How many mL of ethanol would you
add to water to make 1750 mL of a
40.0% ethanol solution (v/v%)?

Answers

Answer 1

Answer:

700 mL of ethanol would be added

Explanation:

Given data:

Volume of ethanol added to make 40% v/v solution = ?

Total volume of solution = 1750 mL

Solution:

We will calculate the 40% 1750 mL which will be the volume of ethanol added to the water to make 40%v/v solution.

(40/100)× 1750 mL

0.4 × 1750 mL

700 mL

700 mL of ethanol would be added.

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?

Answers

Given:

The overall average speed = 25 cm/s.

The overall average speed increased by 10%.

To find:

The new overall average speed.

Solution:

We have,

Overall average speed = 25 cm/s.

The overall average speed increased by 10%. So, the new average speed is

New overall average speed = Initial average speed + 10% of initial  overall average speed

[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]

[tex]\text{New overall average speed}=25+2.5[/tex]

[tex]\text{New overall average speed}=27.5[/tex]

Therefore, the new overall average speed is 27.5 cm/s.

Explanation:

Seeing that the chemicals present are in question one I take it you are asking about that question.

Decreasing the concentration causes a decrease in reaction process and also the total amount of product you would get out of the given reaction

Decreasing the temperature causes the molecules in this reaction to become less excited or reactive, thus causing the reaction to slow down

how many moles of carbon are in 3.0 moles of c6h12o6

Answers

Answer:

i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

Answers

Answer:

No, It is not okay to pretend on social media.

Explanation:

No, it is not okay for people to post fake vacation pics and other fake info on social media. This is very wrong, as -

This 'all time look good, feel good, have a happening life' approach of social media - implies showing only the positive side & not negative side of people's life. However, in real life is not a bed of roses. Faking things out implies that pretending to be cool has become more important than sharing deep meaningful relationships, & highlights  superficial desire of false popularity. It is also harmful to people being communicated this fake image, as they might indulge into any social involvement, on the basis of unreal image of the concerned person.

Answers

Answer:

Climates at different latitudes are similar to one another.

Explanation:

The choice that is not a proof of Wegener's concept of concept of continental drift is that climates at different latitudes ae similar to one another.

Wegener did not use climatic evidence to proof continental drift. He did use fossils found on different continents such as the mesosaurus to propose the theory of continental drift. Wegener also used evidence of glacial sediments to justify his claims. He also fitted the earth into a giant puzzle.

Answer:

Climates at different latitudes are similar to one another.

Which of the following contains the most atoms?
24.305 g Mg
39.098 gk
21.62 g B
9.0122 g Be

Answers

Explanation:

9.0122 g be Maybe, sorry i don't think so

In the above , the sample of B 21.62 g of boron contains the most atoms because it has approximately 2 moles, while the other samples have only 1 mole each.

What is atoms

The molar mass of each element can be found on the periodic table.

The molar mass of Mg (magnesium) is about 24.305 g/mol.The molar mass of K (potassium) is about 39.098 g/mol.The molar mass of B (boron) is approximately 10.81 g/mol.The molar mass of Be (beryllium) is about  9.0122 g/mol.

To calculate the number of moles in each sample, we divide the mass of each sample by its respective molar mass:

For Mg: Number of moles = 24.305 g / 24.305 g/mol = 1 moleFor K: Number of moles = 39.098 g / 39.098 g/mol = 1 moleFor B: Number of moles = 21.62 g / 10.81 g/mol ≈ 2 molesFor Be: Number of moles = 9.0122 g / 9.0122 g/mol = 1 mole

Therefore, the sample with 21.62 g of boron (B) contains the most atom
