Answer: Temperature is the independent variable and amount of sugar in the solution is the dependent variable.

Explanation:

Dependent variable is defined as the variable whose value changes with respect to any other variable.

Independent variable is defined as the variable which remain as such and has no effect on the change of another variable. For Example: Time

Solubility is a property of substance to interact with the solvent particles. Thir property is dependent on temperature.

As, the temperature of the system increases, the solubility of the substance will increase and vice-versa.

Hence, temperature is the independent variable and amount of sugar in the solution is the dependent variable.

What volume of concentrated hydrochloric acid (12.0 M HCl) is required to make 2.0 liters of a 3.0 M HCl solution?

Allushta [10]

Given:

12.0 M HCl

2.0 liters of a 3.0 M HCl

Required:

volume of concentrated hydrochloric acid

Solution:

M1V1 = M2V2

(12.0 M HCl)V1 = (3.0 M HCl)( 2.0 liters)

V1 = (3.0 M HCl)( 2.0 liters)/ (12.0 M HCl)

V1 = 0.5 liters

Based on my scale, I have 35g of aluminum. How many aluminum atoms is this? SHOW YOUR WORK.

Aleksandr-060686 [28]

One mole of a substance contains 6.02×10∧23 particles,
1 mole of a aluminium contains 27 g
35 g of aluminium contains 35/27 =1.296 moles
Thus, the number of particles will be 1.296 × 6.02 ×10∧23
= 7.804 × 10∧23 particles,
Hence, 35 g of Aluminium contains 7.804 × 10∧23 atoms

It is thought that Vitamin C might be an effective preventative

Anon25 [30]

Answer:

IF the fruit juice contains a high level of vitamin C, THEN the preventative effectiveness against common cold increases.

Explanation:

The hypothesis is a testable explanation of a scientific investigation. It aims at predicting the outcome of the experiment. One feature of the hypothesis is that it must be testable. The hypothesis is usually written in an "IF, THEN" format.

This question is regarding an experiment to test the amount of vitamin C in fruit juice. The vitamin C is thought to be an effective preventative against common cold. Hence, the hypothesis connects the effect on common cold (dependent variable) with the amount of vitamin C (independent variable). The hypothesis can be written as:

IF the fruit juice contains a high level of vitamin C, THEN the preventative effectiveness against common cold increases.

Which of the following elements is going to be the most reactive and why? Nitrogen or Oxygen?

bagirrra123 [75]

Answer:

electronegativity

Explanation:

Oxygen will be most reactive

configuration = $1s^22s^22p^4$

As oxygen need only two electrons to complete its octet.

Oxygen will have stronger force than nitrogen as it will tend to pull electrons more to complete its octet. Also along the period electronegativity increases so oxygen has higher electronegativity than nitrogen
