I would except daughter fruit flies to have 8 chromosomes because that’s how many the adult has
Unfortunately I don't work with the same units as put forward in this question but the equation I use for this is:
pressure*volume = moles*8.314*temperature
The units required for this equation are:
pressure in pascals
temperature in Kelvin
volume in m³
If you convert the units in the question to the units for this equation, you'll be able to work out the volume of oxygen gas in m³
Answer: Y → Z → X
Explanation:
The three states of matter shown in the picture are:
X) solid - in solids, molecules are bond together, so they are not free to move. They can only vibrate about their position - therefore they have the least freedom of motion
Z) liquid - in liquids, molecules are not bond, so they can move past each other. However, there are still strong intermolecular forces that keep the molecules close to each other, so they are not completely free to move - so this is the intermediate amount of motion
Y) Gas - in gases, molecules are completely free to move, since the intermolecular forces between them are negligible. Therefore, this is the state where molecules have the greatest amount of motion
A. The mass of one mole of the virus is calculated by multiplying the mass of a single virus by the Avogadro's number which is equal to 6.022 x 10^23. Performing this operation,
mass = (9.0 x 10^-12 mg)(6.022 x 10^23) = 5.42 x 10^12 mg
In correct number of significant figures, the answer would only have to be 5.4 x 10^12 mg.
b. The number of moles of the virus that will have the same mass as the oil tanker is calculated by dividing the mass of the oil tanker by the mass of one mole of the virus. Note that doing division, both would have to have the same units.
n = (3.0 x 10^7 kg) / (5.4 x 10^12 mg)(1 g/1000 mg)(1 kg/1000 g)
Simplifying,
n = 6
In correct number of significant figures, the answer is 6.0.
Answer:
ethanoic acid
Explanation:
For two carbon atom used eth
For saturated hydrocarbon or C-C single bond used ane means name is eth +ane = ethane
For –COOH used -oic acidby Replace the –e ending so the name becomes ethanoic acid
