7 0

1. Rust, or Fe2O3, is a Chemical Compound.

2. Carbon is a Chemical Element found as C on the periodic table.

3. Apple Juice is a Heterogeneous Mixture, as it is uniform throughout. If it wasn't uniform, there would be yucky lumps in your apple juice :)

If I helped you out, I would greatly appreciate if you went through my other answers I gave you and gave them the brainliest answer :)

A flask contains a gas mixture of hydrogen, nitrogen and methane. The total pressure of the mix is 3.0 atm. The partial pressure

ollegr [7]

Answer:

$P_{N_2}=1.0atm$

Explanation:

Hello,

Considering the Dalton's law which states that the total pressure of a gaseous system is defined by the summation of the the partial pressures of the present gases:

$P_T=\Sigma P_i$

For the given system:

$P_T=P_{H_2}+P_{N_2}+P_{CH_4}$

Solving for the partial pressure of nitrogen we obtain:

$P_{N_2}=3.0atm-0.5atm-1.5atm=1.0atm$

Best regards.

A molecule of composition is replicated in a solution containing unlabeled (not radioactive) GTP, CTP, and TTP plus adenine nucl

Lapatulllka [165]

Answer:

Please find the complete question in the attached file.

Explanation:

It would only be radioactive if the DNA molecule that employed the poly-T rand as templates. Its other molecule of the daughter would not have been radioactive as it did not need dATP for its replication. While each strand of the second molecule includes t, simultaneous reproduction dATP from both daughter molecules is needed so that each of those is radioactive.

Iron that is tin-plated does not rust. Why not?

Gemiola [76]

Rust is iron oxide, the corrosion product of iron when exposed to the oxygen in the air. Tin is not iron, so you cannot produce iron oxide from the corrosion of tin. Because the layer of tin on the surface of the steel prevents atmospheric oxygen and moisture from contacting the steel.

The monatomic ions of Groups 1A(1) and 7A(17) are all singly charged. In what major way do they differ? Why?

insens350 [35]

Answer: Group 1 ions are known as cations and Group 17 ions are known as anions.

Explanation:

Ions are formed when an atom looses or gains electrons.

If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine is a Group 17 element which gains 1 electron to form $F^-$ ions.

If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium is a Group 1 element which looses 1 electron to form $Na^+$ ions.

Hence, group 1 ions are known as cations and Group 17 ions are known as anions.
