Answer:
Concept: Chemical Analysis
- Higher humidity indicates a higher concentration of water molecules and hence a higher statistical probability of rain.
- Hence Fred in Kentucky will need an umbrella tomorrow due to the humidity and stratus clouds.
- Give brainlist.
The density of water is about 1kg/m³, therefore is the substance has a density of less than 1kg/m³ then it will most likely float however if it is more than 1kg/m³ then it will most likely sink.
Answer:
A Light Emitting Diode (LED) is a solid-state semiconductor device that converts electrical energy directly into light. On its most basic level, the semiconductor is comprised of two regions.
Explanation:
In the answer
Answer:
2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2
Explanation:
Iron is a metallic element with chemical symbol, Fe while concentrated sulphuric acid is a chemical compound with chemical formula, H2SO4. Both are involved in a chemical reaction as follows:
Fe + H2SO4 → Fe2(SO4)3 + H2
However, this reaction is not balanced as the number of moles of each atom in both the reactants and product side is not equal. To balance the equation, we have to ensure that each number of atom is equal. The balanced equation are as follows:
2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2
