The equation shows neutralization of an acid and a base to produce a salt and water.

2HCl + Na2O → xNaCl + H2O

Which value of x will balance the equation?

a car slows down - 27.7 m/s to - 10.9 m/s "while" undergoing a displacement of - 105 m what was its acceleration

How would you explain to someone that it's possible to have more than one full moon in a month?

Give an example of something moving that is not accelerating

Two identical isolated conducting spheres are picked for an experiment. Only one of them is charged. If the spheres are now briefly brought into contact and then separated by a small distance, the two spheres would experience

A Ping-Pong ball has a diameter of 1.99 cm and average density of 0.121 g/cm3. What force would be required to hold it completely submerged under water? The acceleration of gravity is 9.8 m/s 2. Answer in units of N.

If an object moving in one direction slows down, then the direction of its acceleration is the same as the direction of its motion.

How long does it take for light to travel from the sun to earth?

Two very small spheres are initially neutral and separated by a distance of 0.30 m. Suppose that 2.50 1013 electrons are removed from one sphere and placed on the other. (a) What is the magnitude of the electrostatic force that acts on each sphere?

Why is it important to balance a chemical equation? A. It is not important to balance a chemical equal B. To make sure you have the correct products C. To make sure you have the correct reactants D. To obey the law of conservation of mass

The presence of icicles hanging off the eaves of a wood-framed structure is most likely due to: heavy snow followed by a thaw. improper insulation in wall cavities. use of a poor-quality roof sheathing material. lack of proper roof ventilation.
