Answer:

without being wordy, CARBON makes Only 4 and Always 4 bonds. If you want to count electrons & so on, go ahead, but in the end the

Primary Rule In Organic Chemistry is

Carbon makes 4 bonds. Check the OCTET RULE and so on to see if that gives you insight as to why, and a more complete answer. OK?

In the fermentation of glucose (wine making), 790 mL of CO2 gas was produced at 37 ∘C and 1.00 atm . You may want to reference (

Gennadij [26K]

<u>Answer:</u> The volume of the gas when the pressure and temperature has changed is 0.811 L

<u>Explanation:</u>

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1,V_1\text{ and }T_1$ are the initial pressure, volume and temperature of the gas

$P_2,V_2\text{ and }T_2$ are the final pressure, volume and temperature of the gas

We are given:

Conversion factor used:

1 L = 1000 mL

1 atm = 760 mmHg

$P_1=1.00atm=760mmHg\\V_1=790mL=0.790L\\T_1=37^oC=[37+273]K=310K\\P_2=695mmHg\\V_2=?L\\T_2=18^oC=[18+273]K=291K$

Putting values in above equation, we get:

$\frac{760mmHg\times 0.790L}{310K}=\frac{695mmHg\times V_2}{291K}\\\\V_2=\frac{760\times 0.790\times 291}{310\times 695}=0.811L$

Hence, the volume of the gas when the pressure and temperature has changed is 0.811 L

How much calcium hydroxide in grams is needed to produce 1.5 l of a 0.25m solution?

Vesna [10]

The mass ca(Oh)2 needed to produce 1.5 l of 0.25 solution is calculated as follows
find moles

=moles = molarity x volume

moles is therefore = 1.5 x 0.25 = 0.375 moles

mass = moles x molar mass
0.375mol x 74.09 g/mol = 27.78 grams

tyrosine kinase inhibitor binds and inhibits BTK. As a result of the experiment, you are able to elute BTK from the column, but

Sindrei [870]

Answer: It is because tyrosine kinases and BTK have similar solubilities

Explanation:

In column chromatography, components of a mixture are seperated based on their relative solubilities in two non-mixing phases.

In essence, tyrosine kinases and BTK are present in the eluate due to their similar solubility rates that arise from the similar chemical structure both possess (otherwise it would be impossible for the inhibitor meant for Tyrosine kinase to bind and also inhibits BTK)

Thus, the similar solubilities of both groups is the reason they could elute out of the column without being adsorped.

Gallium (Ga) consists of two naturally occurring isotopes with masses of 68.926 and 70.925 amu. (a) How many protons and neutron

pav-90 [236]

Answer:

$neutrons_{Ga-69}=38\\\\neutrons_{Ga-71}=40$

Explanation:

Hello!

In this case, since isotopes of the same element have the same number of protons and electrons but different atomic mass, we can compute the number of neutrons by subtracting the number of protons to the atomic mass of the isotope; thus, for Ga-69 and Ga-71 (rounded up to whole numbers), we obtain:

$neutrons_{Ga-69}=69-31=38\\\\neutrons_{Ga-71}=71-31=40$
