False, I’m like 99% sure :)
Answer:
D. All of the above
Explanation:
Hazardous waste is defined as waste that comprises organic or inorganic components or compounds that may have a negative influence on human health or the environment due to the waste's intrinsic physical, chemical, or toxicological characteristics.
Correct Option Is D. All of the above.
Liquids, solids, and enclosed gases can all be hazardous waste. Hazardous substances have one or more of the following characteristics: they are combustible, corrosive, lethal, or reactive. They can be waste from manufacturing operations, discarded used materials, or unused commercial products like cleaning fluids (solvents) or insecticides that have been discarded.
Answer:
a) 0.56moles
b) 2.78moles
Explanation:
The number of moles can be calculated by using the formula;
Mole (n) = Mass (M) ÷ Molar mass (MM)
For a glucose molecule, with chemical formula: C6H12O6
Where atomic mass of C= 12, H=1, O= 16
Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)
= 72 + 12 + 96
= 180g/mol
a) In 100g of glucose;
Mole = 100/180
Mole = 0.56moles
b) In 500g of glucose
Mole = 500/180
Mole = 2.78moles
The answer would be algae or phytoplankton
Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organs, and have no body symmetry.
The shapes of their bodies are adapted for maximal efficiency of water
flow through the central cavity, where it deposits nutrients, and leaves
through a hole called the osculum. Many sponges have internal skeletons of spongin and/or spicules of calcium carbonate or silicon dioxide. All sponges are sessile
aquatic animals. Although there are freshwater species, the great
majority are marine (salt water) species, ranging from tidal zones to
depths exceeding 8,800 m (5.5 mi).
