Intake
divide the total amount of calcium 1200mg by the amount of calcium in one cup of milk 306mg and you will find that she needs about 4 cups of milk. To calculate the milliliters you need to know how many milliliters is one cup (1cup= 236.588 mL) and multiply by the number of cups that you calculate first.
Answer:
A
Explanation:
the answer is a because the sun cannot stop burning but will rather burn hotter Then decay amongst the atoms in space

Answer: c
. Alkaline earth metals (Group 2)</h2>
<h3>
Explanation:</h3>
Group 2 metals have 2 electrons in their outer shell. These two electrons are usually found in the s orbital, hence the s².
Answer:
Explanation:
As per Boltzman equation, <em>kinetic energy (KE)</em> is in direct relation to the <em>temperature</em>, measured in absolute scale Kelvin.
Then, <em>the temperature at which the molecules of an ideal gas have 3 times the kinetic energy they have at any given temperature will be </em><em>3 times</em><em> such temperature.</em>
So, you must just convert the given temperature, 32°F, to kelvin scale.
You can do that in two stages.
- First, convert 32°F to °C. Since, 32°F is the freezing temperature of water, you may remember that is 0°C. You can also use the conversion formula: T (°C) = [T (°F) - 32] / 1.80
- Second, convert 0°C to kelvin:
T (K) = T(°C) + 273.15 K= 273.15 K
Then, <u>3 times</u> gives you: 3 × 273.15 K = 819.45 K
Since, 32°F has two significant figures, you must report your answer with the same number of significan figures. That is 820 K.
