The secondary container must be marked with the name of the chemical and any hazards it may provide when a substance containing a hazardous chemical is moved from the primary container to the secondary container.
Define a secondary label.
The product's components, nutritional values, health and safety warnings, use instructions, manufacturer or supplier data, contact information, or comprehensive tracking and product information in a barcode format are all included on a secondary label.
The identity of the hazardous chemical contained in the product and the dangers, whether physical, health-related, or environmental, that the components present must both be disclosed on the secondary labels.

How many molecules are in 1. 8 g of H2O?.
There are approximately 6.022 x 10^22 (6.022 x 10²²) molecules in 1.8 grams of H2O.
To determine the number of molecules in 1.8 g of H2O, we first need to know the molar mass of H2O. The molar mass of H2O is 18.015 g/mol. To convert the mass of H2O to moles, we divide it by the molar mass:
1.8 g H2O / 18.015 g/mol = 0.1 mol H2O
Next, we use Avogadro's number (6.022 x 10^23) to convert moles to number of molecules:
0.1 mol H2O x 6.022 x 10^23 molecules/mol = 6.022 x 10^22 molecules
So, there are approximately 6.022 x 10^22 (6.022 x 10²²) molecules in 1.8 grams of H2O.
It is worth noting that, 1 mole of any substance contains Avogadro's number of entities of that substance. And Avogadro's number is a fundamental constant of nature which is used to express the number of atoms, ions, or other elementary entities in a given sample of a substance.

oxides of active metals, such as cao, react with water to form____
The oxides of active metals react with water to form metal hydroxides.
An active metal reacting with water produces a base. The first group of elements in the reactivity series is the most reactive metals. When they react with water, the plus charge on the metal is canceled by the negative charge of the hydroxide ion. Hence, there is a formation of the basic oxide.
Compounds such as calcium oxide (CaO) reacts with water to form calcium hydroxide. It is commonly known as slaked lime which is the end product of this process.
This is a type of combination reaction. Combination reactions are the types of reactions in which two reactants combine to form a new product and also release heat energy during the reaction.

What share of modern renewable energy supplies does hydroelectric power account for?.
The shares of modern renewable energy supplies in the Hydroelectric power is 22%.
The Hydropower technologies generate power by using the elevation difference created by a dam or diversion structure of water flowing. The Hydropower is the affordable source of electricity that costs less than others. Hydropower relies only on the energy from moving water. As compared to other electricity sources, hydropower has relatively low costs throughout in terms of maintenance, operations, and fuel. Hydropower's have longer lifespan with low costs. It is a reliable form of backup power during major electricity outages or disruptions. Hydroelectric power produces a number of benefits outside of electricity generation such as flood control, irrigation support, and water supply.
