Na2CO3 + 2Cl- ⇒ 2NaCl + CO3^-2
<span>
1 mole of Na2CO3 = 106 g </span>
<span>2 moles of NaCl = 2 x 58.4
= 116.8 g
</span>Na2CO3 would increase by 116.8 / 106 = 1.10 to form 2NaCl.
<span>0.4862 g x 1.10 = 0.515 grams of NaCl.
</span>
K2CO3 + 2Cl- ⇒ 2KCl + CO3^-2
<span>1 mole of K2CO3 = 138.2 g </span>
<span>2 moles of KCl = 149.1 </span>
<span>
K2CO3 would increase by </span>149.1 /138.2 = 1.079 <span>to form 2KCl
</span>
<span> 0.4862 x 1.079 = 0.5246 g</span>
-well, we all need water as living organisms in order to live. water helps us clean our body (just like you clean yourself in a shower to clean your skin),but drinking water helps you to take a shower inside your body! (sounds weird but true XD) you get the point... here are a few things water does to our body:
- water helps helps our skin to look beautiful (you can say youthful skin) and even beauty itself.
- it trashes body waste and toxins (like i said above)
- it gives us nutrients and minerals
- it helps us to maintain out blood pressure
- it also helps to regulate our body temperature
- it transfers oxygen through the whole body
- it helps with digestion
- weigh loss
- gives you energy ( thats why when your exercising you need to drink water every 15 min XD)
-prevents from you have a stinky breath *-*
- it helps with back-pain, headaches, heart health...etc
- it helps boost your immune system
- increases your brain power
so those are what i got for you about why water is important to us :D
PH is the logarithmic measure of the concentration of hydrogen ions in solution. In an aqueous system, the lowest possible concentration of H+ ions (least acidic) is 1x 10^-14. The -log(1x10^-14) = pH of 14
Answer:
It depends on the objects mass, the gravitational pull when up or down slopes, and the height of the reference point
The number of protons would be equivalent to the number of electrons if the net charge on the atom is 0.
