<span>The answer is D. atmosphere. There are four spheres of the Earth: 1. Geosphere (from Greek word 'geo' = ground), 2. Hydrosphere (from Greek word 'hydro' = water), 3. Biosphere (from Greek word 'bio' = life), and 4. Atmosphere (from Greek word 'atmo' = air). A magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. Through the process of elimination, since lightning is present in the air, it can be found in the atmosphere. </span>

Answer:

it is atmosphere

Explanation:

because A magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. Through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.

If 28 mL of 6.2 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?
Naddika [18.5K]

Answer:

The answer is 30 g of sodium hydrocarbonate

Explanation:

This is a acid-base reaction, so in order to neutralise the spilled acid, the mol of spilled acid should be calculated.

M = n / V => n = M x V = 0.028 x 6.2 = 0.1736 mol

Since 1 mol of sulfuric acid generates 2 mol of H⁺, so the mole of H⁺ is 0.3472 mol or 0.35 mol with two significant figures.

To neutralized the acid, we need at least the same mole of base, so we need at least 0.35 mol of NaHCO₃, which can be converted to its mass at 29.4 g.

Since the answer need to be expressed in two significant figures and also need to make sure to neutralize all the acid, so we will use a little excess base. The answer is 30 g.
