.412 g Mn304/ 1mol * 1 mol Mn304/228.82(MM of Mn3O4 molecule)* 3 mol Mn/1 mol Mn3O4 = .00540 mol Mn *54.94 g/mol = .296 g Mn
To be able to answer this, we need to relate volume with temperature and pressure. To simplify, we assume ideal gas so we use the equation PV=nRT.
PV = nRT
at constant nRT, P1V1 = P2V2
204(11.1) = (0.98)V2
V2 = 2310.61 L
Answer: The answer is D
Explanation:Covalent bonds are formed when atoms share one or more electrons. Ionic bonds are formed when one atom transfers electrons to another atom. how are bond energy and bond strength related? Please give me Brainliest
One way that in advance and biotechnology companies unintended consequence is that harm the environment would be D. Genes implanted into a species of plant can spread to other plants.
1) first, write the balanced equation:
2KOH + H₂SO₄ ---> 2H₂O + K₂SO₄
2) convert grams of sulfuric acid to mole using it's molar mass.
molar mass H₂SO₄= (2 x 1.01) + 32.0 + (4 x 16.0)= 98.0 g/mol
2.70 grams (1 mol/ 98.0 grams)= 0.0276 moles
3) use the mole to mole ratio from the balanced equation to change the moles of sulfuric acid to moles of potassium, hydroxide (KOH).
ration--->2 mol KOH = 1 mol H₂SO₄
0.0276 mol H₂SO4 (2 mol KOH/ 1 mol H₂SO₄)= 0.0551 mol KOH
4) convert moles to grams using the molar mass of KOH
molar mass of KOH= 39.1 + 16.0 + 1.01= 56.1 g/mol
0.0551 mol (56.1 grams/ 1 mol)= 3.09 grams
