<span>The Law of Conservation of Mass simply states
that the total amount of mass should not change in a chemical reaction that is
isolated (no other objects can enter the reaction). The total mass of the
reactants must be equal to the total mass of the products. Thus, t</span>he correct estimate of
the amount of oxygen used in the interaction is the difference between 133
g and 29 g.
Answer:
The correct option is;
b. The particles are positively and negatively charged, have high compressibility, and spread out to fill a container
Explanation:
Plasma are gases that contain positively and negatively charged particles. Therefore, plasma flow drift in space such that plasma. like gases has no characteristic shape or volume but takes the shape and fills the entire volume of a container in which it is placed
Other characteristics of plasma are that plasma is a conductor of electricity and magnetic fields can therefore exist in plasma due to the fact that plasma are made of atoms in which part or all of the electrons have been removed leaving the ions to roam freely in a container.
The heat required to heat 9.61g of ethanol from 24.1 c to 67.3 c is calculate as below
Q(heat) = M(mass) xC (specific heat capacity ) x delta T (bhange in temperature)
Q=?
M=9.61 g
C= 2.46 j/g/c
deltaT =67.3c - 24.1 = 43.2 c
Q is therefore= 9.61 g x 2.46 j/g/c x 43.2 c = 1021.27 joules
<span>I think the best answer
among the choices is the third option. The properties which make tungsten
useful in the thin, glowing filaments of light bulbs are it has a high melting
point and is electrically conductive. Its melting point is around 1650 degrees
Celsius. Of all metals, it is the highest and also it does not melt even though
it is glowing.</span>
Answer:
Fe will displace On but no the reaction is not vigorous.
