<span>1)false a in chemical equilibrium concentration of reactant is equal to concentration of product
2)as here they said heat is added in product side means its endothermic reaction and in endothermic reaction on increasing temp. equilibrium shift towards forward direction so its true
3) B)as here mole are equal in reactant and product side that is 2 and if we increase pressure equilibrium shift in dat direction where no. of moles are less and here mole are equal so it will remain unaffected</span>
Answer is: 2) 117g.
2Na + Cl₂ → 2NaCl
Step 1: calculate amount of substance of sodium and chlorine.
n(Na) = m(Na)÷M(Na) = 46g ÷ 23 g/mol = 2 mol.
n(Cl₂) = m(Cl₂)÷M(Cl₂) = 71g ÷ 71 g/mol = 1 mol.
Step 2: calculate amount of substance and mass of sodium-chloride.
Because both sodium and chlorine react completely, we can use both n to compare with n of NaCl.
n(Na) : n(NaCl) = 2:2, 2 mol : n(NaCl) = 2:2
n(NaCl) = 2mol, m(NaCl) = 2mol ·5805 g/mol = 117 g.
Answer:
it is actually b because i did this i picked b and got it right
Explanation:
Answer:
The false statement is: 3. Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors
Explanation:
Gas is a state of matter, that has <u>less density than liquids and solids</u>. The gaseous particles have low intermolecular forces and thus they can move freely.
It is a very <u>compressible fluid</u> that has no fixed shape. Gas occupies the whole container in which it is stored, thus taking the shape of the container. Therefore, <u>the volume of the gas is equal to the volume of the container.</u>
<u>Polar liquid like water (H₂O) and nonpolar liquid like carbon tetrachloride, are immiscible. However, in the gaseous state, their vapors form a homogeneous mixture.</u>
