1. big bang-the most accepted theory on the origin of the universe <span>
2. steady state-</span>all is the same and will always stay the same <span>
3. oscillating universe-</span>agrees with the big bang theory, but insists the universe expanded much quicker <span>
4. inflation-</span>it's like an inflating and deflating balloon that never stops
Question 9. The first one is the smallest. Anything with a negative exponent is going to be less than 1, the .00000241. The exponent tells you the number of zeroes to the right of the decimal point. Farther to right gets smaller and smaller.
Question 10. The last one is true. If the last digit is smaller than 5, drop the digit, and do not change. (If it is a 5 or larger, the digit before it would round up)
Hello!
The chemical equation for this reaction is the following:
2HCl (aq) + Ca(OH)₂(aq) → CaCl₂(aq) + H₂O(l)
To determine the grams of Calcium Chloride formed, we will need to determine the moles of each reactant and divide by the reaction coefficient to know which is the limiting reactant (the one that is in the lowest amount):
So, the limiting reactant is HCl, so we'll use the following conversion factor to determine the mass of CaCl₂ produced:
So,
173,41 grams of CaCl₂ are produced.
Have a nice day!
