Answer:

\boxed{\text{889 g}}

Explanation:

The formula relating the mass m of a sample and the heat q to vaporize it is

q = mL, where L is the latent heat of vaporization.

\begin{array}{rcl}2000 \times 10^{3} \text{ J} & = & m \times \dfrac{2.25 \times 10^{6} \text{ J}}{\text{1 kg}}\\\\m & = & \dfrac{2000 \times \times 10^{3}\text{ kg}}{2.25 \times 10^{6}}\\ & = & \text{0.889 kg}\\\\ & = & \text{889 g}\\\end{array}\\\text{The mass of water is $\boxed{\textbf{889 g}}$}

Predict the number of each atom needed to form a molecule of potassium Sulfide.
vladimir2022 [97]

Answer:

2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.

Explanation:

  • The potassium sulfide has the chemical formula <em>K₂S.</em>

∴ Every 1.0 molecule of K₂S composed of 2.0 atom of K and 1.0 atoms of S.

<u><em>So, 2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.</em></u>

Assuming equal concentrations and complete dissociation, rank these aqueous solutions by their freezing points. K2SO4 NH4I CoCl3
katrin [286]
The substance that releases the greatest amount of ions will have the greatest attractive forces within its solution, resulting in a reduced freezing point.
K₂SO₄ yields 3 ions
NH₄I yields 2 ions
CoCl₃ yields 4 ions

Freezing points:
CoCl₃ < K₂SO₄ < NH₄I

How do particles in matter change when a substance becomes hotter, cool down, or changes state?
Nana76 [90]

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

hope this helps!!!!!!
