HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)

Chemistry
1 answer:
Mariulka [41]3 years ago
5 0

Answer:

Amount of H_{2}O produced will be half of its original value.

Explanation:

Balanced reaction: HCl+NaOH\rightarrow NaCl+H_{2}O

According to balanced equation, 1 mol of HCl reacts with 1 mol of NaOH to produce 1 mol of H_{2}O

If amount of reactants (NaOH and HCl) are halved then we can write-

0.5 mol of HCl reacts with 0.5 mol of NaOH to produce 0.5 mol of H_{2}O.

So, it is evident that amount of H_{2}O to be produced will be half if amount of reactants are halved.

Aleonysh [2.5K]

Answer:

CuSO4 cell will have the greatest amount of deposit among all three. The deposit will occur at the cathode

Explanation:

The valence of the elements in this case is as follows -

Cu - 2e-

Sn - 4e-

Cr - 3e-

CuSO4 cell will have the greatest amount of deposit among all three

The atoms of copper metal will deposit at the cathode. At the cathode, the least number of moles of electrons needed .

Hence, more amount of copper  can be extracted out by the electrolyte

The number of micrograms of contaminant each person will receive is 5,742.64 ug.

<h3>Number of micrograms of contaminant  per person</h3>

The number of micrograms of contaminant each person will receive is calculated as follows;

Amount of contaminant (mg) = (1.01 x 10⁻⁴ mg/mL) x 2.28 x 10⁴ L

Amount of contaminant (mg) = 2.3028 mg.L/mL

Amount of contaminant (mg) = (2.3028 mg.L/mL) x (1000 mL/L) = 2,302.8 mg

Amount of contaminant (ug) = 2,302.8 mg x 1000 ug/mg = 2,302,800 ug

<h3>Amount of contaminant per person (ug/person) </h3>

=  (2,302,800 ug) / (401 persons)

= 5,742.64 ug per person

List down the observations made by Rutherford during the gold foil experiment.
Travka [436]

Answer:

1) The volume occupied by an atom is composed of mainly empty space

2) Atoms have a very small, relatively dense, central nucleus that is positively charged

3) The region around the nucleus of an atom are orbited by negatively charged electrons in a the same fashion planets orbit around the Sun.

Explanation:

The selection of gold for the gold foil experiment was due to its ability to be rolled into extremely thin sheets such that it was expected for alpha particle to perforate or pass through the foil.
