Based on science 4) 1) 0.25M
2) 0.66M
3) 1.5M
4) 4.0M ––> Therefore, this is the most concentrated
5) 30g NaOH(1 mol NaOH / 40gNaOH) = 0.75 mol NaOH / 0.500L = 1.5M NaOH (3)
6) 1) 1.0 mol / L(1 L) = 1 mol H2SO4
2) 1 mol / L (2 L) = 2 mol H2SO4
3) 0.50 mol / L ( 1.0L) = 0.50 mol H2SO4 ––>
7) 0.200 mol / L (1 L)(74.6g / mol) = 14.92g (2)
8) 0.25 mol / 0.250 L = 1 mol / L = 1M (1)
This is the answer : 1m
Answer:
no it would be 2.5 mill your welcome
Explanation:
You input potential (stored<span>) </span>energy<span> into the </span>rubber band<span> system when you </span>stretched<span> the</span>rubber band<span> back. Because it is an </span>elastic<span> system, this kind of potential </span>energy<span> is specifically </span>called elastic<span> potential </span>energy<span>. ... When the </span>rubber band<span> is released, the potential </span>energy<span> is quickly converted to kinetic (motion) </span>energy<span>.</span>
Answer:
Manganese (Mn)
Explanation:
We know it's manganese because we are told it is an electrically neutral atom. This means it has the same number of protons and electrons. If it has 25 electrons, it has 25 protons. Protons tell us the atomic number of the atom, which also tells us the name of the element. Manganese is element 25 on the periodic table.
