Answer:

<h2>1.8 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 3 cm³

density = 0.6 g/cm³

We have

mass = 0.6 × 3 = 1.8

We have the final answer as

<h3>1.8 g</h3>

Hope this helps you

Which of the following characteristics describes aerobic organisms.
horsena [70]

Answer: Option (3) is the correct answer.

Explanation:

Aerobic organisms are the organisms which survive and grow in the presence of oxygen.

When oxidation of glucose occurs in the presence of oxygen then it is known as aerobic respiration.

In aerobic respiration, food releases energy to produce ATP which is necessary for cell activity. There is complete breakdown of glucose in aerobic respiration that is why more energy is released. Therefore, aerobic organisms become active.

Thus, we can conclude that characteristics very active, efficient use of energy describes aerobic organisms.

When a substance is in the liquid state, how are the particles of that substance<br> behaving
iVinArrow [24]

Answer:

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.

What is the solubility of La(IO₃)₃ in a solution that contains 0.100 M IO₃⁻ ions? (Ksp of La(IO₃)₃ is 7.5 × 10⁻¹²)
love history [14]

<u>Solution and Explanation:</u>

[La3+] = 0.1 M

<u>At the equilibrium: </u>

La(IO3)3 <---->     La3+     +         3 IO3-  

                    0.1 +s             3s      

\mathrm{Ksp}=[\mathrm{La} 3+][\mathrm{IO} 3-]^{\wedge} 3

7.5 * 10^{\wedge}-12=(0.1+s) *(3 s)^{\wedge} 3

Since Ksp is small, s can be ignored as compared to the 0.1

The above shown expression thus becomes:

7.5 * 10 \wedge-12=(0.1) *(3 s) \wedge 3

7.5 * 10^{\wedge}-12=0.1 * 27(\mathrm{s})^{\wedge} 3

s=1.406 * 10^{\wedge}-4 \mathrm{M}

<u>Answer: 1.4*10^-4 M </u>
