Answer:
D) forms hydronium ions in water
Explanation:
Texture and conductivity are physical properties which makes answer A and B wrong. Answer C does not refer to a chemical reaction.
Answer:
C. He shot tiny alpha particles through a piece of gold foil.
Explanation:
In the year 1911, Ernest Rutherford performed the gold foil experiment which gave a deeper perspective to the structure of an atom.
He simply collided a thin gold foil with an alpha particle which he generated from a radioactive source. He discovered that most of the alpha particles passed through the thin gold foil but a few were deflected back. His discovery led to the proposition of the nuclear model of the atom.
<u>Answer:</u> The complete molecular, ionic, and net ionic equations are given below. The spectator ions are sodium and nitrate ions.
<u>Explanation:</u>
The ionic equation is defined as the equation in which all the substances that are strong electrolytes present in an aqueous state and are represented in the form of ions.
The net ionic equation is defined as the equations in which spectator ions are not included.
Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.
The balanced molecular equation for the reaction of lead (II) nitrate and sodium sulfide follows:

The ionic equation follows:

As sodium and nitrate ions are present on both sides of the reaction. Thus, they are considered spectator ions.
The net ionic equation follows:

Answer:
1. 10.37114 psi
2. 71.5178 KPa
3. 71517.8 Pa
4. 536.56 mmHg.
5. 21.12352 inHg
Explanation:
From the question given,
Pressure = 0.706 atm
The pressure in other units of measurement is obtained as follow:
1. Pressure in Psi
1 atm = 14.69 psi
Therefore, 0.706 atm = 0.706 x 14.69 = 10.37 psi
2. Pressure in KPa
1 atm = 101.3 kPa
Therefore, 0.706 atm = 0.706 x 101.3 = 71.5178 KPa
3. Pressure in Pa
1 atm = 1.013x10^5 Pa
Therefore, 0.706 atm = 0.706 x 1.013x10^5 = 71517.8 Pa
4. Pressure in mmHg
1 atm = 760mmHg
Therefore, 0.706 atm = 0.706 x 760 = 536.56 mmHg
5. Pressure in inHg
1 atm = 29.92 inHg
Therefore, 0.706 atm = 0.706 x 29.92 = 21.12352 inHg
