Answer: Transpiration is a process process in which plants absorb the water through their roots and then release it in the form of water vapour through small pores located in the leaves of the plants.

Explanation:

Transpiration is very important for the life in our planet.

Transpiration is define as a process in which plants absorb the water through their roots and then release it in the form of water vapour.

The process of transpiration occurs through small pores which are located in the leaves of the plants.

Therefore, this process is essential to cool plants and it helps them to mantain their temperature.

The rate of transpiration depends on the following factors:

1. The humidity.

2. The light.

3. The temperature.

4. Water in the soil.

5. Wind.

6. Soil water.

Answer AND Explanation:

Transpiration is the process by which plants lose water in the form of water vapour into the atmosphere. Water loss from plants occurs at the following sites: stomata, cuticle and lenticels. Stomatal transpiration accounts for 80-90% of the total transpiration through stomata. Most stomata are found on the leaves but may occur on epidermis of young herbaceous plants. Cuticle transpiration occurs through cuticle and constitute 20%.

The iodide ion reacts with hypochlorite ion (the active ingredient in chlorine bleaches) in the following way:

LiRa [457]

Explanation:

(a) As the given chemical reaction equation is as follows.

$OCl^{-} + I^{-} \rightarrow OI^{-1} + Cl^{-1}$

So, when we double the amount of hypochlorite or iodine then the rate of the reaction will also get double. And, this reaction is "first order" with respect to hypochlorite and iodine.

Hence, equation for rate law of reaction will be as follows.

Rate = $K \times [OCl^{-}] \times [l^{-}]$

(b) Since, the rate equation is as follows.

Rate = $K [OCl^{-}][l^{-}]$

Let us assume that ( $[OCl^{-}] = [l^{-}]$ )

Putting the given values into the above equation as follows.

$1.36 \times 10^{-4} = K \times (1.5 \times 10^{-3})^2$

$1.36 \times 10^{-4} = K \times (2.25 \times 10^{-6})$

K = $\frac{1.36 \times 10^{-4}}{2.25 \times 10^{-6}}$

= $60.4 M^{-1}sec^{-1}$

Hence, the value of rate constant for the given reaction is $60.4 M^{-1}sec^{-1}$ .

(c) Now, we will calculate the rate as follows.

Rate = $K [OCl^{-}][l^{-}]$

= $60.4 \times (1.8 \times 10^{3}) \times (6.0 \times 10^{4})$

= $6.52 \times 10^{5}$

Therefore, rate when $[OCl^{-}] = 1.8 \times 10^{3}$ M and $[I^{-}]= 6.0 \times 10^{4}$ M is $6.52 \times 10^{5}$ .

Some amount of hydrogen peroxide (H2O2) breaks down to produce 3 molecules of oxygen (O2) and 6 molecules of water (H2O). How ma

soldier1979 [14.2K]

Answer:

$Atoms_H=12Atoms$

Explanation:

Hello,

In this case, the only source of hydrogen is in the 6 molecules of water, therefore, the atoms of hydrogen, by applying stoichiometry with the Avogadro's number is:

$Atoms_H=6moleculesH_2O*\frac{1molH_2O}{6.022x10^{23}moleculesH_2O}\frac{2molH}{1molH_2O}*\frac{6.022x10^{23}AtomsH}{1molH} \\Atoms_H=12Atoms$

Best regards.

How many grams of sodium chloride are present in a 0.75 M solution woth volume of 500.0 milliliters?

Aneli [31]

V = 500ml = 0,5 l
c = 0,75 M

c = n/V
n = c × V
n = 0,75 × 0,5 = 0,375[mol]

M NaCl = 58,5 g/mol

1 mol ------- 58,5 g
0,375 mol ----- x g

x = 0,375 mol × 58,5 g / 1 mol = 21,94 g

Answer: In this solution there are 21,94 g of sodium chloride.
