What is the correct order of processes in the accretion of planetesimals?

Chemistry

forsale [732]3 years ago

Answer:

Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.

Explanation:

Planetesimals are the foundation or fundamentals of planet formation. The mode of the formation is called accretion. In this process, dust grains or particles mixes with atoms and molecules to form a massive mass which later coalesce or collide to form planets.

The size of the planet formed is determined by the amount of masses of matter that collide.

How many liters of 4.0 M NaOH solution will react with 1.2 mol H2SO4? (Remember to balance the equation.)
nydimaria [60]

Answer:

The answer is D. 0.60 L

Explanation:

The balanced reaction equation including states of matter is;

H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)

More simple:

H2SO4 + 2NaOH → Na2SO4 + 2H2O

Now, we can see from this reaction equation that the mole ratio of NaOH to H2SO4 is 2:1

Number of moles of H2SO4 reacted = 1.2 moles

Hence;

2 moles of NaOH reacts with 1 mole of H2SO4

x moles of NaOH reacts with 1.2 moles of H2SO4

x = 2 * 1.2/1 = 2.4 moles of NaOH

Recall that;

Number of moles = Concentration * Volume

Volume = number of moles/concentration

Volume of NaOH  is obtained from;

Volume = 2.4 moles/ 4.0 M

Volume =  0.60 L
