an ancient study or art which attempted to combine science and philosophy to solve worldly problems
a homogeneous mixture of elements with metals to form metallic solids
the simplest unit of an element that still retains the properties of that element
two or more elements joined together such that the elements have lost their individual identity
a primary substance that cannot be divided into separate substances
the group of elements that are good conductors of electricity and heat
the group of elements that are poor conductors of electricity and heat
answer: option (c) is the correct answer.
catalyst are the substances which in increasing the rate of a chemical reaction without itself getting consumed.
a catalyst changes the path of a reaction by lowering the activation energy level so that molecules with low energy can easily participate in the reaction and thus, formation of products become fast.
thus, we can conclude that out of the given options, a catalyst increase the speed of a reaction as the catalyst makes it easier for the activated complex to form, lowering the activation energy.
there are 6.022 x 10^23 formula units per mole
2.41 x 10^24 / 6.022 x 10^23 = 4.00 moles
answer: the micro-moles of copper (ii) fluoride is
molarity of a solution is defined as the number of moles of solute present in 1 liter of solution.
we are given:
molarity of solution =
moles of solute = ? moles
volume of the solution = 50 ml = 0.05l (conversion factor: 1l = 1000ml)
putting values in above equation, we get:
to convert it into micro-moles, we multiply it by
converting into micro-moles:
hence, the micro-moles of copper (ii) fluoride is
