The answer is it has 4 electrons. If an atom is neutral than the electrons and protons will be equal.
Answer:
A
Explanation:
Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane
Answer:
The answer is Silver
Numbers of Protons in Silver: The element Silver (Symbol Ag) has the Atomic Number of 47. Any atom that contains exactly 47 protons in its nucleus is an atom of silver.

pH 3 = 10 times of pH 4 in terms of H⁺ concentration
<h3>Further explanation
</h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ion. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
So pH 3 and pH 4 have a difference in the concentration of H⁺ ion of 10¹ = 10
pH 3 = -log[10⁻³]
pH 4 = - log[10⁻⁴]
pH 3 = 10 times of pH 4 in terms of H⁺ concentration
And pH 3 is stronger in acid than pH 4
Since the question has pressure, temperature, and volume as variables, in order to arrive at an answer the combined gas law will be needed to arrive at an answer. The Combined Gas Law is a combination of Boyle's Law (pressure and volume are inversely proportional when temperature is constant) and Charle's Law (volume and temperature are proportional when pressure is constant) and is used when neither volume, pressure nor temperature is constant.
Combine Gas Law Equation: P₁V₁ ÷ T₁ = P₂V₂ ÷ T₂
The following values are what is known from the question:
the initial pressure (P₁) = 1 atm; the final pressure (P₂) is 0.5 atm,
the initial volume (V₁) = 300 mL or 0.3 L; the final volume (V₂) = 1 L
the initial temperature (T₁) = 27 °C
then we can substitute these into the equation to find the final temperature (T₂).
P₁V₁ ÷ T₁ = P₂V₂ ÷ T₂
∴ by substituting the known values,
⇒ (1 atm) (0.3 L ) ÷ (27 °C) = (0.5 atm)(1 L) ÷ T₂
⇒ T₂ = [ (0.5 atm) (1 L) (27 °C) ] ÷ (1 atm) (0.3 L )
⇒ T₂ = [13.5 atm · L · °C] ÷ [0.3 atm · L]
⇒ T₂ = 45 °C
Thus the new temperature of the gas is 45 °C.
