Answer:
Creativity
Skepticism
Reasoning
Explanation:
Scientists must see a creative way to solve problems in the world. Scientists must also be skeptic about what is said, because if they were not, no one would disagree and the problems would never be solved. Reasoning is a must, as reasoning is involved in the scientific process and writing conclusions to their studies.
Hope this help!
Answer:
6.696 g/cm3
Explanation:
From the question;
Mass = 17.41g
Volume of water before = 46.3 cm3
Volume of water after = 48.9 cm3
Volume of antimony = Volume after - Volume before = 48.9 - 46.3 = 2.6 cm3
Density = Mass / Volume
Density = 17.41 / 2.6 = 6.696 g/cm3
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal
Answer:
The appropriate solution is:
(a) n ≈ 900
(b) n ≈ 1165
Explanation:
According to the question,
(a)
The final number of molecules throughout water will be:

where, n = number of extractions
Now,
The initial number of molecules will be:
=
=
Final number of molecule,
⇒
(b)
Final molecules of X = left (0.01%)
hence,
⇒
Answer:
2,282 cm³
Explanation:
If all other variables are being held constant, you can find the new volume of the balloon using the Charles' Law equation. The equation looks like this:
V₁ / T₁ = V₂ / T₂
In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. Before you can solve for the new volume, you need to convert Celsius to Kelvin (negative values do not work in this equation). This can be done by adding 273.15 to each temperature.
V₁ = 2600 cm³ V₂ = ? cm³
T₁ = 21 °C + 273.15 = 294.15 K T₂ = -15 °C + 273.15 = 258.15 K
V₁ / T₁ = V₂ / T₂ <----- Charles' Law
(2600 cm³) / (294.15 K) = V₂ / (258.15 K) <----- Insert values
8.839 = V₂ / (258.15 K) <----- Simplify left side
2282 = V₂ <----- Multiply both sides by 258.15
