Answer:
water
Explanation:
liquid don't have any shear strength and so a shear wave cannot propagate through a liquid.
The answer for the following question is mentioned below.
+3
→2
+2 
the equation is balanced.
Explanation:
The steps required to balance a chemical equation is:
Firstly,write the formula of the compound/substance.
Secondly,count the number of atoms in each element on each side of the equation
Thirdly,Adjust the co-efficient.Balance the atoms or the ions present in the greatest number.
You may do this by finding the lowest common multiple of two.
Continue systematically to balance the atoms or ions on the rest of the side (i.e.)on the other side.
Lastly,check the number of atoms each elements is same on both the sides
From the equation:
Before balancing the equation:
+
→
+ 
After balancing the equation:
+3
→2
+2 
Therefore the given equation is balanced.
S because As is not a non-metal
That is called an unsaturated solution
Answer:
The answer is 54g of mass
Explanation:
Using the formula
n = m/Mm
n - mole
m - mass
Mm - molar mass
Since we are given the mole of water to be 3
Let's calculate the molar mass of H2O
H is 1
O is 16
Mm = 1* 2+ 16
= 2 + 16
= 18g/mol
Using the formula above,
n = m /Mm
n = 3
m = we are looking for
Mm = 18g/mol
3 = m / 18
so, m = 18*3
= 54g
