Explanation:
Acid seems like it would have more ph
Answer: R
Explanation: is polarized to the right
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Hydrogen reduces the oxides of the less active metals, viz. removes oxygen from strongly heated metal oxides when passed over them, and in the process gets oxidized itself to water.
Both alkali metals and Hydrogen acts as a reducing agent which is proved by the following reactions:-
CuO + H2 Cu + H2O
CuO + 2Na Cu + Na2O
In both cases CuO is oxidised.
Answer:
3.0x10¹⁹ atoms
Explanation:
First we <u>convert 10 mg of mercury into grams</u>:
Then we <u>convert 0.01 g of mercury into moles</u>, using its <em>molar mass</em>:
- 0.01 g ÷ 200.59 g/mol = 4.99x10⁻⁵ mol
Then we <u>convert moles into number of atoms</u>, using <em>Avogadro's number</em>:
- 4.99x10⁻⁵ mol * 6.023x10²³ atoms/mol = 3.0x10¹⁹ atoms
