Answer:

D. All of the above

Explanation:

E = MC² is a common equation in physics.

E is energy

M is mass

C is the speed of light

The law was stated by Albert Einstein.

From this law, it was shown that energy is released when matter is destroyed.
Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.

Which of the following leads to a higher rate of diffusion?

miv72 [106K]

<h3>Answer;</h3>

Higher velocity of particles

<h3>Explanation;</h3>

The diffusion rate is determined by a variety of factors which includes;

Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.

The chemical formula for strontium sulfite is SrSO3. TRUE FALSE

VLD [36.1K]

Valency is the number of electrons lost or gained by an atom to attain an stable configuration. Valency is important when writing the formula of chemical compounds in chemistry. Strontium has a valency of 2 while sulfite ion (radicle) has a valency of 2. Therefore, the chemical formula of strontium sulfite is written as SrSO3.
