The answer is in a spoon Bc it’s metal
deff fn [24]3 years ago

Answer:

Well if you're talking about heat then the ice cream in the spoon would melt faster because there is only a little bit of COLD ice cream, but if you're talking about cold then it would be the gallon because it has the most amount of ice cream to keep it cold for a longer time which will prevent it to melt.

1.) You have 4.2 moles of magnesium (Mg). How many atoms of magnesium do you have?
NNADVOKAT [17]
1) N = 4,2 moles
M = 24,31 u
m = N x M
= 4.2 x 24.31 = 102.102 kg


2) m = 54.9 grams = 0.0549 kilograms
M (Na) = 22.99 u
N (moles) = m / M
N = 0.0549 / 22.99 = 2.4 x 10^-3 moles

Is chemical a example of natural forces
Nastasia [14]
The only types of natural forces are gravitation, electromagnetism, the weak interaction, and the strong interaction. So no, chemical is not an example of a natural force.
I hope this helps.

Using the 5M NaCI and 10% glucose stock solutions you generated, how would you prepare 100 ml of a solution that is both 150mM N
fredd [130]

Answer:

Take 3 mL of the 5 M NaCl solution, 10 mL of the 10% glucose solution, and add water for a final volume of 100 mL.

Explanation:

  • In order to calculate the required volume of the 5 M NaCl solution, we calculated the moles contained in a 100 mL solution that has a concentration of 150 mM:

0.1 L * 0.150 M = 0.015 moles of NaCl

With those moles we can calculated the required volume, using the concentration of the stock solution:

0.015 mol / 5 M = 0.003 L = 3 mL.

  • To make a solution that has a 1 % concentration of glucose, from a 10 % glucose solution, is the same as to make it ten times less concentrated. Thus, with a final volume of 100 mL, you would need to take 10 mL of the 10% glucose solution, because 100mL * 10/100 = 10.

So in order to prepare the solution, you would need to take 3 mL of the 5 M NaCl solution, 10 mL of the 10% glucose solution, and add water for a final volume of 100 mL.
