explain why samples of gold and copper can have the same extensive properties, but not the same intensive properties

vivado [14]

Extensive properties, as volume and mass, depend on the amount of material. So, you can have a sample of gold and a sample of copper with the same volume as long as you have different amount of each one.

On the other hand, intensive properties do not depend on the amound of material but on the chemical constitution of the material. Density is an intensive property, so gold and copper have different densities. That is why you can use intensive properties to characterize different materials.

How to solve this: a small dog has consumed a dangerous amount of apap. the vet has ordered: rx acetylcysteine 150mg/kg/stat. yo

Fantom [35]

Given:
Stock dose/concentration of 20% Acetylcysteine (200 mg/mL)
150 mg/kg dose of Acetylcysteine
Weight of the dog is 13.2 lb

First we must convert 13.2 lb to kg:
13.2 lb/(2.2kg/lb) = 6 kg

Then we must calculate the dose:
(150 mg/kg)(6kg) = 900 mg

Lastly, we must calculate the dose in liquid form to be administered:
(900 mg)/(200 mg/mL) = 4.5 mL

Therefore, 4.5 mL of 20% Acetylcysteine should be given.

2. Problem: Is colored or black and white text more easily remembered? Hypothesis: If the text is colored, then the text is more

Varvara68 [4.7K]

Answer:

This question contains a lot of subsections. Please find the variables to each question below

Explanation:

Hypothesis is a testable explanation to a scientific question. It aims at proffering a testable solution to an observed problem. It usually goes in an IF, THEN format.

Dependent variable is the variable being measured in an experiment, while the independent variable is the variable that is manipulated or changed by the experimenter.

The control group is the group that does not receive the experimental treatment while constant is the variable that is kept unchanged for all groups in the experiment.

Based on this explanation, find the answers to the hypothesis, independent variable, dependent variable, constant, and control groups to each question.

2. Dependent variable: How easy it is to remember

Independent variable: Color of the text

Control: Group given Black and White text to read

Constants: Same text

3. Hypothesis: If the temperature is increased, THEN the speed of ants increases or move faster

Independent variable: TEMPERATURE

Dependent variable: SPEED OF ANTS

Control: Ants placed in room temperature

Constants: SAME KIND OF ANTS

4. Hypothesis: IF the pH of the soil is acidic or alkaline, THEN the growth of strawberries will be inhibited

Independent variable: pH of soil

Dependent variable: Growth of strawberries

Control: Strawberries grown in a Neutral pH soil

Constants: Same type of plants (strawberries)

5. Hypothesis: IF caffeine is taken, then the blood pressure will be increased or raised.

Independent variable: CAFFEINE

Dependent variable: BLOOD PRESSURE

Control: Group given no caffeine

Constants: Same amount of caffeine

6. Hypothesis: IF music is played, THEN the heart rate increases

Independent variable: MUSIC

Dependent variable: HEART RATE

Control: Groups placed where no music is played

Constants: Same type of music, same time music runs for etc.

7. Hypothesis: IF bleach is present/used, THEN bacteria will die

Independent variable: Bleach

Dependent variable: Death of bacteria
