I would predict the color to be yellow-orange because the first element in the formula, and
also the metal, is sodium and therefore would fall under the other sodium formulas that
<span>produced a yellow-orange color.</span>
Almost always oxidation,
the speed of the reaction is the big difference between fire and explosions
<span>(and slower yet - the "respiration" reactions that keep you alive).</span>
Photosynthesis is a process that uses sunlight to synthesize food from carbon dioxide and water its main goal is to convert water and carbon dioxide and its glucose which serves as food and plants and it releases oxygen using light energy from the sun
Answer: for the first question, Hypochloride is being released from your bleach to oxidize your fabric. As you know oxidation simply mean addition of oxygen, so when hypochloride (ClO-) comes in contact with fabric oxygen is added and some organic bonds are broken and the dirt is washed out.
For the second question. The melting and boiling point of pure substance is sharp. Like water has 100oC boiling point and OoC melting point. So anything from that means it has impurities in it. Just like if you make tea, you have introduce something else into the water, if you should try boiling your tea, you'll find out that the boiling point is not going to 100oC anymore. Every other liquid have their boiling point and melting point. When you know them, you'll be able to determine the purity.
The unit of 16.8 /kjg contains a mistake.
I just can help you by assuming the right units.
I will assume 16.8 kj /g. This is a rate, which means that 1 g of reactant will produce 16.8 kj of heat.
To calculate the mass of reactant that will produce 800j first you multiply by the conversion factor to obtain kj, and the you divide by the rate of heat, 16.8 kj/g
heat * conversion factor / rate
(800j) * (1kj/1000j) / (16.8 kj / g) <--- answer
