Answer:
heat energy
Explanation:
water in the sun begins to get hot
Answer:
the answer is 2.75 but since that isn't an option I'd go with 1 because I just took a test with this question and it was the right answer.. hopefully that helps
Applied forces/or unbalanced:i hope that helps you
Explanation:
Scientist Evidence Model
Dalton Gases indivisible, solid and spheres
J.J Thomson Deflected beam Negative charges evenly scattered
through positively charged mass of
matter.
Rutherford Deflection of alpha atomic model
particles passing
through the gold foil
The emboldened words are the answer.
- John Dalton proposed the first model of the atoms by his works on gases. He postulated the Dalton's law of partial pressure.
- He suggested that gases are made of tiny particles called atoms.
- J.J Thomson proposed the plum pudding model of the atom in which the charges are evenly scattered through the positively charged mass of matter.
- The gold foil experiment by Rutherford brought the atomic model of the atoms in the front-light.
- The model suggests a small positively charged center which the mass of the atom.
- The outer space is occupied by the electrons.

2HF + Na2SiO3 ----> 2NaF + H2SiO3 is the balanced equation.
2 moles of HF form 2 moles of NaF
therefore 0.508 Mol HF forms 0.508 mol of NaF
In grams this is 0.508( rel atomic mass of Na + RAM of F)
= 0.508 (22.99+19)
= 21.33 grams
