Explanation:

Energy pyramid refers to the representation of how the energy is transferred in the organism at each level in an ecosystem. The producers are kept at the lower level whereas the top carnivore at the top.

1. The energy linearly flows in the energy pyramid which can be represented in the form of the food chain. In a food chain, the energy flows when one organism eats another organism which after digestion provides energy.

2. the energy is transferred in a  food chain according to ten per cent law which states that only ten per cent of energy will be transferred between the organism in a food chain.

An unknown substance is obtained by police. The forensics laboratory has
timurjin [86]

Answer:

70.0 %

Explanation:

Step 1: Given data

  • Mass of nitrogen (mN): 74.66 g
  • Mass of the compound (mNxOy): 250 g

Step 2: Calculate the mass of oxygen (mO) in the compound

The mass of the compound is equal to the sum of the masses of the elements that form it.

mNxOy = mN + mO

mO = mNxOy - mN

mO = 250 g - 74.66 g = 175 g

Step 3: Determine the percent composition of oxygen in the sample

We will use the following expression.

%O = mO / mNxOy × 100%

%O = 175 g / 250 g × 100% = 70.0 %
