Answer:

it is none of them here is how photosynthesis

Explanation:

the plant takes water, light energy, and carbon dioxide

then the plant makes sugar(also the sugar is called glucose) and oxygen and the oxygen leave the plant that is how photosynthesis work and if animals make carbon dioxide then to resive oxygen then they need to plant a plant seen and wait for multiple days

6.45 g of C6H12O6 is burned in a bomb calorimeter containing 950. g of water and the temperature goes from 35.0∘C to 42.3∘C. If

emmasim [6.3K]

Answer:

$q_{rxn}=-488.86\frac{kJ}{mol}$

Explanation:

Hello!

In this case, since this calorimetry problems can by analyzed by figuring out that the heat lost due to the combustion of C6H12O6 is gained by the water and the calorimeter which undergo the mentioned temperature rise, we can write:

$Q_{rxn}=-(m_wC_w+C_c)(T_2-T_1)$

Thus, by plugging in the given data, we obtain:

$Q_{rxn}=-(950.0g*4.184\frac{J}{g\°C} +933\frac{J}{\°C})(42.3\°C-35.0\°C)\\\\Q_{rxn}=-17.5kJ$

Next, we compute the moles of C6H12O6 by using its molar mass (180.18 g/mol) as shown below:

$n=6.45g*\frac{1mol}{180.18g} =0.0358mol$

Thus, the value for q of the reaction turns out:

$q_{rxn}=\frac{Q_{rxn}}{n} \\\\q_{rxn}=\frac{17.5kJ}{0.0358mol} \\\\q_{rxn}=-488.86\frac{kJ}{mol}$

Best regards!

Calculate the concentration of OH- in a solution that contains 3.9 x 10-4 M H3O+ at 25°C. Identify the solution as acidic, basic

aalyn [17]

Answer:

[OH⁻] = 2,6x10⁻¹¹

Acidic

Explanation:

The kw in water is:

2 H₂O(l) ⇄ OH⁻(aq) + H₃O⁺(aq)

kw = [OH⁻] [H₃O⁺] = 1,00x10⁻¹⁴

If concentracion of H₃O⁺ is 3,9x10⁻⁴M:

[OH⁻] [3,9x10⁻⁴M] = 1,00x10⁻¹⁴

[OH⁻] = 2,6x10⁻¹¹

pH is defined as - log[H₃O⁺]. If pH>7,0 the solution is basic, if pH<7,0 solution is acidic, if pH=7,0 solution is neutral.

In this problem,

pH = - log [3,9x10⁻⁴M] = 3,4

As pH is < 7.0, the solution is acidic

I hope it helps!

All the molecules of a substance possess the "average kinetic energy" value.

MaRussiya [10]

Answer:

true

Explanation:

when molecules of a solid substance is vibrating so, it means they are possessing average kinetic energy. thus, we can conclude that the statement all the molecules of a substance posses the average kinetic energy value is true.
