The SI base units for length is meter (m) and for time is seconds (s).
The given ratio is 
Converting mm/s to m/s as:
Since, 1 mm/s = 0.001 m/s
So, 
Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of to three significant figures and answer in SI units is 
.
Answer:
5118.50 J
Explanation:
pΔv=nRΔT ;
therefore, ΔT=PV/nR
ΔT = (6.4×10^5)(3.2×10^(-3)/1×8.314
ΔT= 2.4633×10^2 = 246.33 K
specific heat at constant pressure is given as:
c_p = 3/2R
c_p = 12.5 J/mol K
Now, substitute in equation (1)
we know that
Q=ΔU+W ;
and
W=pΔV= 6.4×10^5×3.2×10^(-3) = 2048 J
now
ΔU=CvΔT = 12.465×246.33 =3070.50 J ;
therefore
Q=3070.50+2048= 5118.50 J
It is important for scientists to have a standard system of naming compounds and other chemical procedures to avoid ambiguity in the nomenclature of chemical compounds and procedures.
Chemicals may be referred to by various names among various scientists in different places. These different names creates confusion when scientists present their discoveries to other scientists outside their locality.
Therefore, it is imperative that a unified and standard system of nomenclature should be devised so that all scientists can have the same name for compounds. This reduces ambiguity associated with the nomenclature of chemical substances and procedure.

To answer this question, you need to know the equation for the reaction. The equation should look like this:
<span>2K3PO4 (aq) + 3NiCl2 (aq) --> Ni3(PO4)2 (s) + 6KCl (aq)
</span>
In the equation, 2 K3PO4 would react with 3 NiCl2. Then the calculation should be look like this:
V2= V1*m1/m2 *2/3
V2= 134ml * <span>0.0112/</span>0.225 *2/3
V2= 4.46ml
46.0684g I think because you have to concert grams to moles or moles to grams
