Answer:
Magnesium, Mgstart text, M, g, end text, is a group 2 element that will form 2+ cations. Because it usually forms cations of only one type, we don't need to specify its charge. We can simply refer to the cation in the ionic compound as magnesium. ... Therefore, the name for the compound is magnesium phosphide.
Explanation:
(this may or not be correct)
-also i finished that drawing you wanted :p-
The question is incomplete. the complete question is:
A chemistry student needs 35.0 g of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is
. Calculate the volume of pentane the student should pour out.Round your answer to 3 significant digits.
Answer: The volume of pentane the student should pour out is 55.9 ml
Explanation:
Density is defined as the mass contained per unit volume.
To calculate volume of a substance, we use the equation:
![\text{Density of pentane}=\frac{\text{Mass of pentane}}{\text{Volume of pentane}}](https://tex.z-dn.net/?f=%5Ctext%7BDensity%20of%20pentane%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20pentane%7D%7D%7B%5Ctext%7BVolume%20of%20pentane%7D%7D)
We are given:
Density of pentane = ![0.626g/cm^3](https://tex.z-dn.net/?f=0.626g%2Fcm%5E3)
Mass of pentane = 35.0 g
Putting values in above equation, we get:
![0.626g/cm^3=\frac{35.0g}{\text {Volume of pentane}}\\\\\text{Volume of pentane}=55.9cm^3=55.9ml](https://tex.z-dn.net/?f=0.626g%2Fcm%5E3%3D%5Cfrac%7B35.0g%7D%7B%5Ctext%20%7BVolume%20of%20pentane%7D%7D%5C%5C%5C%5C%5Ctext%7BVolume%20of%20pentane%7D%3D55.9cm%5E3%3D55.9ml)
(Conversion factor:
)
Hence, the volume of pentane is 55.9 ml
Answer:
The answer to your question is: letter B
Explanation:
First, write the reactions and balance them
a. 2 CH3OH + 3 O2 ⇒ 2 CO2 + 4 H2O
ratio 3/2 = 1.5
b. 2 CH2 = CHCH3 + 9 O2 ⇒ 3 CO2 + 3 H2O
ratio 9/2 = 4.5
c. 2 CH ≡ CH + 5 O2 ⇒ 4 CO2 + 2 H2O
ratio 5/2 = 2.5
B. The rate of diffusion increases with the increase in number of particles and temperature. Temperature increases particle speed, and more particles means there are more to move with the temperature.
YER MOM.... jk, <span>Gold is used to make jewelry because
of the attractiveness of its luster and because of its rarity. It also
doesn't tarnish and doesn't react with air the way a metal like iron
does. Gold is malleable, which means it can be beaten into very thin
sheets. It's also ductile, which means it can be stretched out into thin
wire as in the findings of earrings :3</span>
