Answer:
Regularly test the water in residents' homes.
Explanation:
The only way to know if tap water contains lead is to do tests to determine the levels of that metal in the water. Therefore, the state is under an obligation to constantly conduct such tests in the resident´s homes and thus determine whether the water supplied is fit for human consumption.
The state after the tests must guarantee the population the treatment of the water to reduce the levels of lead. The main pipes that contain lead pipes must be changed, as well as those parts of the service connections made of lead.
Explanation:
The given data is as follows.
Thickness (dx) = 0.87 m, thermal conductivity (k) = 13 W/m-K
Surface area (A) = 5 
, 
According to Fourier's law,
Q = 
Hence, putting the given values into the above formula as follows.
Q =
= 
= 5902.298 W
Therefore, we can conclude that the rate of heat transfer is 5902.298 W.
Answer: What is the mass, in grams, of 135 mL of ethanol? d=0.789 g/mL - the ethanol density. V=135 mL - the volume of ethanol. m=0.789g/mL*135mL=106.515g ~ 106.5g- the mass of ethanol.

Hope this helps :)
Answer:
the acceleration i think is 10
Explanation:
5x10=50
Covalent since they are both non metals, a metal and a non metal make an ionic bond
