Answer:
The answer to your question is: letter B
Explanation:
Data
3.58 x 10⁴ cal to joules
1 calories --------------- 4.184 joules
3.58 x 10⁴ cal----------- x
x = ( 3.58 x 10⁴ x 4.184) / 1
x = 149787.2 joules
x = 1.5 x 10⁵ J
I think its chlorine Im not positive but im 99.9 precent shure
Answer:
Photosynthesis gas, is called carbon dioxide. Carbon Dioxide in this process is where the plants take in the dioxide and water, which is slowly reduced which gains electrons! :)

Answer:
49.95 g of HCl
Explanation:
Let's formulate the chemical equation involved in the process:
Ca(OH)2 + 2 HCl → CaCl2 + 2 H2O
This means that we need 1 mole of Calcium hydroxide to neutralize 2 moles of hydrochloric acid. From this, we calculate the quantity of HCl moles that would be neutralized by 0.685 moles of Ca(OH)2
1 mole Ca(OH)2 ---- 2 moles HCl
0.685 moles Ca(OH)2 ---- x = 1.37 moles HCl
Now that we know the quantity of HCl moles that would react, let's calculate the quantity of grams this moles represent:
1 mole of HCl ---- 36.46094 g
1.37 moles ------ x = 49.95 g of HCl
