Answer:

- Rosalind Franklin

- Notting Hill, London, United Kingdom

- July 25 1920

- Rosalind Franklin made a crucial contribution to the discovery of the double helix structure of DNA, but some would say she got a raw deal. Biographer Brenda Maddox called her the "Dark Lady of DNA," based on a once disparaging reference to Franklin by one of her coworkers.

- 1953

- that today's researchers are able to use tools such as DNA sequencing and X-ray crystallography to investigate viruses such as SARS-CoV-2. Franklin's research career began in the physical sciences.

A non-mechanical, rigid, and fully insulated mixing tank is used to combine two inflows to produce wet steam. One inflow consist

Bogdan [553]

Explanation:

As it is given that stream A is super heated. From stream tables, we get that specific enthalpy, ( $h_{A}$ ) is 3054.29 kJ/kg.

For stream B, it is saturated water at 25 degree celsius. It's $h_{B}$ is 2546.54 kJ/kg.

Stream C, data will be as follows.

P = 200 kPa, $\chi$ = 0.9

So, $h_{c}$ = $h_{f} + \chi \times h_{fg}$

= 504.47 + 0.9 \times 2201.7

= 2486 kJ/kg

Now, energy balance formula will be as follows.

$m_{A}h_{A} + m_{B}h_{B}$ = $(m_{A} + m_{B})h_{c}$

$3 \times 3054.29 + m_{B} \times 2546.54$ = $(3 + m_{B}) \times 2486$

$m_{B}$ = 28.16 kg/s

Hence, inflow of saturated liquid is 28.16 kg/s. According to steam table, temperature of wet steam is $120.23^{o}C$

Mass flow rate of out flow is 31.16 kg/s.

Minchanka [31]

Answer:
Substance A is a Giant covalent structure with covalent bonding

Explanation:
Substance A is a Giant covalent structure. There are strong covalent bonds between the atoms and a large amount of heat energy is needed to break the bonds resulting in high melting point. Substance A does not conduct electricity in molten state reason being, it exist as molecules which are electrically neutral and there are no mobile charged carriers.

Hope this helps!

What is 0.0135 moles of in AlCl3 grams? Round to 3 sig figs

Mekhanik [1.2K]

Answer: 1.80g

Explanation:

Molar Mass of AlCl3 = 27 + (3x35.5)

= 27 + 106.5 = 133.5g/mol

Number of mole of AlCl3 = 0.0135mol

Mass = 0.0135 x 133.5= 1.80g
