The correct answer is the last option. Active metals will not react with acids in double replacement reactions. Instead, it reacts with metals via sing replacement reactions. It will displace hydrogen from the acid.

Well, each ml of water requires one calorie to go up 1 degree Celsius, so this liter of water takes 1000 calories to go up 1 degree Celsius. (There are 1000 ml, each of which needs to have its temperature raised.)

said law, the volume of a gas varies inversely with pressure. Boyle's law is
one of the gas laws we have. According to this law, at a fixed amount of an
ideal gas which is at constant temperature, the pressure and volume are
inversely proportional with each other. <span>The variables are volume and
pressure.</span></span>
