Answer:

The question is partially wrong. For spills of strong bases, such as sodium hydroxide, it must be neutralized with sulfuric or hydrochloric acid. Otherwise, for acid spills, neutralize them with sodium bicarbonate. The reactions are as follows:

Base spills: H2SO4 + 2NaOH → Na2SO4 + 2H2O

Sulfuric acid reacts with sodium hydroxide forming sodium sulfate and water.

Acid spills: H2SO4 + 2NaHCO3 → Na2SO4 + 2CO2 + 2H2O

Sulfuric acid reacts with sodium bicarbonate forming sodium sulfate, water and carbon dioxide.

Explanation:

For the destruction of strong inorganic bases such as sodium hydroxide (NaOH) they must be neutralized with a dilute solution of sulfuric acid or a dilute solution of hydrochloric acid.

For the destruction of strong inorganic acids such as sulfuric acid, they must be neutralized with an inorganic base such as sodium bicarbonate (NaHCO3)

NAHCO3 <span>doesn't help basic spills. It's slightly basic itself. It's good for acid spills though. It's not a very strong base so any leftover NaHCO3 won't be a hazard.
I DONT KNOW about h2so4</span>

Over a long period of time, an igneous rock changes into a sedimentary rock. Which of these actions must have affected the igneo
Alla [95]

Answer: The actions that must have affected the igneous rock in order to form the sedimentary rock is that (It must have been broken down into sediments).

Explanation:

Rocks are solid structures that occurs naturally which is made up of different minerals. There are three main types of rocks, these includes:

--> METAMORPHIC ROCKS: These are the type of rocks which are formed by temperature and pressure changes inside the Earth.

--> SEDIMENTARY ROCKS: these rocks are usually formed from pre-existing rocks through the process of weathering (breaking down) of rocks.

--> IGNEOUS ROCKS: these rocks are formed when molten magma cools beneath or above the earth surface.

The actions that must have affected the igneous rock in order to form the sedimentary rock is that the igneous rocks are broken down into smaller pieces by erosion and weathering processes. Sediments which are formed accumulates at the earth surface. Over a long period of time, these sediments builds successive layers on top of one another. The sediments near the base hardens to form sedimentary rocks. This justifies the statement as a correct option (It must have been broken down into sediments).

PLEASE HELP!!!<br><br> What is the mass of one lead atom in amu?
alexandr402 [8]

Answer: 207.2

Explanation:

In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10 -27 kilogram (kg), or 1.67377 x 10 -24 gram (g). The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus.
