If the approximate density of 6.5 L of ethanol is 0.79 g/ mL, what is the mass in grams?

Answers

Answer:

The answer is 5135 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 0.79 g/mL

1 L = 1000 mL

6.5 L = 6500 mL

We have

mass = 0.79 × 6500

We have the final answer as

5135 g

You have decided to bake a cake. You mix all of your ingredients together to make a delicious chocolate cake. Then, you bake your cake at 350 degrees fahrenheit. You have to perform both a physical and a chemical change to bake a cake. What is the chemical change? Include at least 2 pieces of evidence or indicators to explain how you know it was a chemical change.

Answers

Answer:

A gas is evolved

The ingredients can not be recovered

Explanation:

A chemical change is one in which a new substance is formed and it is not easily reversible.

One major ingredient used in cake baking is the baking powder or baking soda.

Baking a cake can be viewed as a chemical change. This is because, when the baking powder or soda is added in the presence of yeast, carbon dioxide gas is evolved as tiny bubbles of gas which makes the cake light and fluffy. Heat is equally given off in the process. The baking powder and other cake ingredients can not be recovered, hence, we can conclusively assert that a chemical change has taken place.

In what way is kinetic energy present in a solar oven

Answers

Answer:

Energy of motion is called

8.3 kg, 1.7 Kg/cm3
-> ? cm3

Answers

Answer:

4.9 cm³

Explanation:

Given data:

Mass value = 8.3 kg

Density = 1.7 kg/cm³

Volume = ?

Solution;

In given question from the units we got to know that the mass and density value is given and we have to calculate the volume.

Thus, we will apply density formula.

Density = mass/ volume

d = m/v

1.7 kg/cm³ = 8.3 kg/ v

v =  8.3 kg/ 1.7 kg/cm³

v = 4.9 cm³

Thus, the volume is 4.9 cm³.

Find the speed of the ATV that goes 60 miles in 2 hours._______________________ m/hr

Answers

Given parameters:

Distance of ATV  = 60miles

Time = 2hrs

Unknown:

Speed  = ?

Solution:

Speed is a scalar quantity. It has magnitude but no direction. Mathematically, speed is distance divided by time.

                      Speed  = [tex]\frac{distance}{time}[/tex]

 Input the parameters;

              Speed  = [tex]\frac{60}{2}[/tex]  = 30miles/hr

How many atoms are in 0.075 mol of titanium?

O 4.5 x 1022
O 1.2 x 10-25
O 6.4 x 102
O 2.2 x 1024

Answers

Answer:

The answer is

4.5 × 10²²

Explanation:

To find the number of atoms of titanium , given it's number of moles we use the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

n = 0.075 mol

We have

N = 0.075 × 6.02 × 10²³

We have the final answer as

4.5 × 10²²

Alfred Wegener suggested that earths continents are moving. Which evidence supports this theory? Why did Spanish officials send an expedition led by Alonso de Leon to Texas in 1698? ey's Bell Jar...AbstractBackgroundPhotosynthesis maintains aerobic life on Earth, and Joseph Priestly firstdemonstrated this in his eighteenth-century bell jar experiments using mice andmint plants. In order to demonstrate the fragility of life on Earth, Priestley'sexperiment was recreated using a human subject placed within a modern-daybell jar.MethodsA single male subject was placed within a sealed, oxygen-depleted enclosure(12.4% oxygen), which contained 274 Cz and C plants for a total of 48 h. Acombination of natural and artificial light was used to ensure continuousphotosynthesis during the experiment. Atmospheric gas composition within theenclosure was recorded throughout the study, and physiological responses in thesubject were monitored.ResultsAfter 48 h, the oxygen concentration within the container had risen to 18.196, andhypoxaemia in the subject was alleviated (arterial oxygen saturation rose from86% at commencement of the experiment to 99% at its end). The concentrationof carbon dioxide rose to a maximum of 0.66% during the experiment.ConclusionsThis simple but unique experiment highlights the importance of plant life withinthe Earth's ecosystem by demonstrating our dependence upon it to restore andsustain an oxygen concentration that supports aerobic metabolism. Without thepresence of plants within the sealed enclosure, the concentration of oxygenwould have fallen, and carbon dioxide concentration would have risen to a pointat which human life could no longer be supported.
