Answer:

Carbon dioxide

Explanation:

The oxygen atoms are more electronegative than the carbon atom, so there are two individual dipoles pointing outward from the C atom to each O atom. However, since the dipoles are of equal strength and are oriented this way, they cancel out and the overall molecular polarity of CO 2 is zero.

According to Wookieepedia, Kylo Ren stands 1.89 m tall and his mass is 89 kg. Calculate his earth-weight in lbm. (2 pts) a. b. A

harina [27]

Answer:

a) 6312.12 lbm

b) D = 11.843 inch

Explanation:

GIVEN DATA:

Height of person = 1.89 m = 74.41 inch

mass of person m = 89 kg = 196.211 lbm

a) person earth weight =mg

where g is acceleration due to gravity = 32.17 ft/sec^2

$= 196.211\times 32.17 = 6312.12 lbm$

b) waist to height ratio = 0.5

$waist\ to\ height\ ratio = \frac{circumference\ of\ the\ waist}{height\ of\ the\ person}$

circumference of waist = $height\ of\ person \times waist\ to\ height ratio$

$= 74.41 inch \times 0.5$

=37.21 inch

we know that circumference is given as $= 2\pi r\ or\ \pi D= 37.21$

D = 11.843 inch

A 10.0-gram sample of which element has the smallest volume at STP?

DaniilM [7]

(4) zinc

Explanation:

Given parameters:

Mass of the sample = 10g

Condition = STP

Unknown:

Element with the least volume = ?

Solution:

The number of moles of substance as STP can be derived using the equation below;

Volume of substance = number of moles x 22.4

Number of moles = $\frac{mass}{molar mass}$

since mass = 10g

Number of moles of Al = $\frac{10}{27}$ = 0.37mole

Number of moles of Ti = $\frac{10}{47.9}$ = 0.29mole

number of moles of Mg = $\frac{10}{24}$ = 0.47mole

Number of moles of Zn = $\frac{10}{65.5}$ = 0.15mole

Zinc has the least number moles and it will have the lowest volume at STP because the volume directly proportional to number of moles.

What volume would 3.01•1023 molecules of oxygen gas occupy at STP?

Sliva [168]

First, find moles of oxygen gas: (3.01 x10^23 molec.)/(6.02 x10^23) =0.5mol O2

Second, multiply moles by the standard molar volume of a gas at STP:(0.5mol)(22.4L) = 11.2L O2
