A because cation is positive and anion is negative evening it out at constant.
•The earth weighs-5.972 × 10^24 kg
•The sun is 94.079 million miles away
•A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.
•Airplanes fly because they are able to generate a force called Lift which normally moves the airplane upward. Lift is generated by the forward motion of the airplane through the air. This motion is produced by the Thrust of the engine.
•Flies need sticky feet to walk on ceilings, but not so sticky that they get stuck upside down. So each foot comes with a pair of claws that help hoist the gooey foot off the wall. Flies use several different techniques to get unstuck: pushing, twisting, and peeling its footpads free
•rainbows are made by the refraction of light particles
•sharks are not mammals since they are cold blooded
Answer:
9
Explanation:
To balance the equation, we need to supply the number of missing coefficients.
There are 2 moles of aluminium on the right hand side, so automatically we need to multiply the number of moles of aluminium by 2 on the left hand side.
There are 3 sulphate ions on the right hand side so we need to multiply the number on the left by 3.
And lastly since we have 6 hydrogen molecules on the left hand side now, we need to multiply the hydrogen on the right hand side by 3 to give 6
The set of coefficients = 2 3 1 3
Adding all thus yields 9
