Answer:

124.26g

Explanation:

Diameter = 1.80 , length (h) = 4.12 , density = 11.4

Density = mass / volume

Volume = area x height

Area = #d2 ➗ 4

Where #(pi) = 3.142

Area = 3.142 x 1.80 square ➗ 4

Area = 10.2/4 = 2.6

Volume = area x height

Volume = 2.6 x 4.2=10.9

Density = mass / vol

Mass = density x vol

Mass = 11.4 x 10.9

Mass 124.26g

N2O5 decomposes to form NO2 and O2 with first-order kinetics. The initial concentration of N2O5 is 3.0 M and the reaction runs f

kow [346]

Answer : The final concentration of $N_2O_5$ is, 2.9 M

Explanation :

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant = $5.89\times 10^{-3}\text{ min}^{-1}$

t = time passed by the sample = 3.5 min

a = initial concentration of the reactant = 3.0 M

a - x = concentration left after decay process = ?

Now put all the given values in above equation, we get

$3.5=\frac{2.303}{5.89\times 10^{-3}}\log\frac{3.0}{a-x}$

$a-x=2.9M$

Thus, the final concentration of $N_2O_5$ is, 2.9 M

This investigation is a controlled experiment, so you can change only one variable at a time. Which reactant do you think Koby s

WINSTONCH [101]

Answer:

The baking soda

Explanation:

This is the more reactive part of the experiment. The more baking soda there is (compared to the vinegar), the stronger the reaction.

Why is baking soda an ionic bond

Kaylis [27]

Because it is made up of sodium, a metal, and carbon, a nonmetal.

Does the temperature of the solvent (water) affect the rate of dissolving?

gregori [183]

Yes. Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
