Answer:

So... yes :)

Explanation:

Viruses are nonliving agents that depend on the host cell that they are infecting to reproduce. They are bundles of genetic material enclosed in a capsid (some viruses have an additional layer called the viral envelop). Viruses can only thrive and replicate inside the environment of a living cell of other organisms. Viruses adapt to the environment (the cell) they are in by infecting the entire cell. Viruses can infect other nearby cells by infecting its genetic code (either DNA or RNA) and spread. Viruses develop and spread by attaching its protein tail to a receptor site on the host cell wall and injecting its genetic material into the host cell. The virus can then take over the cell and spread to infect other cells in a similar way. This is how viruses replicate. Outside of the host cell, most viruses are inert.

Yes, I do think it’s possible because if viruses spread, (like corona), then it could definitley evolve into something worse than a sickness.

What is the volume of 0.80 grams of O2 gas at STP? (5 points) Group of answer choices 0.59 liters 0.56 liters 0.50 liters 0.47 l

Anarel [89]

Answer:

0.56 liters

Explanation:

First we <u>convert 0.80 grams of O₂ into moles</u>, using its molar mass:

0.80 g ÷ 32 g/mol = 0.025 mol

At STP, 1 mol of any given mass occupies 22.4 L. With that information in mind we <u>calculate the volume that 0.025 moles of O₂ gas would occupy</u>:

0.025 mol * 22.4 L/mol = 0.56 L

Thus the answer is 0.56 liters.

Which of the following is the balanced equation for P + O2 → P2O5? Question 3 options: A) 4P + O2 → 2P2O B) P + 5O2 → 2P2O5 C) 4

Luden [163]

Given equation:

P + O2 → P2O5

In order for the equation to be balanced, the stoichiometry of the atoms of one kind on the reactant side must be equal to that on the product

Reactants Products

P = 1 P = 2

O = 2 O = 5

The balanced equation would be:

4P + 5O2 → 2P2O5

Reactants Products

P = 4 P = 4

O = 10 O = 10

Ans: D)

Pls help me i dont know this

r-ruslan [8.4K]

Answer:

1. 12.6 moles

2. 8.95 moles

3. 2A + 5B → 3C

4. 48 moles

Explanation:

1. 2Fe + 3Cl₂ → 2FeCl₃

We assume the chlorine in excess. Ratio is 2:2

2 moles of Fe, can produce 2 moles of chloride

12.6 moles of Fe will produce 12.6 moles of chloride.

2. 2Fe + 3Cl₂ → 2FeCl₃

For the same reaction, first of all we need to convert the mass to moles:

500 g . 1mol / 55.85 g = 8.95 mol

As ratio is 2:2, the moles we have are the same, that the produced

4. The reaction for the combustion is:

2C₂H₆ (g) + 7O₂ (g) → 4CO₂ (g) + 6H₂O (l)

We assume the oxygen in excess.

Ratio is 2:6, so 2 mol of ethane produce 6 moles of water

Therefore 16 moles of ethane may produce (16 .6) / 2 = 48 moles

20 points please help

exis [7]

The answer should be A, flammability.

The isotopes of the same element would result in the same chemical properties, as the number of protons and electrons are not changed, meanwhile, the physical properties would be slightly different with each other because they have different numbers of electrons.

Out of the 4 options, only option A is a chemical property. Chemical properties are the properties of an element reacting with other substances that creates new substances at the end. While physical properties are the ones that does not produces new substances or any reactions. They are usually observable and measurable.

Therefore, since flammability is a chemical property, the answer is A.
