Answer:

The correct answer for the reverse reaction is the third option starting from top.

Explanation:

If we examine the given chemical equation:

2SO2 + O2 ⇌ 2SO3

The double arrow indicates that the reaction goes in both directions:

2SO2 + O2 -> 2SO3

2SO3 -> 2SO2 + O2

However, the closest option for the real situation would be the product from the semirreaction reacting in turn with oxygen:

2SO3 + O2 -> 2SO2

Thus, the correct answer is the third.

Answer:

2SO3 -> 2SO2 + O2 (not shown in the options)

Explanation:

In a reversible reaction, reactants react to produce products and products react to produce reactants, simultaneously.

Given the reversible reaction:

2SO2 + O2 ⇌ 2SO3

It has a forward reaction:

2SO2 + O2 -> 2SO3

and a reverse reaction:

2SO2 + O2 <- 2SO3

Please Help! It says fill in the blanks to complete the Punnett square below to show the results of a cross between a homozygous
makkiz [27]

Answer:

Genotypes: Homozygous (GG)=50%, Heterozygous (Gg)=50%.

Phenotypes: Homozygous gray (GG)=50%, Heterozygous gray (Gg)=50% or just Gray=100%

Explanation:

Hello,

The Punnett square for this cross turns into:

\left[\begin{array}{ccc}&G&g\\G&GG&Gg\\G&GG&Gg\end{array}\right]

It means that the genotypes and phenotypes are:

Genotypes: Homozygous (GG)=50%, Heterozygous (Gg)=50%.

Phenotypes: Homozygous gray (GG)=50%, Heterozygous gray (Gg)=50% or just Gray=100%

Best regards.

What do plants do that requires Energy?
Kruka [31]

Answer:

Photosynthesis

Explanation:

Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen. The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.

A chemist has a block of lead metal (density is 11.3 g/mL). The block weighs 2.10g. What is the volume if the lead block in mL?
mezya [45]

The volume of a block of lead metal that has a density of 11.3g/mL and weighs 2.10g is 0.186mL.

<h3>How to calculate volume?</h3>

The volume of a substance can be calculated by dividing the mass of the substance by its density. That is;

Volume = mass ÷ density

According to this question, a chemist has a block of lead metal (density is 11.3 g/mL). The block weighs 2.10g.

Volume = 2.10g ÷ 11.3g/mL

Volume = 0.186mL

Therefore, the volume of a block of lead metal that has a density of 11.3g/mL and weighs 2.10g is 0.186mL.
