metals react with ? what

Answer:

B) -1.00 M/min

Explanation:

Based on the reaction:

2 SO2(g) + O2(g) → 2SO3(g)

2 moles of SO2 are consumed per mole of O2 producing 2 moles SO3

In the problem, the sulfur dioxide has a rate of change of -2.00M/min. As the moles of oxygen that reacted are half the moles of SO2, its rate of change is halved, that is:

Answer:

3, non polar causes the molecule to not have a twin molecule. polar just means it has a correspondent

Answer:

[tex]Q=113,000J[/tex]

Explanation:

Hello there!

In this case, since the vaporization process is carried out in order to turn a liquid into a gas due to the addition of heat, we can use the following heat equation involving the heat of vaporization of water or any other substance:

[tex]Q=m*\Delta _{vap}H[/tex]

Thus, since this heat of vaporization for water is 2259.36 J/g, we plug in this amount to obtain the total energy for this process.

[tex]Q=50*2259.36 J/g\\\\Q=113,000J[/tex]

Which is positive due to the necessity of heat.

Answer:

pH is not been modified. No changes.

Explanation:

Our buffer is made of acetic acid, a weak one and the salt from its conjugate base, sodium acetate.

NaC₂H₃O₂ → Na⁺   +  C₂H₃O₂⁻

The acetate anion can make hydrolisis in water to produce acetic acid again.

C₂H₃O₂⁻  + H₂O  ⇄  C₂H₃O₂H + OH⁻     Kb

KCl is neutral salt. When we dissociate it:

KCl → K⁺  +  Cl⁻

Both ions come from a strong base and a strong acid. They won't make hydrolisis in water because they are conjugate weak acid and base

K⁺ + H₂O ← KOH + H⁺

Cl⁻ + H₂O ← HCl + OH⁻

These reactions can't be possible.

That's why it doesn't occur anything in our buffer, this salt does not give OH⁻ or H⁺ to medium to modify pH

Explanation:

Answer:

-It occurs naturally in the Sun.

-It released a large amount of energy.

-It involves the joining of two atomic nuclei.

It occurs naturally in the Sun.

It released a large amount of energy.

It involves the joining of two atomic nuclei.

Hence, options B, C and D are correct.

Nuclear fusion involves the fusion of 2 smaller nuclei into bigger nuclei.

Nuclear fission and nuclear fusion are nuclear reactions that produce energy in the form of heat. Fission is the process of the division of heavy, unstable nuclei into two nuclei, and in fusion two nuclei combine, resulting in the release of energy.

It occurs naturally in the Sun -The proton-proton fusion is the source of energy from the Sun. The energy from the sun occurs inside the core of the Sun.

It released a large amount of energy - Fission and fusion are two physical processes and produce large amounts of energy from atoms.

It involves the joining of two atomic nuclei - Nuclear fusion happens in the Sun and other stars when two atomic nuclei make one larger one.

Hence, options B, C and D are correct.

Answer:

2682.9J is the heat absorbed by the wood

Explanation:

To find the heat absorbed for a material we must use the equation:

Q = S*m*ΔT

Where Q is heat absorbed in Joules

S is specific heat of the material = 1.76J/g°C for wood

m is the mass of the material = 41.2g

ΔT is change in temperature = 65.1°C - 28.1°C = 37.0°C

Replacing:

Q = 1.76J/g°C*41.2g*37.0°C

Q = 2682.9J is the heat absorbed by the wood

Answer:

The role of consumers in an ecosystem is to obtain energy by feeding on other organisms and sometimes transfer energy to other consumers. Changes that affect consumers can impact other organisms within the ecosystem.

Explanation:

Hope this helped Mark BRAINLIEST!!!!

Consumers are organisms that obtain energy by eating other organisms. Consumers may consume either producers or other consumers. Consumers include animals.

A food chain is a network of links in a food web that begins with producer organisms and ends with an apex predator, detritivore, or decomposer species.

A food chain also demonstrates how organisms are related to one another through the food they consume. Each trophic level is represented by a different level of a food chain.

Producers can produce their own food and energy, but consumers are not the same. Consumers are living things that must hunt, gather, and eat their food.

Thus, Consumers must eat in order to gain energy, or they will perish. Omnivores, carnivores, herbivores, and decomposers are the four types of consumers.

Answer:

Percent yield = 55.9%

Explanation:

To solve this question we must find the moles of the reactants in order to find limting reactant. Using the chemical equation and limiting reactant we can find the moles of DDT assuming a 100% of yield (Theoretical Yield). As percent yield is:

Percent Yield = Actual yield (464g) / Theoretical Yield * 100

We can find percent yield as follows:

Moles chlorobenzene- Molar mass: 112.56g/mol-

827g * (1mol / 112.56g) = 7.35 moles

Moles chloral -Molar mass: 147.3877g/mol-

345g * (1mol / 147.3877g) = 2.34 moles

For a complete reaction of 2.34 moles of chloral are required:

2.34moles CHOCl3 * (2mol C6H5Cl / 1mol CHOCl3) = 4.68 moles Chlorbenzene. As there are 7.35 moles, Chlorobenzene is the excess reactant and chloral the limiting reactant.

The theoretical moles of DDT produced = Moles DDT = 2.34 moles. The mass is (Molar mass DDT: 354,49 g/mol):

2.34mol * (354.49g / mol) = 830g DDT = Theoretical mass

Percent yield = Actual yield (464g) / Theoretical Yield (830g) * 100

Answer:

The new pressure of the gas is 1080 mmHg

Explanation:

The general equation provides a way to calculate the relationship between changesnp in volume, temperature and pressure of a given mass of gas.

The general gas equation is given as P1V1/T1 = P2V2/T2

Where P1 is initial pressure of gas

V1 is initial volume of gas

T1 is initial temperature of gas

P2 is final pressure of gas

V2 is final volume of gas

T2 is final temperature of gas

From the given question, P1 = 900 mmHg, V1 = 0.8 L, T1 = 400 K, P2 = ?, V2 = 0.5 L, T2 = 300 K

Making P2 subject of the general gas equations:

P2 = P1V1T2/V2T1

P2 = (900 × 0.8 × 300) / (0.5 × 400)

P2 = 1080 mmHg

Therefore, the new pressure of the gas is 1080 mmHg.
