Which compound is produced during regeneration?
abruzzese [7]

The answer is RuBP.

<span>
Calvin Cycle consists of three stages:
1. fixation: the enzyme RuBisCO incorporates (fixes) carbon-dioxide into 3-PGA.
2. reduction: 3-PGA is reduced using NADPH as electron supply.
<span><u>3. regeneration: RuBP is regenerated and starts the cycle again.</u></span></span>

Sergeu [11.5K]

Answer:

The correct answer is "11.44 ml".

Explanation:

Molarity,

= 0.2 M

Density,

= 1.05 g/ml

Volume,

= 1 L

As we know,

⇒  Molarity=\frac{No. \ of \ moles }{Volume \ of \ solution}

or,

⇒  No. \ of \ moles=Molarity\times Volume

On putting the values, we get

⇒                         =0.2\times 1

⇒                         =0.2 \ moles

Now,

⇒  No. \ of \ moles=\frac{Mass \ taken}{Molecular \ mass}

or,

⇒  Mass \ taken=No. \ of \ moles\times Molecular \ mass

⇒                      =0.2\times 60.05

⇒                      =12.01 \ gram

hence,

⇒  Density= \frac{Mass }{Volume}

or,

⇒  Volume=\frac{Mass}{Density}

⇒                =\frac{12.01}{1.05}

⇒                =11.44 \ ml

Write and balance the following equation:
Maru [420]

Answer:

Sulfur reacts with oxygen to form sulfur dioxide. When nonmetals reactwith one another, the product is a molecular compound. Often, the nonmetal reactants can combine in different ratios and produce different products. Sulfur can also combine with oxygen to produce sulfur trioxide.

When 45 g of an alloy, at 25oC, are dropped into 100.0 g of water, the alloy absorbs 956 J of heat. If the final temperature of
taurus [48]

Answer:

The answer to the question is

The specific heat capacity of the alloy = 1.77 J/(g·°C)

Explanation:

To solve this, we list out the given variables thus

Mass of alloy = 45 g

Initial temperature of the alloy = 25 °C

Final temperature of the alloy = 37 °C

Heat absorbed by the alloy = 956 J

Thus we have

ΔH = m·c·(T₂ - T₁) where  ΔH = heat absorbed by the alloy = 956 J, c = specific heat capacity of the alloy and T₁ = Initial temperature of the alloy = 25 °C , T₂ = Final temperature of the alloy = 37 °C  and m = mass of the alloy = 45 g

∴ 956 J = 45 × C × (37 - 25) = 540 g·°C×c  or

c = 956 J/(540 g·°C) = 1.77 J/(g·°C)

The specific heat capacity of the alloy is 1.77 J/(g·°C)
