To be honest, I learned this in school so I'll tell you XD
The formula of sodium oxide is Na2O
I believe it is 6ml because you do the doseage times the ml and mutiply it by 1
% error = 3.4 %
Percent error = |accepted value - experimental value|/accepted value × 100%
∴ % error = |355 mL – 343 mL|/355 mL × 100 % = |12|/355 × 100 % = 3.4 %
Answer:
Combustion reaction
Explanation:
Let's consider the following balanced equation.
CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O
This reaction is known as a combustion reaction, in which a compound reacts with oxygen to form a compound of carbon and water.
- If the product is carbon dioxide, the combustion is complete.
- If the product is carbon monoxide or carbon, the combustion is incomplete.
Option B is correct,
With increase in concentration the density of reactants increases and the system becomes more crowded, the greater the reactants will come in contact with each other and collisions occur. If collision is in proper orientation and has optimum energy then its fruitful and yields product. So, the greater the number of reactants, the greater will be the chances of collision and the greater will be the production of products per unit time and hence, greater is the rate of reaction.
