What chemicals are mixed when making fire?
When potassium chlorate and ordinary table sugar are combined, and a drop of sulfuric acid is added as a catalyst, the two react violently with each other, releasing large quantities of heat energy, a spectacular purplish flame, and a great deal of smoke.
Can you describe the solutions that are being mixed?
Solutions are homogenous mixtures: particles of one substance (the solute) are mixed together with the particles of another substance (the solvent) – eg salty water. Heterogeneous mixtures: large aggregations (clumps) of the substances are mixed together – eg emulsions like oil in water.
What are the potential dangers of mixing chemicals?
Dangers of Mixing Household Chemical Cleaners
- Bleach + Vinegar = Chlorine gas. This can lead to coughing, breathing problems, burning and watery eyes.
- Bleach + Ammonia = Chloramine. This can cause shortness of breath and chest pain.
- Bleach + Rubbing alcohol = Chloroform. Another highly toxic combination!!
- Hydrogen peroxide + Vinegar = peracetic/ peroxyacetic acid.
What formed when two or more substances are combined?
Two or more elements combined into one substance through a chemical reaction form a chemical compound. All compounds are substances, but not all substances are compounds. A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice.
When the dry ingredients of a cake are combined what is the result?
Dry ingredients are combined in one mixing bowl and the liquid ingredients are added. After mixing, the dry ingredients and fat, the eggs, and the remaining liquid ingredients are added. The fat coats the flour, helping to produce a “melt-in-your-mouth” cake or a more open and less fine texture than a creamed cake.
What goes first dry or wet ingredients?
BUT whether you are making cookies, muffins, cake, or pancakes, the general rule of baking is that dry ingredients should be combined together thoroughly in one bowl BEFORE you add the wet ingredients.
What causes a cake to rise?
Leaveners, like baking soda or powder, produce carbon dioxide bubbles, which are trapped by the starch in the batter and expand during baking, causing the cake to rise.
