Length: The most common units that we use to measure length in the metric system are the millimeter, centimeter, meter, and kilometer. The millimeter is the smallest commonly used unit in the metric system
Mass: Kilogram.
Liquid volume: The basis of fluid volume units for the metric system is the liter. A liter is about the same as one quart.
- The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have.
- A dependent variable is what the experimenter observes to find the effect of systematically varying the independent variable.
- Experimental constants are values that do not change either during or between experiments.
- A controlled variable is a variable that could change, but that the experimenter intentionally keeps constant in order to more clearly isolate the relationship between the independent variable and the dependent variable.

Strong acid on combining with strong base will always give neutral solutions. Consider the following example for the same
HCl + NaOH ↔ NaCl + H2O
(strong (strong
acid) base)
In above case, the resultant solution is neutral in nature.
On other hand, weak acid will react with strong base to form salt and water. But the solution will be basic in nature. Also, strong acid will react with weak base to form salt and water. But the solution will be acidic in nature
Answer:
Water-gas A mixture of carbon monoxide (CO) and hydrogen (H2) produced by passing steam over red-hot coke using the endothermic reaction C + H2O # CO + H2.
Explanation:
K, ca, sc is the right answer. Take a look at table S of your chemistry reference table.
