Answer:
Atoms making liquids have less attraction than solids, but more than gases
Explanation:
The attraction between atoms in different molecules in a solid is very strong due to strong intermolecular forces present in a solid. However, such intermolecular forces are weaker in liquids than in solids.
This implies that the solid has higher intermolecular forces of attraction compared to gases and liquids. Based on the negligible degree of intermolecular forces between them, a gas has the weakest intermolecular forces hence the atom has very minimal interaction between them.
Precipitation occurs when the product of the ion concentration exceeds the Ksp.
freezer and refrigerator too cold for most bacteria to grow .oven too hot for bacteria to survive
The density of the gold is 19.3 grams/cc so each cc weighs 19.3grams. Now we can obtain the volume of gold from the given dimensions ie 4.72x8.21x3.98= 154.23 cc. So for the answer, just multiply the volume or 154.23 x 19.3= 2976.6 grams is the answer.
Answer:
There are 3.01x10²³ molecules of sucrose
Explanation:
In order to calculate the number of molecules of any atom or compound, we need to use the Avogadro number which is 6.02x10²³. This number could represent atoms or molecules of any mole of compound or atom.
In other words, 1 mole of a certain atom or compound has 6.02x10²³ molecules or atoms.
we have 0.5 moles of sucrose, all we just need to do is a simple rule of 3:
If 1 mole contains 6.02x10²³ molecules
then 0.5 moles will contain:
n° molecules = 0.5 * 6.02x10²³ / 1
<h2>
n° molecules = 3.01x10²³ molecules of sucrose</h2>
Hope this helps
