Answer:

Dissolves

Explanation:

Sediment is a rock material that forms where rocks are broken down into smaller pieces or dissolved in water as rocks erode.

They are products of rock weathering.

Weathering can be defined as the physical disintegration and chemical decomposition of rocks to form sediments and soil.
The first part of the statement describes physical disintegration of rocks where they get broken down into smaller chunks.
The other part simply denotes chemical weathering of rocks which lead to solution of some minerals in the rock.
Both forms are two ways by which rock weathering takes place.

The chemical process in which electrons are gained by an atom or ion is called

spin [16.1K]

Answer:

Explanation:

The process of gaining or losing electrons from a neutral atom or molecule is called ionization. Atoms can be ionized by bombardment with radiation, but the more purely chemical process of ionization is the transfer of electrons between atoms or molecules

For an alloy that consists of 91.0 g copper, 111 g zinc, and 7.51 g lead, what are the concentrations (a) of Cu (in at%), (b) of

viktelen [127]

Answer:

$\% Cu=45.2\%\\\\\% Zn=53.6\%\\\\\% Pb=1.2\%$

Explanation:

Hello!

In this case, given the masses of copper, zinc and lead, it is possible to compute the moles via their atomic masses first:

$n_{Cu}=\frac{91.0gCu}{63.55g/mol}=1.432mol\\\\ n_{Zn}=\frac{111gZn}{65.41g/mol}=1.697mol\\\\n_{Pb}=\frac{7.51gPb}{207.2g/mol}=0.0362mol\\$

Now, we compute the atomic percentages as shown below:

$\% Cu=\frac{1.432}{1.432+1.697+0.0362}*100\% =45.2\%\\\\\% Zn=\frac{1.697}{1.432+1.697+0.0362}*100\%=53.6\%\\\\\% Pb=\frac{0.0362}{1.432+1.697+0.0362}*100\%=1.2\%$

Best regards!

Compound A melts at 801o C and is soluble

Karo-lina-s [1.5K]

Explanation:

Organic compounds are defined as the compounds which contain carbon as their main element. For example, $CH_{3}OH$ is an organic compound.

Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.

As compound A melts at $801^{o}C$ and is soluble in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.

Whereas compound B melts at $24^{o}C$ and is insoluble in water. This means that this compound has covalent bonding and it is also non-polar in nature . Hence, it is more likely to be organic in nature.

Thus, we can conclude that compound B is more likely to be an organic

compound.
