The incrasing order (lowest first) for the values of e/m for electron, proton,neutron and alpha particle is

Chemistry
1 answer:
mina [271]3 years ago
5 0

Answer:

e/m  for electron is 1/0 (as electron has negligible mass),

for proton is 1/1,

for neutron is 0/1, and for alpha particle is 2/4 or 1/2. (Note that charge unit for e is −1, for proton is +1, for neutron is 0, )

and for alpha particle is +2. The mass unit (amu) for e is almost 0, fro p is 1, for neutron is 1, and for alpha particles is 4.

Hope it helps you!

A shiny block weighs 34.567 g and measures 3.5 cm in length, 2.0 cm in width, and 1.5 cm in thickness. What is it’s volume and d
hoa [83]
Density of a substance is given by dividing its mass with volume.
The volume of the block is 3.5 cm× 2.0 cm ×1.5 cm = 10.5 cm³
thus density = 34.56 g/ 10.5 cm³
                    = 3.291 g/cm³

This is a reaction going on in your muscle cells right this very minute:The enzyme triose phosphate isomerase catalyzes this rea
Arisa [49]

Explanation:

The given reaction is as follows.

       E + S \rightleftharpoons ES \xrightarrow[]{k_{2}} E + P

Here, [E] = triose phosphate isomerase = 0.1 nm = 0.1 \times 10^{-9}m

         [S] = Dihydroxy acetone phosphate = 5 \mu m = 5 \times 10^{-6}m

         [P] = Glyceraldehyde-3-phosphate = 2 \mu m = 2 \times 10^{-6}m

Therefore, velocity of the reaction will be as follows.

          v = \frac{d[P]}{dt} = \frac{K_{2}[E][S]}{K_{M} + [S]}

where, K_{M} = Michaelic menten constant = \frac{K_{1} + K_{2}}{K_{1}}

            v = \frac{900 \times 0.1 \times 10^{-9}m \times 5 \times 10^{-6}m}{10^{-5} + 5 \times 10^{-6}}

               = 30 \times 10^{-9} m

or,            = 30 nm/s

Hence, we can conclude that the actual velocity of the forward reaction under physiologic conditions if KM = 10 μM is 30 nm/s.

Equal volumes of H2 and O2 are placed in a balloon and then ignited. Assuming that the reaction goes to completion, which gas wi
Sonbull [250]

Answer: Oxygen

Explanation:

2H_2+O_2\rightarrow 2H_2O

As seen from the balanced equation:

2 moles of hydrogen combine with 1 mole of oxygen or 1 mole of hydrogen combine with 1/2 mole of oxygen.

According to Avogadro's law, equal volumes of gases contain equal number of molecules and hence equal number of moles.

Thus if x moles of both gases are present, x moles of hydrogen will combine with \frac{x}{2} moles of oxygen and  x-\frac{x}{2}=\frac{x}{2} moles of oxygen will be left used and will be in excess.
