Salt dissolving in water is usually considered to be a physical change so I’m pretty sure it’s that sorry if I’m wrong
Answer:2H₂+ O₂→ 2H₂O the reactants are 2H₂ and O₂ ... if the theoretical yield is 95 g of water after the chemical reaction you may have only 45g of water
i think
Explanation:
True
Explanation:
Ionic compounds are chemical compounds that dissociates into positive and negative ions and are globally neutral due to the charge balance. They are made up of metals and non-metals.
- Ionic bonds are formed between two kinds of atoms having a large electronegativity difference.
- It is usually between metals and non-metals.
- The formation of this bond type involves the transfer of electrons from the less electronegative atom such that the two kinds of atoms now have completely filled outer shell like the noble gases.
- This transfer makes the metal positively charged while the non-metal becomes negatively charged.
- The atoms forms ions that are oppositely charged.
- The charges are balanced out leaving a net neutral compound.
- The electrostatic force of attraction between these ions is the ionic or electrovalent bond.

Answer:
7.61 liters
Explanation:
From the question,
Applying Charles law formula,
V₁/T₁ = V₂/T₂...................... Equation 1
Where P₁ = initial volume of of air, V₂ = Final volume of air, T₁ = Initial Temperature of air, T₂ = Final Temperature of air.
make V₂ the subject of the equation
V₂ = (V₁×T₂)/T₁............... Equation 2
Given: V₁ = 5 liters, T₁ -35 °C = (-35+273) K = 238 K, T₂ = 89°C = (89+273) K = 362 K
Substitute these values into equation 2
V₂ = (5×362)238
V₂ = 1810/238
V₂ = 7.61 liters
