One of the uses of methanol (CH3OH) in dilute form is as a windshield washer antifreeze. In pure form, methanol has a molar concentration of 24.7M. How many moles are contained in 500 mL of solution?

Answers

Mol of methanol =12.35Further explanation

Mole itself is the number of particles contained in a substance

1 mole = 6.02.10²³ particles

Mole : the ratio of the amount of substance mass and its molar mass

[tex]\large{\boxed{\boxed{\bold{mole=\frac{mass}{molar\:mass}}}}[/tex]

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Molar concentration of methanol=24.7 M

Volume of solution = 500 ml = 0.5 L

[tex]\tt mol=M\times V\\\\mol=24.7\times 0.5\\\\mol=12.35[/tex]

Ben makes five paper helicopters with different wing lengths. He drops them the same way from a height of two meters for five trials each. He records the amount of time it takes for each helicopter to fall to the ground. What is the independent variable?

Answers

Answer:

Wing length

Explanation:

According to the given excerpt, independent variable is 'wing length' and dependent variable is 'amount of time it takes for helicopter to hit the floor'.

Independent variable refers to the variable that do not undergo any change or shift in the course of the experiment of research. The other variables are measured using the constant independent variable. The value obtained from the independent variable is independent. On the other and, the dependent variable witnesses change with respect to the independent variable.

Incorrect answer C A plant cell must contain chlorophyll, but can have no nucleus. Incorrect answer D A plant cell has neither a nucleus nor chlorophyll.

Answers

Answer:

B A plant cell can contain both chlorophyll and a nucleus.

Explanation:

All plants are eukaryotic organisms i.e the cells of all plants possess a membrane-bound nucleus that houses their genetic material (DNA). In addition to this, most plant cells also contain a unique organelle called CHLOROPLAST, which they use to capture the energy from sunlight in order to perform a process called PHOTOSYNTHESIS.

According to this question, plant cells can contain both chlorophyll and a nucleus. They can possess chlorophyll because chlorophyll is a pigment in their chloroplast that captures the light energy.

Explanation:

When copper is bombarded with high-energy electrons, X rays are emitted. Calculate the energy (in joules) associated with the photons if the wavelength of the X rays is 0.154 nm.

Answers

Answer:

E = 12.92 × 10^(-16) J

Explanation:

Formula for energy is;

E = hc/λ

Where;

h is Planck's constant = 6.63 x 10^(-34) J.s

c is speed of light = 3 × 10^(8) m/s

λ is wavelength = 0.154 nm = 0.154 × 10^(-9) m

E = (6.63 x 10^(-34) × 3 × 10^(8))/(0.154 × 10^(-9))

E = 12.92 × 10^(-16) J

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

When copper is bombarded with high-energy electrons, X rays, with a wavelength of 0.154 nm (λ) are emitted.

We can calculate the energy (E) associated with the photons of these X rays using the Planck-Einstein relation.

[tex]E = \frac{h \times c }{\lambda } = \frac{(6.63 \times 10^{-34}J.s ) \times (3.00 \times 10^{8}m/s ) }{0.154 \times 10^{-9} m } ]= 1.29 \times 10^{-15} J[/tex]

where,

h: Planck's constantc: speed of light

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

Matter is anything that takes up space and can be described by physical and chemical properties. Which statement
BEST differentiates chemical properties from physical properties?
A)
Physical properties are properties that can be physically seen or touched,
while chemical properties can only be found when matter is mixed with
specific chemicals.
B)
Physical properties are measured when matter changes its physical state,
while chemical properties can only be measured if matter remains in one
state for an extended time.
C)
Physical properties are difficult to measure because they require special
tools to detect, and chemical properties are easy to measure and require
not special tools to detect.
D)
Physical properties can be measured/observed without changing matter
into something else, while chemical properties describe matter's ability to
react/combine with other matter.

Answers

Answer:

D)

Physical properties can be measured/observed without changing matter

into something else, while chemical properties describe matter's ability to

react/combine with other matter.

Explanation:

Physical Change                                                                                              

The changes that occur only due to change in shape or physical properties but their chemical or internal composition remain unchanged.  

1 = These changes were reversible.

2= They have same chemical property.

3= These changes can be observed with naked eye.

Example :

Water converting to Ice

Water converting to gas

In this water molecule remain the same only they rearrange themselves that change its state of mater not composition

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

1 = These changes are irreversible

2 = These changes occur due to chemical reactions

3 = These may not be observed with naked eye

Combustion of fuel or wood: that oil or wood convert into energy, CO₂ and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg .

Burning 1 kg of coal releases about 3 million joules of energy. If you could use all of the chemical energy to lift another kilogram of coal, how high could you lift it?

Answers

I could lift 3.06 x 10⁵ m high

Further explanation

Energy is the ability to do work. Energy can change from one energy to another

Potential energy is the energy that an object has because of its position

The potential energy can be formulated:

Ep = m. g. h

E = potential energy of an object, joule

m = object mass, kg

g = gravity acceleration, m / s²

h = height of an object, m

energy of coal = 3.10⁶ J

mass = 1 kg

g = 9.8 m/s²

[tex]\tt h=\dfrac{E}{m.g}\\\\h=\dfrac{3.10^6}{1\times 9.8}=3.06\times 10^5`m[/tex]

If an ion has a positive charge then it has lost an electrons.

Which is the best way to determine if an object is made of pure silver?
O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.

Answers

Answer:

The correct option is;

Determine the density of the object and compare the known density of pure Silver

Explanation:

The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)

The  density is then fond by dividing the weighed mass by the volume the object displaces when immersed

Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.
