Help needed urgentlythe word missing or partially seen is oxygen ​ I forgot to put more pointa

Chemistry
1 answer:
butalik [34]3 years ago
4 0

Explanation:

2.04 % hydrogen

32.65% sulphur

65.31% is oxygen

atomic ratio

hydrogen =2.04÷1=2.04

sulphur =32.65÷32=1.02

oxygen =65.31÷16=4.08

simplest ratio

hydrogen = 2.04÷1.02=2

sulphur =1.02÷1.02=1

oxygen =4.08÷1.02=4

empirical formula is H2SO4

Which of the following steps correctly converts 1.25 moles of fluorine to an equivalent mass of fluorine in grams? (5 points)
steposvetlana [31]

Explanation:

Given the amount of fluorine is ---- 1.25 mol.

What is the mass of given fluorine in grams?

Since

Number of moles =\frac{given mass of the substance}{its molecular mass}

To get the mass of the substance in grams, multiply the given number of moles with the molecular mass of the substance.

Hence, among the given options, the correct answer is the last option that is

Multiply the atomic mass of fluorine by 1.25.

An ionized helium atom has a mass of 6.6 × 10-27 kg and a speed of 5.3 × 105 m/s. It moves perpendicular to a 0.78-T magnetic fi
arsen [322]

Explanation:

In a magnetic field, the radius of the charged particle is as follows.

             r = \frac{mv}{qB}

where,   m = mass,      v = velocity

              q = charge,    B = magnetic field

Therefore, q will be calculated as follows.

         q = \frac{mv}{rB}

            = \frac{6.6 \times 10^{-27} \times 5.3 \times 10^{5}}{0.014 m \times 0.78 T}

            = \frac{34.98 \times 10^{-22}}{0.01092}

            = 3.2 \times 10^{-19} \times \frac{1.0 e}{1.6 \times 10^{-19}C}

            = +2e

Thus, we can conclude that the charge of the ionized atom is +2e.
