How can exposoure to high energy waves be both harmful and helpful to cells??

1 answer:

3 0

Exposure to high energy waves can be helpful to cells by damaging DNA in cells, meaning if somebody were to have cancer cells it breaks down the bad cells and it can shrink tumor. It can be harmful by damaging skin cells, which we need as our first line of defense. Meaning, it could cause skin cancer. Hope this helped!

How many moles of nitrogen gas are in a flask with a volume of 0.25 L at a pressure of 2.96 atm and a temperature of 300 K

aniked [119]

<u>Answer:</u> The number of moles of nitrogen gas is 0.030 moles

<u>Explanation:</u>

To calculate the number of moles of nitrogen, we use the equation given by ideal gas which follows:

$PV=nRT$

where,

P = pressure of the nitrogen gas = 2.96 atm

V = Volume of the gas = 0.25 L

T = Temperature of the gas = 300 K

R = Gas constant = $0.0821\text{ L. atm }mol^{-1}K^{-1}$

n = number of moles of nitrogen gas = ?

Putting values in above equation, we get:

$2.96atm\times 0.25L=n\times 0.0821\text{ L. atm }mol^{-1}K^{-1}\times 300K\\\\n=\frac{2.96\times 0.25}{0.0821\times 300}=0.030mol$

Hence, the number of moles of nitrogen gas is 0.030 moles

Give the major product formed when phenol is heated with concentrated H2SO4 and SO3. (There is more than one correct answer, but

iris [78.8K]

Answer:

See image attached and explanation

Explanation:

The reaction of phenol with SO3/H2SO4 is an electrophilic reaction. The electrophile attacks portions of high electron density in the substrate phenol.

The -OH group activates phenol towards electrophilic substitution at the ortho and para positions, hence the product(s) formed in this reaction(only one product is shown here as required by the question).

The sulphonation of phenol using concentrated sulfuric acid at lower temperature yields majorly the ortho product whereas at higher temperature the para product predominates.

4.) The temperature of solid silver increases from 30C to 40C by the addition of 117.5

Artyom0805 [142]

Answer:

The mass of silver is 49 g (0.049 kg).

Explanation:

Initial temperature = $30^{o}$ C

Final temperature = $40^{o}$ C

Quantity of heat required = 117.5 J

Specific heat capacity of silver = 0.240 J/g $^{o} C$

mass of the silver can be determined by;

Q = mcΔθ

Where: Q is the quantity of heat required, m is the mass of substance, c is the specific heat capacity of the substance and Δθ is the change in temperature.

So that,

117.5 = m x 0.240 x (40 - 30)

117.5 = m x 0.24 x 10

= 2.4m

m = $\frac{117.5}{2.4}$

= 48.9583

m ≅

m = 49 g

The mass of silver is 49 g (0.049 kg).
