Volume = to 4 by 3 π r square. pls follow the formula and try to do it
Answer:
1 cm/s
Explanation:
From the question given above,
the student is trying to convert 0.010 m/s to a number in cm/s.
Thus, we can convert 0.010 m/s to cm/s as illustrated below:
Recall:
1 m/s = 100 cm/s
Therefore,
0.010 m/s = 0.010 m/s × 100 cm/s ÷ 1 m/s
0.010 m/s = 1 cm/s
Therefore, 0.010 m/s is equivalent to 1 cm/s
Answer:
99.56 g.
Explanation:
- The balanced reaction is:
<em>3Ca(NO₃)₂ + 2Na₃PO₄ → 6NaNO₃ + Ca₃(PO₄)₂.</em>
It is clear that 3.0 moles of Ca(NO₃)₂ react with 2.0 moles of Na₃PO₄ to produce 6.0 moles of NaNO₃ and 1.0 mole of Ca₃(PO₄)₂.
- We need to calculate the no. of moles of 96.1 g of Ca(NO₃)₂:
n = mass/molar mass = (96.1 g)/(164.088 g/mol) = 0.5857 mol.
<u><em>Using cross multiplication:</em></u>
3.0 moles of Ca(NO₃)₂ produce → 6.0 moles of NaNO₃.
0.5857 moles of Ca(NO₃)₂ produce → ??? moles of NaNO₃.
∴ The no. of moles of NaNO₃ = (6.0 mol)(0.5857 mol)/(3.0 moles) = 1.171 mol.
<em>∴ The no. of grams of NaNO₃ = (no. of moles of NaNO₃)(molar mass)</em> = (1.171 mol)(84.99 g/mol) = <em>99.56 g.</em>
Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue reacts with water to produce pink colored complex.
In this complex, ion forms an octahedral complex with six ligands.
As is a weak field ligand therefore ion remains in low spin state.
Hence electronic configuration of ion in this octahedral geometry is with total three unpaired electrons.
A. is the answer, because the more an experiment is repeated, it will become apparent if it yields the same results thus confirming or debunking the hypothesis.
