Answer:
temperate, hot, degradation, California
Explanation:
Answer:
a. very acidic
Explanation:
A solution with a pH of 1.6 would be described as a very acidic solution.
The pH scale is a convenient scale for expressing the level of acidity or alkalinity of aqueous solutions.
The scale ranges from 1 to 14 in which case 1 is the lower limit and 14 the upper limit.
- An acidic solution has a pH value less than 7. As pH decreases, the acidity of the solution increases.
- Neutral solutions have a pH of 7
- An alkaline solution has a pH greater than 7 and the level of alkalinity increases as pH increases.
an acid is an ionic compound that produces positive hydrogen ions when dissolved in water and a bacis is an ionic compound that produces negative hydroxide ions when dissolved in water
<span>The mass of 1.73 moles CaH2 is 72.82 grams. The molar mass of CaH2 is 42.08 g/mol. This means that there are 42.09 grams in 1 mol. So, x grams will be in 1.73 mol of CaH2. Let's make a proportion: 42.09 g : 1 mol = x : 1.73 mol. x = 42.09 g * 1.73 mol : 1 mol. x = 72.82 g.</span>
