A dog meets all the characerisitcs of life in the following ways - they maintain homeostatis, are made of cells, breathe and have a metabolism, are able to reproduce, pass their traits off to their offsp they grow and change, and and respond to their environment.

Answer:1Zn+2HCl------1ZnCl2+1H2
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus zinc can easily lose electrons as compared to hydrogen and result in the formation of zinc chloride and hydrogen.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Answer:
Subtract 4x4x from both sides of the equation.
y=16−4xy=16-4x
2x+3y=−22x+3y=-2
Replace all occurrences of yy in 2x+3y=−22x+3y=-2 with 16−4x16-4x.
y=16−4xy=16-4x
2x+3(16−4x)=−22x+3(16-4x)=-2
Simplify 2x+3(16−4x)2x+3(16-4x).

The solution to the system of equations can be represented as a point.
(5,−4)(5,-4)
The result can be shown in multiple forms.
Point Form:
(5,−4)(5,-4)
Equation Form:
x=5,y=−4x=5,y=-4

4x+y=16,2x+3y=−24x+y=16,2x+3y=-2
