How many mL of 0.10 M H₂SO₄, is

25.0 ml
50.0 ml
100 ml
150 ml
200 ml

0.0025 moles H₂SO₄

0.0050 moles H₂SO₄

0.0100 moles H₂SO₄

0.0150 moles H₂SO₄

0.0200 moles H₂SO₄

Explanation:

The question is "How many MOLES..."

Molarity, M, is an unit of concentration in chemistry defined as the ratio between moles of solute and liters of solution. To solve this question we must find the moles of 0.10M H₂SO₄ in the volumes:

25.0mL:

0.025L * (0.10mol / 1L) = 0.0025 moles H₂SO₄

50.0mL:

0.050L * (0.10mol / 1L) = 0.0050 moles H₂SO₄

100.0mL:

0.100L * (0.10mol / 1L) = 0.0100 moles H₂SO₄

150.0mL:

0.150L * (0.10mol / 1L) = 0.0150 moles H₂SO₄

200.0mL:

0.200L * (0.10mol / 1L) = 0.0200 moles H₂SO₄

answer; i do believe the correct answer is (river); /// good luck

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
