Combine Lead (II) nitrate with Potassium Iodide solution

Chemistry
1 answer:
kati45 [8]3 years ago
7 0

Answer:

When you add lead nitrate to potassium iodide, their particles combine and create two new compounds, a yellow solid called lead iodide (Pbl2) and a white solid called potassium nitrate (KNO3). Yellow clouds indicate that the chemical change has taken place.

Decide which element probably forms a compound with oxygen that has a chemical formula most and least similar to the chemical fo
mafiozo [28]

Answer:

Most similar   -----  Lithium

Least similar   ----  Nitrogen

Explanation:

Cesium is an element on the periodic with the atomic number 133. It lies in group 1 (i.e., the alkali metals) and period 6 on the periodic table. The oxidation state of group 1 metals is +1. Cesium forms an oxide with oxygen as  Cs_2O.

The most similar compound to this chemical compound is Lithium because Lithium happens to be in the same group one metal with Cesium and forms the compound Li_2O with the oxygen

The least similar compound nitrogen due to fact that it is an oxide that is covalent in nature and lies between-group 3 -17  to form an NO_2 with oxygen.

What is the answer to this ?
dybincka [34]
Answer:
D

Explanation:
Because the number of protons is the same as the atomic number, we know what the number of protons has to be 26. The mass number, 55, is the same as the number of protons plus neutrons. Lastly, because there is no charge on this atom, the number of electrons would have to be the same as the number of protons, which is 26.

what is the mole fraction of neon in a mixture that contains 0.628 g of helium, 11.491 g of neon, and 7.613 g of argon?​
VMariaS [17]

Answer:

0.2

Explanation:

Given parameters:

Mass of helium = 0.628g

Mass of neon = 11.491g

Mass of argon = 7.613g

Unknown:

Mole fraction of neon = ?

Solution:

The mole fraction of an element is the number of moles of that element to the total number of moles in the gas mixture.

We need to calculate the number of moles of each element first;

 Number of moles  = \frac{mass}{molar mass}

Molar mass of Helium = 4g/mol

Molar mass of Neon = 20g/mol

Molar mass of Argon = 40g/mol

Number of moles of He = \frac{0.628}{4} = 0.16moles

Number of moles of Ne = \frac{11.491}{20} = 0.58moles

Number of moles of Ar = \frac{7.613}{40} = 0.19moles

Total number of moles = 0.16moles + 0.58moles + 0.19moles = 0.93moles

Mole fraction Neon = \frac{0.19}{0.93}  = 0.2

Which of the following is the correct wedge and dash conformation for the following Newman projection?
kakasveta [241]

We have that  the correct wedge and dash conformation for the following Newman projection is

IV

From the Diagrams above

Two CH_3 groups points on opposite sides in plane

Two Br are on same side  of plane

Two H also on same side of the plane so the plausible  structure is IV

Therefore

The Correct option is IV
