Answer:
it would be a cation ... i believe
Explanation:
To become a cation, a positively charged ion, an atom would have to lose at least two electrons
Answer:
The positively charged particle will go towards the negatively charged particle because opposites attract.
Explanation:
Answer: 0.34 mol
Justification:
1) Hepta means 7, so heptahyrate means 7 parts of water. On mole of magnesium sulfate heptadydrate has seven moles of water.
2) The formula of magnesium sulfate heptahydrate is:
Mg SO4 . 7 H2O
3) Calcualte the number of moles of the compound by dividing the mass in grams by the molar mass of formula.
molar mass:
Mg: 24.3 g/mol
S: 32.1 g/mol
O4: 4 * 16.0 g/mol = 64.0 g/mol
H2: 2 * 1.0 g/mol = 2.0 g/mol
O: 16 g/mol
Molar mass = 24.3 g/mol + 32.1 g/mol + 64.0 g/mol + 2.0 g/mol + 16.0 g/mol = 138.4 g/mol
number of moles = mass in grams / molar mass = 6.81 g / 138.4 g/mol = 0.049 mol
4) As stated, there are 7 moles of H2O per each mol of heptahydrate compoind, so the number of moles of water is 7 * 0.049 mol = 0.343 mol
Answer: 0.34 mol
potassium group number is 1 and the period is 4
You may find in the attached picture the structure for compound (A) and (B).
Explanation:
The compound (A) and (B), which are haloalkanes, will undergo base-promoted E2 elimination and it will form the alkene (C) with the double bond in the second position. Zaitev's rule, which is an empirical rule, tell us that the halogen will leave with the hydrogen from the neighbor carbon which have the lowest amount of hydrogen, in the picture this specific hydrogen have a blue color.
Further compound (C) it will form compound (A), as a major product, by addition of hydrobromic acid. The Markovnikov's rule, which is also empirical, tell us that the halogen from the acid will add the carbon, involved in the double bond, that have the lowest amount of hydrogen.
Compound (C) will participate to a hydrogenation reaction to form 2,6-dimethylheptane.
