Answer:
1& 4
Explanation:
1. The average kinetic energy of the particles in a substance determines the substance's temperature.
4. How fast a substance's particles are moving determines how hot or cold the substance is.
Answer:
Mole = 2.67
Given data:
Number of atoms of carbon = 1.61 × 10²⁴
Avogadro's Number = 6.023 × 10²³
Required:
Moles = ?
Solution:
Formula for calculating moles from particle numbers is given as,
Mole = Number of particle / Avogadro's number
putting values
Moles = 1.61 × 10²⁴ / 6.023 × 10²³
Moles = 2.67
Answer:
Silicon
Explanation:
One of the most similar elements to carbon on periodic table is silicon. Several compounds formed between carbon or silicon and other elements are identical.
Carbon is an element found in life forms as a building block while silicon is a building block of machine components such as semiconductors
Silicon is an element that can sustain bonds, similar to carbon bonds and it is situated directly under carbon on the periodic table
Energy flows into an ecosystem in the form of light and exits in the form of heat
