You did not post up the options, however we can balance this equation ourselves simply by adding multipliers to the front of each reactant and product until all atoms balance. Start with one atom type, say hydrogen, then move to the next and next and keep repeating this process.

2NH3 + O2 ⇒ 2NO + 3H2O

This balances nitrogens and hydrogens, but we still can't balance oxygen, so have to multiply up further

4NH3 + 5O2 ⇒ 4NO + 6H2O

This now balances all 3 atom types for reactants and products.

Explanation:

The portion of the serous membrane that covers and adheres to the lung is called visceral pleura

Pleura are the pair of membranous linings surrounding the lungs
The visceral pleura covers each lung surface, and the parietal pleura covers the inner surface of the thoracic cavity
The visceral pleura is a delicate membrane which dips into the fissures between the lobes of the lung
Pleura allows the lungs to move inside the body cavity without friction as friction would cause damage to the lungs and the tissue in the chest wall

A student measured the mass and volume of a metal sample using a triple beam balance and a graduated cylinder. The sample has a

alexdok [17]

Answer:

$d=3.79\ g/cm^3$

Explanation:

Given that,

The mass of a sample, m = 16.7 grams

Volume of the sample, V = 4.4 cm³

We need to find the density of the metal sample.

Density = mass/volume

Substituting all the values,

$d=\dfrac{16.7\ g}{4.4\ cm^3}\\\\=3.79\ g/cm^3$

So, the density of the metal sample is $3.79\ g/cm^3$ .

we will take cows as an example, they inhabit earth and so do we as humans. we as humans put the on our farms and our grass lands. we give the cows a biome. so that makes the statement true.

tell me if I am wrong. :)
