molar mass of th

hammer [34]

The number of moles is simply calculated by taking the ratio of mass over the molar mass. The molar mass of silver nitrate AgNO3 is 169.87 g/mol. Therefore:

number of moles AgNO3 = 100 g / (169.87 g/mol)

number of moles AgNO3 = 0.59 moles
