What human made mechanisms are responsible for increasing the rate of global warming??

Determine whether the material is a mineral or a non-mineral based on the description

almond37 [142]

Answer:

Calcium is homogeneous Three percent of Earth's crust is made of calcium Mineral
Glycerin is a viscous liquid at room temperature. Non-mineral
Emerald is hard and does not decay. Its chemical formula is Be3Al2(SIO3)6 Mineral
Chlorophyll is produced in plants during photosynthesis Non-mineral

Explanation:

Minerals are generally solid and inorganic substances, with defined crystalline structures, that exist in the earth's crust, formed by one or more chemical elements.

Calcium is the fifth element in abundance in the earth's crust, it is found forming mineral compounds such as calcite and dolomite or rocks such as marble, limestone and dolomite.

Glycerin is a colorless, slimy and sweet-tasting substance that is obtained from animal and vegetable fats and oils. According to its characteristics, it does not have a solid structure, which is why it is considered a non-mineral.

Emerald is a cyclic silicate of beryllium and aluminum whose chemical formula is Be3Al2(SiO3)6, it has a well-defined crystalline structure.

Chlorophyll is a green pigment that is present in the leaves and stems of many vegetables and is responsible for the photosynthesis process; does not have a crystalline structure defined by what is considered a non-mineral.

Answer:

Has potential energy

Explanation:

A pendulum tend to have maximum potential energy at maximum displacement....so as it moves from the max displacement to the other side...the potential energy is converted to kinetic energy...which is maximum at the lowest position...in which the kinetic energy is converted back to potential energy as the pendulum approaches the top again

Which substance is an inorganic compound

saul85 [17]

An inorganic compound is a substance that does not contain both carbon andhydrogen. A great many inorganic compounds do contain hydrogenatoms, such as water (H2O) and the hydrochloric acid (HCl) produced by your stomach. In contrast, only a handful of inorganic compounds contain carbon atoms.

It is known that 32g of oxygen takes up 24 litres of space at 25oC. Calculate the volume of oxygen that is needed to react compl

Gwar [14]

6 L of oxygen (O₂)

Explanation:

We have the following chemical reaction:

2 Mg + O₂ → 2 MgO

Now we calculate the number of moles of magnesium:

number of moles = mass / molar weight

number of moles of Mg = 12 / 24 = 0.5 moles

Taking in account the chemical reaction we devise the following reasoning:

if 2 moles of Mg react with 1 mole of O₂

then 0.5 moles of Mg react with X moles of O₂

X = (0.5 × 1) / 2 = 0.25 mole of O₂

mass = number of moles × molar weight

mass of O₂ = 0.25 × 32 = 8 g

Knowing the information given by the problem that 32 g of O₂ takes up 24 liters of space, we devise the following reasoning:

if 32 g of O₂ takes up 24 liters of space

then 8 g of O₂ takes up Y liters of space

Y = (8 × 24) / 32 = 6 L of O₂
