Answer:

... the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

Explanation:

This task seeks to examine the knowledge of the kinetic phase and characteristics of matters.

Here we see the chef described that the ingredient's molecules are moving in place – solid.

On the advent of causing the ingredient to change phase by transferring energy into it – the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

How many milliliters of a 0.7% stock solution are required to make 2 l of 0.2% solution? how many ml of solvent will be required
Ierofanga [76]
1. To solve this question, you need to equalize the mass of solute for both solution. The calculation would be:
mass of solute= volume*concentration

mass1=mass2
volume1 * concentration1 = volume2 * concentration2
volume1 * 0.7%= 2L *(1000ml/L) * 0.2%
volume1 = 2000ml * (0.2%/0.7%)
volume1= 571.429 ml

2. Since you already have the volume of stock needed, you just need to subtract it from the total solution volume to count the number of solvents needed.
new solution volume= stock volume + diluting solvent volume
2L * 2000ml/L =  571.429ml + diluting solvent volume
diluting solvent volume= 2000ml- 571.429 ml= 1428.571ml

Describe the journey that a carbon atom inside a fossil fuel will take to become a carbon atom inside a plant
bixtya [17]

When fossil fuels are burnt, CO2 is released into the air and is taken up by plants during photosynthesis to form glucose and subsequently starch.

Fossil fuels contain a large proportion of carbon atoms. When fossil fuels are burnt, these carbon atoms are released as carbon dioxide and escape to the atmosphere as atmospheric CO2 in air.

Recall that plants take up the CO2 in air during the process of photosynthesis. This CO2 becomes combined with water in the presence of sunlight to form glucose.

This glucose is converted to starch and stored in plant tissues. This is how the  carbon atom inside a fossil fuel  becomes a carbon atom inside a plant.

28.5 g of iron shot is added to a graduated cylinder containing 45.50 mL of water. The water level rises to the 49.10 mL mark. F
djyliett [7]

Answer:

Density if iron shot = 7.92 g/ml (2 sig. figs.)

Explanation:

By definition, density is mass per unit volume. That is,

Density (D) = mass(m)/Volume(V)

mass(m) = 28.5g (given)

Volume(V, of iron shot) = 49.10ml - 45.5ml = 3.6ml

Substitutuing into D = m/V = 28.5g/3.6ml = 7.9166667 g/ml (calc.ans)

≅ 7.92 g/ml (2 sig. figs.)

Hope this helps. :-)
