Answer:
Methanol and butanol are alcohols. Alcohols have the same_______________ as alkanes and the __________ identifies the compound as an alcohol.
Explanation:
Alcohols belong to a group of organic compounds which contain -OH group as the functional group.
So alcohols have the same carbon -hydrogen bonds as alkanes and the -OH functional group identifies the compound as an alcohol.
Answer:
978mmHg
Explanation:
The total pressure of a gas mixture is defined as the sum of the pressure of each gas in the mixture.
If the mixture of gases you have 200mmHg for O₂, 350mmHg for N₂ and 428mmHg for He, total pressure of the mixture is:
200mmHg + 350mmHg + 428mmHg = <em>978mmHg</em>
Answer:

Explanation:
We are asked to find the density of a metal. Density is the mass per unit volume. It is calculated by dividing the mass by the volume.

The mass of the metal sample is 24.64 grams and the volume is 5.91 milliliters. We can substitute these values into the formula.

Divide.

The mass measurement has 4 significant figures the volume measurement has 3 significant figures. Our answer for density must match the least number of significant figures, which is 3.
For the number we calculated, that is the hundredth place. The 9 in the thousandth place tells us to round the 6 up to a 7.

The density of this metal is approximately <u>4.17 grams per milliliter.</u>
Answer:
Physical change
Explanation:
The molecules are being rearranged as the water changes phases from liquid to gas, but this doesn't change the chemical structure of the water.
<h3>Answer:</h3><h2>NADPH and ATP</h2><h3>Explanation:</h3>
When the light absorbs by the photosynthetic apparatus, the water molecules break down to produce essential material to continue the photosynthetic cycle as electron and H-ions. The H-ions becomes stored in thylakoid chamber and passed through the ATP synthetic machines to refill the ADP or AMP molecules. The generated electron passes through the various stages of photosynthetic series to finally produce the NADPH which also acts as energy transfer compound. At the PSI, the electron transfer to the NADP to generate NADPH.
