The difference is that in a nuclear reactor it uses normal pressures and temperatures that are relative to earth using fission , where as in the sun, fusion happens and with that comes extremely high temperatures and bone squishing pressures.
Substance 3 Is most likely to be a Metal for Its malleability and conductive properties.
Answer:
pH= 3.82
Explanation:
Sodium ethanoate or sodium acetate (CH3COONa) ionises completely.
Ethanoic acid or acetic acid (CH3COOH), ionises partially because it is a weak acid.
Answer:
1.06 M
Explanation:
Lets answer this question using the definition for molarity of a solution, M.
M = mol of solute/ Volume of solution in L
We are adding more moles of NaOH to a solution which is already 2.40, so the final number of moles are
25 g x 1 mol / 40 g/mol = 0.625 mol
mol NaOH in 1.5 L of 2.40 M NaOH:
1.5 L x 2.40 mol/L = 3.6 mol
Total # mol = 0.625 mol + 3.6 mol = 4.23 mol
The final volume is 4.00 L so the new molarity is:
M = 4.23 mol / 4 L = 1.06 M
Answer:
630 mL
Explanation:
0.281 M = 0.281 mol/L
0.177 mol /0.281 mol/L =0.630 L
0.630 L=630 mL
