Answer:
2
Explanation:
Data:
[H⁺] = 0.01 mol·L⁻¹
Calculation:
pH = -log[H₃O⁺] = -log(0.01) = -log(1) - log(10⁻²) = -0 - (-2) = 0 + 2 = 2
Answer:
A reaction that combines simpler reactants to form a new compound is called a
<h2>Synthesis reaction.</h2>
Answer:
P=681.07mmHg
Explanation:
gas law:
(V1 * P1 ) / T1 = (V2 * P2 ) / T2
⇒ P2 = ( V1 * P1 * T2) / ( T1 * V2)
∴ V1 = 4.6L;
P1 = 365mmHg * 0.001315 atm / 1 mmHg = 0.48 atm
T2 = 36°C + 273 = 309 K
T1 = 20 °C + 273 = 293 K
V2 = 2.6 L
⇒ P2 = ((4.6 L) * (0.48 atm) * (309 K)) / ((293 K) * (2.6 L))
⇒P2 = 0.895 atm ( 681.07 mmHg)
when compressing the gas inside the cylinder, the internal pressure increases
Radiation. I know this and I'm sorry wish I could've seen this question yesterday.
Radon decays by alpha decay and forms Polonium-218.
