Answer: C6H12O6 + 6O2 -> 6CO2 + 6H2O. Yields 2755 kJ/mole of glucose. The reverse of this reaction – combing carbon dioxide and water to make sugar – is known as photosynthesis. Photosynthesis is the process responsible for storing all the energy we extract from fossil fuels, crops, and all of our food.

What is the pH of a solution with a H+ ion of 2×10-¹²?

kap26 [50]

Answer:

11.7

Explanation:

The pH is the negative logarithm of the concentration of H+ ions. If the concentration is 2×10-¹² the the pH will be -log(2×10-¹²) which is 11.698 which can be round up to 11.7.

In experiment 1, how many moles of benzoic acid are present? how many moles of sodium bicarbonate are contained in 1 ml of a 10%

nexus9112 [7]

First, let us calculate the moles of solute or sodium bicarbonate is in the 1 ml solution.

moles = 1 mL * (1 g / 9 mL) = 0.11 moles

The molar mass of sodium bicarbonate is 84 g/mol, therefore the mass is:

mass = 0.11 moles * 84 g/mol

mass = 9.33 g

A chemical reaction involves reactant species A, B, and C. Leaving all other factors identical, doubling the concentration of sp

umka21 [38]

Answer:

Rate = k . [B]² . [C]

Explanation:

The dependence of the reaction rate on the concentration of the reactants is given by the reaction order of each one, as shown in the rate equation.

$Rate=k.[A]^{x} .[B]^{y} .[C]^{z}$

where,

k is the rate constant

x, y, z are the reaction orders.

The rate of reaction is not affected by changing the concentration of species A. This means that the reaction order for A is x = 0 since when its concentration changes, the rate stays the same.

Leaving all other factors identical, doubling the concentration of species B increases the rate by a factor of 4. This means that the reaction order for B is y = 2, so when the concentration is doubled, the new rate is 2² = 4 times the initial rate.

The rate of the reaction is linearly dependent on the concentration of C. This means that the reaction order for C is z = 1, that is, a linear dependence.

All in all, the rate equation is:

Rate = k . [B]² . [C]
