Answer:
As mass increases the gravitational force increases
Explanation:
Things with mass gain a gravitational force, The bigger they are the more force, for example: the sun is the biggest so it pull us
Answer:
Sodium oxide is the product
Explanation:
4Na+O2->2Na2O
Answer:
1.0625 g
Explanation:
Number of moles in 5g of NH4NO3 = 5.0g/80g/mol = 0.0625 moles
Again the balanced reaction equation is;
NH3 + HNO3 → NH4NO3
So,
1 mole of NH3 yields 1 mole of NH4NO3
x moles of NH3 yields 0.0625 moles of NH4NO3
x = 0.0625 moles of NH3
Mass of NH3 = number of moles * molar mass
Mass of NH3 = 0.0625 moles * 17g/mol
Mass of NH3 = 1.0625 g
Answer:
"Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings of the reaction."
