Answer:

The amount of H2SO4 in 2 litres is 560gm.

Explanation:

Given,

mass of sulphuric acid / volume of solution =28%

Therefore, mass of sulphuric acid in 100 ml solution is 28 grams.

We know that,

volume of solution is 2000ml.

Thus,

mass of sulphuric acid in 2000ml is

(28/100) ×2000

=28×20

=560gm

Thus, the mass of sulphuric acid is 560gm.

The correct name for the compound is written as lead II trioxonitrate V.

We know that a compound is formed when atoms are bonded together. The bond that holds atoms together could be ionic, metallic or covalent. We know that in  Pb(NO3)2, there is both ionic and covalent bonding.

This is because, the kind of bond between the lead II ion and the nitrate ion is an ionic bond while the bond between the nitrogen and the oxygen atoms in the nitrate ion is  covalent bond.

Explanation:

To find the volume, you need to (1) convert grams to moles (via molar mass) and then (2) calculate the volume (via molarity equation). The final answer should have 2 sig figs to match the sig figs of the given values.

(Step 1)

Molar Mass (NH₄NO₃): 80.043 g/mol

 25 grams NH₄NO₃                 1 mole
-------------------------------  x  -------------------------  =  0.312 moles NH₄NO₃
                                           80.043 grams

(Step 2)

Molarity = moles / volume

0.023 M = 0.312 moles / volume                <----- Insert values

(0.023 M) x volume = 0.312 moles             <----- Multiply both sides by volume

volume = 14 L                                               <----- Divide both sides by 0.023

Volume, in liters, of 0.023 M NH₄NO₃ solution can be made using 25 g NH₄NO₃ are 13.47L.

Molarity of a given solution is known as the total number of moles of solute per litre of the solution.  A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution.

Molarity = (No. of moles of solute ÷ Volume of solution in liters)

The unit of molarity is mol L⁻¹.

Molarity is temperature dependent because as temperature changes, volume of the solution also changes.

No. of moles of solute = Mass / Molar mass

No. of moles of solute = 0.31

Hence,

Volume of solution in liters = No. of moles of solute ÷ molarity

= 13.47 litres

Therefore, Volume, in liters, of 0.023 M NH₄NO₃ solution can be made using 25 g NH₄NO₃ are 13.47L.

H₂O would be the limiting reactant.

Balanced chemical equation:

6CO₂ + 6H₂O + light equation → C₆H₁₂O₆ + 6O₂

The amount of product that can be created is constrained by the reactant that is consumed first in a chemical reaction, commonly referred to as the limiting reactant (or limiting reagent).

Given

No. of moles of CO₂ = 18.6

Mass of H₂O = 2.38 × 10² g = 238g

No. of moles of H₂O = Given mass/ Molar mass

                                = 238 / 18 = 13.22 moles

Moles of H₂O = 13.22

According to the balanced chemical equation

6 moles of CO₂ react with 6 moles of H₂O

So the reactant that has less number of moles will be consumed first.

As the No. of moles of H₂O < No. of moles of CO₂

So, H₂O is the limiting reactant with 13.22 moles.

The term equilibrium constant refers to the number that often depict how much the process is able to turn the reactants in to products. In other words, if the reactants are readily turned into products, then it follows that the equilibrium constant will be large and positive.

Concentration of bromine = 0.600 mol /1.000-L = 0.600 M

Concentration of iodine = 1.600 mol/1.000-L =  1.600M

In this case, we must set up the ICE table as shown;

              Br2(g) + I2(g) ↔ 2IBr(g)

I          0.6            1.6           0

C      -x                -x             +2x

E    0.6 - x         1.6 - x       1.190

If 2x = 1.190

x = 1.190/2

x = 0.595

The concentrations at equilibrium are;

[Br2] = 0.6 -  0.595 = 0.005

[I2] =   1.6 - 0.595 = 1.005

Hence;

Let's see what I can come up with here. So chloroplasts are made up of several separate sections. They have the stroma (the liquid in which everything is contained) and the grana (plural of granum and is a stack of thylakoids). Chlorophyll is found in thylakoids.

The chlorophyll absorbs light (not green light since that is what is reflected to our eyes). Light energy is utilized to split water into hydrogen ions, electrons, and oxygen gas. With these ions and electrons, the electron transport chain, with the assistance of enzymes, produces ATP and NADPH. In all living cells, ATP is the primary source of energy. Because light is required to split water, this step of photosynthesis is known as the "light reaction."

The ATP and NADPH are transported into the stroma, where the "dark reaction" can take place. And, despite the name, it does not occur at night since our energy source does not store well. You've probably heard of the Calvin Cycle. The Calvin Cycle basically uses water, CO2, and the energy from earlier to generate carbohydrates, which are then stored in various ways. Glucose is the most well-known monosaccharide, although there are others, as well as countless polysaccharides such as cellulose and starch.
