Can someone define these for me

Chemistry

Answer:

These are all in order....

Explanation:

- closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system

- a solute is a substance dissolved in another substance, known as a solvent

- A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid

- a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent)

- a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy

- a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.

- Half-life is the time required for a quantity to reduce to half of its initial value

- the determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains. The ratio between them changes as radioactive carbon-14 decays and is not replaced by exchange with the atmosphere.

- any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed

How many grams of aluminum are required to give a total dislocation length of 3,000 miles (enough to stretch from New York City
Luba_88 [7]

Answer:

0.13 g

Explanation:

mass of aluminum required = ( Dislocation length) / ( Dislocation density) × (density of metal)

3000 miles to cm (  1 mile = 160934 cm) = 3000 miles ×  160934 cm / 1 mile = 482802000 cm

density of Aluminium = 2.7 g /cm³

dislocation density of aluminum = 10¹⁰ cm³

mass of aluminum required = (482802000 cm × 2.7 g/cm³) / 10¹⁰ cm³ = 0.13 g

Which statement best describes chemical properties of matter? Chemical properties, such as density, must be observed when a subs
alisha [4.7K]
Chemical properties of matter can only be observed and measured by performing a chemical change.
- Density and boiling are not chemical changes.
- This leaves reactivity and combustion. Reactivity does not need to be observed at STP so the statement is wrong.

Combustion is the best answer.

Which of the following particles are the least massive in comparison to the others?
Gekata [30.6K]

Answer:

The majority of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom's constituent particles, with a mass of 9.11 x 10-31 kg and a size too small to be measured by current techniques.
