Answer is: Reactants: 2VCl2 and 3Cl2; product: 2VCl5.
Balanced chemical reaction: 2VCl₂ + 3Cl₂ → 2VCl₅.
According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.
There are ten chlorine atoms and two vanadium atoms on both side of balanced chemical reaction.
Answer:
Creativity
Skepticism
Reasoning
Explanation:
Scientists must see a creative way to solve problems in the world. Scientists must also be skeptic about what is said, because if they were not, no one would disagree and the problems would never be solved. Reasoning is a must, as reasoning is involved in the scientific process and writing conclusions to their studies.
Hope this help!
<span>You will use an ideal gas equation here. Let us denote 'x' as the unknown sample of zinc if another 1 ml of it is added to make a total of 476mL gas. The ideal gas equation is PV = nRT. Assume atmospheric conditions and then substitute everything to the equation.
(1atm)(0.476L) = (1.85 + x)(0.08206 L-atm/mol-K)(20.5+273K)
x = 1.83 g of zinc</span>
<u>Answer:</u>
The correct answer option is a) collisions between the particles and surrounding molecules.
<u>Explanation:</u>
The collisions between the particles and surrounding molecules causes the Brownian motion of particles in a colloid.
Brownian motion is the irregular movement of the microscopic particles in a fluid which bombard into each other.
It basically is the result of the molecules of a dispersion medium colliding with the dispersed particles of the phase.
