1 L ------- 1000 cm³
1.45 L ----- ???
1.45 * 1000 = 1450 cm³ ( volume )
Density = 0.710 g/cm³
mass = in Kg
m = D * V
m = 0.710 * 1450
m = 1029.5 g
1 Kg ------- 1000 g
kg -------- 1029.5 g
mass = 1029.5 / 1000
mass = 1.0295 Kg
hope this helps!
Answer:
Your answer would be D, they are all non-renewable energy sources. Hope this helps!
Explanation:
The visible light is a part of the electromagnetic spectrum with the range of 400nm to 700nm.
Visible light is made up of all the colors we can perceive.
- The electromagnetic spectrum is a series of radiation.
- The most energetic have the highest frequency and lowest wavelength.
- The visible light is part of the spectrum.
- It is the part of the spectrum that allows for sight.

Answer:
D. F
Explanation:
Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
The electron affinity values of the following elements is given;
Electron Affinity of Hydrogen is 72.8 kJ/mol.
Electron Affinity of Lithium is 59.6 kJ/mol
electron affinity of carbon is 153.9 kJ mol‑1
Electron Affinity of Fluorine is 328 kJ/mol
The electron affinity of neon is 0 kJ mol‑1.
When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.
Nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
That explains why florine seems to have the highest electron affinity value.
