A 1-L sample of CO initially at STP is heated to 546 K, and its volume is increased to 2 L.
pantera1 [17]

A 1 L sample of CO initially at STP is heated to 546 K, and its volume is increased to 2 L, the final pressure of CO is 1 atm.

We have,

Initial volume, V₁ = 1 L

Final volume, V₂ = 2 L

Initial temperature, T₁ = 273 K (standard temperature)

Final temperature, T₂ = 546 K

Initial pressure, P₁ = 1 atm

Final pressure, P₂ = ?

To calculate final pressure, we will use combined gas law.

Combined gas law is given as -

                                               <u>P₁V₁</u> = <u>P₂V₂</u>

                                                 T₁        T₂

where,

P₁ = initial pressure

P₂ = final pressure

V₁ = initial volume

V₂ = final volume

T₁ = initial temperature

T₂ = final temperature

Substituting values in the gas law equation -

<u> 1 x 1 </u> = <u>P₂ x 2</u>

273       546

P₂ = <u> 546 x 1 x 1</u>  atm

          273 x 2

P₂ = 1 atm

Therefore, the final pressure of sample of CO at STP is 1 atm.

The chemical equation of photosynthesis includes 6o2. which best describes this substance?
LenaWriter [7]

The chemical equation of photosynthesis includes 6O_{2}. -----a gas produced during photosynthesis best describes this substance

Elaborate:

During photosynthesis plants use carbon dioxide, water and sunlight to make sugar (glucose) and a waste product, oxygen gas.

the equation of this process can be:

6 CO_{2} + 6 H_{2} O + light energy  →  C_{6} H_{12} O_{6} + 6 O_{2}

carbon dioxide + water + light  →   glucose + oxygen

Is 6O_{2} a product of photosynthesis?

In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced.

What happens to sugar water oxygen and carbon dioxide during photosynthesis?

During photosynthesis, plants take in carbon dioxide  and water  from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

across a period, how does the electronegativity of a nonmetal affect the acidity of its binary hydride
goblinko [34]
1) Across the period as one moves from left to right, atomic size decreases.

2) Consider 3rd period elements containing non-metal i.e Si, P, S and Cl.

3) Here, atomic radius of these elements are in following order Si>P>S>Cl.

4) However, electronegative of these elements increases as we move from left to right

5) Thus, the corresponding hydrides have higher electro-negativity difference,as one moves from left to right.

6) Due to this, bond polarity increases from left to right,

7) Increase in bond polarity, results in increasing proton donating capability.

8) Therefore, acidity increases as one moves along the period.
