Answer:

You need to add 300mL of a pure acid to produce a 60% acid solution.

Explanation:

Pure acid is a 100% acid. If you suppose X is the volume addition of the pure acid it is possible to write:

100%X + 600×40% = (600+X)60% (M₁V₁=M₂V₂)

100X + 24000 = 36000 + 60x

40X = 12000

X = 300

That means you need to add 300mL of a pure acid to produce a 60% acid solution.

I hope it helps!

The mass of an erlenmeyer flask is 85.135 g. after 10.00 ml of water is added to the flask, the mass of the flask and the water

BARSIC [14]

Subtracting the mass of (flask+water) from the empty flask gives:
95.023 g - 85.135 g = 9.888 grams of water
Dividing this by the given volume of 10.00 mL water gives:
9.888 grams of water / 10.00 mL of water = 0.9888 g/mL of water
Therefore, based on this sample, the density of water is 0.9888 g/mL, which is close to the usually accepted approximation of 1 g/mL.

Which type of heat transfer does the situation below model? At a sports event, the spectators do the 'wave'. Starting at one end

Zanzabum

Answer:

radiation

Explanation:

Based on the scenario being described in the question it can be said that the type of heat transfer that is being modeled is radiation. Like demonstrated in the picture attached below, radiation involved the transfer of heat through rays, waves, or particles as opposed to fluids or gases. Which is what is happening in this scenario, since the individuals are building up heat by moving and that heat is being passed on to the individuals around them through waves.
