Chem I CP BALANCING CHEMICAL EQUATIONS
INSTRUCTIONS:
For each word equation write a balanced chemical formula equation.
1. Solutions of potassium hydroxide and aluminum nitrate were mixed together yielding a
white ppt and a soluble salt.
2. Drinking alcohol, ethanol (CH3CH2OH), burns completely in oxygen gas to give two prod-
ucts only: water vapor and carbon dioxide gas.
3. Aqueous chlorine reacts with a solution of sodium iodide to give sodium chloride and ele-
mental iodine in solution.
4. Solutions of phosphoric acid and calcium hydroxide neutralize each other. A white ppt is
observed.
5. HgO solid (mercuric oxide) when heated breaks down into its elements.
6. Sodium metal reacts with oxygen gas to give sodium oxide.
7 Debrecitim carbonate crystals react with hydrochloric acid to give water and a gas that

43.452

step-by-step explanation:

284 times .153 = 43.452

the dependant variable is spilled water

the independent is the heat

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock
