Suppose that we want to prepare 1 L of a 0.400 M HCL solution from a solution of 1.00 M HCL

Use 0.400 L of the 1.00 mol·L⁻¹ solution.  

Explanation:

We can use the dilution formula to calculate the volume needed.

V₁c₁ = V₂c₂

Data:

V₁ = 1 L; c₁ = 0.400 mol·L⁻¹;  

V₂ = ?;  c₂ =   1.00   mol·L⁻¹;  

Calculation:

- decrease the number of plants and animals living in the water.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
