Huh ion speak that language:/
Answer:
<em>The mass of NaHCO₃ that the man would need to ingest to neutralize this much HCl is 0.059 g.</em>
<em />
Explanation:
1) <u>Chemical equation (given)</u>:
- HCl (aq) + NaHCO₃ (aq) → NaCl (aq) + H₂O (l) + CO₂ (g)
Both sides have the same number of atoms of each element:
Element Let side Right side
H 1 + 1 = 2 1 × 2 = 2
Cl 1 1
Na 1 1
C 1 1
O 3 1 + 2 = 3
Hence, the equation is balanced.
2. <u>Mole ratios:</u>
<u />
- 1 mol HCl : 1 mol NaHCO₃ : 1 mol NaCl : 1 mol H₂O : 1 mol CO₂
2)<u> Determine the number of moles of HCl in solution</u>:
- M = n / V (liters) ⇒ n = M × V (liters)
- V (liters) = 200.mL (1 liter / 1000 mL) = 0.200 liter
- n = 0.035 M × 0.200 liter = 0.00070 mol of HCl
3) <u>Set a proportion with the stoichiometric ratio and the actual ratio</u>:
- 1 mol NaHCO₃ / 1 mol HCl = x / 00070 mol HCl
⇒ x = 0.00070 mol NaHCO₃
4.<u> Convert 0.0070 mol NaHCO₃ to grams</u>:
- Mass in grams = molecular mass × number of moles
- molecular mass NaHCO₃ = 84.007 g/mol
- Mass of NaHCO₃ = 84.007 g/mol × 0.00070 mol = 0.0588 g ≈ 0.059 g
The answer has two significant digits because the molarity (0.035 M) is reported with two signficant digits.
Answer:
No
Explanation:
In my opinion water doesn't evaporates when is spills on a fabric or a shirt someone is wearing. The fabric or cloth whatever you may call it sucks the water, making you feel your shirt wet. But as the time passes it will slowly dry due to the sun or the warmth surrounding the area the fabric is at.
OMG THERE'S SPIDER BEHIND YOU!!! jk XD lets get back to the question.....
example of omnivores would be us humans but since you said ANIMALS then :
BEARS - bears are omnivores they feed on meat like fish and plants like grass or dandelion.
RACCOONS - their omnivores too they feed on meat like rats (ew), fish, frogs..etc they also eat plants like any kind fruit, grains, nuts ( i dont think all kind tho).
so yup those are two examples :D
