Answer:
The answer to your question is given below
Explanation:
From the question given above, the following data were obtained:
Concentration (g/mL) = 0.04 g/mL
Concentration (g/L) =?
We can convert g/mL to g/L by doing the following:
1 g/mL = 1000 g/L
Therefore,
0.04 g/mL = 0.04 g/mL × 1000 g/L / 1 g/mL
0.04 g/mL = 40 g/L
0.04 g/mL is equivalent to 40 g/L.
Thus, the concentration (g/L) is 40 g/L
Answer:
The correct option is;
True
Explanation:
Combustion is a chemical reaction between components of a combustion reaction which are;
1) A fuel
2) An oxidizing agent
The oxidizing agent or oxidant in a combustion reaction consist mainly of oxygen.
A combustion reaction is an oxidation and reduction (redox) heat evolving (exothermic) reaction that takes place at high temperatures and produces smoke which consists of gaseous mixture of chemicals and sometimes very small solid particles
An exothermic reaction can be classed either as rapid, spontaneous, or explosive
A spontaneous exothermic reaction is one that begins on its own in atmospheric conditions and room temperature as the heat required to begin the reaction is produced by the initial oxidation of the reacting fuel
Example of a substance that undergoes spontaneous oxidation reaction is white phosphorus.
