Answer: The correct answer is Option 4.

Explanation:

There are three sub-atomic particles present in an atom. They are: electrons, protons and neutrons.

Protons constitute in each and every atom.

The charge on proton is of equal magnitude as that of electron but having opposite sign. Proton carry a positive charge and electron carry a negative charge.

Protons and neutrons, both determine the mass of an atom.

Mass of 1 proton = 1.007276 u

Mass of 1 neutron = 1.008664 u

Mass of 1 electron = 0.00054858 u

Mass of proton is almost same as that of neutron but is more than the mass of electron.

Hence, the correct answer is Option 4.

how many moles of oxygen are needed to burn 1.33 moles of methyl alcohol (ch3oh)?2ch3oh 3o2 2co2 4h2o

dlinn [17]

2 CH3OH + 3 O2 = 2 CO2 + 4 H2O

2 moles CH3OH ---------------- 3 moles O2
1.33 moles CH3OH ----------- ( moles O2)

moles O2 = 1.33 x 3 / 2

moles O2 = 3.99 / 2

= 1.995 moles of O2

Ba(oh)2 is a strong electrolyte. determine the concentration of each of the individual ions in a 0.750 m ba(oh)2 solution.

Sindrei [870]

The concentration of each of the individual ions in a 0750 M Ba(OH)2 solution is

[Ba2+] = 0.750 M

[OH-]= 1.50 M

<h3>calculation</h3>

write the equation for dissociation

that is Ba(OH)2 (s)→ Ba2+(aq) + 2OH-(aq)

by use of mole ratio of Ba(OH)2 : Ba2+ which is 1: 1 the concentration of Ba2+ is therefore= 0.750M

by use of mole ratio of Ba(OH)2 : OH- which is 1:2 the concentration of OH- =0.750 M x2/1=1.50 M

The pressure of a tire is 200 kPa as it is pulled out from the garage on a summer

snow_tiger [21]

Explanation:

Gay-Lussac's law states that if P=pressure and T=temperature, then P/T=P/T. Temperature must be in Kelvin, but pressure can be in any unit.

To convert Celsius into Kelvin, just add 273: 10+273=283K, and 28+273=301K.

So using the equation,

200kPa÷283=? kPa÷301

Solving this equation gives you about 212.72 kPa.
