Which has more calories: table sugar or aspartame?
Alina [70]
Aspartame produces 4 kilocalories of energy per gram when metabolized, While table sugar produces 3.9 kilocalories. However, aspartame is approximately 200 times sweeter than table of sugar, so it is consumed in much smaller doses. Then we can say that they're pretty much the same

What is the pH of a solution that has a hydroxide ion concentration of 1.0×10−9 M?
bogdanovich [222]

Answer:

\boxed{\text{pH = 5.00}}

Explanation:

Step 1. Calculate the pOH

pOH =-log[OH⁻]

pOH =-log(1.0 × 10⁻⁹)

pOH = 9.00

Step 2. Calculate the pH

pH + pOH = 14.00

pH + 9.00 = 14.00

\boxed{\textbf{pH = 5.00}}

Based on the Hertzprung-Russell diagram, which statement is true? OA. Main sequence stars with low temperatures tend to have low
ololo11 [35]

Main sequence stars with low temperatures tend to have low luminosity is based on Hertzprung-Russell diagram

<h3>What is the Hertzsprung-Russell diagram's main sequence?</h3>

The bright, hot stars in the image's upper left are the main sequence group, which stretches roughly diagonally to the lower right (dim and cool). In the bottom left are white dwarfs, which are small, faint, and hot. In the top right are giant and supergiant stars, which are big, bright, and cool.

<h3>What is the main sequence star H-R diagram trend?</h3>

Main sequence stars have a wide range of effective temperatures, but because they are brighter at higher temperatures, they normally follow a band from the bottom right to the top left of the diagram. Inside the cores, hydrogen and helium are fusing together.
