As soon as the metal gets into the water a temperature transfer will start between both of them resulting in
1. Metal will cool down.
2. Some water will get evaporated.
3. Temperature of water will rise.
4. As the metal gets into the water, a sound like chissssss will be heard.
Hope it helps.
Don't be shy and say thx.<span />
Your chemical formula of glucose is messed up. It is C6 H12 O6.
So, to get it, you simply multiply the number of atoms of C H and O by their atomic weights each and add all of them together to get the molar mass of glucose.
Answer:
1.67x10^23 atoms
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 atoms.
This means that 1mole of gold contains 6.02x10^23 atoms.
1 mole of gold = 197g
197g of gold contains 6.02x10^23 atoms.
Therefore, 54.5g of gold will contain = (54.5 x 6.02x10^23) /197 = 1.67x10^23 atoms
Answer:
Newton's First Law states that an object with no net force acting on it remains at rest or moves with constant velocity in a straight line. Newton's Second Law states that the acceleration of an object is directly proportional to the net force on the object and inversely proportional to the mass of the object. His First Law of Motion states that an object in motion tends to stay in motion unless another force acts upon it. This law is sometimes confused with the principles in his second law of motion, which states the relationship among force, mass and acceleration.

Answer:
23.2 kJ of energy are released by the reaction.
Explanation:
Hello there!
In this case, according to the given information, it turns out firstly necessary for us to calculate the moles of both tin and nitrogen and the produced moles of Sn3N4 product by each reactant as shown below:
Thus, since 13.1 grams of tin produce the fewest moles of Sn3N4 product, we infer tin is the limiting reactant, and the correct produced energy, due to this reaction is:
