160 g of SO3 are needed to make 400 g of 49% H2SO4.

<h3>How many grams of SO3 are required to prepare 400 g of 49% H2SO4?</h3>

The equation of the reaction for the formation of H2SO4 from SO3 is given below as follows:

$SO_{3} + H_{2}O \rightarrow H_{2}SO_{4}$

1 mole of SO3 produces 1 mole of H2SO4

Molar mass of SO3 = 80 g/mol

Molar mass of H2SO4 = 98 g/mol

80 g of SO3 are required to produce 98 og 100%H2SO4

mass of SO3 required to produce 400 g of 100 %H2SO4 = 80/98 × 400 = 326.5 g of SO3

Mass of SO3 required to produce 49% of 400 g H2SO4 = 326.5 × 49% = 160 g

Therefore, 160 g of SO3 are needed to make 400 g of 49% H2SO4.

How does an atom end up with an octet, if it loses all of the electrons in its valence shell

tamaranim1 [39]

Answer:

When atoms have fewer than eight electrons, they have an inclination to react and type a lot of stable compounds.

Thus, associate atom continues to create bonds till associate octet of electrons is formed. this can be called octet rule by Lewis.

Which are advantages of using a reflecting telescope instead of a refracting telescope? Check all that apply. Reflecting telesco

slega [8]

The answers are:
Reflecting telescopes are less expensive, the materials are not costly.

Reflecting telescopes can gather light from objects. This becomes basis the system to see Celestial objects.

Reflecting telescopes uses mirrors and Refracting telescopes use lenses. It is also much bigger in size because of the mirrors placed inside.

How do you determine the number of electrons an atom will gain or loose

enyata [817]

In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion. Hydrogen is an exception, as it will usually lose its electron. Metalloids and some metals can be can lose or gain electrons. This is not always true, as elements such as nitrogen can lose electrons to become positive. When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons. Hope this helps :)
