Answer:
is there supposed to be a photo with this?
Explanation:
Answer: There are molecules of glucose.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the molecules, we use the equation:
Thus there are molecules of glucose.
Answer:
120 V usually but its not given in the option so 110 V
Answer:
0.3171 moles
Explanation:
The computation of the number of moles of gas in the drum is shown below;
The ideal gas equation is
PV = nRT
where
P denotes the pressure of the gas
V denotes the volume of the container
n denotes the number of moles of gas
R denotes the Gas constant
T denotes the temperature
Also P proportionate to n
Now the following formula should be used
P_1 ÷ P_2 = n_1 ÷ n_2
742 ÷ 759 = 0.31 ÷ n_2
n_2 = 759 × 0.31 ÷742
= 0.3171 moles
Answer: <span>B. a nonpolar molecule
</span>Water is a molecule made of two hydrogens and one oxygen. Water structure looks like a mickey mouse which makes it polar.
A polar compound will attract others polar molecules. That cause a polar substance will have much more solubility in water than non-polar substance like oil. Since the substance is not dissolved in water, it is more likely for it to be a non-polar molecule.
