3. Rationality- he does not believe in superstitions and think that everything has a scientific explanation 
4. Critical Mindedness & Correct Judgement- he does not easily jump to conclusions but tries to verify his results by (if possible) repeating the experiment 
5. Intellectual Honesty- does not alter his observations and writes the correct observations he has seen 
6. Objectivity-<span> he writes accurate results

Calculate the pH of a solution that has [H3O+]=4.3 x 10^-5 M
Neko [114]

Answer:

pH = 4.4

Explanation:

pH = -log[H₃O⁺]

     = -log(4.3 × 10⁻⁵)

pH = 4.37 = 4.4

I'm actually learning this in my chemistry class right now lol. Hope this helps though. :)

Stainless steel is an alloy of iron, chromium, nickel, and manganese metals. If a 2.000 g sample contains 10.0% nickel, what is
AfilCa [17]

Answer:

200 g

Explanation:

Stainless steel is an alloy of iron, chromium, nickel, and manganese metals. A 2.000 g sample contains 10.0% nickel (mass percent), that is, there are 10.0 g of nickel every 100 g of the sample. The mass of nickel in the sample is:

2.000 g sample × (10.0 g Nickel/100 g sample) = 200 g Nickel

There are 200 grams of Nickel in the 2.000 g-sample.

A given mass of air has a volume of 6.00 L at 101 kPa. At constant temperature, the pressure is decreased to 25.0 kPa. Calculate
GenaCL600 [577]

Answer:

24.24 L

Explanation:

Boyle’s law, also called Mariotte’s law, a relation concerning the compression and expansion of a gas at constant temperature.

This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.

Real gases obey Boyle’s law at sufficiently low pressures, although the product pv generally decreases slightly at higher pressures, where the gas begins to depart from ideal behaviour.

As, PV = k

P₁ V₁ = P₂ V₂

Given P₁ = 101 KPa

V₁ = 6 L

P₂ = 25 kPa

So, V₂ = P₁ V₁ /P₂ = 101 *6/25 = 24.24 L
