. Each year significant amounts of money are spent to prevent the corrosion of structural steel. It is inevitably a losing battle.
Answer:
mass of water is 7.43 g
Explanation:
q = mc∆T
qsteam = 100 g × 1.864 J/(g °C) × (110 – 100) °C = 1864 J
qwater = mwater× 4.184 J/(g °C) × (95 – 35) °C = mwater× 251.04 J/g = qsteam = 1864 J
mwater = 1864 J / 251.04 J/g = 7.43 g
Answer: Potassium is 39.10 g/mol
Explanation: The numbers below the element are the molar mass.
Answer:
False.
This is false because, no chemical reaction could possibly happen.
But in case of sodium it is highly reactive with water.......... so there will be a chemical reaction.
but as sodium is not a insoluble molecular compound this is not applicable to the situation.
