Answer:
Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them.
The number of atoms of gold in the pure ring are 7.18 × 10²² atoms.
<h3>HOW TO CALCULATE NUMBER OF ATOMS?</h3>
The number of atoms in a substance can be calculated by multiplying the number of moles of the substance by Avogadro's number.
The number of moles in the gold (Au) can be calculated by dividing the mass of gold by its molar mass (196.97g/mol).
no. of moles = 23.5g ÷ 196.97g/mol
no. of moles = 0.119mol
Number of atoms in Au = 0.119 × 6.02 × 10²³
no. of atoms = 7.18 × 10²² atoms.
Therefore, the number of atoms of gold in the pure ring are 7.18 × 10²² atoms.

Answer:
Consumption of Antacid
Explanation:
At breakfast when Peter ate junk food , excess acid could have got released due to which he had got acidity in his stomach. By consumption of Antacid can reduce the effect of acidity because antacid is a mild base. When a mild base reacts with acid it neutralises the effect of acid & hence gives a relief from acidity...

Answer:
380 mL is the new volume
Explanation:
At constant pressure.
V₁ / T₁ = V₂ / T₂
Temperature must be in Absolute Values (T°K = T°C + 273)
-125°C + 273 = 148 K
31°C + 273 = 304 K
185 mL / 148 K = V₂ / 304 K
V₂ = (185 mL / 148 K) . 304 K → 380 mL
