Reactants: H₂SO₄ + 2 NaOH
Products: 2 H₂O + Na₂SO₄
The answer is A.
The elements in the blocks of period 4-7 and group 3-12 in the periodic table are in the d-block and d-block elements are known as transition metals or transition elements.
Arsenic is a metalloid and it has four electron shells and five valence electrons.
the s and p orbital of Arsenic have 2 and 3 electrons respectively and which makes five valence electrons.
3 major groups are metals,metalloids, and the non-metals.
If the volume of 425 grams was 48.0 cm³, simply divide
g/cm³ = 425 g/48 cm³ = 8.85 g/cm³
If using water in water displacement, 1 mL = 1 cm³
8.85 g/cm³ = 8.85 g/mL
This density is most closely aligned with that of B. Copper

Fossil fuels are an important natural resource used by society and they are organic fuels derived from ancient plants and animals.
<h3>What are fossil fuels?</h3>
Fossil fuels are the natural resources means they are derived from the ancient resdue of plants and animale due to theor decomposition under high temperature and pressure.
- Fossil fuel may be present in solid, liquid as well as in gaseous form so the given option (a) is incorrect.
- This is the wrong assumption that in the fossil fuel we get the fossils of dinosaur, so option (c) is incorrect.
- They are not inorganic fuels infact they are organic fuels.
So, fossil fuels are organic fuels derived from ancient plants and animals.
