I think the correct answer is A. Dichlorosilane has a formula of SiH2Cl2. As we can see, for every mole of this compound there will be two atoms of chlorine, two atoms of hydrogen and one atom of silicon. There are 3 different types of atoms involved. And all of this makes up a compound.

What is the pressure of a gas in torr if its pressure is 305 kPa?
FromTheMoon [43]

Answer:

the pressure of the gas in torr is 2280 torr

Explanation:

The pressure of a gas in torr can be calculated by converting its pressure in kPa to atmospheres and then converting the atmospheric pressure to torr.

One atmosphere is equal to 101.325 kPa. Therefore, the pressure of the gas in atmospheres is 305 kPa / 101.325 kPa/atm = 3.00 atm.

One torr is equal to 1/760 of an atmosphere. Therefore, the pressure of the gas in torr is 3.00 atm * 760 torr/atm = 2280 torr.

Therefore, the pressure of the gas in torr is 2280 torr

((2.0265-2.02)/2.0265) x 100.00
lianna [129]

Answer 0.5

when reporting calculations from sig figs, report the number of sig figs in the least accurate measurement

so

((2.0265-2.02)/2.0265) x 100.00

((2.0265/2.0265) - (2.02/2.03)) X 100.00

(1.0000 -0.995) X 100.00

0.005 X 100.00

0.5

Based on their electronegativities, you would expect ____ elements to pull on electrons more strongly than ______ elements.
sveta [45]

Answer:

I interpret the answers as being nonmetallic and metallic.

Explanation:

Nonmetals are in groups 14 - 18. Electronegativity is referred to as the want to attract electrons to an atom. Noble gases (group 18) have eight valence electrons in their outer subshells and are therefore atomically stable. Elements with only 7 valence electrons are very electronegative because they desire to obtain an electron to reach stability more than a group 2 element would (they are more likely to drop electrons by giving away in order to reach atomic stability of a group 18 element). This coincides with electron configuration, which is a very lengthy topic to cover. You can conduct more research if you would need it.
