Answer:
Yes, Pb3(PO4)2.
Explanation:
Hello there!
In this case, according to the given balanced chemical reaction, it is possible to use the attached solubility series, it is possible to see that NaNO3 is soluble for the Na^+ and NO3^- ions intercept but insoluble for the Pb^3+ and PO4^2- when intercepting these two. In such a way, we infer that such reaction forms a precipitate of Pb3(PO4)2, lead (II) phosphate.
Regards!
Answer:
The answer is granitic or felsic rocks
Explanation:
Felsic is a term used in geology applied to silicate minerals, magmas and rocks, rich in light elements such as silicon, oxygen, aluminum, sodium and potassium (describs igneous rocks that are relatively rich in elements that form feldspar and quartz). This term is a combination of the words "feldspar" and "silica". Felsic minerals are generally light in color and have a specific gravity of less than 3. The most common felsic minerals are quartz, muscovite, alkaline feldspars (eg orthoclase) and feldspars from the plagioclase series. The most common felsic rock is granite. At the opposite end of the rock spectrum are mafic (rich in iron) and ultramafic (rich in magnesium) rocks and minerals.
Answer:
They have the same number of electron energy levels.
They transition from a metal to noble gas.
Explanation:
Periods in the periodic table of elements refer to elements in the same row. All the elements in a certain row of the periodic table;
have the same number of electron energy levels.
transition from a metal to noble gas.
Answer:
The answer to your question is: letter A
Explanation:
a. Ribonucleotides have a hydroxyl group on the 2 carbons of their sugar sub-unit. This is the main difference between Ribonucleotides and deoxyribonucleotides, the first have hydroxyl group in carbon number two, while the second have a hydrogen.
b. Ribonucleotides contain a phosphate group.
c. Ribonucleotides have a hydrogen atom on the 1 carbon of their sugar sub-unit.
d. Ribonucleotides contain a sugar with five carbon atoms.
Based on the bond length, the molecular weight of the unknown metal X is 23.
<h3>What are ionic compounds?</h3>
Ionic compounds are compounds which are formed between oppositely charged ions.
When hydrogen combines with the group 1 metals, they form ionic compounds.
The group one metals that combine with hydrogen to firm ionic bonds include:
- Lithium to give Lithium hydride with equilibrium bond length of 0.239Å.
- Sodium to give sodium hydride with equilibrium bond length of 1.896Å.
- Potassium to give potassium hydride with equilibrium bond length of 2.321Å
The molecular weight of lithium is 7 g
The molecularweight of sodium is 23
The molecular weight of Potassium is 39.
Therefore, based on the equilibrium bond length, the molecular weight of the unknown metal X is 23.
