Distinguish Between matter and mass:

Matter:

Any substance that can occupy a space with some mass in it, is called as Matter.
Matter is visible.
Kilogram is its unit.
It is of three forms like liquid, solid, gas which is different in the physical form.
Matter is not constant and it keeps on changing into something new because of chemical reaction.

Mass:

The amount of matter that is contained in any object or space is called as Mass.
Mass is invisible. It can be quantified.
It has different units like volume, weight.
It has active gravitational mass, passive gravitational mass. and inertial mass and there is no difference in their forms.
Mass is constant and remains unchanged.

Identify the brønsted-lowry acid, the brønsted-lowry base, the conjugate acid, and the conjugate base in each reaction: (a) c5h5

Pie

acids give away protons (H+), bases accept protons, conjugate bases are what u get when when you take the protons from the acid, and conjugate acids are what u get when you add the protons to the base.

so for (a) the C5H5N is the base, water is the acid, C5H5NH+ is the conj acid, OH- is the conj base

(b) HNO3 is the acid, H2O is the base, hydronium ion is the conj. acid, NO3- is the conj base.

Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts wit

riadik2000 [5.3K]

Answer:

A) SiO2 is the limiting reactant

B) Theoretical yield= 72333.3g

C) % yield =91.5%

Explanation:

SiO2(s) + 2C(s) --------------> Si(s) + 2CO(g)

n(SiO2)= 155000/60 = 2583.33 mols

n(C)= 79000/12= 3291.66 mols

a)SiO2 is the limiting reactant

According to the balanced reaction equation,

60g of SiO2 produced 28g of SiO2

155000g of SiO2 will produce 155000×28/60= 72333.3g

Therefore theoretical yield of Si= 72333.3g

% yield= 66200/72333.3×100/1 =91.5%
