1. Please label the following compounds as
Wittaler [7]

Answer:

A NaCl: ionic (Na is metal and Cl is not metal)

B. AIC13: ionic (Al is metal and Cl is not metal)

C. C2H3N: covalent (C, H and N are nonmetals)

D. C3H60: covalent (C and H are nonmetals)

E. BaCl2: ionic (Ba is metal and Cl is not metal)

F. CaCl2: ionic (Ca is metal and Cl is nonmetal)

Explanation:

In ionic bonds, they are formed when there is a difference in electronegativity, between metals and nonmetals. In the case of covalent bonds, one or more pairs of electrons are shared between nonmetal compounds.

Experimental value of acceleration due to gravity is found to be
KiRa [710]

Answer:

0.33%

Explanation:

From the question given above, the following data were obtained:

Experimental value = 9.842 m/s²

Accepted value = 9.81 m/s²

Percentage error =?

The percentage error in the calculation can be obtained as follow:

Percentage error = |Experimental – Accepted| / Accepted value × 100

Percentage error = |9.842 – 9.81| / 9.81 × 100

Percentage error = 0.032 / 9.81 × 100

Percentage error = 0.33%

Therefore, the error in the calculation is 0.33%

A glass flask has a volume of 500 mL at a temperature of 20° C. The flask contains 492 mL of mercury at an equilibrium temperatu
OverLord2011 [107]

Answer:

101.63° C

Explanation:

Volume expansivity γa = γr -  γ g = 18 × 10⁻⁵ - 2.0 × 10⁻⁵ = 16 × 10⁻⁵ /K

v₂ - v₁ / v₁θ = 16 × 10⁻⁵ /K

(500 - 492 ) mL / (492 × 16 × 10⁻⁵) = θ

θ = 101.63° C

Mm 2mCOO 19. Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH-] is 1 x (3 points) 10-11 mol/L
amm1812

Answer: The hydrogen-ion concentration for the aqueous solution is 10^{-3}mol/L and solution is acidic.

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxyl ion concentration.  

pOH=-\log [OH^-]  

Putting in the values:

pOH=-\log[1\times 10^{-11}]

pOH=11

pH+pOH=14

\pH=14-11=3

pH=-log[H^+]

3=-log[H^+]

[H^+]=10^{-3}M

As pH is less than 7, the solution is acidic.
