Since molarity (M) is measured in mols÷L, you will need to convert the units first.
Then, convert 160g of ammonium nitrate into mols using the molar mass 80.043g/mol.
160g ÷ 80.043g/mol = 2.0 mols.
Finally divide the mols by liters.
2.0mols ÷ 2.5L = .80M
Answer:
D. Metals
Out of the 118 elements only about 30% are not made of metal. This can be tested easily if you have household items that have metal in them or some that do not. Additionally you will need a magnet to tell if there is really metal.
Answer:
The C4+ ion has the smallest ionic radius
Explanation:
In the periodic table, the size of an atom increases on going downwards in a group.
On the other hand, in a period, size decreases on going from left to right
The size of cation is smaller than its parent atom.
Lithium-ion (Li+) is the most left so it has the biggest radius.
More to the right ( this means a smaller ionic radius) , we have Berylium-ion (Be2+).
More to the right, so smaller than Be2+, we have B3+
The ion the most to the right, we have C4+
The C4+ ion has the smallest ionic radius
Li+ > Be2+ > Be3+ > C4+
Acetic acid is soluble in water, while olive oil is insoluble in water. like water, acetic acid is polar. olive oil is nonpolar, so it is not soluble in water.
Hope this helps you :)
-Warning2
1) d
2) b because the independent variable is the thing you change/control in an experiment
3) c because the dependent variable is the thing being measured in an experiment
4)hmm it might be d, as c and a are both correct as different sized feeders would make it an unfair test and different types of food would as well
5) c
6) a
7) b obviously because if he activated them at different times then the ones activated last would have an advantage
