cis-2- butene-1,4-dioic acid and trans-2- butene-1,4-dioic acid are the 2 isomers with the molecular formula C₄H₄O₄.

<u>Explanation:</u>

Isomers are the structures having the same molecular formula but their is a difference in their structural formula and this concept is known as isomerism.

Here we have the molecular formula C₄H₄O₄ and it may be dicarboxylic acid and it may be exist as geometrical isomers as cis-2- butene-1,4-dioic acid and trans-2- butene-1,4-dioic acid.

The isomers are given.

A perfect cube of aluminum metal was found to weigh 20.00 g. The density of aluminum is 2.7 g/ml. What are the dimensions of the

denis23 [38]

Answer:

Height = 1.9493 cm

Width = 1.9493 cm

Depth = 1.9493 cm

Solution:

Data Given:

Mass = 20 g

Density = 2.7 g/mL

Step 1: Calculate the Volume,

As,

Density = Mass ÷ Volume

Or,

Volume = Mass ÷ Density

Putting values,

Volume = 20 g ÷ 2.7 g/mL

Volume = 7.407 mL or 7.407 cm³

Step 2: Calculate Dimensions of the Cube:

As we know,

Volume = length × width × depth

So, we will take the cube root of 7.407 cm³ which is 1.9493 cm.

Hence,

Volume = 1.9493 cm × 1.9493 cm × 1.9493 cm

Volume = 7.407 cm³

Points)<br> Determine the molar mass of NaCl (the solute) in a 0.1M aqueous solution of NaCl

nalin [4]

Answer:

58.443 g/mol

Explanation:

The molar mass of NaCl is the sum of the molar masses of the individual atoms:

Na: 22.989770 g/mol

Cl: 35.453 g/mol

The total molar mass is ...

NaCl: 58.443 g/mol

The molar mass does not depend on whether the material is in solution or in any other form.

Westkost [7]

Answer:

HIIT workouts are anaerobic, and cardiovascular endurance workouts are usually aerobic, depending on how much you work out. If you changed speed and switched to a different workout immediately after what you did before, your heart rate would increase, and you would experience pain on the side of your abdominal. It can be because your body isn’t used to the change in speed and endurance.
