Draw the structure of an alkane or cycloalkane that has more than three but fewer than ten carbon atoms, and only primary hydrogens. (There are several possible structures. It is enough to draw any one of them, but you may draw two or more if you want to.)
How many moles of each ion are in each solution? (a) 2 mol of potassium perchlorate dissolved in water K+ mol ClO4- mol (b) 255 g of magnesium acetate dissolved in water Mg2+ mol C2H3O2- mol
A neon is made of glass tubing whose inside diameter is 2.5 cm and whose length is 5.5 m. If the sign contains neon at a pressure of 1.73 torr at 31 degrees celcius
At 25 degrees Celsius the rate constant for the first-order decomposition of a pesticide solution is 6.40 x 10^-3 min^-1 If the starting concentrate of pesticide is 0.0314M what concentration will remain after one hour at 25degreesC
Glycine has the structure NH2CH2COOH. it can lose a proton from the carboxyl group and form chelate rings bonded through both the N and one of the O atoms. Draw structures for all possible isomers of tris(glycinato)cobalt(III).
The electrons in the neutral carbon atom are redistributed so that there are three lone electrons in the three 2p orbitals and one lone electron in the 2s orbital.
What is the wavelength of a baseball having mass 100.0 g traveling at a speed of 160 km/hr? What is the wavelength of an electron traveling at the same speed
The concentration of Mg2+ in seawater is 0.052 M. What is the pH when 95% of the magnesium ions will be precipitated as the hydroxide salt. (Ksp, Mg(OH)2 is 8.9 x 10-12).
Calculate the resulting pH if 400 mL of 0.50M HCl is mixed with 300 mL of 0.080 M NaOH.
Electrophilic Substitution, Which compound is more reactive toward electrophilic substitution (e.g., nitration)? Explain you reasoning.
Determine the molecular geometry of each of the following molecules
A 30.00 mL solution of potassium nitrate (KNO3) was diluted to 125.0 mL, and 25.00 mL of this solution were then diluted to 150.0 mL. The concentration of the final solution is 0.00307 M. Calculate the concentration of the original solution.
