0.025 M will be the resulting concentration
Explanation:
To find the resulting concentration we use the following formula:
initial concentration × initial volume = final concentration × final volume
initial concentration = 0.15 M
initial volume = 2 mL
final concentration = ?
final volume = 10 + 2 = 12 mL
0.15 × 2 = final concentration × 12
final concentration = (0.15 × 2) / 12
final concentration = 0.025 M

Answer:
Entropy is a measurement of how much the atoms in a substance are free to spread out, move around, and arrange themselves in random ways
Answer:
H3C - O - O - CH -HCOCH2.
Explanation:
Before chemical reaction can occur, some steps has to be followed in order to give the final product (s), this steps can be shown by drawing the chemical compound and showing how bonds are being broken or formed. Showing this in a stepwise manner is known as reaction mechanism.
From the question above, it is given that the products after heating the reactant gives H3C—0. +.0—CH HCO CH2.
The starting material can be deduce as;
H3C - O - O - CH -HCOCH2.
Heat causes something to divide or melt. Kindly check the attached picture which shows how the deduced starting compound splits to give H3C—0. and .0—CH HCO CH2.
Answer:
10 moles
Explanation:
of moles = given mass /atomic mass = 280 g /28 g = 10 moles of Si atoms in 280g sample.
