Hydrogen containing all compounds are not acts as acids. Why?

Chemistry
1 answer:
Elodia [21]4 years ago
6 0

Answer:

.

Explanation:

Acid = solution that split to H+ or H3O+ pH <7

The compound that can't split to H+ doesn't act as acid.

A plutonium atom undergoes nuclear fission. Identify the missing element in the nuclear equation.
horrorfan [7]

Answer:

_{92}^{226}U

Explanation:

Let's firstly identify the atomic number (the number of protons) of Pu. This is done by referring to the periodic table and finding Pu. The atomic number of Pu is:

Z=94

In order to identify the type of a nuclear decay, we need to find the N/Z ratio. This is the ratio between the number of neutrons and the atomic number of an isotope. The number of neutrons is found by subtracting the number of protons from the mass number:

N=M-Z

That said, the N/Z ratio equation becomes:

N/Z=\frac{M-Z}{Z}=\frac{M}{Z}-1=\frac{230}{94}-1=1.45

This is a relatively high number thinking about the belt of stability of isotopes. Ideally, stable isotopes with a low Z value have an N/Z ratio of 1. Heavier isotopes with Z > 50 would have a slightly higher N/Z ratio and would be stable around N/Z = 1.25. This means we wish to decrease the N/Z ratio as much as possible.

Among all the decays, alpha-decay is preferred to decrease the N/Z ratio significantly (1.45 is much higher than 1.25). That said, we'll release an alpha particle with some nucleotide X of mass M and atomic number Z:

_{94}^{230}Pu\rightarrow _Z^MX+_2^4\alpha

According to the mass and charge conservation law:

230=M+4\therefore M=230 - 4 = 226

94=Z+2\therefore Z = 94-2 = 92

Identify an element with Z = 92 in the periodic table. This is uranium, U:

_{92}^{226}U

Which image shows an ion?
Juli2301 [7.4K]

Answer:

D

Explanation:

Both images have 4 protons (positive particles) and 4 electrons (negative particles) so in total they don't have a charge. (<em>you don't have to worry about neutrons in this case, because they don't have a charge.)</em>

An ion has a charge so neither image is an ion

What is e cell (in units of volts) for a galvanic cell constructed from barium and manganese electrodes?
gulaghasi [49]

Main Answer: The standard electrode potential of galvanic cell constructed from barium and manganese electrode is 4.097.

Explanation:

When the galvanic cell constructed between Manganese and Barium, the half reactions will be as follows:

Mn2+(aq) + 2e-⟶ Mn(s)                                             E1 = −1.185

Ba2+(aq) + 2e-⟶ Ba(s)                                                 E2 = −2.912

By considering the above two reactions, the standard electrode potential can be calculated.

The galvanic cell standard electrode potential is given by E1 + E2 = 1.185 + 2.912 = 4.097 volts

What is standard electrode potential?

Standard electrode potential is defined as the measure of reducing power of any compound or element. Its units are volts.
