I don’t know the exact answer but this information may help. :) The sun transfers energy to the grass by radiation, which they turn into energy through photosynthesis. They have 100% of the energy in a food chain. Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Energy is transferred into the food chain since the sun produces energy to plants and with that animals eat plants and so on.

. A reaction in which A, B, and C react to form products is first order in A, second order in B, and zero order in C. a) Write a

AleksAgata [21]

Answer:

a) r = k × [A] × [B]²

b) 3

Explanation:

Let's consider the following generic reaction

A + B + C ⇒ Products

The generic rate law is:

r = k × [A]ᵃ × [B]ᵇ × [C]ⁿ

where

r: reaction rate

k: rate constant

a, b, n: reaction orders

This reaction is first order in A, second order in B, and zero order in C. The rate law is:

r = k × [A]¹ × [B]² × [C]⁰

r = k × [A] × [B]²

The overall order of the reaction is the sum of the individual reaction orders.

1 + 2 + 0 = 3

What is the total energy change for the following reaction: CO + H2O -> CO2 + H2?

liubo4ka [24]

1)Delta H=(Delta H of reactants)-(Delta H of products)

2)And we know CO have 3 bond CO and CO2 have 2 bond that each of them are 2 bond, please see the picture!

so lets answer it:

$(3 \times 358) + (2 \times 463) - (4 \times 358) - 436 = 132$

A quantity of energy equal to 8.90 × 1012 joules was emitted from a nuclear reaction. What amount of mass was required to be con

Nataly [62]

E = mc^2
E = 8.90 * 10^12 Joules
c = 3 * 10^8 m/s
m = ????

8.90 * 10^12 = m * (3 * 10^8)^2
8.90 * 10^12 = m * 9 * 10^16
9.889 * 10^-4 kg = m <<<<< answer
