It would be the very first response. A. How do atoms combine to form new substances.
Answer:
compound is a material formed by chemically bonding two or more chemical elements.
Explanation:
Answer:
Explanation:
In calorimetry we apply the formula
heat lost = heat gained
m₁ x s₁ t ₁ = m₂ x s₂ t ₂
here t₁ and t₂ are change in temperature . suppose s₁ denotes specific heat of metal a nd s₂ denotes specific heat of water .
If s₁ is far less than s₂ , t₁ will be far more than t₂ , to balance the two sides
Hence change in temperature of metal pot will be more than change in temperature of water.
Final temperature will be far away from temperature of the metal pot.
Final temperature will be closer to temperature of water.
Answer:
Barium and Calcium
Explanation:
When heated with chlorine,
Both calcium and barium are able to form ionic bonds.
Hydrogen can only form bonds that are partial positive. It is not strong enough to be considered an ionic bond.
Silicon forms strong covalent with chlorine, called silicon tetrachloride. The structure is in diamond form which requires a lot of heat energy to break the bonds are way more than energy needed to break the bonds between calcium chloride.
Krypton is an inert element which does not form bonds with any elements under standard conditions
