Answer:
B, (logic) D (knowledge)
Explanation:
Problem solving refers to the ability to figure out an answer to a question. The question can be general, such as how to design an experiment, or it can be more specific, such as how to calculate speed (its distance divided by time). Reasoning is closely related to problem solving. When scientists reason, they use logic and knowledge to make conclusions and decisions. The processes of reasoning and problem solving are usually more educational than the answer. Figuring something out is a wonderful workout for your brain.

Answer:
hi!
Explanation:
Well, some things I would do is to know the Periodic Table font and back. Know they elements and their class and atomic number and weight. Know how many atoms make up each element and how many protons, neutrons, and elements are in each atom.
Answer:
15.75g
Explanation:
Rearrange the formula: density = mass/volume, so that mass is the subject: mass = density × volume
Now substitute (plug in) the known values into the formula:
mass = 10.5 × 1.5 ⇒ mass = 15.75g
The mass of the silver necklace is 15.75g

Boyle's law states that pressure is inversely proportional to volume of gas at constant temperature
PV = k
where P - pressure , V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting these values in the equation
1.25 atm x 0.75 L = P x 1.1 L
P = 0.85 atm
final pressure is B) 0.85 atm
