Answer:
False, we cannot made 16 muffins from 3 eggs.
Explanation:
2 cups flour + 1 egg + 3 oz blueberries → 4 muffins
According top recipe, 2 cups of flour, 1 egg and 3 oz of blueberries are made into batter to give 4 muffins.
Then 16 muffins will made from:
For each muffin we need =
Then for 16 muffins we will need:
4 eggs will be required to make 16 muffins
From 1 egg we can made 4 muffins
Then from 3 eggs we can made = 3 × 4 muffins = 12 muffins
12 muffins will made from 3 eggs.
We cannot make 16 muffins from 3 eggs.

We first need to calculate how much energy is needed to ionize a single atom. So divide the kilojoules/mol energy value by avogadro's number.
342 kj/mol / 6.0221409x10^23 = 5.67904x10^-19 Joules
So we need a photon with 5.67904x10^-19 Joules of energy. The equation to express the energy of a photon is
E = hc/w
where
h = Planck constant (6.626070040Ă—10â’34 Js)
c = speed of light (299792458 m/s)
w = wavelength of photon
Solving for w
E = hc/w
Ew = hc
w = hc/E
Substituting known values
w = 6.626070040Ă—10^â’34 Js * 299792458 m/s / 5.67904x10^-19 J
w = 1.9864458x10^-25 Jm / 5.67904x10^-19 J
w = 3.497855x10^-7 m
w = 3.50x10^-7 m
w = 350 nm</span>
Answer:
1.89 × 10³ J
Explanation:
Step 1: Given data
- Heat of fusion (ΔH°fus): 126 J/g
- Mass of the sample (m): 15.0 g
Step 2: Calculate the heat (Q) required to melt the sample
The fusion is the phase change from solid to liquid. We can calculate the heat required for the fusion of the sample using the following expression.
Q = ΔH°fus × m
Q = 126 J/g × 15.0 g
Q = 1.89 × 10³ J
