How many moles of ZnCl2 will be produced from 28g of Zn assuming CuCl2 is available in excess?
Ok, so we have... Zn + CuCl2 -> ZnCL2 + Cu And we are given that we have 28g of Zn (Zinc). But the question calls for moles of ZnCl2. So, the first step is to convert grams to moles of Zn. We will need to find the AMU (Atomic Mass Units) that a Zn atom's mass. A Zn atom has a mass of 63.546 AMU. Now, we take the given mass and divide it by the mass of the atom to get the moles of reactant we have. 28g/63.546AMU≈ .4406257moles If your teacher/ professor cares about sig figs, then it's .44 because you only have two sig figs from the given from the given mass of Zn (28g). Now, the easy part. What is the ratio of Zn atoms on the reactant side to Zn atoms on the product side? 1:1 And since we have excess CuCl2 Nothing else limits the reaction. So, .44 (or how ever far your teacher wants you to round) moles of Zn reactants in a ideal environment (you will learn later that no reaction is 100% and that there are reactants always left over and how to solve for that) produces .44 moles of ZnCl2.
How many molecules are there in 6.1 moles of H2O?
There are 6.02x1023 atoms in one mole of any substance. This number is a constant known as Avogadro's number. Check it out on wikipedia here...http://en.wikipedia.org/wiki/Avogadro%27s_number. As far as calculating your answer, just multiply and don't lose track of your decimal places.
What are the arrangement of molecules of each state?
Molecules in liquid goes fast and its able to flow around. Molecules in solid aren't able to move around and is stuck together. Lastly, Molecules in gas are able to move around wicked fast and does not bunch together.
Which conditions of p t and n respectively are most ideal for gases?
For gases, the most ideal conditions are low pressure (p), high temperature (T), and low molar volume (V/n). This is described by the ideal gas law equation, PV = nRT, where R is the ideal gas constant. These conditions ensure that gas molecules are far apart from each other and exhibit ideal behavior.
What are facts about gallium?
Perhaps the most interesting thing about gallium is that it has a melting point not far above room temperature. With a melting point of just 86 degrees Fahrenheit (30 Degrees Celsius) the metal will melt in the palm of your hand or on a hot day.

How far can a mole tunnel in one night?
it depends on what kind of soil you put a mole in if it is loose soil then you will find pretty small holes if it is hard soil then you will find some pretty large, deep holes in the ground

How far can a mole travel in your yard in one day?
A mole can typically travel about 100 to 300 feet in a day while foraging for food or expanding its territory. However, this distance can vary depending on factors such as the availability of food, soil conditions, and the presence of predators. Moles are primarily subterranean, so their movements are often limited to their tunnel systems.
Can you breathe in a tunnel?
Yes, you can breathe in a tunnel above ground. If it's far underground, you may have troubles.
How far is it from Royal Oak to the tunnel?

Why was the range between the missions of CA 30 miles?
Because that is how far they were able to travel in a day.
