Answer:
A. Up
B. Out
C. Out
D. To equilibrum
Explanation:
a. The reaction in an exothermic reaction so this means heat is given off. If the cylinder is thin enough heat will transfer to the water bath
b. Since the products will create heat which will increase pressure, the piston in an attempt to maintaining a constant pressure will move up to accommodate building pressure.
c. Heat will flow out of the gaseous mixture as this reaction creates heat as a product as well
d. Heat will flow out in the capacity to create an equilibrium with the water bath that it is in.
The correct answer is a liter.
The SI or the International System of Units illustrates seven measuring units as a fundamental set from which all the other SI units can be obtained. The SI base units and their physical quantities are the kilogram for mass, the meter for measurement of length, the ampere for electric current, the second for time, the candela for luminous intensity, the Kelvin for temperature, and the mole for the amount of substance.
Multiply straight across! 3*5*2=30, and 4*6*5=120. So, the answer is 30/120, or 1/4.
Answer:
Explanation:
a) Zinc has a charge of plus 2 and hydrogen gas is H₂ so HCl would have a two in front to balance the equation
b) All have charges of plus one
c) Copper has a charge of plus two (given) and it needs two chlorine atoms to become stable and hence to balance the whole equation, you would need two moles of sodium hydroxide and sodium chloride
