Answer:
3.56x10²³ atoms
Explanation:
To solve this question we need first to determine the moles of iron (II) chloride, FeCl₂, using its molar mass. Then, using Avogadro's number we can solve for the number of atoms:
<em>Moles FeCl₂ - Molar mass: 126.751g/mol-</em>
25g FeCl₂ * (1mol / 126.751g) = 0.1972 moles
<em>Number of atoms:</em>
1 mole of FeCl₂ are 6.022x10²³ molecules of FeCl₂, that means 0.1972moles are:
0.1972mol * (6.022x10²³ molecules / 1mol) = 1.188x10²³ molecules of FeCl₂
In 1 molecule of FeCl₂ there are 3 atoms (1 of Fe and 2 of Cl), in 1.188x10²³ molecules of FeCl₂ there are:
1.188x10²³ molecules of FeCl₂ * (3atoms / molecule) =
<h3>3.56x10²³ atoms</h3>
Answer:
A. Move to safe location
Explanation:
Plants and animals form the living community of the environment. Both of them share some of the common characteristics. Both are made of cells and they use energy for their growth and development. One of the differences between the two lies in the ability to move from one place to another. Animals have legs with which they can easily move from one place to another in search of food, shelter, and safety. While plants are unable to move as they are fixed in one place.

Answer:
5.3 × 10^-4 m or 0.0000053m
Explanation:
Wavelength is given by 2L/m
Where m is the waves bewtween the cavity mirrors which is 100000
L is the cavity length which is 53.00 cm
53/100 (convert to meter) =0.53m
Therefore the wavelength is (2 × 0.53m)/100,000
=0.0000053
= 5.3 × 10^-6 m
