Nails are made up of iron not of phosphorus and barium.
As both phosphorous and barium are relatively weaker than iron ,phosphorus breaks easily and barium is also fairly weak. Iron nails are already also not that strong, but their weight and strength are sufficient.
So the nails are made up of iron.

Answer:
An Omnivore
Explanation: An <u>omnivore</u> is a kind of animal that eats either other animals or plants. Some omnivores will hunt and eat their food, like carnivores, eating herbivores and other omnivores. Some others are scavengers and will eat dead matter. Many will eat eggs from other animals.
Omnivores eat plants, but not all kinds of plants. Unlike herbivores, omnivores can't digest some of the substances in grains or other plants that do not produce fruit. They can eat fruits and vegetables, though. Some of the insect omnivores in this simulation are pollinators, which are very important to the life cycle of some kinds of plants.
Answer:
1
Explanation:
The numbers in front of the formulas (the coefficients) tell you how many moles of a substance are involved in a reaction.
If no coefficient is shown, we assume it is 1.
NOCl has no coefficient, so 1 mol of NOCl is in the balanced equation.
Answer:
25.2 grams HOAc
Explanation:
For solution preparations a simple formula for determining amount of solute needed is ...
from solid stock => grams = Molarity x Volume (Liters) x formula wt of solute
∴ grams HOAc = M·V·f.wt = (0.839M)(0.500L)(60.05g/mol) = 25.2 grams HOAc
Mixing => Transfer gram wt of solute to mixing container and dilute up to but not to exceed total needed volume.
