Explanation:
The total mass of the product will also be 20g because in chemical reactions, mass is always conserved.
According to the law of conservation of mass "the law states that matter can neither be created nor destroyed but changed from one form to another in a chemical reaction".
- The law simply postulates that mass is conserved in chemical reactions.
- If the mass of reactants is 20g, the mass of the products will likewise be 20g.
- So, the mass is the same in both directions.
Answer:
a. Thermal energy in transit due to spatial temperature difference .
Explanation:
Heat transfer -
Heat transfer is the exchange of the thermal energy or heat in between any physical systems .
It is the flow of energy or any form of energy from one system to another .
Heat transfer is divided into various mechanism , one of which is the thermal .
The thermal energy is the transit due to the spacial temperature difference .
What kind of question is that it’s Hot
Answer:
Silicates are kind of inert reactively, it could be used as hydrocarbin additives, lubricants and much more.
Completing the Sentences;
1. Carbon
2. insulating
3. Good lubricant and electrically conductive
Explanation:
SiO2 has a peculiar nature. It isn't very reactive. It has a very high melting point. grinding wheels. It is difficult to deform or melt it and its related compounds because its polar covalent (Si–C or Si–O) bonds must be broken, and this requires a large input of energy. It also does not contain any hydrogen, thus it cannot act as a Brønsted–Lowry acid. While not soluble in water, it dissloves in hot concentrated alkali or fused hydroxide.
Silicon metal is made from the reaction of silica (silicon dioxide, SiO2) and carbon materials like coke, coal and wood chips. Silica is typically received in the form of metallurgical grade gravel.
Silicates can be used as solid lubricants, lubricant additives in engine oil, as fume silica grease, rubber materials, waterproofing materials, and caulks.
Fused Silica has extremely good dielectric and insulating properties. For these reasons it is used as an inert, low expansion filler material for epoxy resins in electronic circuits as an insulator.
Answer:
<h3>The answer is 9.0 kg/L</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 1.8 kg
volume = 0.2 L
We have
We have the final answer as
<h3>9.0 kg/L</h3>
Hope this helps you
